Salisbury Viaduct, Railway bridge in Somerset County, United States.

The Salisbury Viaduct is a steel bridge that spans across the Casselman River valley, crossing the riverbed below. The structure now serves as a path where visitors can walk and cycle through the natural landscape.

The Salisbury Viaduct was built in 1912 by the Western Maryland Railway for its Connellsville Extension, engineered for two tracks although only one was ever laid. It carried trains until the line was decommissioned in 1975. In 1998, after modification for use as a rail trail, it opened to pedestrians and cyclists as part of the Great Allegheny Passage.

The structure connects communities today through recreational activities on a former railway route. People regularly use it for cycling and walking, giving this place a new purpose in local life.

The viaduct carries the Great Allegheny Passage trail across the Casselman River valley near Meyersdale, so walkers and cyclists cross it on the former rail bed. The deck is exposed to wind and weather, and the surface can be wet or slippery after rain. The trail is open to pedestrians and cyclists only, not to motor vehicles.

This path is part of a larger network for cyclists and walkers that connects different landscapes. Many visitors use it as part of a longer exploration tour through the region.
