Thruway Authority to Continue Tappan Zee Bridge Deck Replacement Work

The New York State Thruway Authority announced today that construction work related to the deck replacement project on the Tappan Zee Bridge will take place tonight, Friday, January 4, continuing overnight until early Saturday morning, January 5.

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.

Asphalt testing and joint replacement survey. This operation is weather-dependent and subject to change. Updates will be issued announcing any change in schedule. Lane closures during this operation:

  • Friday, January 4 - Saturday, January 5: Work will begin at 8 PM, Friday night and result in two left lanes closed, southbound, at 8 PM (Friday) until 6 AM (Saturday). In addition, a third southbound lane will be closed starting at 12 midnight until 6 AM (Saturday morning). The work zone extends from Interchange 11 to Span 173 (mid-bridge) on the southbound roadway.
  • Friday, January 4 - Saturday, January 5: Work will begin at 10 PM, Friday night and result in one left lane closed, northbound, at 10 PM (Friday) until 6 AM (Saturday morning). In addition, a second lane will be closed starting at 12 midnight until 6 AM (Saturday morning). The work zone extends from Interchange 8 towards the east abutment on the Tappan Zee Bridge along the northbound roadway.

All lanes are expected to be opened to traffic by 6 AM Saturday morning.

For the safety of the public and construction workers, motorists are urged to proceed with caution and obey posted work-zone speed limits. Work will proceed weather-permitting, and schedule updates will be announced as needed.

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.
