Description 

B&O Railroad Bridge is a 1910 swing bridge in the Grays Ferry neighborhood in Philadelphia, Pennsylvania that carries CSX Philadelphia Subdivision rail lines over the Schuylkill River. It is located upstream from the Passyunk Avenue Bridge. It is also known as CSX's Schuylkill River Bridge. This truss bridge was constructed by the Baltimore and Ohio Railroad in 1910, replacing an earlier bridge.

Modern Rehabilitation

In 1977, the CSX Railroad did engineering studies of the swing bridge mechanisms, and determined that extensive rehabilitation was needed. Although there were Federal Railroad Administration violations and operational difficulties, the rehab project did not start until late 2003, with a completion date planned for May, 2004. There were issues with rail traffic, controlled by CSX, and river traffic, with the US Coast Guard concerned with the fact that during construction the bridge cannot be opened.

The rehabilitation was completed on time in May, 2010, including extensive work on the miter rails, which are mechanisms allowing for disconnecting the steel rails when the bridge is opened, and reconnecting the rails when the bridge is returned to rail traffic.

Bridge is a Pratt through truss. Thank you for the pictures and information on this span.

Perhaps someone more expert than I am can identify what kind of a truss bridge this is, from the photos.
