The bridge is named because it carries Broadway, which is designated as US 9 here. The bridge also carries the IRT Broadway–Seventh Avenue Line ({{NYCS trains|Broadway-Seventh north}}) above the road. HistoryBefore the Harlem River was rerouted, the bridge in the area was named Kings Bridge, crossing the river on the border between Marble Hill and the Bronx. The Boston Post Road and Albany Post Road crossed this bridge. A later bridge, opened on January 1, 1895, spanned the canal. A total of three bridges spanned the canal at this location. The 1895 bridge, a steam-powered swinging bridge, accommodated only highway and pedestrian traffic. It was replaced in 1905 by a bridge that could accommodate for the extension of the IRT subway line into the Bronx. The 1905 Broadway Bridge was also a swinging bridge, but a second deck was added to allow for subway traffic on the upper deck, and pedestrian and highway traffic on the lower deck.[2] The 1905 iteration of the Broadway Bridge, that was being replaced by a new double-level structure,[3] was reused to create the University Heights Bridge. In June 1906, the old bridge was floated down the river and placed on a newly constructed center pier. After all the approaches and other construction were completed, the new University Heights Bridge opened to traffic on January 8, 1908.[4] The present Broadway Bridge (opened on July 1, 1962) has a navigable channel {{convert|304|ft|m}} wide providing {{convert|136|ft|m}} of vertical clearance when the bridge is in the open position. In the down position, the bridge provides {{convert|24|ft|m}} of vertical clearance. TrafficIn 2010, the New York City Department of Transportation, which operates and maintains the bridge, reported an average daily traffic volume in both directions of 37,292. The peak ADT over the Broadway Bridge was 42,555 vehicles in 1990.[5] Public transportationThe Broadway Bridge carries the New York City Subway's {{NYCS trains|Broadway-Seventh north}}. As such, when the bridge is open, 1 trains terminate at 215th Street. Shuttle buses provide service to Van Cortlandt Park-242nd Street. Immediately to the north of the bridge along this line is the Marble Hill–225th Street station.[6] The bridge also carries the {{NYC bus link|Bx7|Bx20|prose=y}} local bus routes operated by MTA New York City Transit, and the {{NYC bus link|BxM1}} express bus route operated by the MTA Bus Company.[7] See also
