Hagerstown Road Bridge, Spanning Little Cotoctin Creek at Old Hagerstown Road, Middletown, Frederick County, MD

Significance: The Hagerstown Road Bridge is one of 26 metal truss bridges remaining in Frederick County. In 1978, there were approximately 40, but increased traffic has led to removal of many bridges. The bridge is structurally unusual for its low placement of the lower chord bolt connection. It is otherwise typical of 1920 steel pony truss bridge construction of the Pratt type. The road and crossing are significant as the main 18th century road west from Frederick to Hagerstown, until replaced by the National Pike in the early 19th century.

Survey number: HAER MD-89
