Casselman River Bridge State Park is a 4-acre parcel located east of Grantsville in Garrett County on U.S. Route 40. Erected in 1813, and still standing as a picturesque relic of Maryland's early transportation history, the Casselman River Bridge, with its 80 foot span, was the longest single span stone arch bridge in the world during the era of the National Road.
The arch caused skeptics to predict the bridge's collapse once construction was complete and the supporting timbers were removed. The skeptics were wrong, however, as the bridge stood, serving as an important link on the National Road from 1813 to 1933.
