Langwieser Viaduct

The Langwieser Viaduct crosses the Plessur River with a reinforced concrete structure extending 284 meters in length and reaching 62 meters in height.

Built between 1912 and 1914, the viaduct marked a significant engineering advancement as the first railway bridge constructed entirely from reinforced concrete.

The structure holds recognition as a class A Swiss cultural property, representing early 20th-century engineering innovation in the Canton of Graubünden.

The single-track railway bridge connects Chur to Arosa, serving as an essential transportation link in the Rhaetian Railway network through mountainous terrain.

The construction process required 7,469 cubic meters of concrete, 250 tons of steel, and 800 cubic meters of wood for temporary support structures.
