Glenwood B&O Railroad Bridge

The Glenwood B&O Railroad Bridge is a truss bridge in Pittsburgh, Pennsylvania, which carries Allegheny Valley Railroad's W&P Subdivision over the Monongahela River.

The span was constructed in 1884 and upgraded in 1915. It served the busy Wheeling division of the Baltimore & Ohio Railroad, which in 1928, operated an average of 19 freight and 12 passenger trains across the structure each day. After B&O was absorbed into CSX Transportation, this company ran local freight trains across the bridge; the short line Allegheny Valley Railroad has a long-term lease to manage this structure, which serves a route between its headquarters in an adjacent rail yard and Washington, Pennsylvania.
