The Clécy viaduct - or La Lande viaduct - is a 354 ft (108 m) long and 98.4 ft (30 m) high railway bridge that crosses the Orne valley in the Calvados department. Built in stone according to the plans of the architect Verjat employed by La Compagnie des Chemins de Fer de l'Ouest (The Western Railway Company), it consists of nine arches and allows the passage of a single track out of the two initially planned. Its construction was completed in 1866, seven years before the commissioning of the line linking Caen to Flers via the Norman Switzerland.
