Construction will continue in the Hudson River as crews place the foundation for the New NY Bridge. Work will include pile driving between 7 a.m. and 7 p.m., Monday through Friday and noon to 7 p.m. on Saturday.
A second shift of workers will continue work that is less intrusive to the public, including pile welding, pile cleanout and concrete placement operations associated with permanent foundations.
Tappan Zee Constructors, LLC (TZC) will continue constructing the new bridge’s Westchester landing, drilling shafts into the bedrock for its foundation. The drilling process produces less noise than the impact pile driving alternative and TZC has implemented other sound-reducing measures to further minimize noise levels. The operation is expected to conclude in November.
Work also will continue on the Rockland work trestle near the shoreline, including pile driving and cofferdam installation. The trestle will support equipment used for the construction of the westernmost section of the new bridge.
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 inside 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 atNewNYBridge.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 this very active construction zone. The GPS tracking map is for informational purposes and not intended for navigation.
Mariners 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.
