THRUWAY UNVEILS UPDATED PROJECT WEBSITE
All-Electronic Tolling System Work Requires Overnight Closure of Exit 10 On-Ramp on Friday, Nov. 20
The New York State Thruway Authority launched an updated NewNYBridge.com this week, featuring an easier-to-navigate interface, a comprehensive archive of project photos, videos and renderings, and a wealth of background information covering how the new crossing was studied and designed and is being built. Visit the new site and check back frequently for the latest updates on the fast-moving construction progress.
Steel Girder Installation
Tappan Zee Constructors, LLC (TZC) will continue installing steel girders near the Rockland shoreline, connecting the new bridges abutment to already-installed support structures in the Hudson River. Safely accomplishing the work will require reducing River Road/Piermont Avenue 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. TZC also will hold traffic on River Road once daily between 9 a.m. and 3 p.m. for up to 20 minutes through Wednesday, Nov. 18 to enable the safe movement of girders and other materials.
Across the river, TZC will continue installing structural steel girder assemblies from the new bridges Westchester landing in Tarrytown. The assemblies will connect the future westbound spans 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 Lines 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, 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, one in November and one in December. The work will be announced in advance to enable Metro-North riders to plan ahead. Metro-North has adjusted its schedule slightly to allow the work to be completed. TZC will suspend construction activities when trains pass through the area, resuming when given the all clear instruction by Metro-North.
Additionally, the I Lift NY super crane will continue placing larger girders across the Hudson 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 projects 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 overnight of Friday, Nov. 20. Drivers will be directed to use the on-ramp from Route 59 in Nyack, as shown in the graphic below. The work also requires double-lane closures during weekday overnights from Monday, Nov. 16 through Thursday, Nov. 19. This and other work require the specific lane and ramp closures detailed in the chart below.

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.
