Sitter Viaduct (SGA)
The Sitter Viaduct in Appenzell was built from 1902 to 1904 for the Appenzeller Strassenbahn (ASt).
The viaduct is 296 meters long and consists mostly of brick arches, which are interrupted by two iron bridges. One iron bridge leads over Weissbadstrasse, the other over Sitter and Bleichestrasse. The iron girder over the Sitter is designed as a truss bridge with an arched top chord and a roadway below. It has a span of 49.6 meters. The road overpass over Weissbadstrasse was designed as a girder bridge. The engineer Louis Kürsteiner from St. Gallen was responsible for planning the railway line and the viaduct .
