Tappan Zee Constructors (TZC) is scheduled to slightly relocate two lanes of northbound/westbound traffic near the new bridge’s Tarrytown landing during the overnight of Friday, Nov. 30, weather permitting.
The new traffic pattern will temporarily split the four northbound/westbound lanes on the New York State Thruway (I-87/I-287), allowing TZC to continue roadway work in the area. The two pairs of lanes will merge on the Governor Mario M. Cuomo Bridge just after the Westchester approach.
Preparation and implementation of the traffic switch will require lane closures on the northbound/westbound Thruway during the overnights of Thursday, Nov. 29, and Friday, Nov. 30.
Once the operation is complete, all four northbound/westbound traffic lanes and shoulders will be reopened in the temporary configuration. This traffic pattern will remain in effect until the pertinent roadway work is completed early next year. The anticipated roadway work includes replacing the Thruway’s existing driving surface with new precast concrete slabs and pavement.
Additional Roadway Work
TZC is also scheduled to continue roadway improvements and concrete slab installation on the Thruway near the Westchester landing. The work will require overnight double-lane closures on the northbound/westbound Thruway next week.
Striping operations on the bridge will require a single-lane closure on the southbound/eastbound span on Thursday, Nov. 29.

Bicycle/Pedestrian Path
TZC will continue to install rebar and pour concrete on the northern side of the westbound span for the bridge’s shared-use bicycle/pedestrian path and overlooks. 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 Westchester Landing, foundation construction continues at the site of the Welcome Center and storage facility. Operations include backfilling, stripping formwork, pouring concrete and rebar installation.
At the Rockland Landing, a section of the Esposito Trail from Clinton Avenue and South Franklin Street to South Nyack Village Hall remains closed for the construction of the side path. Pedestrians and cyclists are being detoured to South Broadway and through Elizabeth Place Park.
Additionally, crews will continue construction of a retaining wall 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. Crews will soon begin drilling and installing piles at Elizabeth Place Park for construction of a highway noise barrier.
Additional work includes:
- Excavation, grading, landscaping and installing concrete slabs near bridge landings
- Internal tower work, electronic equipment installation and testing
- Dismantling of the old bridge’s pile caps, piles and the Rockland trestle
- Base paving and 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.
