Tappan Zee Constructors, LLC (TZC) recently installed the 650th concrete road deck panel for the westbound span. TZC began placing the panels in early October and is on track to install an additional 6,000 panels by year’s end. The work is occurring on top of recently-installed steel-blue girders, which continue to advance across the Hudson River.

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.

|
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.

EXIT 10 ON-RAMP TO SOUTHBOUND NEW YORK STATE THRUWAY (I-87/I-287) CLOSED TONIGHT, FRIDAY, MAY 29
Triple-Lane Closures, Periodic Traffic Stops of Southbound Thruway in South Nyack During Overnights the Week of June 1
The exit 10 (Nyack South Nyack US Route 9W) on-ramp to the southbound New York State Thruway (I-87/I-287) will be closed from 9 p.m., Friday, May 29 to 5 a.m., Saturday, May 30. Drivers will be directed to use the on-ramp from Route 59 in Nyack, as shown in the following graphic. The closure will allow Tappan Zee Constructors, LLC (TZC) to safely move equipment needed to place concrete slabs for a new 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.
Additionally, weekday overnight triple-lane closures of the southbound Thruway will occur from Monday night, June 1 through Saturday morning, June 6. Closures will start at 7 p.m. with the closing of one lane near exit 11 (Nyack – South Nyack – US Route 9W) to the Tappan Zee Bridge, followed by a second lane at 9 p.m. and a third at 10:30 p.m. All lanes will reopen by 6 a.m. the following weekday or 8 a.m. the following Saturday.
Additionally, a double-lane closure is planned for the overnight of Saturday, May 30, with a single lane closing at 7 p.m., followed by a second lane at 11 p.m. The lanes will reopen by 10 a.m., Sunday, May 31.
The lane closures are necessary to allow TZC to modify the highway for the temporary all-electronic toll collection system.
During the weekday and weekend overnight closures, at least one lane will remain open at all times, except during periodic traffic stops lasting up to 10 minutes of all four lanes of the southbound Thruway near exit 11 (Nyack South Nyack US Route 9W), which will occur between 8 p.m. and 5 a.m. during the overnights of Thursday, June 4 and Friday, June 5. To ensure the publics safety, the New York State Police will stop and hold all traffic approaching the area immediately before the traffic stops go into effect. Motorists will be permitted to enter the Thruway from all ramps during the traffic stops. The complete traffic stops are necessary to move equipment from the right shoulder to the left shoulder.
All planned work is subject to postponement due to weather conditions.
River Road in South Nyack
River Road utility work will continue during the week of June 1. 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 projects floating batch plants. Teams also will erect formwork for the cast-in-place pier columns, which eventually will support the new bridges road deck.
While the current phase of pile driving is anticipated to end soon, pile driving 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 bridges 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.
Construction of pier 1 located near River Road in South Nyack will continue with the installation of sheet piles. The sheet piles support the surrounding soil while the foundation for the new bridge pier is constructed. TZC is implementing noise-reducing measures, including sound-absorptive temporary noise barriers, to protect nearby residents. The projects environmental compliance team will be on site to monitor noise levels during the operation.
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 Thruways 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:
Boater Safety
During the summer months, Westchester and Rockland Marine Units will add extra overnight 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.
Members of the New NY Bridge project team will preview upcoming construction activities, discuss the progress thus far, and unveil some new design features at this year’s annual meeting for Rockland County.
Also, there will be a Q&A session with the audience and project leaders from the New York State Thruway Authority and Tappan Zee Constructors.
The annual meeting will be moderated by Brian Conybeare, the project’s special advisor.
WHEN: 6:30-8PM May 14
WHERE: Nyack High School, 360 Christian Herald Road, Nyack.
The Westchester annual meeting is Tuesday at Washington Irving School in Tarrytown.

For immediate release: December 19, 2014
ALL LANES OF NEW YORK STATE THRUWAY (I-87/I-287) WILL REMAIN OPEN FROM WEDNESDAY, DEC. 24 THROUGH SUNDAY, DEC. 28 TO EASE HOLIDAY TRAVEL
All lanes of the New York State Thruway (I-87/I-287) will remain open from Wednesday, Dec. 24 through Sunday, Dec. 28 to help New Yorkers reach their winter holiday destinations. The five-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. 22, none of the planned activities will result in the closure of any traffic lanes. No construction work is scheduled for Christmas Day, Thursday, Dec. 25, though safety and security teams will remain on site.
20-Minute closures of the north- and southbound Thruway and other lane closures scheduled for overnight Friday, Dec. 19
The removal of an overhead sign gantry near exit 10 in South Nyack will require the closure of three lanes of the southbound New York State Thruway (I-87/I-287) during the overnight of Friday, Dec. 19. Two lanes will be closed at 9 p.m., followed by a third lane at 12 midnight. One lane will remain open, other than during the periodic complete closures detailed below. The three closed lanes will reopen at 7 a.m., Saturday, Dec. 20.
The operation also will require a series of 20-minute closures of all four lanes on both the north- and southbound Thruway between the hours of 11:59 p.m., Friday, December 19 and 6 a.m., Saturday, December 20. To ensure the safety of the public, the New York State Police will stop and hold all traffic approaching the gantry removal operation immediately before the closures go into effect. Motorists will be permitted to enter the Thruway from all ramps during the closures.
Travelers are advised that delays are likely on both directions of the Thruway during the overnight operation.
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 Christmas Day, Thursday, Dec. 25 or Friday Dec. 26.
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:

STONY POINT – 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

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 I287 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.

Posted Oct. 6, 2014 @ 7:33 pm
NYACK – One of the world’s largest floating cranes, in the wings in Jersey City since January, finally took center stage at the construction site of the new Tappan Zee Bridge on Monday. The crane, known as the I Lift NY, got the kind of gushing welcome that celebrities are accustomed to – including a declaration of love from Gov. Andrew Cuomo.
“I truly love this crane,’’ said Cuomo, surrounded by dozens of crane-ogling journalists and officials on a 149-passenger ferry off Piermont. “Every New Yorker should love this crane because it’s saving us a lot of money – as much as a billion dollars.”
The crane was a factor in the ability of Tappan Zee Constructors to win the $3.1 billion contract to design and build the new TZB, underbidding its two competitors by almost $1 billion in the process. Its superior lifting ability will allow much of the new bridge’s superstructure to be assembled off site and hoisted into place, slicing time and expense off the construction bill.
Darrell Waters, TZC’s president, said the crane will start work this week, and construction, concentrated in the river until now, will become more vertical and visible by the end of the year.
“We are 24 percent complete and we are on time and on budget,’’ said Waters, adding that 65 percent of the piles that will ultimately support the new bridge’s piers have been installed.
What surprised the welcoming party on the ferry was how ordinary the partially collapsed crane looked as it glided toward the TZB at four knots – despite sitting on a barge the size of a football field.
Its jaw-dropping size only became apparent when the ferry swung around it and the crane could be viewed against the bridge – and then it towered over the bridge and the 130 other pieces of construction equipment, including 31 cranes, in the water.
TZC will fill the barge with water and further collapse portions of the crane Tuesday in preparation for moving the I Lift NY beneath the bridge, 139 feet above the Hudson at low tide, Wednesday. Waters said he expects to have three feet of clearance.
As the ferry returned to Piermont, Cuomo was peppered with questions about what the tolls will be when the new bridge opens in 2018, a subject he has avoided in this election year.
The governor said that the state needs “a little more information” before it can speculate about the tolls. He pointed out incentives and penalties in the construction contract, as well as additional state or federal aid, could ultimately affect the project’s cost and the amount to be raised through tolls.
“It’s four years down the road,’’ he said.

The Hudson Valley is a unique geological formation, created by receding glaciers tens of thousands of years ago. As the colossal sheets of ice melted and formed the Great Lakes, the melt-water rushed down the Palisades and filled the Hudson Valley with enough sediment to bury the Statue of Liberty. This torrential force of nature created the striking Hudson Valley landscape and more recently, a number of geotechnical hurdles for the New NY Bridge project. |

CONSTRUCTION CONTINUES ON THE NEW NY BRIDGE
Tappan Zee Constructors, LLC (TZC) will continue work on the Rockland County landing of the new bridge. The work will last several weeks and includes the installation of sheet piles, some measuring over 50 feet long. These interlocking steel sheets will support the existing roadway during the excavation and construction process. A large crane with a vibratory pile hammer will install the sheets, and be positioned behind a temporary concrete barrier in South Nyack.
In Westchester County, crews will conduct directional boring for future utility relocations under I-87/I-287 west of the toll plazas from 9 p.m. to 4:30 a.m. the week of June 23. The overnight operation requires the closing of various toll lanes. Different tolls lanes will be affected as the work progresses. The Thruway will remain open at all times.
Construction of the New NY Bridge will continue with pile driving between 7 a.m. and 7 p.m., Monday through Friday and 12 noon to 7 p.m. on Saturday.
A second shift of workers will also continue pile welding operations associated with permanent foundations.
Work will also continue on the Rockland temporary work trestle near the county shorelines, including pile driving to install the temporary foundations needed to support the platform. The trestles will support cranes for the construction of the western-most section of the new bridge.

A short reprieve from bad weather in the last week has finally allowed Tappan Zee Bridge construction crews to resume work on the Hudson River.
Not only are they back to work, but crews are toiling away around the clock to install giant steel piles that will help support the new crossing. The pile
s are being installed in two segments and then welded together.
The pile welders, members of the local dockbuilders union, are working six days a week in two 12-hour shifts. As the work progresses, a third shift will be added, with each team of welders working eight-hour shifts six days a week, project leaders say.
Over the next year, leaders have said they hope to have 1,000 piles installed in the river. Crews are currently working on a batch of 90 piles.
In other Tappan Zee Bridge project news this week:
• The project’s 31-member mass transit task force delivered its final report on Friday, after more than a year of meetings. The Thruway Authority formed the panel in 2012 to study and make recommendations for mass transit improvements on Interstate 287.
• The panel has proposed expanding the existing Tappan ZEExpress bus service and a creating a “bus rapid transit” system with seven routes in Westchester and Rockland. The ambitious plan calls for a series of new stations, modern vehicles, and dedicated bus lanes in some places.
• The report did not include cost estimates or specific ways to pay for such a system. Still, top state transportation leaders said they are committed to having the system in place by the time the new Tappan Zee is completed in 2018.

UTILITY WORK BEGINS ON RIVER ROAD
Tappan Zee Constructors, LLC will begin utility work on River Road in South Nyack the week of Sept. 9. This work will continue through November and will involve reducing the roadway to one lane during daytime hours. During off hours the road will have temporary coverings in place that may create uneven driving surfaces. Motorists and bicyclists should slow down and use caution in the area.
Construction of the Rockland County trestle will continue and include daytime pile driving to install the temporary foundation piles needed to support the platform. Pile driving will be limited to a maximum of 7 a.m. to 7 p.m. on weekdays and, occasionally, from 12 noon to 7 p.m. on Saturdays. The trestle is a work platform that will support a crane for the construction of the westernmost section of the new bridge. The 1200-foot long platform helps reduce the amount of dredging required.
Impact pile driving will continue as part of the ongoing test pile program and will continue through October at various locations for future pile foundations during the same timeframe as above. The test pile program will verify subsurface conditions and test structural load capacities in preparation for construction of the new bridge’s permanent foundation.
The U.S. Coast Guard has issued a revised Notice to Mariners with updated safety information, including a request that boaters use the main channel, reduce wake and use extreme caution while transiting the area in the vicinity of the Tappan Zee Bridge.

NO IMPACT PILE DRIVING OR LANE CLOSURES SCHEDULED FOR LABOR DAY HOLIDAY WEEKEND, ROCKLAND BULKHEAD CONCRETE PLACEMENT TO COMMENCE
Tappan Zee Constructors, LLC (TZC) will not engage in any pre-construction activities that affect traffic through Monday, Sept. 2 in observance of Labor Day. No lane closures will be allowed until Tuesday Sept. 3 at 10am in order to avoid impacts on motorists during the busy Labor Day holiday travel weekend. In addition, no impact pile driving is scheduled until Tuesday September 3.
Dredging will continue 24/7 through Oct. 31. As outlined in the Final Environmental Impact Statement for the New NY Bridge project, the dredging window is designed to avoid negatively impacting migration and spawning patterns of local sturgeon populations and other fish species. The operations will deepen the river’s shallow water level in the work zone by removing sediment from the river bottom. The dredged materials are being properly disposed of at offsite locations.
Rockland bulkhead construction continues next week with concrete placement. Frequent concrete truck traffic is expected on certain designated roads in the villages of Nyack and South Nyack from 9 a.m. to 4 p.m. on Tuesday, Wednesday and possibly Thursday. TZC and the Thruway Authority have coordinated extensively with village leaders and local police to ensure safety and minimize impacts on traffic, the villages and their residents. Anyone with questions can call the New NY Bridge 24-hour Toll-Free Hotline: 1-855-TZ-BRIDGE.
