Built by master mason Soloman Townsend, the bridge spans 110 feet across the fast-flowing AuSable River.
A heavy rain and flooding in the spring of 1842 created turbulence in the river and undermined the project. The stone of the partially completed arch, the falsework, and the rubble fill all tumbled into the river with a force reported to have been felt five miles away. But Townsend persevered and the bridge was completed in 1843. It has since carried traffic continuously and is one of the oldest such bridges in the US.
One of a group of three bridges in this village collectively designated a Historic Civil Engineering Landmark by the American Society of Civil Engineers. All three are individually listed on the National Register of Historic Places.
