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.
The U.S. Coast Guard has established a Safety Zone surrounding 16 construction barge mooring locations at the site. No unauthorized vessels are allowed in the Safety Zone.
- Lighted buoys mark the Safety Zone* and mooring locations on the water.
- Lighted channel markers provide recreational boater access to the Piermont waterfront*.
- The U.S. Coast Guard has established 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.
- No vessel may stop, moor, anchor or loiter within the RNAs.
- Additional safety signage has been installed to alert boaters of the RNAs.
- The Coast Guard advises all boaters to transit the main channel with no wake at a maximum speed of five knots.
- TZC barges and other vessels on the site are being tracked by GPS technology; boaters can view vessel locations above.
- An electronic “geo-fence” will notify project safety officials if a TZC vessel leaves the designated construction zone.
- TZC will monitor Marine Radio Channel 16 to communicate with boaters.
- Review the Coast Guard Notice to Mariners for regular updates.

In October 2013, temporary navigational lights were relocated as per the diagram below at the existing Tappan Zee Bridge across the Hudson River at mile 27.0. The new temporary navigational lighting plan includes marking the 600 foot wide main channel by affixing four-180° steady, red navigation lights to the underside of the main span, 2 each on the upstream and downstream sides of the structure, 300 feet either side of the centerline of the bridge. Each green center of channel light has 3 white lights stacked vertically above it. The center 600′ feet of the Main Navigation Channel will be free for the passage of marine traffic and clear of all obstructions at all times.
- U.S. Army Corps of Engineers Approved Mooring Locations
The map below is from the January 14, 2014 U.S. Army Corps of Engineers permit modification for the New NY Bridge Project to replace the Tappan Zee. It shows the approved temporary mooring locations for construction barges on the Hudson River during the project. There will be barges moored at these approved locations both day and night during the project and there will be up to 100 barges, crew boats and other vessels in the area at the peak of construction. Originally, there were 4 mooring locations established in the spring of 2013. 12 additional areas have been approved and the initial 4 will also be reconfigured. The U.S. Coast Guard has issued the following guidance in its Notice to Mariners: “When transiting the area mariners should stay clear of these locations by a minimum of 1000 feet. Mariners are advised to transit the main channel, reduce wake and use extreme caution while transiting the area in the vicinity of the Tappan Zee Bridge paying particular attention to vessel movement and future notices.
