The Pont-Canal is a type of aqueduct that carries a canal over a river or valley. It is designed to maintain the water level of the canal while allowing boats to pass underneath. This engineering marvel is often made of stone or concrete and features arches to support the structure. One of the most famous examples of a Pont-Canal is the Pont-Canal de Briare in France, completed in 1896. It spans the Loire River and is notable for its length and height, making it a significant landmark in the region. These structures are essential for maintaining navigable waterways.
