Tappan Zee Constructors (TZC) is scheduled to continue concrete slab installation on the New York State Thruway (I-87/I-287) near the Rockland landing and roadway improvements on the eastbound span. The work will require single-lane closures near the bridge in both directions.

River Road Work
TZC continues painting operations to the steel girders over River Road in South Nyack, requiring single lane closures and brief, periodic traffic holds. Additional operations include the installation of utilities, sidewalk and curbing.

Travelers should expect brief traffic stops between 7 a.m. and 5:30 p.m., Monday to Friday. The temporary stops are required to safely install the painting platform over the roadway.

Flag persons are on site to facilitate the lane closings and maintain traffic safety. School busses and emergency vehicles are given priority throughout the closure period. Cyclists and pedestrians should follow flagger’s instructions.

Shared-Use Path
In preparation for the bridge’s bicycle/pedestrian path and overlooks, TZC is scheduled to install rebar and formwork on the northern side of the westbound span. The work follows the temporary shift in Rockland-bound traffic to the southern side of the westbound span, allowing TZC to build the path behind temporary concrete barriers.

At the Rockland Landing, a segment of the Esposito Trail from Clinton Avenue and South Franklin Street to Village Hall is closed for the construction of the side path. Pedestrians and cyclists are being detoured to South Broadway and through Elizabeth Place Park.   The detour will be in place for up to two months.

Additionally, crews will continue drilling and installing piles along Hillside Avenue, necessitating temporary lane closures. Flag persons will keep traffic moving by alternating the directional flow between east and west. Ramp construction will also continue for the new connection between Interchange 10 and Hillside Avenue.

Additional work includes:

  • Barrier installation, excavation and paving near bridge landings
  • Internal tower work
  • Dismantling of the old bridge’s pile caps, piles and caissons
  • Internal work on Thruway Maintenance and New York State Police facilities

Boater Safety
The eastern 300 feet of the 600-foot wide main navigation channel is closed to all vessel transits until further notice. Red buoys with all around white light have been set to mark the eastern side of the channel.

Periodic closures of the main navigation channel are anticipated to continue during the demolition period. 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.
