Landwasser Viaduct is a railwayviaduct on the Rhätische Bahn over the Landwasser River in Switzerland. It is a 65m high and 136m long six-arched curved single-tracked viaduct high in the Alps. One of its ramps exits straight into the Landwasser Tunnel. The bridge was built by the firm Müller & Zeerleder. Construction began in March 1901 and the first train crossed the viaduct in October 1902.
