The High Bridge (originally the Aqueduct Bridge) is the oldest bridge in New York City, having originally opened as an aqueduct in 1848 and reopened as a pedestrian walkway in 2015 after being closed for over 40 years. A steel arch bridge, with a height of almost 140 feet (40 m) over the Harlem River, it connects the New York City boroughs of the Bronx and Manhattan. The eastern end is located in the Highbridge section of the Bronx near the western end of West 170th Street, and the western end is located in Highbridge Park in Manhattan, roughly parallel to the end of West 174th Street.
