New York recently completed the $23.6 million State Route 9W project.
The project included the rehabilitation of three bridges and the replacement of four others in the Orange County towns of New Windsor, Cornwall and Highlands. Other improvements included weather-resistant steel girders, concrete arch and substructure repairs, increased vertical clearances, new road surfaces, and new parapets, railings and sidewalks.
Workers created a natural filtration system using bioretention elements, and heavy stone fill was added at the Black Forest Creek location to fix scour and erosion at inlets and outlets.
The project was designed to improve travel and enhance safety.
“All across New York, we are building a sustainable and resilient transportation infrastructure that will strengthen communities and promote growth,” Marie Therese Dominguez, Department of Transportation commissioner, said.
State Route 9W is vital for travel and commerce in the Hudson Valley and provides access to the United States Military Academy at West Point and attractions like Storm King Mountain.
During construction, recycling techniques were employed to reduce the project’s environmental impact and reduce the demand for new materials. Embankment materials were excavated, stockpiled and used as backfill on the new bridges, slopes and roadways. Concrete debris was taken from the bridge sites and transported to a local facility.
