Old Bridge Dismantling and Removal
TZC is scheduled to further dismantle the old bridge’s west anchor span on a floating barge located south of the bridge. TZC is also preparing the removal of the east anchor span from the project site.
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 and visitor pavilion. Operations include the placement of concrete masonry units, granite walls, benches and structural steel.
At the Rockland Landing, daytime paving of Hillside Avenue from the New York State Thruway ramp to near the South Franklin Street Extension in South Nyack will continue next week, weather permitting. Two-way traffic will be maintained during commuting hours while one-way traffic control measures will be in place during the operation.
Additional work includes:
- Barrier placement, landscaping, pouring concrete, paving and excavation 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, weather permitting
Boater Safety
Partial closures of the main navigation channel may be necessary, as TZC continues to dismantle the Tappan Zee Bridge’s west anchor span and remove the east anchor span.
All vessels should avoid the perimeter of all buoys and stay within the navigation channel as demolition operations continue this coming week.
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.
