The new Lötschberg Base Tunnel

The new Lötschberg Base Tunnel – Record performance on a millenium project, Switzerland ( youtube soundtrack below )

Look up Lötschberg in an atlas and it can't be found... because Lötschberg itself does not exist. Lötschberg is the name of the Alpine crossing between the Kandertal valley in the canton of Berne and the Lötschental valley in the canton of Valais. Nowadays Lötschberg is mostly associated with the new Lötschberg Base Tunnel, a railway tunnel from Frutigen to Raron, to which PORR also made a significant contribution. With a length of 34.6 km, it is not only one of the longest tunnels in the Alps, but also in the world. As part of the "European Corridors 24" (Rotterdam-Genoa) and the new transalpine railroads from the NEAT project, it is the second most important Alpine passage in Switzerland after Gotthard.
