Stone Bridge

The Stone Bridge crosses the Conemaugh River using seven stone arches arranged in a continuous span of approximately 428 feet. The structure carries four railway tracks for active Norfolk Southern Railway operations.

Built by the Pennsylvania Railroad between 1887 and 1888, the structure survived the catastrophic Johnstown Flood of 1889 despite debris damage. The bridge's survival through this major disaster established its reputation as a robust engineering work.

The bridge displays monthly color changes to recognize different causes and occasions in the community. These visual signals create a connection between the structure and local residents through its role as a landmark for shared causes.

The bridge remains in active railway use and is regularly maintained to ensure safe operations. Visitors can view the structure best from the surrounding riverside areas near the base.

Engineers chose stone construction during a period when iron and steel were dominant in bridge building, making this one of the few remaining skewed stone arch bridges. This decision reflected an unusual preference for traditional methods at that time.
