Governor Andrew M. Cuomo announced the New NY Bridge has reached a major milestone with the topping off of the eight main span towers. The New NY Bridge is on track to open in 2018 and on budget at $3.98 billion.
The project team is looking forward to another year of progress on the twin-span replacement of the original Tappan Zee Bridge, including the completion of the westbound span.
Motorists on the Tappan Zee Bridge may be familiar with the rhythmic bumps in the existing bridge’s roadway. These interruptions are the result of nearly 200 expansion joints, which are designed to absorb the slight expansion and contraction of the bridge’s steel and concrete. Drivers can expect a much smoother ride in the future thanks to the dramatic reduction of expansion joints on the new bridge.
The New NY Bridge project team is supporting local charities to make the holidays a little more joyous for those in need in our communities.
Frequently Asked Questions
Q:
How will the project reduce traffic congestion? 
A:
The existing bridge has only seven lanes, some of which are narrower than the current standard lane width of 12 feet. The new bridge will have eight, 12-foot-wide lanes and wider shoulders. The shoulders of the new crossing will greatly reduce the traffic impact of disabled vehicles and accidents, which can cause massive tie-ups on the existing bridge. The incline approaching the main span will not be as steep, allowing large trucks to maintain consistent speed and reduce engine and braking noise. The ability of trucks to maintain highway speed will also reduce speed differential with passenger vehicles which lessens lane changes and potential for accidents. There will also be gently banked curves to further smooth traffic flow and reduce accidents. In addition, the new bridge is being built with space to accommodate dedicated bus lanes. In April 2016, cashless tolling went into effect on the existing bridge, and this will be a feature of the new bridge, eliminating the need for eastbound drivers to slow down or stop and idle at a toll plaza.

The new bridge’s iconic main span towers are nearing completion thanks to the around-the-clock efforts of the hard-working men and women of Tappan Zee Constructors.
Following South Nyack’s overwhelming endorsement of “Alternative F” in March, the New NY Bridge project team has been working with Mayor Bonnie Christian and the village’s Tappan Zee Bridge task force on the design of the Rockland end of the shared-use path.
Tappan Zee Constructors recently installed the first of 18 overhead gantries, which will be equipped with enhanced technology to help keep traffic moving safely and efficiently on the new bridge.
The New NY Bridge project is standing united this Veterans Day to honor all those who have served in the U.S. military.  Veterans are among the thousands of skilled individuals who have made possible the remarkable progress taking place on the Hudson River.
Frequently Asked Questions
Q:
Why does the current Tappan Zee Bridge need to be replaced?        
A:
The Governor Malcolm Wilson Tappan Zee Bridge opened to traffic in 1955 and is a vital artery for residents, commuters, travelers and commercial traffic. The bridge, which was designed to carry up to 100,000 vehicles per day, currently handles an average of 140,000 vehicles daily, and traffic congestion and delays are regular occurrences. Heavy traffic, narrow lanes and the lack of emergency shoulders often contribute to congestion and frustration for motorists. As a result, the bridge has twice the average accident rate per mile as the rest of the 570-mile Thruway system. In recent years, hundreds of millions of dollars have been spent to maintain and repair the bridge. If the current bridge were not being replaced, the Thruway Authority would need to spend an additional $3 billion to $4 billion over the next 20 years to ensure its structural integrity.

Tappan Zee Constructors, LLC (TZC) is one step closer to completing the twin-span crossing as the new bridge’s westbound towers reach their ultimate height, 419 feet above the Hudson River. Crews are putting the finishing touches on the upper sections of the towers and removing the blue jump forms when the operations are complete. TZC is scheduled to complete all four westbound towers within the coming weeks.

While the large and powerful I Lift NY super crane continues to raise enormous, 410-foot sections of steel above the Hudson River, a far smaller and swifter machine, called a derrick crane, is hard at work on an equally important task – installing hundreds of road deck panels to form the base driving surface of the bridge.

As the New NY Bridge project continues to makeremarkable progress above the Hudson River, crews are installing several safety features on the crossing.
These features are the result of the project’s close collaboration with local and regional first responders during the bridge’s design development phase.

Prior to the start of New NY Bridge construction in 2013, Rockland and Westchester residents living near the project site voted overwhelmingly in favor of new permanent barriers to reduce highway traffic noise. Today, progress on the barriers is readily apparent in South Nyack.

The first full closure of the main navigational channel occurred this September. Approximately 70 closures are anticipated through the end of 2017 as project crews install new sections of structural steel and road deck panels between the towers of the new crossing.
Frequently Asked Questions
Q:
How many lanes will the new bridge have?       
A:
The new twin-span bridge will have eight general traffic lanes – four in each direction. Space will also be provided for disabled vehicles, emergency responders and express buses and/or bus rapid transit. There will also be a shared-use path for bicycles and pedestrians.

Three Years in Two Minutes

New Video Captures Construction Progress

The New NY Bridge project has become a symbol for what the state can accomplish.

Watch the new twin-span crossing take shape during the past three years in this new time-lapse video. From steel girders to concrete towers, from piles to road deck, from shoreline to shoreline, the transformation has been amazing.

Initiated by Gov. Andrew M. Cuomo, the 3.1-mile New NY Bridge project is one of the largest active projects of its kind in the nation.

The time-lapse video debuted today as part of Governor’s Day at the Great New York State Fair in Syracuse, a 12-day celebration that shares the best that New York State has to offer. For those visiting the State Fair, you can check out the video at the Governor’s booth.

The video is also available on the New NY Bridge project’s YouTube page.

Those interested in a closer look are also invited to view the daily project progress via the project’s webcams and photo gallery as well as by visiting the New NY Bridge construction viewing platforms at Scenic Hudson RiverWalk in Tarrytown and Memorial Park in Nyack.

Project Update: STAY CABLE INSTALLATION CONTINUES

TZ

For immediate release: August 4, 2016

STAY CABLE INSTALLATION CONTINUES
Work Progresses on Main Span

Tappan Zee Constructors, LLC (TZC) continues to install the new northbound bridge’s stay cable system. The stay cables are comprised of numerous metal strands, tightly packed in a protective sheath. After the initial installation process, TZC will install additional strands inside the sheath to provide further strength.

TZC will install new structural steel sections and stay cables on alternating sides of the towers as work continues. Precast concrete deck panels will also be placed in the erected steel sections to provide a base driving surface.

Maintenance Dock Construction
TZC will continue constructing a New York State Thruway Authority maintenance dock near the new bridge’s Rockland landing. The work involves partially dismantling the existing work trestle that was used to construct the northern span of the new bridge. Work will take place during daytime hours. The construction efforts are expected to conclude later this year.

Noise Barrier Construction
TZC will continue constructing noise barriers along the New York State Thruway (I-87/I-287) in South Nyack next week. The work includes constructing noise barrier foundations and excavating soil along the southbound Thruway between the South Broadway bridge and River Road. After the foundations are established, concrete panels that form the noise barriers will be installed. The barriers will be treated with sound-absorbing material to further reduce traffic noise in the nearby community.

TZC also will continue constructing foundation walls for the future highway and shared-use path along the northbound Thruway in South Nyack. The operation is scheduled to continue in the coming months.

Additional work includes:

  • Main span tower construction
  • Support for river-based work from the Rockland trestle
  • Rockland landing retaining walls
  • Survey inspections on the existing bridge
  • Utility work at the Westchester landings
  • Girder assembly placement
  • Bridge road deck installation
  • Drainage structure installations
  • Maintenance facility construction in Tarrytown
  • Soil boring in South Nyack

Boater Safety
Marine units are continuing patrols to monitor the construction zone and encourage all boaters to obey the established U.S. Coast Guard safety protocols.

The U.S. Coast Guard has established a Safety Zone surrounding 16 construction barge mooring locations at the project site. No unauthorized vessels are allowed in the Safety Zone. The U.S. Coast Guard also has established a safety zone encompassing all navigable waters within a 200-yard radius of the largest machine on the project, the I Lift NY super crane, legally registered with the U.S. Coast Guard as the Left Coast Lifter.

In addition, marine law enforcement will be enforcing the rules of the expanded Regulated Navigation Areas (RNAs) east and west of the Safety Zone. The RNAs stretch 500 yards north and 500 yards south of the existing bridge. The Eastern RNA will be extremely active and vessels transitioning to and from the eastern shoreline at Tarrytown should approach and depart to the north. The Western RNA will be impassable at times and mariners should stay clear of the area.

Boaters are strongly urged to use the center 600 feet of the main channel (when available) to navigate in a north-south direction with no wake at a maximum speed of five knots. Boaters should expect periodic partial closures of the main channel due to construction activities. Tune to Marine Radio Channel 22A for the latest U.S. Coast Guard advisories.

Mariners also should be aware that TZC will continue work in the vicinity of the side channels under the existing bridge. Mariners are advised to stay clear of all overhead work and maintain a safe distance of 1,000 feet from all construction equipment and support vessels. In addition, all bridge piers and abutments are protected by a 25-yard security zone.

Additional temporary navigational lights have been installed on the existing bridge to further define the 600-foot navigation channel under the main span. Permanent elements of the new bridge are lit per U.S. Coast Guard permit requirements, as are all moorings, barges and other equipment. All mariners should consult the latest USCG Local Notice to Mariners before transiting this area.

More New NY Bridge boater safety information, including the U.S. Coast Guard Notice to Mariners and construction site map can be found at NewNYBridge.com/Boater. The page includes an interactive GPS map showing vessel locations on the Hudson River, detailing which vessels are stopped and which are in motion to a new location, for recreational and commercial boaters to get current information on the very active construction zone. The vessel tracking map is for informational purposes and not intended for navigation.

All lane closures are subject to change due to traffic, weather or emergency situations. Please visit http://www.thruway.ny.gov/travelers/map/ for real-time information regarding traffic conditions.

The outline of the new twin-span crossing is emerging this summer as the project continues to make remarkable progress on the Hudson River. The Rockland and Westchester approaches continue to grow with rows of steel girders and hundreds of precast road deck panels. At the main span towers, crews are also installing sections of steel and roadway, and preparing the area for the new stay cable system.

The New York State Thruway Authority announced that Tappan Zee Constructors, LLC has completed installation of the first stay cables on the New NY Bridge project. The stay cables, along with the 419-foot towers, will be the most prominent features of the new 3.1-mile structure. The first two stay cables were installed by TZC on the new northbound bridge’s main span on Thursday, July 21, 2016.

In just half a year, Tappan Zee Constructors, LLC has transformed the New NY Bridge project site by connecting piers, installing road deck panels and doubling the height of the new main span towers. The iconic structures now rise above the existing Tappan Zee Bridge, with TZC preparing to install the first of nearly 200 stay cables.

With summer in full swing, the New NY Bridge project is making its most visible advancements to date. Those keen on observing the progress firsthand have a “front row seat” to the action, through the project’s viewing platforms and outreach centers in Tarrytown and Nyack.

The new bridge moved another giant step forward this month as Tappan Zee Constructors, LLC (TZC) installed the fourth and final concrete crossbeam on the main span. In addition to supporting the future road deck, the massive precast beams will reinforce the outward-angled towers as they grow to their ultimate 419-foot height.

Rockland and Westchester residents voiced their opinions at a pair of public meetings this March as the New NY Bridge team presented detailed information regarding the proposed alternatives for the Shared-Use Path (SUP) parking facilities and connections in the villages of South Nyack and Tarrytown.

Living up to its safety motto, “Take Zero Chances,” Tappan Zee Constructors, LLC (TZC) recently held safety meetings with every member of its New NY Bridge project crew.

Since the start of construction of the New NY Bridge in 2013, the project’s outreach team has partnered with local schools to engage nearly 40,000 students. The team’s presentations highlight the importance of science, technology, engineering and mathematics-collectively known as the STEM fields-to the design and construction of the twin-span bridge.
Frequently Asked Questions
Q:
What is Cashless Tolling, and when will it take effect on the Tappan Zee Bridge?    
A:
Beginning on April 23, 2016, the new cashless tolling system will allow motorists to pay their toll while maintaining highway speeds on the Tappan Zee Bridge. The system will collect tolls via E-ZPass or Tolls by Mail, detecting classes of vehicles and applying the correct charge.
If you have E-ZPass, your toll is collected using the same process that you are already familiar with. If you don’t have E-ZPass, cameras photograph your vehicle’s license plate as it passes under the overheard equipment. A bill is then automatically sent to the registered owner by U.S. Mail.

MAIN SPAN TOWERS REACH NEW MILESTONE

update

PROJECT UPDATE

For immediate release: Feb. 4, 2016

MAIN SPAN TOWERS REACH NEW MILESTONE
Overnight Lane and Ramp Closures on Southbound Thruway (I-87/I-287)

Next week, Tappan Zee Constructors, LLC (TZC) will begin the installation of four precast concrete crossbeams that will connect the new bridge’s main span towers and support its future road deck. The crossbeams were fabricated by Coastal Precast Systems in Chesapeake, Virginia, and barged to the project site last week. The precast materials will be set in place with the I Lift NY super crane, one of the few marine cranes in the world capable of the massive job.

Demolition of Thruway Maintenance Facility
TZC will begin demolition of the New York State Thruway Authority’s former maintenance offices in Tarrytown. Bridge maintenance teams currently operate from a temporary facility near exit 12 in West Nyack. The demolition will make way for a new maintenance facility and office building, which will begin construction this spring.

All-Electronic Toll Collection Gantry Work
Field testing of the project’s temporary all-electronic toll collection (AETC) system in Rockland will continue throughout the coming week near the exit 10 (Nyack – South Nyack – US Route 9W) and exit 11 (Nyack – South Nyack – US Route 9W) on-ramps to the southbound New York State Thruway (I-87/I-287).

The testing will necessitate closing the on-ramps during the overnights of Thursday, Feb. 4, through Friday, Feb. 12. Drivers will be directed to use the exit 12 (West Nyack – NY Route 303 – Palisades Center Drive) on-ramp from Route 303 in West Nyack, as shown in the graphic below. Signs will be posted to advise motorists of the detour route.

In addition, the work will require overnight closures of up to three lanes of the southbound Thruway throughout the remainder of this week and during the coming week. Specific lane and ramp closure times are detailed in the chart below.

The AETC system is expected to be activated this spring.

PROJECT UPDATE – WESTCHESTER GIRDER INSTALLATION

update

For immediate release: Nov. 19, 2015

WESTCHESTER GIRDER INSTALLATION OVER METRO-NORTH RAILROAD TRACKS CONTINUES THIS FRIDAY EVENING
Overnight Closures of the I-87/I-287 Exit 10 On-Ramp Scheduled for Nov. 19 and Nov. 20

Next week, Tappan Zee Constructors, LLC (TZC) will continue installing structural steel girder assemblies from the new bridge’s Westchester landing in Tarrytown. The assemblies will connect the future westbound span’s on-land abutment to the first offshore support pier in the Hudson River. TZC is installing the girders by literally pushing them west over the Metro-North Railroad Hudson Line’s tracks toward the first pier in the river, as seen in this animation. As the operation progresses, additional girders are being connected to the assembly and pushed farther westward. TZC is closely coordinating the effort with Metro-North Railroad, ensuring that the operation maximizes safety for both workers and the public and minimizes impacts to rail service.

With the entire operation anticipated to conclude by the end of the year, the remaining work over the Metro-North tracks will occur during two Friday overnights, with the next scheduled for this Friday evening, Nov. 20. Metro-North has adjusted its schedule slightly to allow the work to be completed. TZC will suspend construction activities when commuter trains pass through the area, resuming when given the “all clear” instruction by Metro-North.

Across the river, TZC has completed steel girder installation near the Rockland shoreline, connecting the new bridge’s abutment to already-installed support structures in the Hudson River.

The I Lift NY super crane will continue placing larger girders across the river, averaging two placements a week. A total of 31 miles of steel girders cumulatively weighing more than 100,000 tons will be installed for the new twin-span bridge.

All-Electronic Toll Collection Gantry Work
Construction of the project’s temporary all-electronic toll collection (AETC) system in Rockland will continue near the exit 10 (Nyack – South Nyack – US Route 9W) on-ramp to southbound New York State Thruway (I-87/I-287). The work will necessitate closing the on-ramp during the overnights of Thursday, Nov. 19 and Friday, Nov. 20. Drivers will be directed to use the on-ramp from Route 59 in Nyack, as shown in the graphic below. No lane closures are planned for this work next week.

Ramp Closures Near the Tappan Zee Bridge

DATE: CLOSURES BEGIN: CLOSURES END: LOCATION:
Thu., 11/19 9 p.m. – Ramp Closure 5 a.m., Fri., 11/20 Southbound I-87/I-287
exit 10 on-ramp
Fri., 11/20 9 p.m. – Ramp Closure 5 a.m., Sat., 11/21 Southbound
exit 10 on-ramp

Tower Construction
Construction will continue on the new bridge’s iconic towers, which will eventually rise 419 feet above the river. Innovative self-climbing jump forms enable TZC workers to build the towers in segments that progressively “jump” up from the foundations to their full height. Within the jump forms, workers assemble steel reinforcement cages that are then encased in concrete, one segment atop the previous one and so on. Eight towers will be constructed on the project’s football-field-long main span pile caps over the coming year, as seen in this animation.

Deck Panel Installation
TZC is continuing to install nearly 6,000 high-strength concrete deck segments for the new crossing’s approach spans. Project cranes are lifting the prefabricated deck panels into place atop previously-installed structural steel girders. The deck segments are prefabricated at an off-site location and barged down river from the project’s Port of Coeymans facility in Albany County. TZC will continue installing the approach span deck sections over the coming year.

Installation of Noise Barriers in South Nyack
Next week will see continued removal of the noise walls located along the northbound Thruway and the construction of foundations for noise barriers along the southbound Thruway between the South Broadway bridge and River Road in South Nyack. The work involves drilling holes into the soil to install the foundations. After the foundations are installed, concrete panels that form the noise barriers will be installed. The barriers will be treated with sound-absorbing material to further reduce traffic noise to the nearby community.

Additional work includes:

  • Support for river-based work from the Rockland trestle
  • Survey inspections on the existing bridge
  • Westchester landings utility work

Boater Safety
Westchester and Rockland Marine Units are continuing extensive patrols to monitor the construction zone and encourage all boaters to obey the established U.S. Coast Guard safety protocols.

The U.S. Coast Guard has established a Safety Zone surrounding 16 construction barge mooring locations at the project site. No unauthorized vessels are allowed in the Safety Zone. In addition, marine law enforcement will be enforcing the rules of the expanded Regulated Navigation Areas (RNAs) east and west of the Safety Zone. The RNAs stretch 500 yards north and 500 yards south of the existing bridge. Boaters are urged to transit the main channel with no wake at a maximum speed of 5 knots and to use extreme caution on the river at all times.

More New NY Bridge boater safety information, including the U.S. Coast Guard Notice to Mariners and construction site maps, can be found here at NewNYBridge.com. An interactive map showing vessel locations on the Hudson River is also available here for recreational and commercial boaters to get updated information on the very active construction zone. The GPS tracking map is for informational purposes and not intended for navigation.

Mariners also should be aware that TZC will continue work in the vicinity of the side channels under the existing bridge. Additional temporary navigational lights have been installed to further define the 600-foot navigation channel under the main span. Permanent elements of the new bridge are lit per U.S. Coast Guard requirements, as are all moorings, barges and other equipment.

All lane closures are subject to change due to traffic, weather or emergency situations. Please visit http://www.thruway.ny.gov/travelers/map/ for real-time information regarding traffic conditions.

As more and more piers are connected by steel-blue girder assemblies, the New NY Bridge project’s iconic towers continue to advance skyward.

As the summer turns to fall in the Lower Hudson Valley, progress continues to march forward on the New NY Bridge project. More and more of the high strength structural steel-blue girder assemblies are being placed across the Hudson River by Tappan Zee Constructors, LLC (TZC), largely with the help of the massive I Lift NY super crane. At both shorelines, however-where shallow waters prevent the use of the super crane-alternate methods were necessary, including the use of construction platforms. The Westchester landing posed a further shoreline challenge: how to safely install the girders over the Metro-North Railroad Hudson Line tracks?

While most of the new bridge’s steel-blue girder assemblies are being placed across the Hudson River with the barge-based I Lift NY super crane, the location from the Westchester landing to the first pier in the river is inaccessible to the monumental machine. Tappan Zee Constructors, LLC is using an innovative yet simple alternative method to install the girders in this area, as detailed in this video.

New NY Bridge fans looking for a firsthand view of construction from the Rockland shoreline now have a “front row seat” to the action. Nyack’s new fishing pier at Memorial Park is now open and offers spectators a sweeping view of the Hudson River and the bustling project site.

After successfully installing structural steel girders between the Westchester abutment and a nearby pier, Tappan Zee Constructors, LLC (TZC) moved forward with the next stage of operations this week. In a remarkable feat of engineering, crews carefully pushed the massive steel-blue materials further west, over the Metro-North Railroad Hudson Line and toward the next pier in the Hudson River.
Frequently Asked Questions
Q:
Why does the current Tappan Zee Bridge need to be replaced? 
A:
The Governor Malcolm Wilson Tappan Zee Bridge opened to traffic in 1955 and is a vital artery for residents, commuters, travelers, and commercial traffic. The bridge, which was designed to carry up to 100,000 vehicles per day, currently handles an average of 138,000 daily, and traffic congestion and delays are regular occurrences. Heavy traffic, narrow lanes and the lack of emergency shoulders contribute to congestion and frustration for motorists and can create unsafe driving conditions. As a result, the bridge has twice the average accident rate per mile as the rest of the 574-mile Thruway system. In recent years, hundreds of millions of dollars have been spent to maintain and repair the bridge. If the current bridge were not being replaced, the state would need to spend an additional $3 to $4 billion over the next 20 years to ensure its structural integrity.

BRIDGE BUILDERS PREPARE FOR POSSIBLE HURRICANE

BRIDGE BUILDERS PREPARE FOR POSSIBLE HURRICANE
Marine Construction Work Temporarily Halted for Safety

Tappan Zee Constructors, LLC (TZC) is preparing for the potential effects of Hurricane Joaquin, which forecasters say could hit the Hudson Valley region in the coming days. In advance of the storm’s approach, TZC is implementing its storm preparedness plans, temporarily halting marine construction operations and the movement of construction materials, while securing the job site to prevent possible storm damage. By closely monitoring weather conditions and taking appropriate action in advance, TZC will ensure both worker and public safety while minimizing any potential storm-related downtime on the project.

TZC’s inclement weather preparation protocols include having tug boats on the water at all times, inspecting and adjusting all mooring lines, inspecting crane barges and securing all equipment, moving the large majority of cranes to shallow water moorings and taking all smaller crew boats out of the water. Additionally throughout every storm, TZC uses video and GPS to monitor the entire fleet of project vessels from its security operations center.

Governor Andrew M. Cuomo today activated the State Emergency Operations Center in Albany to monitor severe weather that is anticipated to impact southern parts of New York State beginning today and potentially lasting through this weekend.
Additional New York State storm preparedness updates can be found here:
http://www.governor.ny.gov/news

The following construction operations planned for next week will proceed as weather allows:

Steel Girder Installation
TZC will continue installing steel girders near the South Nyack shoreline. Safely accomplishing the work will require reducing River Road to one lane during weekdays between 6 a.m. to 5 p.m. Flag persons will keep traffic moving by alternating the directional flow between north and south.

Smaller girder sections will be lifted into place by cranes from the Rockland trestle. Ironworkers then bolt together the girders and cross beams that will support the new bridge’s concrete road deck. In deeper water, the I Lift NY super crane will continue placing larger girders, averaging two placements a week.

A total of 31 miles of steel girders cumulatively weighing more than 100,000 tons will be installed for the new twin-span bridge.

All-Electronic Toll Collection Gantry Work
Construction of the project’s temporary all-electronic toll collection (AETC) system in Rockland County will continue next week with the installation of an overhead gantry above the exit 10 (Nyack – South Nyack – US Route 9W) on-ramp to southbound New York State Thruway (I-87/I-287). The work necessitates overnight double-lane closures throughout the coming week. Specific lane closures are listed in the chart below.

All planned work is subject to postponement due to weather conditions.

Steel Girder Assemblies As piers are finalized in the coming weeks and months, steel girder assemblies for the approach span of the new bridge will continue being installed by the I Lift NY super crane.

Installation of Noise Barriers in South Nyack Next week will see continued installation of foundations for noise barriers along the southbound Thruway between the South Broadway bridge and River Road. The work will involve drilling holes into the soil to install the foundations. After the foundations are installed, concrete panels that form the noise barriers will be installed. The barriers will be treated with sound-absorbing material to further reduce traffic noise to the nearby community.

River Road in South Nyack River Road utility work will continue over the coming week. The work may require reducing River Road to one lane at times. TZC flag persons will direct traffic as needed and additional signage as well as other safety measures will be in place.

Foundation Work on the New Bridge Marine crews are continuing work on bridge foundations next week by placing reinforcing steel and concrete in the piles, main span pile caps and approach span pile caps. The high-strength concrete is made on site by the project’s floating batch plants. Teams also will erect formwork for the cast-in-place pier columns, which eventually will support the new bridge’s road deck.

Crews also will continue working on the bridge’s landings at the Rockland and Westchester shorelines. The abutments, comprised of steel and concrete, will serve as strong bases where the new crossing meets the landside roadway.

Additionally, TZC will continue concrete placement for bridge foundations near the South Nyack shoreline. The concrete for this work is being acquired from local concrete suppliers and is delivered by truck to the Rockland trestle located off the Thruway’s southbound access ramp. Trucks exit the trestle to the Thruway via the northbound access ramp. The access ramps are used only by construction vehicles, providing a safe route directly to the work site and reducing traffic impacts on local roads.

Additional work includes:

  • Girder installation
  • Pile cap foundation construction
  • Main span foundation construction
  • Landing abutment concrete work
  • Support for river-based work from the Rockland trestle
  • Survey inspections on the existing bridge
  • Westchester Landings utility work

All lane closures are subject to change due to traffic, weather or emergency situations. Please visit http://www.thruway.ny.gov/travelers/map/ for real-time information regarding traffic conditions.

New York State Thruway Authority Acting Executive Director Robert L. Megna today announced that the state has decided to relocate the bike/pedestrian path for the New NY Bridge project in Rockland County in order to reduce the impact on local residents and the neighborhood. As a result, the path will no longer end at the corner of Cornelison Avenue and South Broadway in the Village of South Nyack.

“We believe this decision is a good example of how the state can rebuild critical infrastructure in a timely, cost-effective manner while still being sensitive to community concerns,” Megna said. “We will continue to do everything possible to make the New NY Bridge the most open, inclusive and transparent infrastructure project in New York history.”

At Governor Andrew M. Cuomo’s direction, Megna, Deputy Director for State Operations Joe Rabito and the entire New NY Bridge project team have been working closely with South Nyack Mayor Bonnie Christian and the village’s Tappan Zee Bridge Task Force to find an alternate solution that will benefit the community and future users of the path.

They will continue to work with the village and task force on other options for the path, including ones that include extending the path into interchange 10 on I-87/287 and away from the residential neighborhood nearby.

“This decision is a victory for the residents of South Nyack who voiced their concerns about the impact of the shared-use path on their quality of life and we couldn’t be happier,” said Mayor Bonnie Christian. “I’d like to personally thank Governor Cuomo and his entire team for listening to our concerns and taking action on our behalf.”

A recent parking demand study estimated that 151 parking spaces – 54 in Rockland and 97 in Westchester – are needed to accommodate visitors to the path when it opens in 2018. In Westchester, the Thruway Authority has ample space for parking and amenities at 333 South Broadway in Tarrytown, the site of the old New York State Police Troop T facility that is being relocated as part of the bridge replacement project. Today’s decision clears the way for the 54 spaces and amenities in Rockland to potentially be created on existing Thruway Authority property at interchange 10 in South Nyack.

The New NY Bridge Community Benefits Program has approved a $250,000 grant for the Village of South Nyack to study the feasibility of redesigning and redeveloping interchange 10 on I-87/287. The village is now considering several proposals from consulting firms on the best design and economically feasible concepts.

“The new Tappan Zee Bridge will attract many new visitors to enjoy the beautiful Lower Hudson Valley,” said Congresswoman Nita Lowey. “I’m pleased Governor Cuomo and Mayor Christian’s solution for the shared use path capitalizes on this enormous economic opportunity for Rockland County while preserving quality of life for the residents of South Nyack. As a major supporter of this project in Washington, I will continue to ensure all parties work in close collaboration to make this bridge a success.”

Rockland County Executive Ed Day stated, “My administration is extremely supportive of this agreement. I am proud of the county’s role in stimulating positive discussions between state and local officials that resulted in a unified solution for a shared use path that will provide an exciting amenity for Rockland residents and visitors alike. I will continue to work collaboratively with Governor Andrew Cuomo and South Nyack Mayor Bonnie Christian to make the New NY Bridge an extraordinary Hudson River gateway to our county.”

Senator David Carlucci said, “The bike/pedestrian path has the potential to become a major attraction and economic engine for Rockland County. Putting the parking at interchange 10 makes sense for the village and the state. I applaud Governor Cuomo and the Village of South Nyack for working together with the residents of our community to make this happen.”

Assemblywoman Ellen Jaffee said, “We greatly appreciate the hard work and dedication of Mayor Christian, the South Nyack Tappan Zee Task Force and the Governor’s team. The cooperation and determination of all the parties involved to come together is a testament to the leadership on both the state and local levels.”

Rockland County Legislator Nancy Low-Hogan said, “I want to thank the Governor and his team for listening to the people of this community, and also thank Mayor Christian, the South Nyack Task Force and Village Board. I commend the citizens of South Nyack for their willingness to articulate their concerns and work together to solve this problem in a constructive way.”

Town of Orangetown Supervisor Andy Stewart added, “Ending the shared use path at Interchange 10 makes sense, especially as it begins the redevelopment of this interchange to better serve South Nyack and its visitors. This is a good thing and the Governor, the Mayor and the local taskforce members are to be congratulated for their collaboration.”

The Thruway Authority and Federal Highway Administration are undertaking an Environmental Assessment to study various parking options for the path. Formal public hearings will be held as part of the process once a draft Environmental Assessment is complete.

WORK CONTINUES ON TEMPORARY ALL-ELECTRONIC TOLL COLLECTION SYSTEM

update
Several Weeks of Weekday Overnight Triple-Lane Closures
on New York State Thruway (I-87/I-287) Start May 4

Several weeks of weekday overnight triple-lane closures of southbound New York State Thruway (I-87/ I-287) will begin Monday, May 4. The Monday-through-Friday closures will start as early as 7 p.m. with the closure of one lane near exit 11 (Nyack – South Nyack – US Route 9W) to the Tappan Zee Bridge, followed by a second lane closed at 9 p.m. and a third at 10:30 p.m. All lanes will reopen 6 a.m., Tuesday through Friday and 8 a.m., Saturday. At least one lane will remain open at all times, except during the periodic traffic holds described below.

The lane closures are necessary to allow Tappan Zee Constructors, LLC (TZC) to modify the highway for a temporary all-electronic toll collection system that will be employed until a permanent system is constructed in the location of the current toll plaza in Tarrytown.

In addition, periodic closures of all four lanes of the southbound Thruway in the vicinity of exit 11 (Nyack – South Nyack – US Route 9W) will occur between 8 p.m. and 4 a.m. during the overnights of Wednesday, May 6 and Thursday, May 7. To ensure the public’s safety, the New York State Police will stop and hold all traffic approaching the area immediately before the closures go into effect. Motorists will be permitted to enter the Thruway from all ramps during the closures. The complete closures are necessary to move equipment from the right shoulder to the left shoulder.

Finally, the exit 10 (Nyack – South Nyack – US Route 9W) on-ramp to the southbound Thruway will be closed from 10 p.m., Tuesday, May 5 to 5 a.m., Wednesday, May 6. Drivers will be directed to use the on-ramp from Route 59 in Nyack, as shown on the following graphic. The closure will allow TZC to mobilize a crane that will place concrete slabs for the all-electronic toll collection system.

All planned work is subject to postponement due to weather conditions.

River Road in South Nyack
River Road utility work will continue the week of May 4. The work may require reducing River Road to one lane at times. TZC flag persons will direct traffic as needed and additional signage as well as other safety measures will be in place.

Foundation Work on the New Bridge
Marine crews will continue working on the foundations for the new bridge next week by placing reinforcing steel and concrete in the piles, main span pile caps and approach span pile caps. The high-strength concrete is made on site by the project’s two floating batch plants. Teams also will erect formwork for the cast-in-place pier columns, which eventually will support the new bridge’s road deck. With only a small percentage of piles left to install, pile driving operations will continue next week. Pile driving is restricted to 7 a.m. to 7 p.m., Monday through Friday and noon to 7 p.m., Saturday.

Crews also will continue working on the bridge’s landings at the Rockland and Westchester shorelines. The abutments, comprised of steel and concrete, will serve as strong bases where the new crossing meets the landside roadway.

TZC will continue concrete placement for foundations near the South Nyack shoreline. The concrete for this work is being acquired from local concrete suppliers and is delivered by truck to the Rockland trestle located off the Thruway’s southbound access ramp. Trucks exit the trestle to the Thruway via the northbound access ramp. The access ramps are used only by construction vehicles, providing a safe route directly to the work site and reducing traffic impacts on local roads.

Additional work includes:

  • Pile cap foundation construction
  • Main span foundation construction
  • Concrete placement for foundations
  • Landing abutment concrete work
  • River Road utility work
  • Support for river-based work from the Rockland trestle
  • Survey inspections on the existing bridge

Boater Safety
The U.S. Coast Guard has established a Safety Zone surrounding 16 construction barge mooring locations at the project site. No unauthorized vessels are allowed in the Safety Zone. In addition, marine law enforcement will be enforcing the rules of the expanded Regulated Navigation Areas (RNAs) east and west of the Safety Zone. The RNAs stretch 500 yards north and 500 yards south of the existing bridge. Boaters are urged to transit the main channel with no wake at a maximum speed of 5 knots and to use extreme caution on the river at all times.

More New NY Bridge boater safety information, including the U.S. Coast Guard Notice to Mariners and construction site maps, can be found here at NewNYBridge.com. An interactive map showing vessel locations on the Hudson River is also available here for recreational and commercial boaters to get updated information on the very active construction zone. The GPS tracking map is for informational purposes and not intended for navigation.

Mariners also should be aware that TZC will continue work in the vicinity of the side channels under the existing bridge. Additional temporary navigational lights have been installed to further define the 600-foot navigation channel under the main span. Permanent elements of the new bridge are lit per U.S. Coast Guard requirements, as are all moorings, barges and other equipment.

All lane closures are subject to change due to traffic, weather or emergency situations. Please visit http://www.thruway.ny.gov/travelers/map/ for real-time information regarding traffic conditions.

SUPER CRANE SUCCESSFULLY COMPLETES FIRST LIFT ON

update

NEW NY BRIDGE PROJECT
I LIFT NY hoists massive 600-ton foundation element into place today

One of the world’s largest floating cranes this morning successfully completed the first of many enormous lifts for the New NY Bridge project, following months of planning and preparation.

In a carefully coordinated three-and-a-half hour operation on the Hudson River between Westchester and Rockland counties, the I Lift NY super crane hoisted and set one of the project’s largest precast concrete pile caps weighing in at 600 tons.

Video and photos from today’s lift will be posted here.

“We brought in the I Lift NY super crane to reduce construction time and cost, and this first lift is another symbol that the New NY Bridge is officially on the way,” Thruway Acting Executive Director Robert L. Megna. “The crane is a key tool to building the bridge in a safer, more cost-effective, environmentally-friendly way. With savings of more than a billion dollars for tollpayers, this super crane will continue to do great work.”

Owned by Tappan Zee Constructors, LLC, the design-build contractor for the New York State Thruway Authority, the super crane’s extraordinary capabilities save time and money while enhancing quality and safety by allowing large sections of the bridge to be pre-fabricated off-site and shipped by barge to the construction zone.

I Lift NY will continue to lift and place sections of the new twin-span bridge — some weighing from 900 to 1,100 tons — and will assist with the dismantling of the existing 60-year-old Tappan Zee Bridge, reducing costs and shortening the deconstruction process.

The super crane’s boom is 328 feet tall, which is taller than a 30-story building, and can lift up to 1,900 tons, or the equivalent of 12 Statues of Liberty, at once. Despite its enormity, the barge-mounted crane sits high in the water, thereby reducing the need for dredging on the project by 50 percent.

The I Lift NY super crane made a 6,000-mile journey from the San Francisco Bay area in 2014, passing through the Panama Canal.

Since its arrival here in New York, the crane has gone through months of testing, modifications and upgrades including a new high-tech computer operating system and complete replacement of its rigging cables. The most experienced operating engineers in the area also spent months of specialized training to carefully handle this massive machine. Now that the ice has cleared on the Hudson River, the I Lift NY crane is getting to work on the pile caps and later this year will begin placing the even heavier structural steel beams that will carry the road deck across the new spans.

New NY Bridge Progress
Under Governor Cuomo’s leadership and with the support of President Barack Obama and the Federal government, the New NY Bridge project has progressed dramatically since construction began in October 2013 following many years of delay. Since October 2011, steps forward include: enactment of new design-build legislation; review and completion of concurrent environmental review and procurement processes; negotiation of a project labor agreement with construction unions; and recommendation from a panel of local leaders and transportation experts for a comprehensive plan for mass transit options for the region – all with an unprecedented level of transparency and community involvement.

About the New NY Bridge
The New NY Bridge’s eight traffic lanes, four breakdown and emergency lanes, and state-of-the-art traffic monitoring systems will mean less congestion for motorists. Designed and constructed to be mass-transit-ready, the new crossing will be able to accommodate bus rapid transit, as well as light rail or commuter rail. The bridge will also include a bike and pedestrian shared-use path. Extensive measures are in place throughout the duration of the project to protect the environment and to monitor the impact of construction on surrounding communities.

Traffic Update thru Jan 4th to Ease Holiday Travels

For immediate release: December 26, 2014

ALL LANES OF NEW YORK STATE THRUWAY (I-87/I-287) WILL REMAIN OPEN FROM FRIDAY DEC. 26, 2014 THROUGH SUNDAY, JAN. 4, 2015 TO EASE HOLIDAY TRAVEL

All lanes of the New York State Thruway (I-87/I-287) will remain open from Friday, Dec. 26, 2014 through Sunday, Jan. 4, 2015 to help New Yorkers reach their winter holiday destinations. The 10-day lane-closure-free period follows Governor Andrew M. Cuomo’s “Drivers First” initiative, which gives priority to motorists by ensuring that disruptions associated with highway and bridge projects are kept as minimal as possible.

While Tappan Zee Constructors, LLC (TZC) will continue working in several areas of the project during the week of Dec. 29, none of the planned activities will result in the closure of any traffic lanes. No construction work is scheduled for New Year’s Day, Thursday, Jan. 1, 2015, though safety and security teams will remain on site.

Limited concrete placement will continue as TZC progresses the investigation of the recent incident on one of its floating concrete batch plants. The concrete for foundations near the S. Nyack shoreline will be acquired from local concrete suppliers that will be delivered to the site via trucks to the Rockland Trestle off of the New York State Thruway southbound access ramp. The trucks will exit the trestle to the Thruway via the northbound access ramp. This work could begin as soon as this week.

Activities on the Westchester and Rockland landings will continue as originally scheduled as this work has always been planned to receive the needed concrete from trucks to the site.

Continued Demolition of Westchester Landing of Existing Tappan Zee Bridge
Following the removal of sections of deck of the existing Tappan Zee Bridge to make way for the new bridge, the associated supporting piers are being demolished. The majority of this work, which will clear the path for the northbound bridge’s landing and first foundation pier, will be completed during daytime hours.

Pile Driving and Other Construction Activity
Construction will continue in the Hudson River as crews place the foundations of the new bridge. Work will include pile driving from 7 a.m. to 7 p.m., Monday through Wednesday and noon to 7 p.m., Saturday. No pile driving will occur on New Year’s Day, Thursday, Jan. 1, 2015. Operations will resume on Friday, Jan. 2, 2015 at 7 a.m.

A second shift of workers also will continue pile welding, pile cleanout and concrete placement operations associated with foundations.

Work is continuing on the new bridge’s landings on both sides of the river.

Additional work includes:

  • Pile cap foundation construction
  • Main span foundation construction
  • River Road utility work
  • Support for river-based work from the Rockland trestle
  • Survey inspections on existing bridge

Tappan Zee Bridge Skeleton Takes Shape at Tomkins Cove

Khurram Saeed and Theresa Juva-Brown, tjuva@lohud.com9:11 a.m. EDT October 22, 2014

Less than 15 miles from where the new Tappan Zee Bridge is being built, its steely skeleton is being put together. Dozens of workers are assembling fortified steel cages along the Hudson River.

Less than 15 miles from the Tappan Zee Bridge, the steel skeleton of its replacement is being meticulously pieced together.

“The site is perfect,” Ro DiNardo, construction services manager for bridge builder Tappan Zee Constructors, said. “It’s 18 acres, and it has all the space we needed for these activities.”

For the first time, Tappan Zee Constructors on Tuesday offered a behind-the-scenes look at the bustling staging area at Tomkins Cove, a former power plant next to the Hudson River. DiNardo said its proximity to the bridge is saving time on the $3.9 billion replacement project, which is expected to be completed in 2018.

Here’s a breakdown of what’s happening on site:

Pile reinforcement

The estimated 1,000 hollow piles that are being set in the Hudson River are being fortified with cages made of reinforced steel, also known as rebar.

Bridge columns

Workers are also assembling cages that will ultimately become bridge columns. The steel structures are produced in a factory in New Jersey and dipped in hot zinc to strengthen them. The coiled-up steel is loaded on trucks and delivered to Tomkins Cove.

Using detailed diagrams, crews of five workers spend several days creating the sections, some of which are 20 feet long.

Then, DiNardo said, comes the tricky and most dangerous part: pouring the concrete into the mold that is built around sections of steel.

“We actually have to put men inside there so we can pour from the bottom and work our way up,” said DiNardo, of New City. “There are a lot of safety concerns. We have to have an entire plan together before we put anyone in there.”

Tower work

The structures that will be used to build the bridge’s eight towers are under construction at the site, too.

Each rectangular platform, known as climbing forms, has an opening in the middle where the concrete gets poured to create the towers in sections.

A hydraulic lift will raise the structure, with the platform eventually standing more than 30 stories above water.

“As we build, this will move with us,” DiNardo said of the platform.

The climbing forms are expected to arrive at the project site by barge in February.

Improved safety

Because the staging area sits next to an active railroad, the project team and railroad officials have had to make adjustments.

In the past few months, CSX freight trains were left unattended for up to two hours during crew shift changes, blocking emergency access to the site. In one instance over the summer, a worker who had an allergic reaction to something he ate, had to be brought by boat to a medical facility in Westchester.

Tappan Zee Constructors has just finished building a foot bridge over the tracks to allow emergency responders to reach the site by land.

The bridge builder expects to use Tomkins Cove through 2017. Eventually, the site will likely be used to demobilize cranes and other equipment when the work is done.

 

Fast facts

Tomkins Cove staging area: 18 acres

Workers: Approximately 60 not including subcontractors

Truck traffic: 5 to 20 per day

Barge traffic: 1 to 5 per day

Bridge Updates and Closings

update

NEW YORK STATE THRUWAY (I-87/I-287) southbound EXIT 9 TO BE CLOSED OVERNIGHT WEDNESDAY AND THURSDAY FOR PAVING OPERATIONS

Exit 9 (Tarrytown – Sleepy Hollow – US Route 9) of the southbound New York State Thruway (I-87/I-287) will be closed between 10 p.m. and 5 a.m. during the overnights of Wednesday, Oct. 22 and Thursday, Oct. 23 to enable a widening of the southbound New York State Thruway (I-87/I-287) in Westchester County.

The widening of the southbound Thruway will require paving the shoulder in the vicinity of Exit 9 and is being done to facilitate a series of lane shifts occurring in the near future. Drivers bound for destinations in the Tarrytown vicinity are advised to use Exit 8A (I-87 – Elmsford – NY Route 119), continue north on northbound Route 119/White Plains Road, turn right onto to I–287 west towards I-87/Tappan Zee Bridge and continue to Exit 9 (Tarrytown – Sleepy Hollow – US Route 9). Drivers bound for destinations on or near White Plains Rd/Route 119 are advised to use Exit 8A to stay on Route 119. See graphic below.

One lane of the northbound Thruway in the vicinity of Exit 9 will be closed at 8 p.m., Friday, Oct. 24. At 9 p.m., a second lane will be closed and at 10 p.m., a third lane will be closed. All lanes will reopen at 8 a.m., Saturday, Oct. 24. These closures also are related to the above-mentioned paving operation.

Motorists are reminded that the northbound Thruway lanes recently were narrowed slightly at the Westchester approach to the Tappan Zee Bridge and the speed limit was reduced to 45 mph.

Construction will continue in the Hudson River as crews place the foundation for the new bridge. Work will include pile driving between 7 a.m. and 7 p.m., Monday through Friday and noon to 7 p.m., Saturday.

A second shift of workers also will continue pile welding, pile cleanout and concrete placement operations associated with permanent foundations.

Tappan Zee Constructors, LLC, (TZC) is continuing construction of the new bridge’s landings.  In Westchester, work includes drilling holes into the bedrock for the foundation of the landing. In Rockland, a similar operation is improving the strength of the soil by using aggregate piers, which are made by using a drill to mix soil and aggregate (i.e., crushed stone) to form a strong base for the new bridge’s abutment and foundation. The drilling process is less audible than impact pile driving and TZC has implemented noise-reducing measures to further minimize sound levels. The eight-week operation is anticipated to conclude in November.

Work will continue on the Rockland work trestle near the shoreline, including pile driving and cofferdam installation. The trestle will support equipment used for the construction of the westernmost section of the new bridge.

The U.S. Coast Guard has established a Safety Zone surrounding 16 construction barge mooring locations at the project site. No unauthorized vessels are allowed in the Safety Zone. In addition, marine law enforcement will be enforcing the rules of the expanded Regulated Navigation Areas (RNAs) east and west of the Safety Zone. The RNAs stretch 500 yards north and 500 yards south of the existing bridge. Boaters are urged to transit the main channel with no wake at a maximum speed of 5 knots, and to use extreme caution on the river at all times.

Building the Backbone of the New NY Bridge


Main Span Bases Rise out of the Hudson

August 7, 2014

Two enormous structures with bases the size of football fields are rising out of the Hudson River at the New NY Bridge project site. These concrete monoliths are the pile caps that will act as the structural backbone for New York’s largest bridge and highway infrastructure project, distributing the weight of the bridge onto dozens of steel foundation piles.

The main span pile caps will support the bridge’s 400-foot towers, and require months of preparation to complete.

To construct these main span pile caps, steel pilings are first driven deep into the riverbed, reaching bedrock hundreds of feet below the surface. Once all the piles are in place, a series of concrete floor panels is pieced together around them, outlining the footprint of the pile cap as the supporting base for its concrete pour. The team then positions heavy steel panels precisely around the edge of this footprint to form a massive tub, which is sealed to be watertight and carefully lowered into the river to bring its base to the proper final level for the concrete pile cap.

Next, workers build the pile cap’s reinforcement system inside this lowered tub. The team installs high-strength steel reinforcement bars, called rebar, to closely-engineered dimensions within the form.

The project’s floating batch plantsare then moved adjacent to the pile cap, and each form is filled with concrete specially formulated for long-term durability. The process continues over many hours until the entire footprint is covered with concrete to the specified depth. Once this steel-reinforced concrete hardens, the backbone of the new structure will have taken shape.

Learn more about how steel piles are transported to the project site, or installed with the well-being of local wildlife in mind.

CREWS MOBILIZE FOLLOWING WINTER WEATHER SHUTDOWN; PILE DRIVING RESUMES ON NEW NY BRIDGE PROJECT

new

Project Update

For immediate release: February 21, 2014

Tappan Zee Constructors, LLC (TZC) resumed marine operations and pile driving this week as icy conditions cleared in the Hudson River and crews could safely go back to work. Pile driving operations will continue next week and a second shift of workers will be onsite to resume welding on the piles that will become the permanent foundation for the New NY Bridge.

Pile driving will take place between 7 a.m. and 7 p.m. on weekdays, and occasionally between noon and 7 p.m. on Saturdays.

Beginning the week of Feb. 24, crews will conduct nighttime geotechnical investigations on the Westchester approach to the existing bridge, in the vicinity of the toll plaza. Lane closures to support these operations will be in place from 8 p.m. to 5 a.m., as needed, to minimize disruptions to traffic. This geotechnical investigation will confirm the soil conditions and ultimately allow the team to further streamline the design of the Westchester landings.

Lane Closures for New York State Thruway (I-87/I-287):

Monday Feb. 24 Southbound, Right Lane Near Toll Plaza 8 p.m. to 5 a.m.
Tuesday Feb. 25 Southbound, Right Lane Near Toll Plaza 8  p.m. to 5 a.m.
Wednesday Feb. 26 Southbound, Right Lane Near Toll Plaza 8  p.m. to 5 a.m.
Thursday Feb. 27 Northbound, Right Lane Near Toll Plaza 8  p.m. to 5 a.m.
Friday Feb. 28 Northbound, Right Lane Near Toll Plaza 8  p.m. to 5 a.m.

Mariners should be aware that TZC will continue installing permanent piles in the vicinity of the side channels under the existing bridge, weather permitting. New temporary navigational lights have been installed to further define the 600-foot navigation channel under the main span. Both temporary and permanent piles are illuminated at night.

The U.S. Coast Guard has issued a revised Notice to Mariners with updated safety information, including the establishment of a Regulated Navigation Area (RNA) – 300 yards north and 200 yards south of the existing Tappan Zee Bridge. The U.S. Army Corps of Engineers has issued a modified permit for additional temporary mooring locations during construction of the new bridge. All boaters are advised to use the main channel, reduce wake and use extreme caution while transiting the area. If necessary, the Coast Guard may temporarily prohibit all vessel traffic in the RNA for safety purposes. The Coast Guard boating safety information and the modified mooring permit map can be found on the project website at NewNYBridge.com under the “Boater Safety” icon.

Ongoing Operations:
• Permanent pile installation, including pile driving between 7 a.m. and 7 p.m. on weekdays, and occasionally between noon and 7 p.m. on Saturdays
• Rockland access ramp modifications
• River Road utility work
• Test pile program
• Permanent pile installation
• Temporary Rockland trestle construction, including pile driving on weekdays 7 a.m. to 7 p.m.

Feds Will Loan Up to $1.6 Billion for TZ Bridge Construction

A Big Loan  for a Big Project

The U.S. Department of Transportation has approved a loan of up to $1.6 billion through its Transportation Infrastructure Finance and Innovation Act (TIFIA) program for construction of a new Tappan Zee Bridge.

The loan is the largest ever in the history of the TIFIA program.

The Secretary’s approval comes after the DOT’s Credit Council met this morning to review the loan application, said Congresswoman Nita Lowey (D, Westchester-Rockland).

Yesterday, Lowey wrote a letter urging the DOT to expedite consideration of the TIFIA application. It can be viewed here.

“This is a huge milestone for the construction of a New Tappan Zee Bridge, a critical link in our region’s infrastructure system and lifeline for commuters and businesses,” she said in a statement. “I am excited that the DOT has approved the largest ever TIFIA loan for a transportation project and that the work on a new bridge can continue to move forward.”

Actual construction started last week. Patch has that and all the TZB news on our dedicated page.

Gov. Andrew Cuomo said, “”Approval of New York State’s request for this loan is great news for the tens of thousands of commuters who depend on the Tappan Zee every day, for communities in the Lower Hudson Valley, and for our entire state.

“This is a huge win for New York State, creating thousands of jobs, and an endorsement of one of the most ambitious infrastructure projects in our history. It shows that despite over a decade of delay, New York can continue to build big,” Cuomo said.

Plans for a new bridge to replace the Tappan Zee were first discussed in 1999, and over the next 11 years, $88 million in taxpayer dollars was spent, 430 meetings were held, 150 concepts were considered, according to the governor’s office.

State Assemblyman David Buchwald said, “Today’s announcement is a victory for all New Yorkers. It reaffirms our progress on building the new Tappan Zee Bridge that is essential for our region’s economic vitality. I applaud Governor Cuomo for his leadership through each phase of this important project.”

Harriet Cornell, Chairwoman of the Rockland County Legislature, said the new bridge would be an important addition to the nation’s transportation network.

“Governor Cuomo has made this project a signature issue, and the federal government recognized its significance by granting the largest TIFIA loan in history,” Cornell said. “This bridge will provide economic development, thousands of jobs during construction, access to the entire Northeast and will be a magnificent sight spanning the Hudson River. This is wonderful news.”

Westchester County Executive Rob Astorino also congratulated the governor; but, he pointed out there are still financial issues to be dealt with.

“I congratulate Governor Cuomo on this good news. The next step is how do we finance the rest of the bridge and the mass transit improvements to and from the bridge, while keeping tolls as low as possible,” Astorino said. “The governor has my full support to help the state come up with the best financing plans possible.”

The new NY bridge

For Immediate Release: May 31, 2013

Pre-Construction Activities Continue on the New NY Bridge Project

No new pre-construction activities are slated for the week of June 3, 2013. Environmental monitors continue to be installed in Rockland County as the New York State Thruway Authority (NYSTA) and Tappan Zee Constructors, LLC finalize specific installation locations. The monitors continually record noise, vibration and air quality for the duration of the project. All readings can be viewed at www.NewNYbridge.com.

Test boring operations in the Hudson River continue as does work on the temporary Westchester trestle. The trestle is a work platform that will support a crane for the construction of the new bridge. The 1,000-foot long platform reduces the amount of dredging required and allows crews to work from the water and not from the Westchester shoreline. Work on the Westchester trestle will include daytime pile driving to install the temporary foundation piles needed to support the platform. Pile driving will be limited to the hours between 7 a.m. and 7 p.m. Monday through Friday.

Westchester:
Surveying, utility exploration and test boring work continues for the New NY Bridge Project during the week of June 3, 2013.
