Limited Construction Operations
Due to the continued extreme winter weather and long-range forecasts, TZC will limit construction operations for the next several weeks effective today. Key factors include the safety of TZC personnel and the ability to make meaningful construction progress. During this time, TZC will maintain essential personnel to ensure the safety and security of the project site.

TZC’s inclement weather preparation protocols include having marine vessels on the water at all times, inspecting and adjusting all mooring lines, inspecting crane barges and securing all equipment, moving the large majority of cranes to shallow water moorings and taking all smaller crew boats out of the water. Additionally throughout every storm, TZC uses video and GPS to monitor the entire fleet of project vessels from its security operations center.

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.
