Tappan Zee Constructors, LLC (TZC) completed the demolition of the New York State Thruway Authority’s former maintenance offices in Tarrytown this week. Crews are preparing the site for a new maintenance facility, with construction scheduled to begin in the coming weeks.
Bridge maintenance teams currently operate from a temporary facility near exit 12 in West Nyack.
Thruway Maintenance
The Thruway Authority will replace an overhead sign near the southbound Thruway (I-87/I-287) exit 11 (West Nyack – NY Route 303 – Palisades Center Drive) on-ramp. The work will necessitate closing two lanes of the Thruway during the overnight of Wednesday, March 23. Specific lane closure times are detailed in the chart below.
LANE CLOSURES NEAR THE TAPPAN ZEE BRIDGE
| DATE: | CLOSURES BEGIN: | CLOSURES END: | LOCATION: |
| Wed., 3/23 | 8 p.m. – two left lanes | 5 a.m., Thu., 3/24 | Southbound Thruway From exit 12 to exit 11 |
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 will also 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 to monitor the construction zone. All boaters are advised to obey the established U.S. Coast Guard safety protocols.
Following last weekend’s tragic accident, the New NY Bridge project team reminds all boaters to exercise extreme caution in the construction zone. Relevant excerpts from the U.S. Coast Guard Notice to Mariners can be found here.
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 https://www.thruway.ny.gov/travelers/map/ for real-time information regarding traffic conditions.
