    Ceneri Base Tunnel

    Switzerland

    2006 - 2017
    The Ceneri Base Tunnel (CBT) is set to become the second biggest railway tunnel in Switzerland after the Gotthard Base Tunnel, in Switzerland's Canton Ticino and is part of Swiss AlpTransit NRLA project.
    Together with the Gotthard tunnel, the Ceneri Base Tunnel will offer a faster connection between Zurich and Milan;it will be also an important feeder in the south for the Gotthard Base, easing local train traffic, mainly between the two major cities Locarno and Lugano but also between Bellinzona and Lugano. Travel time on the S-Bahn from Locarno to Lugano should drop from 50 to 22 minutes.
    The Ceneri Base Tunnel is composed of two single-track tunnels, each of them having a length of 15.4 km.
    The length of the entire tunnel and the passage system will be 39.78km, stretching between Vigana and Vezia.
    The estimated investment for the project is Sfr2.4bn ($2.58bn).
Our job references are the tangible result of more than 20 years of international on-site Underground Construction & Mining experience due to a worldwide network of highly trained and  professional Technical Service.
