Lanes Remain Open on TZ Bridge thru the Holiday week3end

December 22, 2015 by

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.

Lane Closures Near the Tappan Zee Bridge

DATE: CLOSURES BEGIN: CLOSURES END: LOCATION:
Tue., 12/22 8 p.m. – One right lane
9 p.m. – Two right lanes		 5 a.m., Wed., 12/23 Southbound I-87/I-287
from exit 12 to exit 10
Wed., 12/23 8 p.m. – One right lane
9 p.m. – Two right lanes		 5 a.m., Thu., 12/24 Southbound
from exit 12 to exit 10

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.

The Steady March of Progress:
Aerial Photos Capture Latest Project Advances
As the installation of road deck panels continues into the fall and steel-blue girders extend even further out over the Hudson River, the New NY Bridge continues its steady march towards completion. Another sign of progress: the increasingly noticeable height of the main span towers, which are growing closer to their ultimate height of 419 feet.

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.
