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 crossing Little Pipe Creek 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. The Pennsylvania Railroad acquired control of the F&PL in 1896, and rebuilt the bridge that year as an open deck riveted iron plate under girder bridge and then again in 1902-1903 using steel in the bridge and trestle. 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 circa 1917. Additional work rebuilding the bridge and trestle was performed from 1982 to 1989 by the Maryland State Railroad Administration. In 1991, the bridge was surveyed as part of the Maryland Historic Sites Inventory. As of 2021, the bridge is in rail service, operated by the Maryland Midland Railway.
