Great bridge, with great gravel route that runs underneath

The bridge has a separate bike path. This is lowered by approximately 1.5 m from the roadway. This reduces exposure to the wind. In addition, people with a fear of heights can cycle along the lowered section without having a view of the depths.

Superb arched bridge over the Aulne, similar to the Millau viaduct in its design (same architectural firm). It was built to replace a bridge built in the 1950s, more suited to today's traffic. The construction materials (e.g. sea sand for concrete) affected its solidity.

Among the villages and hamlets which bear witness to the history of the Aulne maritime valley, Le Faou is one of the must-sees. This small town of character brings together beautiful 16th century corbelled houses, a church with a fine Renaissance bell tower and a port. Near the town, the church of Rumengol stands on the remains of a Druid altar.
