The Viaduc de la Semène, officially known as the Viaduc de Pont-Salomon, is actually comprised of two independent, adjacent viaducts. The first, built between 1977 and 1978, is 500 meters long, and the second, constructed between 1999 and 2000, is 505 meters long. Both are made from pre-stressed concrete voussoirs and reach a maximum height of 50 meters, carrying the N88 highway over the Semène river, a railway line, and the D45 road.
While the viaduct itself offers panoramic views from its vicinity, the best appreciation comes from exploring the surrounding Semène valley. Walking along the riverbanks or utilizing the local hiking trails provides various perspectives of the structure against the natural landscape.

The Viaduc de la Semène is situated within the Velay region, which is known for its distinctive geological features.

You can find detailed route information and elevation profiles on platforms like komoot to choose a path that suits your fitness level.
