The tunnel remains in use, and can be traversed using a chain boat. Along with the Mauvages tunnel, on the Marne–Rhine Canal, it is one of the last locations in the world where a system of chain towing is still in operation.
It was the longest tunnel in the world until the construction of Biassa II tunnel, La Spezia, Italy.[citation needed]
