Lorraine railway viaduct

The Lorraine railway viaduct is a reinforced concrete structure spanning approximately 1,100 meters (3,600 feet) over the Aare valley with four parallel tracks running across it. A series of repeated arches supports the entire structure, distributing weight evenly across the river crossing.

This bridge was completed in 1941 to replace an older crossing and handle growing rail traffic on the Olten-Bern line. The project was part of a larger expansion of the rail network connecting central Switzerland during that era.

The viaduct carries the Lorraine name, referencing the French region, and reflects Switzerland's rail connections with its western neighbors during the mid-twentieth century. Locals and travelers know it as a landmark that shaped how people could move between regions.

The best views of the viaduct come from riverside paths along the Aare or from the train itself as it crosses the bridge. The location sits north of Bern's main station and is accessible by rail on multiple train lines.

When it opened in 1941, this viaduct held the record as Europe's longest railway bridge of its kind, showcasing Swiss engineering innovation. This historical achievement is often overlooked despite reflecting the technical ambitions of the era.
