Thruway Authority to Continue Deck Replacement Work on the Tappan Zee Bridge

The New York State Thruway Authority announced today that deck replacement work on the Tappan Zee Bridge will continue next week. This project is part of the Authority’s on-going commitment to continue to fulfill its responsibility to maintain and operate the bridge by continuing to make the necessary investments to assure safe and efficient travel for the thousands of motorists that cross the bridge daily.

The deck replacement project will replace approximately 40 percent of the entire deck, focusing on the two right outside lanes in each direction from the Rockland County shore through the main span. Work will progress in the northbound lanes, followed by replacement work in the southbound lanes covering the same spans.

Work for the week of November 19 will consist of the following:

Panel installation. This operation is weather-dependent and subject to change. Updates will be issued announcing any change in schedule. During this operation:

  • Monday, November 19: Work will begin at 8 PM and result in three southbound lanes closed from 11 PM until 5 AM on Tuesday, November 20, from Interchange 10 (Nyack, South Nyack, Route US 9W) to the Tappan Zee toll barrier. Work will also begin at 8 PM and result in two northbound lanes closed from 11 PM till 6 AM on the Tappan Zee Bridge. These closures are for the grouting of the installed precast concrete panels and joint work on these panels.
  • Tuesday, November 20: Work will begin at 8 PM and result in three southbound lanes closed from 11 PM until 5 AM on Wednesday, November 21, from Interchange 10 (Nyack, South Nyack, Route US 9W) to the Tappan Zee toll barrier.
  • Wednesday, November 14: No work scheduled.
  • Thursday, November 15: No work scheduled.
  • Friday, November 16: No work scheduled.

Traffic updates will be broadcast to motorists via Dynamic Message Signs (DMS) along the highway and by Highway Advisory Radio, 530 AM in the Tappan Zee Bridge corridor, as well as 1610 AM in the Newburgh area.

Motorists may also sign up to receive email and text message traffic updates from the Thruway Authority’s TRANSalert system. Anyone may subscribe to the free service at .

When complete, the new deck, along with related repairs to the superstructure, lighting, and rail will provide more reliable service, increase safety and add convenience for motorists using this vital east-west corridor.

The Authority has implemented a number of measures to reduce the impact on motorists, preserve traffic flow, shorten the project duration, and reduce on-site noise levels. Much of the work is being completed during off-peak, overnight shifts, generally from 8 p.m. to 6 a.m., and redecking materials are being manufactured off-site with delivery just in time for installation.

The three-mile Tappan Zee Bridge, located about 13 miles north of New York City, carries the New York State Thruway over the Hudson River, between Rockland and Westchester Counties. The structure serves as a lifeline between New York City and Upstate New York. The bridge carries over 140,000 vehicles every day, with volumes as high as 170,000 vehicles daily. When the bridge opened in 1955, it carried an average of 18,000 vehicles daily.
