The Birmingham Bridge is notable for the dead end lanes that were originally to be part of a city belt system. The project was canceled and the bridge rerouted. A pedestrian walkway runs along the downstream side of the bridge, ending at steps at the south abutment of the bridge.

On April 2, 2007 large sections of the bridge were shut down for repair. The repair project was expected to finish on November 1, 2007. While the project did not complete on time, by late November all barricades had been removed and all lanes were again open. During the bridge rehabilitation, bike lanes were added along the outer sides of both the northbound and southbound traffic lanes.

On February 8, 2008 the bridge was closed for inspection after a motorist called 911 when the deck dropped several inches. PennDOT indicated that one of the rockers that support bridge beams slipped http://www.philly.com/philly/wires/ap/news/state/pennsylvania/20080208_ap_birminghambridgeclosedforstructuralinspection.html and "feels it is in the best interest of the traveling public to close the outbound lanes at this time and conduct a thorough inspection to ensure the integrity of the structure. http://www.tribune-democrat.com/local/local_story_039102844.html In the early morning hours of Monday, March 3, 2008, the southbound deck reopened for to serve traffic in both directions, cars and buses only. On September 8, 2008, the northbound deck fully reopened and northbound traffic was relocated to it. The inner lane of the southbound deck remained closed, and southbound trucks were still barred from the span.
