For immediate release: December 13, 2013


Construction activity continues on the foundation of the New NY Bridge with the ongoing installation of permanent piles.

Excavation and preparation work for installation of permanent sound barriers continues along I-87 northbound/I-287 westbound in the area south of exit 10 in Rockland County.

On Monday, Dec. 16, and Tuesday, Dec. 17, the northbound right-hand lane and shoulder on I-87/I-287 near exit 10 in Nyack will be closed from 10 a.m. to 3 p.m. The same section of roadway will be closed on Friday, Dec. 20, from 10 a.m. to 1 p.m.

On Wednesday, Dec. 18, and Thursday, Dec. 19, the southbound right-hand lane and shoulder on I-87/I-287 near exit 10 in Nyack will be closed from 10 a.m. to 3 p.m. to allow for work on the Thruway Authority’s southbound maintenance ramp.  

Mariners should be aware that Tappan Zee Constructors, LLC (TZC) will be installing permanent piles in the vicinity of the side channels under the existing bridge. Pile driving will take place between 7 a.m. and 7 p.m. on weekdays, and occasionally between noon and 7 p.m. on Saturdays. New 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. All boaters are advised to use the main channel, reduce wake and use extreme caution while transiting the area. If necessary, the Coast Guard in the future may temporarily prohibit all vessel traffic in the RNA for safety purposes. The Coast Guard boating safety information can be found on the project website under the “Boating Safety” icon.
