Gmündertobelbrücke

About

The Gmündertobelbrücke (literally "Gmündertobel Bridge") in the Swiss canton of Appenzell Ausserrhoden connects the Steinerstrasse (Route 463) between the towns of Stein and Teufen across the gorge of the Sitter river. It is located a few kilometers south of the city of St. Gallen, but is not part of the St. Gallen bridge trail because it is not located in the Canton of St. Gallen. The bridge is an important example of early concrete arch bridges and, when completed in 1908, was briefly the longest concrete arch bridge span in the world. It is classified by the Swiss government as a cultural property of national importance.
