Construction Begins On New Maintenance Facility Tarrytown Toll Plaza Demolition Continues

May 12, 2016

Tappan Zee Constructors, LLC (TZC) began site preparation and foundation work on the New York State Thruway Authority’s new maintenance facility in Tarrytown this week. The state-of-the-art building will facilitate instant access to the bridge for several groups of Thruway personnel including: administration, emergency response, mechanics, welders, painters, electricians and dock crews. The facility is expected to open in 2018.

Bridge maintenance teams currently operate from a temporary facility near exit 12 in West Nyack.

Tarrytown Toll Plaza Demolition
Demolition of the deactivated toll plaza in Tarrytown continues as TZC removes concrete barriers to create four unobstructed lanes for travelers on the southbound New York State Thruway (I-87/I-287). This will prepare the area for the next shift in traffic, which is scheduled to occur on Friday, May 20.

Work will necessitate lane closures at the former toll plaza throughout the weekend. Specific lane closure times are detailed in the chart below.


Fri., 5/13 9 p.m. – Two right lanes 8 a.m., Sat., 5/14 Southbound Thruway

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 in 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
  • Utility work at the Westchester landings
  • 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 soon begin working in the main navigation channel, which will result in its partial or total closure. 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 and construction site map can be found at 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.
