TZB Closes; All Traffic on New Span

The original Tappan Zee Bridge is now officially closed. The last car, as you just heard, made its way from Nyack to Tarrytown around 7pm Friday night. There are now eight lanes of traffic on the first span, four heading northbound to Rockland and four heading southbound to Tarrytown. With all eight traffic lanes on the new bridge’s first span, the landings of the old bridge, which occupy the same footprint of the second span, can be demolished. The second span will then be connected to land and the structure will be completed. The initial demolition project will force the closure of River Road in South Nyack-Grand View underneath the Tappan Zee Bridge for up to four weeks.

River Road Closures
TZC is preparing to remove the existing Tappan Zee Bridge to complete the second span of the new bridge. The initial demolition effort will require a complete closure of the portion of River Road in South Nyack/Grand View that crosses underneath the Tappan Zee Bridge for up to four weeks. The work will require the use of mobile cranes and other equipment as TZC removes large sections of concrete and steel from the area, employing noise mitigation techniques to minimize impacts to residents. The closure is scheduled to begin on Tuesday, Oct. 10, and extend into early November, six days per week (Monday through Saturday), between the hours of 6 a.m. and 10 p.m.

To safely accomplish the demolition, TZC and the New York State Thruway Authority are working closely with emergency and first responder agencies, Rockland County transportation officials, elected officials, affected school districts, and commercial bus companies that service the area. Alternate routes commuter bus services have also been established. The closure site will be monitored 24/7 by project safety personnel who will provide temporary access for emergency service vehicles at all times.

Vehicular traffic will be detoured to 9W, while pedestrians and cyclists will have limited access to River Road after extended waiting periods. Project safety personnel will hold pedestrians and cyclists for up to an hour on weekdays and up to 15 minutes on Saturdays. Access will be provided without extended waiting periods on Sundays, however the Thruway Authority strongly encourages travelers to avoid the area until construction operations conclude in early November.

Additional work includes:

  • Support for river-based work from the Rockland trestle
  • Survey inspections on the existing bridge
  • Pier substructure work
  • Expansion joint operations
  • Internal tower work
  • Maintenance dock construction
  • Electrical equipment installation and testing
  • Construction of maintenance and state police facilities

Boater Safety
Expect periodic closures of the main navigation channel due to on-going construction through the end of this year. 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.

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.
