Wiesen Viaduct

The Wiesener Viaduct is the highest stone arch bridge of the Rhaetian Railway and a masterpiece of engineering.

It was built between 1906 and 1909 according to the plans of RhB chief engineer Friedrich Hennings. Construction was supervised by Peter Saluz and Hans Studer, and the scaffolding was crafted by the renowned master carpenter Richard Coray.

Length: approx. 210 m
Height: approx. 88 m
Main arch: 55 m span
Material: Concrete blocks with natural stone cladding

The bridge spans the Landwasser stream in a wild gorge and marks the transition from stone to concrete viaducts.

Today, trains cross the viaduct daily. From the “Sky Walk” footbridge and the Coray viewing platform, you can enjoy a spectacular view of this structure and the surrounding landscape.
