New York Governor Kathy Hochul has announced the completed construction of a $23.6 million project to replace four bridges and rehabilitate three others along State Route 9W in the towns of New Windsor, Cornwall and Highlands in Orange County.

According to a release, extensive recycling techniques were also employed during construction to reduce the demand for new materials and reduce the project's environmental impact.

"New York State remains committed to building a 21st century infrastructure that improves quality of life, promotes economic growth and helps to safeguard our environment," Hochul said. "Renewing the bridges along the Route 9W corridor will help countless commuters who travel this vital corridor every day and help keep people and goods moving throughout Orange County for years into the future."

Improvements made as part of the project include new road surfaces, increased vertical clearances, concrete arch and substructure repairs, and new parapets, railings and sidewalks. New, weather resistant steel girders were also installed to significantly lengthen the life span of the bridges and lessen the need for frequent painting. 

During construction, concrete debris was taken from the bridge sites and transported to a local facility, where it was reduced and processed for use as backfill, subbase and gravel. Additionally, embankment materials were excavated, stockpiled and utilized as backfill on the new bridges, slopes and roadways.

Bioretention elements were added to create a natural filtration system, which protects wildlife and prevents adverse impacts from stormwater runoff. Stone armoring, also known as heavy stone fill, was added at the Black Forest Creek location to fix scour and erosion at inlets and outlets, which will allow for the free flow of water.

“All across New York, we are building a sustainable and resilient transportation infrastructure that will strengthen communities and promote growth. This project along the Route 9W corridor is no exception and demonstrates the Department of Transportation's commitment to giving New Yorkers the transportation system they deserve and utilizing sound and environmentally conscious methods and materials,” said Department of Transportation Commissioner Marie Therese Dominguez.
