Motorists in Rockland County are being advised of a significant upcoming traffic change that will impact travel in the Town of Clarkstown for several months.

The New York State Department of Transportation announced that the ramp from the southbound Palisades Interstate Parkway to Exit 9W (Interstate 87 northbound) will be closed beginning Wednesday, March 25 at 12:00 a.m. The closure is expected to remain in effect through mid-November, weather permitting, as crews undertake major bridge rehabilitation work.

Officials say the closure is necessary to facilitate the removal of the bridge deck on the State Route 304 overpass, along with additional construction including replacement of bridge pedestals and bearings, as well as utility installation throughout the 2026 construction season.

Motorists are urged to follow posted detours and plan for potential delays when traveling through the area.

Assemblyman Aron Wieder, who reached out to the State DOT regarding the closure, relayed that while the extended shutdown may cause inconvenience, the project is critical. State officials emphasized that the scope of work required for the Route 304 bridge rehabilitation is more extensive than originally anticipated, and thanked the public for their continued patience during the construction process.
