Print Friendly

For immediate release: Dec. 22, 2015


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.

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 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.
