The Delair Bridge is a lift bridge carrying the New Jersey Transit Atlantic City Line and a former Conrail line, now a shared asset between Norfolk Southern Railway and CSX Transportation. It crosses the Delaware River between Philadelphia, Pennsylvania, and Pennsauken Township, New Jersey, just south of the Betsy Ross Bridge. The bridge's southern track is currently reserved for freight traffic, and the northern track is currently reserved for the Atlantic City Line. As part of the upcoming Pennsauken Transit Center project, which will involve building a station complex where the River LINE passes under the Delair Bridge's approach, a station will be constructed on the NJ approach.
Since the Atlantic City Line station portion will use both tracks, both tracks will be used for passenger service in the future, with freight traffic also gaining use of both tracks. In December 2011, an $18.5 million Transportation Investment Generating Economic Recovery (TIGER) grant was awaded to South Jersey Port by the United States
Department of Transportation for rehabilitation of the bridge.
The bridge was also electrified in the late 1930s, allowing freight trains hauled by electric locomotives to access the Pavonia Yard in Camden, New Jersey from the Northeast Corridor. Electrification was removed by January, 1967 but was restored in May 1973. However, Conrail ceased electric freight operations in 1981 and removed the wires several years later. Passenger traffic on the bridge ceased in 1969, but was restored in 1990. A brief shot of the bridge can be seen in the movie Transformers: Revenge of the Fallen from the defunct PECO Richmond power station on the Pennsylvania side of the river.
