The two-track bridge is part of Conrail Shared Assets Operations and is jointly used by Norfolk Southern Railway and CSX Transportation freight trains, as well as by the New Jersey Transit Atlantic City Line service.

It consisted of three fixed Pennsylvania truss spans and a through-truss swing-span drawbridge totaling 1,943 feet (592 m).

[2] Starting in 1958, the PRR converted the bridge into a vertical-lift span to increase clearance for river traffic.

[4] The bridge was also electrified in the late 1930s,[5] allowing freight trains hauled by electric locomotives to access the Pavonia Yard in Camden, New Jersey, from the Northeast Corridor.

As part of the Pennsauken Transit Center project, a station complex where the River LINE passes under the Delair Bridge's eastern approach, platforms were built on both tracks.
