Railroad viaduct BN over the Saane, Railway viaduct in Ferenbalm and Mühleberg, Switzerland
The Saane Viaduct near Gümmenen carries the Bern–Neuchâtel railway over the Saane valley on 27 arches of Jurassic limestone, each with a clear span of only 10 m. A steel truss bridge crosses the river itself, and an earth dam forms the western end. The structure is over 650 m long.

The structure was built in the early 1900s and displays the craftsmanship typical of that era. Visitors can observe how steel and stone were joined together and recognize the design language of that period's engineering.
The viaduct can be observed well from several spots along the riverbank and is easily accessible. Daytime visits work best so you can see the structure clearly and watch the water below.
The viaduct remains in daily use and regularly carries both passenger and freight trains across its span. Visitors can often watch trains moving over the structure built in 1901, showcasing how well the construction has lasted over time.
