The Benjamin Franklin Bridge originally named the Delaware River Bridge, is a suspension bridge across the Delaware River connecting Philadelphia, Pennsylvania and Camden, New Jersey. Named for American founding father Benjamin Franklin, the bridge is owned and operated by the Delaware River Port Authority. The chief engineer was Polish-born Ralph Modjeski, its design engineer was Leon Moisseiff, and the supervising architect was Paul Philippe Cret. At its completion on July 1, 1926, its 1,750 foot (533 meter) span made it the world's longest suspension bridge span, a distinction it would hold until the opening of the Ambassador Bridge in 1929.
The bridge currently carries highways I-676 and US 30, the latter since its opening or very soon thereafter. Before the 1953 New Jersey State Highway renumbering, Route 25, Route 43 and Route 45 ended in the middle of the bridge. The bridge also carries the Port Authority Transit Corporation's Lindenwold High-Speed Line (PATCO Speedline) via connecting tunnels on both sides of the bridge. Pedestrian walkways run along both sides of the bridge, elevated over and separated from the vehicular lanes; of these, only one is open at a time. Walkway hours are 8:00 a.m. to 8:00 p.m. The DRPA temporarily closed the walkways to the public the day after the 7 July 2005 London bombings, citing security concerns. The DRPA also closes the walkway after snowfall, or if the weather forecast includes a chance of snowfall, and closed it in late August 2011 during Hurricane Irene.
