$9.1 Million Hudson Valley Roadway Projects Underway to Improve Safety, Pavement, and Travel

By Rockland Daily Staff

Construction has begun on three major roadway projects in the Hudson Valley, representing a $9.1 million investment to improve pavement, enhance resiliency, and boost safety along key stretches of State Route 100A and State Route 134 in Westchester County and U.S. Route 9W.

The work on State Route 100A, also known as Knollwood Road, covers a 2.7-mile section between State Route 100B and State Route 100C/100 (Grasslands Road) in the Village of Elmsford and the Town of Greenburgh, with a $4.9 million budget. The project aims to strengthen a vital connection to Interstate 287 and the Sprain Brook Parkway.

State Route 134 will be resurfaced along a two-mile stretch from State Route 9A in Ossining to the New Castle town line, with $2 million allocated for the improvements. Meanwhile, U.S. Route 9W in Ulster County will undergo a $2.2 million repaving project covering 4.7 miles between Canal Street in Port Ewen and State Route 32 in the Town of Ulster, including the Delaware Avenue ramps.

All projects feature milling and resurfacing with warm-mix fiber-reinforced asphalt, designed for longer-lasting durability and reduced cracking. Grooved inlaid striping with reflective epoxy paint will be installed to improve visibility in adverse weather conditions, and upgrades will include traffic signals, improved drainage, and ADA-compliant curb ramps where applicable.

The majority of the work will take place during nighttime hours with single-lane closures during paving operations to minimize disruptions for drivers. Completion is expected by the end of the 2025 construction season.

The projects are part of broader efforts by the New York State Department of Transportation to modernize infrastructure across the Hudson Valley, enhance safety, support economic development, and ensure the long-term durability of the region’s roadways.
