Pont de Pélussin, Railway bridge in Pélussin, France

The Pont de Pélussin is a stone arch viaduct 170.8 m long and 4 m wide, crossing the Régrillon 45 m above the river. It has ten arches of 10.2 m span, six on the Pélussin side and four on the Maclas side, on tall tapered piers. The deck is now paved and closed to rail traffic.

The viaduct was planned in 1913 to extend the Saint-Héand–Pélussin line toward Maclas, and built from 1915 to May 1917. With most French workers at the front, German prisoners and twelve Portuguese labourers worked on the site. The Pélussin–Maclas line opened in May 1917, and the rails were removed in 1934.

Locals nicknamed the little train that crossed it "La Galoche" or "Le Tacot". The rails were lifted in 1934 at the request of the Pélussin town council and the Loire departmental council, and the deck was surfaced for walkers. Today a company runs bungee jumping from the bridge.

The deck is 4 m wide and now paved, so pedestrians can walk across from Pélussin toward Maclas; the rails were removed in 1934. The crossing is exposed, with a low metal railing and lampposts along the top. A bungee-jumping operator uses the viaduct, so expect activity near the deck.

The main arch was planned at 58 m but built at 55 m, and the deck is only 4 m wide. The twelve Portuguese workers hired in 1915 left in May 1916, after which German prisoners were withdrawn from the site in July. The rails were lifted in 1934 at the request of the Pélussin council and the Loire general council.
