The Sitter Viaduct (also known as the Kräzern railway bridge ) is a railway bridge operated by the Swiss Federal Railways (SBB) over the Sitter near St. Gallen . It belongs to the St. Gallen – Winterthur railway line .

Sittertobel with the first, from Saint Gallo-Appenzell railways built railway viaduct. In front the Kräzernbrücke for road traffic, in the back the Sitter Viaduct of the former Bodensee-Toggenburg Railway .
The Sitter Viaduct from 1925

The first railway bridge was built between 1853 and 1856 by Louis Gaspard Dollfus from Mulhouse . On this building he worked with the engineers Carl von Etzel , Friedrich Wilhelm Hardmann, Reinhard Lorenz and Adolf Naeff. The proposal for a wrought iron arch bridge came from Carl von Etzel. It was the first wrought-iron and cast-iron railway bridge on the European continent. The Britannia Bridge served as a model for the construction . The bridge consisted of a lattice girder supported on three 48 meter high cast iron pillars. The structure was 165 meters long and the roadway was 61 meters above the water level. The bridge was first used by a locomotive on March 16, 1856 (Palm Sunday), in the morning at 6 a.m., on the occasion of an inspection trip. The route and thus the bridge was officially opened on Easter Monday, March 24, 1856, with the consecration being carried out by the Bishop of St. Gallen.

The SBB replaced the first bridge in 1924/25 as part of the double-track expansion. Now five stamped concrete arches clad with natural stone (there is a sixth arch in an abutment) each with a 30 m span and a 17 m wide end arch bridge the Sitter at a height of 63 m.

It is not far from the Südostbahn bridge and has a footbridge and a cycle path on the south side.

The St. Galler Brückenweg leads past the viaduct.
