The Seudre Bridge at La Tremblade

The Seudre Bridge at La Tremblade or the Seudre Viaduct is a bridge located between the towns of La Tremblade and Marennes, which spans the Seudre estuary and faces the island of Oléron. It connects Royan to the island of Oléron, or Marennes, and Port des Barques. It measures over 1000m in length and 20m in height.

It was built in 1972, and spans La Seudre near its mouth, passing over Port-a-sec. From the Pont de La Seudre, one can see the bridge of the island of Oléron, the port of La Grève, and the bell tower of the church of Marennes. To access the foot of the bridge, it is useful to follow the signs port-a-sec.
