Casselman Bridge, also known as Casselmans Bridge or Castleman's Bridge, was completed in 1811 and opened for traffic in 1813 to carry the National Road across the Casselman River near Grantsville in Garrett County, Maryland. The bridge and surrounding four acres are preserved as Casselman River Bridge State Park.
The 354-foot-long (108 m) stone arch bridge spans 48 feet (15 m) with a 30-foot-high (9.1 m) arch. It is located 0.5 miles (0.80 km) east of Grantsville, Maryland beside what is now US Route 40 Alternate and was declared a National Historic Landmark in 1964. The bridge was built to aid in the westward movement through the wilderness west of Cumberland. While highway traffic no longer crosses the bridge, it remains in good condition.
Historic markers posted at each end of the bridge read:
Erected 1813 by David Shriver, Jr., Sup't of the "Cumberland Road" (The National Road). This 80 foot span was the largest stone arch in America at the time. It was continuously used from 1813 to 1933.
In the 1940s and early 1950s efforts were made to preserve the bridge. Sections of the bridge had started to crumble and fall apart. The bridge was patched and preserved as well as possible at the time. In 1979 the bridge was inspected structurally and rehabilitation plans were designed by Wallace, Montgomery & Associates, LLP, to help save the structure and return it to its original state.
