The state Department of Transportation closed Route 59 in the Village of Spring Valley between New Clarkstown Road and South Pascack Road for a bridge rehabilitation project, with the closure beginning around May 21 and expected to last through late spring and summer, per an NYSDOT traveler advisory, May 27, 2026. The work targets the Route 59 bridge over South Pascack Road, a connector between the Towns of Clarkstown and Ramapo.
Route 59 is one of the busiest commercial corridors in Rockland County, and the closure lands on a stretch lined with plazas, medical offices and schools. NYSDOT posted detours and held a public open house before construction to walk residents and business owners through the schedule, per Rockland Daily. An update posted in June indicated the project, begun June 3, was proceeding on its expected timeline.
For Rockland commuters and deliveries, the practical effect is a months-long shuffle onto parallel streets in Spring Valley and Monsey, with the usual knock-on congestion at signalized intersections that were not designed for diverted volumes. Local police and village officials have urged patience around school-adjacent blocks during drop-off hours.
The bridge project is not the only state work on the corridor. NYSDOT's Region 8 office has also announced a public workshop for a separate Routes 59 and 45 project in Rockland County, per the agency's regional press releases, signaling that the corridor will see staged state investment over multiple seasons.

For businesses along the closed stretch, the playbook is the one that worked in prior county paving years: clear wayfinding, coordinated signage and customers who know the detour. The state says the work is a rehabilitation, not a replacement, which typically means a shorter construction window than a full bridge rebuild.
Planning matters more than speed on this corridor. County commuters who connect to the Palisades Interstate Parkway or the Garden State Parkway via Route 59 should build in extra time on weekday mornings, and through-truck traffic is better routed to Route 304 or the Thruway where practical. School-year travelers should note that the project's summer window was chosen partly to keep the heaviest disruption out of the September commute, and NYSDOT typically posts schedule changes through its traveler advisory system as work advances.
