Tappan Zee Constructors (TZC) is scheduled to continue roadway improvements near the Governor Mario M. Cuomo Bridge. Paving of the southbound exit 9 (Tarrytown – Sleepy Hollow – US Route 9) off- ramp requires multiple overnight lane closures on the southbound New York State Thruway (I-87/I-287).
Drivers will be detoured approximately one mile west to exit 8A (Elmsford – NY Route 119 – Saw Mill River Parkway North) to access the northbound Thruway and the northbound exit 9 off-ramp (see map below).
At least one lane will remain open at all times. Specific lane and ramp closure times are listed in the chart below.

Old Bridge Dismantling and Removal
Following the lowering of the old bridge’s west anchor span this week, TZC is scheduled to further dismantle the structure on a floating barge, located south of the bridge. TZC is also preparing to salvage and remove the east anchor span from the Hudson River in the coming weeks.
Bicycle/Pedestrian Path
Construction of the shared bicycle and pedestrian path continues.
On the bridge, TZC will continue to install glass panels on the northern side of the westbound span for the path’s overlooks and work on the path’s barrier.
At the Westchester Landing, construction continues at the terminus site walls, storage building, visitor pavilion and canopy area. Operations include the placement of concrete masonry units, rebar, roof steel and pouring concrete.
Additional work includes:
- Barrier placement, landscaping, pouring concrete and installing subbase near bridge landings
- Internal work and fence installation at the New York State Thruway Maintenance and New York State Police facilities
- Dismantling of the old bridge’s foundations, weather permitting
Boater Safety
Periodic partial closures of the main navigation channel may be necessary, as TZC continues to dismantle the Tappan Zee Bridge’s west anchor span and salvage the collapsed east anchor span. Cranes, barges and other equipment may 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 potential, partial 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.
