River Road To Re-Open In South Nyack Dismantling Operations Progress in Rockland and Westchester

November 3, 2017

Tappan Zee Constructors (TZC) has completed major dismantling operations of the Tappan Zee Bridge above River Road in South Nyack/Grandview, including the removal of the old bridge’s abutment. The road is expected to be re-opened to vehicular traffic and pedestrians this evening.

TZC will continue dismantling operations above the Hudson River next week, removing large sections of concrete and steel with mobile cranes, including the project’s largest crane I Lift NY. The super crane is scheduled to be relocated near the Westchester landing and assist with removing a section of the old bridge’s steel next week. It will remove 20 similar sections through next spring, the largest weighing more than 1,300 tons.

Demolition materials will be placed onto barges and transported to ancillary facilities including the Port of Coeymans in Albany County.

Roadway Preparation
TZC continues to prepare the second span’s roadway in Rockland and Westchester counties. To prepare the base of the roadway, TZC will continue to install precast concrete slabs near the new bridge’s landings. TZC will utilize noise abatement measures in the areas and continue to monitor noise and vibration levels as work continues.

The operations will require overnight lane closures of New York State Thruway (I-87/I-287) southbound/eastbound traffic lanes from exit 11 (Nyack – South Nyack – US Route 9W) to exit 10 (Nyack – South Nyack – US Route 9W) this week and next week.

Work will also require the overnight closure of the southbound/eastbound Thruway exit 10 on-ramp. Southbound/eastbound drivers will be detoured to the exit 11 on-ramp, shown below.

Maintenance and State Police Facilities
Steel erection for the new State Police Facility in Tarrytown is scheduled to continue this week. Work also progresses on the Thruway Authority’s new maintenance facility in Tarrytown, with the installation of metal panels for the building’s exterior.

Additional work includes:

  • Support for river-based work from the Rockland trestle
  • Pier substructure work
  • Expansion joint operations
  • Internal tower work
  • Maintenance dock construction
  • Electrical equipment installation and testing

Boater Safety
Expect periodic closures of the main navigation channel due to on-going construction and extensive demolition activities. 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.
