The action to be taken will free the Mont of the stranglehold
of the surrounding salt marshes. Through the combined forces of the sea and the River Couesnon, the sediment will be flushed out to sea and the vicinity of the Mont will be clear of salt
marshes for a long time to come. Once the new dam is up and running, it will take just two years to clear half of the 3 million m3 of sediment by natural means and 8 years to reach 80% of that target.
Demolition of the current parking areas will restore 15 hectares of sands to their
natural state. The landscape will fully recover its marine dimension.

A masterpiece of our world heritage, the Mont-St-Michel is now the number one
tourist attraction in France outside Paris. Each year, over three million visitors come from all over the world to admire it. However, tourist facilities are no longer up to the high standard either of the place itself or of the publics expectations .
The project has sought to make the crossing to the Mont St-Michel from the mainland a pleasurable experience. This meant setting up not just a starting point, a place to board and to alight, but also a ride to relate the different stages of the scenery as it changes along the way.
