Lorraine railway viaduct

The Lorraine railway viaduct, or Lorraineviadukt, is a railway viaduct in the Swiss city of Bern. It carries the Olten–Bern railway across the River Aare immediately to the north of Bern railway station. The Lorraine road bridge is adjacent.

The bridge was built in concrete by the Swiss Federal Railways to replace the aging Rote Brücke and opened in 1941. It is 1092 m in length and was the longest four-track railway viaduct in Europe at the time of construction.
