Due to the this evening’s weather forecast, the transition to the New NY Bridge project’s cashless tolling system is now scheduled to begin during the overnight of Saturday, April 23. Actual activation is scheduled to occur at 12:01 a.m., Sunday, April 24.
Travelers passing through the Tarrytown toll plaza (which will be deactivated when the cashless tolling system in South Nyack goes live) will experience shifting traffic patterns throughout the night, as detailed below. Precise lane closure times will be dependent on traffic volume.
The toll plaza will be reduced to one E-ZPass lane and two cash lanes just before the transition.
The cashless tolling system will be activated after the final driver leaves the Tarrytown toll plaza. All tolls will be collected by the temporary cashless system located in South Nyack after that time. Three lanes will be open to traffic with a speed limit of 20 miles per hour until 6 a.m. while other construction activities take place.
After 6 a.m., an additional five lanes will open to traffic, bringing the total number of open lanes to eight. For safety reasons, traffic passing through the six unstaffed toll plaza lanes on the right will be directed to limit speed to 20 miles per hour, while traffic using the left two lanes may proceed at 35 miles per hour. This configuration will be in effect until the next phase of construction takes place in May.
The transition also will necessitate overnight triple lane closures on the southbound Thruway between exit 10 (Nyack – South Nyack – US Route 9W) and exit 9 (Tarrytown – Sleepy Hollow – US Route 9) on Saturday, April 23. Work will also require closing the exit 10 on-ramp. The graphic below shows detour routes.
In addition, periodic traffic stops lasting up to 10 minutes of all four lanes of the southbound Thruway from exit 11 (Nyack – South Nyack – US Route 9W) to the Tappan Zee Bridge will occur between 11 p.m. and 5 a.m. To ensure the public’s safety, the New York State Police will coordinate the traffic flow.
Specific lane and ramp closures and anticipated times are detailed in the chart below.
| DATE: | CLOSURES BEGIN: | CLOSURES END: | LOCATION: |
| Sat., 4/23 | 9 p.m. – Two right lanes 12 a.m. – Three right lanes |
8 a.m., Sun., 4/24 | Southbound Thruway from exit 10 to exit 9 |
| Sat., 4/23 | 10 p.m. – On-ramp closure | 5 a.m., Sun., 4/24 | Southbound exit 10 |
Pier Foundation Work
Preparations for pier foundation work near the Rockland shoreline scheduled for the weekend of April 29 will necessitate periodic pile driving during daylight hours.
Noise Barrier Construction
TZC will continue constructing noise barriers along the Thruway 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 to 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
- Westchester landings utility work
- Girder assembly placement
- Bridge road deck installation
- Drainage structure installations
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.
Mariners also should be aware that TZC will continue work in the vicinity of the side channels under the existing bridge. TZC will also be working in the area left and right of the main navigation channel under the main span of the bridge. TZC will begin working in the main navigation channel, which will result in partial or total closure of same. 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, 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.
