Warnings, Time Frames, and a Diagram

The Regulated Navigation Area (RNA) — established September 15 by the U.S. Coast Guard for the navigable Hudson River waters surrounding the Tappan Zee Bridge — will be enforced until December 31, 2018. Comments and related material pertaining to the RNA will be accepted and reviewed by the Coast Guard through December 31, 2018.

The Coast Guard boating safety information — excerpted and in its entirety — is listed under Boater Safety Information on the New NY Bridge website.

Work on the Rockland access trestle and cofferdams north of the bridge, extending 1,040 feet west from the Westchester shoreline, continues through November 2013. Dredging continues through October 2013; the pile load test program is scheduled to continue through November 2013.

Note the four (4) equipment moorings on the west side of the navigation channel. 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.

The USCG Permit is also posted on the New NY Bridge website:


Activity in the river means BE EXTRA CAREFUL. Can’t say it enough: Numerous units of floating construction equipment will be operating in waterway north of the existing bridge — including crew boats, tugboats, barge mounted cranes and barges.

I’d like to know what you think.
