Arch Bridge

Arch Bridge is a road bridge with a single arch that spans the Connecticut River between North Walpole and Bellows Falls. The steel structure connects both banks of the waterway with a flowing curve.

The structure was completed in 1905 and was at that time the longest three-hinged arch bridge in the United States. It represented an important milestone in bridge engineering.

The bridge connects New Hampshire and Vermont and serves as an important link between two New England communities. People use it daily to cross between the two states for work, shopping, and visiting.

The structure carries vehicle traffic on New Hampshire Route 12 and Vermont Route 121 and is easily accessible by car. Pedestrians can also walk across.

The three-hinged design allows the bridge to flex with temperature changes and ground movement without building up internal stress. This engineering feature has helped it last over a century.
