The Brusio spiral viaduct (or Brusio circular viaduct; Italian: Viadotto elicoidale di Brusio, German: Kreisviadukt Brusio) is a single-track nine-arched stone spiral railway viaduct on the Bernina Railway. It was opened on 1 July 1908.
A key structure of the World Heritage Site-listed Bernina Railway, it is located near Brusio, in the Canton of Graubünden, Switzerland, and was built to limit the railway's gradient at that location within its specified maximum of 7%.[3] It is considered to be one of the architectural highlights of the Rhaetian Railway.[4][5]
