A busy Westchester corridor used by thousands of drivers, walkers and cyclists each day is getting a major safety upgrade.

The federal government awarded $25 million Tuesday, July 7, to improve a 1.5-mile stretch of U.S. Route 9 with new roundabouts, traffic signals, wider sidewalks and safer pedestrian crossings.

The grant is part of a nationwide infrastructure program aimed at improving transportation safety and reducing congestion. The Route 9 project was the largest of two New York projects included in the latest round of funding.

The exact location of the work has not yet been announced. Route 9 runs through several Westchester communities, including Yonkers, Hastings-on-Hudson, Dobbs Ferry, Ardsley, Tarrytown and Sleepy Hollow.

For local drivers, the upgrades could mean fewer bottlenecks and safer intersections. For pedestrians and cyclists, the project is expected to address long-standing concerns about crossing one of the county’s busiest roads.

What we know — and what’s next

The U.S. Department of Transportation has not released a construction timeline, start date or specific intersections included in the project.

The funding came through the federal BUILD program, which awarded $1.73 billion nationwide after receiving nearly 1,200 applications requesting more than $14.5 billion.

Officials have not announced when residents can expect to see construction begin.
