Multimodal Project along Route 9/South Broadway Over I-87/I-287 in Tarrytown

Project Background

In Spring 2023, the New York State Thruway Authority and New York State Department of Transportation began a $13.9 million multimodal project along Route 9 (South Broadway) in Tarrytown to extend the Governor Mario M. Cuomo Bridge side path one mile south to Lyndhurst Mansion, where pedestrians and cyclists will be able to seamlessly connect with the Old Croton Aqueduct Trail. The project includes the construction of a 270-foot-long pedestrian/bicycle bridge over the Thruway (I-87/I-287) to improve access and enhance safety for pedestrians and cyclists. The new span will be 16 feet wide and 15 feet tall. The majority of construction will take place during the day; some work that requires Thruway lane closures will occur at night for the safety of workers and to limit impacts to traffic. The project is anticipated to be substantially completed by the end of 2024.

Project Improvements

Major elements of the project include:

  • Construction of a 270-foot-long pedestrian/bicycle bridge over the Thruway
  • Widening the ramps at Thruway Interchange 9 leading to and from Route 9
  • Adding a second left turn lane from Route 9 to the southbound Thruway entrance ramp
  • Installing a traffic signal on Route 9 at Paulding Avenue to make it easier for motorists to turn
  • Repairing and resurfacing Route 9 from Route 119 to just south of Gracemere Lane
  • Relocating a village of Tarrytown water main onto the existing Route 9 bridge
Project Construction

Beginning in late May/early June 2024, new temporary traffic patterns will be in place on Route 9—just north of Route 119 past Paulding Avenue—to facilitate the assembly of the new pedestrian/bicycle bridge (see graphics below).

  • During working hours, there will be one lane open in each direction on weekdays from 9:30 a.m. to 3 p.m.
  • During non-working hours, two lanes in each direction will be available to traffic.
  • This traffic pattern is anticipated to remain in place until mid-July 2024.
  • The speed limit in the work zone will be 25 mph.
  • Pedestrian access will be maintained; pedestrians can cross Route 9 on its east side at the intersection of Route 119 or by the Thruway interchange.
  • Multiple flaggers will be in the vicinity of the work zone.
  • Motorists should give themselves extra time if they plan to travel in this area.
