TZC Prepares Traffic Shift In Westchester, Rockland

Tappan Zee Constructors (TZC) is scheduled to realign Rockland-bound traffic near the Westchester landing, removing the traffic split, during the overnight of Friday, Jan. 18, weather permitting. The work will require overnight lane closures on the northbound/westbound New York State Thruway (I-87/I-287) starting at 8 p.m. and a temporary closure of the exit 9 (Tarrytown – Sleepy Hollow – US Route 9) northbound on-ramp from 8 p.m. until 6 a.m. Saturday. Northbound/westbound drivers will be detoured to the exit 8 on-ramp.

Additional work and lane closures are scheduled to occur near the Rockland landing during the overnights of Tuesday, Jan. 22, and Wednesday, Jan. 23, weather permitting. At least one Rockland-bound lane will remain open except when State Police stop and temporarily hold traffic for approximately 15 minutes during the early morning hours of Thursday, Jan. 24. There will be no lane closures in the Westchester-bound direction.

The new traffic configuration will allow TZC to continue roadway improvements near the Governor Mario M. Cuomo Bridge.

Specific lane and ramp closure times are listed in the chart below.

Additional work includes:

• Removal of east anchor span materials
• Excavation, grading and barrier installation near bridge landings
• Rebar installation bicycle/pedestrian path barrier
• Dismantling of the old bridge’s pile caps, piles and caissons
• Fence installation 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 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.

More boater safety information, including the U.S. Coast Guard Notice to Mariners, a construction site map and GPS-tracked construction vessel locations, can be found at NewNYBridge.com/Boater.
