Viaduc de la Roizonne

The Viaduc de la Roizonne spans 260 meters across the landscape and reaches a height of 110 meters with its semicircular main arch.

The railway bridge, completed in 1916, demonstrates the engineering methods of architect Paul Séjourné through its design with four smaller arches above the spandrels.

The structure represents a period of French railway expansion and technical advancement in bridge construction during the early twentieth century.

Located two miles east of La Mure, the viaduct serves as an essential connection point in the regional transportation infrastructure of Rhône-Alpes.

The bridge stands among four other high bridges in the La Mure area, creating a concentration of notable engineering structures within a small geographic area.
