SBB-Sitterviadukt

The SBB-Sitterviadukt is a concrete railway bridge that spans across the Sitter River valley, carrying two railway tracks and a separate pedestrian path. The structure connects the area to the main railway network while allowing both train traffic and foot passage across the valley.

The viaduct was built in 1925 to replace an earlier iron bridge that had crossed the valley since 1856. This shift from iron to concrete construction reflects how railway engineering evolved during the early 20th century.

The bridge remains a key part of a railway line that has connected Swiss communities for generations and continues to carry passengers and freight daily. It represents how major transport infrastructure shapes the regional landscape and the rhythm of travel through this area.

The pedestrian path on the southern side of the viaduct is open to walkers and cyclists who want to cross the valley. The best views of the structure come from below or from the riverbank when exploring the surrounding area.

The structure was built entirely from concrete and represented a remarkable engineering achievement for the Swiss railway company when it was completed. The five symmetrical arches are carefully shaped and create the distinctive profile of the viaduct as it spans the valley.
