Casselman River Bridge State Park

Casselman River Bridge State Park is a 4-acre parcel, popular for picnicking, fly fishing and photography. When the 80-foot span was erected in 1813, it was the longest single-span stone arch bridge in the United States and served as an important link on the National Road from 1813 to 1933. Although the bridge no longer carries vehicular traffic, it is open to pedestrians and is accessible for disabled visitors.
