Casselman River Bridge - 1813 Summer Morning
When this 80-foot span was erected in 1813, it was the longest single span stone arch bridge in the United States. Skeptics predicted that the bridge would collapse once the supporting timbers were removed - yet the bridge stood, serving as an important link on the National Road from 1813 to 1933.
