Solis Viaduct

Geschichte

The Solis Viaduct is a single track eleven-arched limestone railway viaduct. It spans the Albula east of the hamlet of Solis, in the canton of Graubünden, Switzerland.Designed by the engineer Hans Studer, it was built in 1902 by Munari, Cayre und Marasi for the Rhaetian Railway, which still owns and uses it today. One of the most important structures on the World Heritage-listed Albula Railway, it is high, long, and has a main span of.LocationThe Solis Viaduct forms part of the Albula Railway section between Thusis and Tiefencastel, and is at the mark from Thusis. East of the viaduct is the Stausee Solis.DescriptionThe limestone-built viaduct was conceived by Hans Studer as the first stone arch bridge in Switzerland to be designed in accordance with the elasticity theory. That choice of design allowed the use of a parabolic arch, and thus a very slim form of construction. Building costs could thereby be limited to 125,000 Swiss francs at 1902 prices.

"Der Soliser Viadukt ist eine Eisenbahnbrücke östlich des Dörfchens Solis im Schweizer Kanton Graubünden. Er ist Teil der Eisenbahnlinie von Thusis nach Filisur der Rhätischen Bahn."
