Tappan Zee Constructors (TZC) is preparing the final driving surface of the new bridge in anticipation of the traffic shift scheduled for the overnight of Friday, Aug. 25. The operation will shift four northbound/westbound traffic lanes of the New York State Thruway (I-87/I-287) to the first span of the new bridge.
TZC is scheduled to stripe the new bridge’s traffic lanes in the coming days. The work will take place on the westbound span and available areas at the landings.

Boater Safety
Expect periodic closures of the main navigation channel due to on-going construction through the end of this year. 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.
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.
