Sejourne Viaduct, France.

The Séjourné Viaduct which is entirely in granite, is 65m high, 230m long and is composed of a main arch of 30m wide, supporting 16 smaller arches in the Gothic style, above the Têt River. The Gisclard bridge, built between 1905 and 1908, was considered at the time as a real technical revolution. It has a central span of 156m between the axis of the piers and two half spans of 39m. Its deck has a slope of 6% and stands at 80m height. The 32m high piers support pylons of 30m. At the top of the pylons some guys and retaining cables are fixed to the dilatation fitting. These cables are fixed in the mountain. It is the first bridge of a new generation resolving the load bearing problem the railways were having.

The Little Yellow Train also known as the Le Petit Train travels on the bridge.
