Boater Safety

Navigating Around the New NY Bridge Construction Zone

Boater safety on the Hudson River in the area of the New NY Bridge project has been enhanced with new measure instituted by the New York State Thruway Authority, Tappan Zee Constructors, LLC (TZC) and the U.S. Coast Guard.

Construction of the New NY Bridge is in progress and the entire work zone is extremely active. Mariners are strongly advised to adhere to the following guidelines established by the U.S. Coast Guard:

  • Stay clear of all overhead work and maintain a safe distance of 1,000 feet from all construction equipment and support vessels.
  • Use the center 600 feet of the Main Channel to navigate in a north-south direction with no wake at a maximum speed of five knots.
  • Partial or full closures of the Main Channel will periodically occur. View the U.S. Coast Guard First District Local Notice to Mariners for information regarding upcoming closures.
  • All bridge piers and abutments are protected by a 25-yard security zone.
  • No unauthorized vessels are allowed in the Safety Zone surrounding 16 construction barge mooring locations. Lighted buoys mark the zone and mooring locations.
  • Regulated Navigation Areas (RNAs) stretch 500 yards north and 500 yards south of the existing bridge. No vessel may stop, moor, anchor or loiter within the RNAs.
  • The Eastern RNA will be extremely active and vessels transitioning to and from the eastern shoreline at Tarrytown should approach and depart to the north. The Western RNA will be impassable at times and mariners should stay clear of the area.
  • Lighted channel makers provide recreational boater access to the Piermont waterfront.
  • Construction barges and other vessels on the site are being tracked by GPS technology.
  • TZC will monitor Marine Radio Channel 16 to communicate with boaters.

The New York State Thruway Authority provides this information as a public service. Any reliance you place on such information is therefore strictly at your own risk. Nothing in these guidelines shall supersede the actual construction conditions or regulations set forth by the United States Coast Guard.
