Summary

The Little Pipe Creek bridge and viaduct is a 705-foot (215 m) continuous truss bridge with main span and 19 viaduct sections as well as an active railroad trestle south of Keymar, Maryland. Originally constructed by the Frederick and Pennsylvania Line Railroad Company (F&PL). Construction on the trestle began in late 1871, and continued until April 1872. It was rebuilt by the Pennsylvania railroad in 1896 as an open deck riveted iron plate under girder bridge and then again in 1902-1903 using steel in the bridge and trestling. In 1915, the bridge was surveyed as part of the Interstate Commerce Commission's effort to establish freight rates for the Parent railroad. The United States Railroad Administration rebuilt the creek span in the 1917 period. Additional work rebuilding the bridge and trestling was performed in the 1982-1989 period by the Maryland State Railroad Administration. In 1991, the bridge was surveyed as part of the Maryland Historic Sites Inventory.

As of 2013, the bridge is in active rail service, operated by the Maryland Midland railroad.
