Tappan Zee Constructors (TZC) is scheduled to continue installing new precast concrete slabs near the bridge’s Westchester landing. The work will create a new base roadway for the twin-span crossing’s connection to the Thruway when the second span opens later this year and require overnight lane closures on the northbound New York State Thruway (I-87/I-287).

Boater Safety
Periodic closures of the main navigation channel are anticipated to occur during construction and demolition periods. Cranes, barges and other equipment will occupy parts of the channel during this time. Boaters are strongly encouraged to avoid the project site during the closures and to avoid the Regulated Navigation Areas, located east and west of the main channel.
Times and dates of the closures are subject to change and will appear in the U.S. Coast Guard’s weekly Notice to Mariners; on the project’s Twitter feed (@NewNYBridge); and broadcast on Marine Radio Channel 22A. Tappan Zee Constructors can be contacted via Marine Radio Channel 16 for assistance.
Rockland and Westchester marine units continue to patrol the project site.
