For immediate release: March 14, 2014


Tappan Zee Constructors, LLC (TZC) continues construction of the New NY Bridge the week of March 17. This construction includes pile driving operations between 7 a.m. and 7 p.m. on weekdays, and between noon and 7 p.m. on Saturdays.  A second shift of workers continues work on the permanent foundation piles.   

Work continues closer to shorelines on both the Rockland and Westchester temporary trestles, including daytime pile driving to install the temporary foundation piles needed to support the platform. The trestles are work platforms that will support cranes for the construction of the eastern- and western-most sections of the new bridge.

Mariners should be aware that TZC will continue installing permanent piles in the vicinity of the side channels under the existing bridge, weather permitting. Additional temporary navigational lights have been installed to further define the 600-foot navigation channel under the main span. Both temporary and permanent piles are illuminated at night.

The U.S. Coast Guard has issued a revised Notice to Mariners with updated safety information, including the establishment of a Regulated Navigation Area (RNA) – 300 yards north and 200 yards south of the existing Tappan Zee Bridge. The U.S. Army Corps of Engineers has issued a modified permit for additional temporary mooring locations during construction of the new bridge. All boaters are advised to use the main channel, reduce wake and use extreme caution while transiting the area. If necessary, the Coast Guard may temporarily prohibit all vessel traffic in the RNA for safety purposes. The Coast Guard boating safety information and the modified mooring permit map can be found on the project website at under the "Boater Safety" icon.
