Switzerland is composed of 60% of the Alps. Therefore it is natural to build tunnels and use the underground space for environmental and energy matters like hydro power plants. This post deals with the big traffic lines through Switzerland.
The two main connections of the Genoa - Amsterdam axis are the Gotthard Base Tunnel and the Loetschberg Base Tunnel. Those tunnels are built to reduce the heavy goods transports on the roads and to put them on the rails.
