Pont-canal de Carentan, Navigable aqueduct in Carentan-les-Marais, France.
The Pont-canal de Carentan is a concrete water bridge carrying boats across approximately 615 meters while allowing road traffic on the National Route 13 to pass underneath. The structure consists of two parallel concrete channels with a central section designed to support boat passage and water flow.
The project began in the late 1800s to improve boat traffic between the Vire River and the Canal de Carentan in Normandy. The concrete structure provided a lasting solution to connect inland waterways with coastal routes.
The aqueduct represents the evolution of transportation infrastructure in Normandy, enabling continuous maritime connections between inland waterways and coastal areas.
The structure is best viewed from the adjacent road or nearby viewing areas that offer glimpses of this unusual construction. Visitors should know that active boat traffic means the best views come during early morning or late afternoon light.
The structure was built to carry water about ten meters above ground, allowing both boats and road traffic to coexist at different levels. This required an intricate system to manage water pressure and drainage in order to keep the bridge stable.
