The Bronx River Pathway is located within the Bronx River Reservation, an 807-acre linear park created as an adjunct to the construction of the Bronx River Parkway that was opened in 1925. The parkway, which has the distinction of being the first parkway in the nation, extends 13.2 miles in Westchester from the New York City line north to the Kensico Dam Plaza in Valhalla.
The Pathway consists of three paved segments: a one-mile loop near Oak Street in Mount Vernon; a 3.6-mile section from Palmer Road in Bronxville north to Harney Road in Scarsdale and a 5-mile section extending from Green Acres Avenue in Hartsdale to Kensico Dam Plaza in Valhalla.
