Construction of the New NY Bridge continues with pile driving operations between 7 a.m. and 7 p.m. on weekdays, and between 12 noon and 7 p.m. on Saturdays.

A second shift of workers continues pile welding associated with permanent foundations.

Marine crews are working from the shorelines of Rockland and Westchester counties, moving outward to place permanent foundation piles. Work on the foundations for the main span continues to progress as well. To learn more about the main span foundation and tower construction see the new “Bridge Rising” animation on NewNYBridge.com. 

Work continues closer to shorelines on both the Rockland and Westchester temporary work trestles, including pile driving to install the temporary foundation piles needed to support the platforms. The trestles 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.

Enhanced Boater Safety Information is now posted on the project website at NewNYBridge.com under the "Boater Safety" icon including a new map of the project site and information on boater safety enhancements being put into place.  The U.S. Coast Guard will be extending its Regulated Navigation Area (RNA) around the project site to 500 yards north and 500 yards south of the existing bridge. Boaters are advised to proceed with no wake at a maximum speed of five knots in this area, and to transit the main channel when traveling between the north and south sides of the bridge. The RNA also allows the Coast Guard to limit or prohibit marine traffic in those areas if necessary. The New York State Thruway Authority and TZC have also applied for a new safety zone around the 16 construction barge mooring locations at the site. No vessel traffic will be allowed in the safety zone. The Coast Guard boating safety information and the modified mooring permit map can also be found on the project website.
