The Brusio spiral viaduct is a single-track nine-arched stone spiral railway viaduct on the Bernina railway. It was first opened on 1 July 1908.
A key structure of the World Heritage-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%. It is considered to be one of the architectural highlights of the Rhaetian Railway.
