Saint-Nazaire Bridge

Highlight • Bridge

The longest bridge in France! And who, in reality, has never been baptized 😁. My cycle lane is rolling and wide enough, but, be careful, the danger comes mainly from debris on the side of the road (screws, plastic, metal and plastic parts...), so be careful!! Or, use the shuttle available (part of the year) located at the port of Penhoët, St Nazaire side or in the car park at the foot of the bridge, St Brevin side

Loire estuary at the Pont de Saint-Nazaire

Highlight • Bridge

The Saint-Nazaire Bridge (French: Pont de Saint-Nazaire) is a cable-stayed bridge crossing the River Loire between Saint-Nazaire and Saint-Brevin-les-Pins on the west coast of France. The bridge is located at the mouth of the Loire and the Atlantic Ocean. The bridge, built in 1974, was opened to traffic on October 18, 1975 and was then the cable-stayed bridge with the world's largest span (Wikipedia).

Carrelets de La Grande Ville

Highlight • Other

La Grande Ville is a hamlet of Saint-Brevin along the Loire estuary, with a long beach characterized by the traditional fishing piers extending far into the water. Here a parking area with restrooms and picnic table is a trailhead for exploring the practice while taking a break along the waterfront biketrail.
