For immediate release: Dec. 22, 2015

ALL LANES OF NEW YORK STATE THRUWAY (I-87/I-287) WILL REMAIN OPEN FROM THURSDAY, DEC. 24 THROUGH SUNDAY, DEC. 27 TO EASE HOLIDAY TRAVEL

All lanes of the New York State Thruway (I-87/I-287) will remain open from Thursday, Dec. 24 through Sunday, Dec. 27 to help New Yorkers reach their winter holiday destinations. The four-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 work will impede traffic. No construction work is scheduled for Christmas Day, Friday, Dec. 25. Safety and security teams will remain on site throughout the holiday period.

All-Electronic Toll Collection Gantry Work
Construction of the project’s temporary all-electronic toll collection (AETC) system in Rockland will continue this week near the exit 10 (Nyack – South Nyack – US Route 9W) on-ramp to the southbound Thruway. The work will require overnight closures of two lanes of the southbound Thruway on Tuesday, Dec. 22 and Wednesday, Dec. 23. Specific lane closure times are detailed in the chart below.

Installation of Noise Barriers in South Nyack
Next week will see continued construction of foundations for noise barriers along the southbound Thruway between the South Broadway bridge and River Road. The construction 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:

  • Main span tower construction
  • Support for river-based work from the Rockland trestle
  • Rockland landing retaining walls
  • Survey inspections on the existing bridge
  • Westchester landings utility work
  • Girder assembly placement
  • Bridge road deck installation

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. 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, construction site maps, can be found here at NewNYBridge.com. 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.

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.

Tappan Zee Bridge Project Update

December 4, 2015 by

update

For immediate release: Dec. 3, 2015

INSTALLATION OF CONCRETE ROAD DECK CONTINUES
Overnight Closure of Southbound Exit 10 On-Ramp on Monday, Dec. 7

Tappan Zee Constructors, LLC (TZC) will begin installing bridge road deck segments near the Rockland shoreline on Thursday, Dec. 10. Project cranes will lift the prefabricated deck panels into place atop previously-installed structural steel girders.

Safely accomplishing the work will require reducing River Road/Piermont Avenue to one lane during weekdays starting on Thursday of next week. Flag persons will keep traffic moving by alternating the directional flow between north and south. TZC will also periodically hold traffic on River Road/Piermont Avenue for 6-minute intervals through Friday, Dec. 18 to enable the safe movement of deck panels and other materials.

Nearly 6,000 high-strength concrete deck panels will be installed for the new crossing’s approach spans. The panels 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 across the river over the coming year.

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 the southbound New York State Thruway (I-87/I-287). The work will necessitate closing the on-ramp during the overnight of Monday, Dec. 7. Drivers will be directed to use the on-ramp from Route 59 in Nyack, as shown in the graphic below. This and other work require the specific lane and ramp closures detailed in the chart below.

Steel Girder Installation
Next week, 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.

The remaining work over the Metro-North tracks will occur during a Friday overnight later this month, with the entire operation anticipated to conclude by the end of the year. 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.

The I Lift NY super crane will continue placing larger girder assemblies 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.

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.

Installation of Noise Barriers in South Nyack
Next week will see continued construction of foundations for noise barriers along the southbound Thruway between the South Broadway bridge and River Road. The construction 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
  • Rockland landing retaining walls
  • Survey inspections on the existing bridge
  • Westchester landings utility work

TZ Bridge Traffic Updates For the Week of June 15, 2015

June 15, 2015 by

update

For immediate release: June 12, 2015

CONSTRUCTION STARTING ON NOISE BARRIERS ALONG SOUTHBOUND NEW YORK STATE THRUWAY (I-87/I-287) IN SOUTH NYACK

After months of preparation, crews will begin installing foundations for noise barriers along the southbound New York State Thruway (I-87/I-287) 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.

Continued Overnight Triple-Lane Closures of Southbound Thruway
Weekday overnight triple-lane closures of the southbound Thruway will occur from Monday night, June 15 through Saturday morning, June 20. Closures will start at 8 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 11 p.m. All lanes will reopen by 6 a.m. the following weekday. The closures on Friday, June 19 will start with a single lane at 9 p.m., a second lane at 11 p.m. and a third at 11:59 p.m. All lanes will reopen by 8 a.m., Saturday, June 20.

Triple-lane closures of the southbound Thruway in the same area also are planned for the overnight of Saturday, June 13, with a single lane closing at 7 p.m., followed by a second lane at 11 p.m. and a third at 1 a.m., Sunday, June 14. All lanes will reopen by 11 a.m., Sunday, June 14.

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

Single-Lane Closures of Northbound Thruway During Morning Commuting Periods on June 18 and 19
Single-lane closures of the northbound Thruway will occur on Thursday, June 18 and Friday, June 19. The closures will start at 5 a.m. near the Tappan Zee Bridge to exit 11 (Nyack – South Nyack – US Route 9W). The lane will reopen by 2 p.m. both days.

River Road in South Nyack
River Road utility work will continue during the week of June 15. 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.

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. Pile driving is restricted to 7 a.m. to 7 p.m., Monday through Friday and noon to 7 p.m., Saturday. TZC is implementing noise-reducing measures, including sound-absorptive temporary noise barriers, to protect nearby residents. The project’s 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 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
  • Landing abutment concrete work
  • Support for river-based work from the Rockland trestle
  • Survey inspections on the existing bridge
  • Westchester Landings utility work

Boater Safety
During the summer months, Westchester and Rockland Marine Units will add extra 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.

TZ Bridge Project Update and Lane Closures for the Week of March 23, 2015

March 23, 2015 by

FLOATING BATCH PLANTS RETURN TO WORK ON THE NEW NY BRIDGE PROJECT
Triple-Lane Closure on Northbound New York State Thruway (I-87/I-287) During Overnight of Wednesday, Mar. 25

Tappan Zee Constructors, LLC’s (TZC) two floating concrete batch plants recently returned to the work site, passed the required testing and soon will begin pumping concrete. The batch plants were taken out of service in December after a silo failed.

The concrete plants move from location to location on the river, providing high-quality concrete where it is needed to build the New NY Bridge project. Their resumption of service will reduce the number of concrete trucks using local roads.

The following lane and exit closures are planned for next week:

Three left lanes of the northbound Thruway (I-87/I-287) will be closed from exit 9 (Tarrytown – Sleepy Hollow – NY Route 9) to exit 10 (Nyack – South Nyack – Route 9W), and including the Tappan Zee Bridge, from 9 p.m., Wednesday, Mar. 25 to 4:30 a.m., Thursday, Mar. 26. One lane will remain open during the closure. The closures are necessary to accommodate road-striping work.

Additionally, road striping will require the closure of the two left (35 mph) E-ZPass lanes at the southbound Thruway toll plaza in Tarrytown from 10 p.m. Friday, Mar. 27 to 5 a.m., Saturday, Mar. 28. The work also will necessitate the closure of the southbound exit 9 off-ramp to Route 9 from 10 p.m., Friday, Mar. 28 to 5 a.m., Saturday, Mar. 28. Traffic that would otherwise use exit 9 will be detoured to exit 8A, as shown below:

map

Turn-by-turn directions for southbound exit 9 closure detour:

  1. Exit onto the exit 8A off-ramp;
  2. At the end of the long ramp, turn right on westbound Route 119/White Plains Road;
  3. Enter westbound I-287, which merges with northbound I-87;
  4. Exit onto the exit 9 off-ramp;
  5. Turn left onto westbound Route 119/White Plains Road; and
  6. Turn left or right on Route 9, depending on your destination. 

Preparations for the Temporary All Electronic Toll Collection system in South Nyack near exit 10 will require a single right-lane closure from 10 a.m. to 3 p.m. on Monday, March 23 and Tuesday, March 24.

Marine operations continue to gear up following the winter shutdown, with crews installing reinforcing steel (rebar) in the main span pile caps and the precast approach span pile caps.

With only a small percentage of piles left to install, pile driving operations will continue next week. The periodic 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 limited concrete placement for foundations near the South Nyack shoreline. The concrete for this work is being acquired from local concrete suppliers and delivered by truck to the Rockland trestle located off the New York State Thruway’s (I-87/I-287) 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
  • Landing abutment concrete work
  • River Road utility work
  • Support for river-based work from the Rockland trestle
  • Survey inspections on the existing bridge
