Bicycle/Pedestrian Path
Construction of the shared bicycle and pedestrian path continues.

On the bridge, TZC will continue to work on the northern side of the westbound span for the path’s overlooks and fencing.

At the Westchester Landing, construction continues at the terminus site walls, storage building and visitor pavilion. Operations include painting, paving, excavating, installing electrical wiring, concrete masonry units, top soil, roofing, and plumbing. Additional flatwork for the shared bicycle/pedestrian side path is also taking place along Route 9.

At the Rockland Landing, the Thruway Authority is preparing to open the newly reconfigured Interchange 10 during the week of October 7. When complete, vehicles will be able to access the northbound and southbound Thruway from a new signalized intersection at Route 9W and Hillside Avenue. At that time, the current southbound on-ramp from South Broadway will be permanently closed. With this new traffic pattern, riders of the Hudson Link bus service will use two new stops on South Franklin Street Extension. They will replace the current stops at Clinton Avenue and South Broadway.

The exact opening date of the revised Interchange 10 configuration will be announced soon.

You can download a printable version of the Interchange 10 directional maps here.            

Also, two new traffic signals are expected to be activated early next week. They are located at the intersection of Clinton Avenue and South Franklin Street and at South Franklin Street Extension and Hillside Avenue.

Additional work includes:

  • Fencing, signage, drainage work, landscaping, and pouring concrete near bridge landings
  • Area preparation at the New York State Thruway Maintenance and New York State Police facilities
  • Dismantling of the old bridge’s foundations, weather permitting

Boater Safety
Partial closures of the main navigation channel may be necessary.

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.
