Tunnel de Champel

Carouge (Geneva), Schweiz

The Tunnel de Champel is part of the new CEVA rail link con­necti­ng Geneva’s main Cornavin station with the Annemasse region in France. The two-lane rail tunnel runs just a few meters below the heavily developed urban neigh­bor­hood of Plateau de Champel. Due to the additional challenging geo­logy caused by glacial de­posits, the rock also had to be stabilized with pipe arch protection during the con­struc­tion period.
