| At high speed through the heart of Europe  Construction of the New Rail Alpine Crossing project with participation by Leister represents a further step in regard to Switzerland's integration in the growing European high-speed network. The core is the Gotthard base tunnel, which at 35.4 miles will be the longest rail tunnel in the world. It will comprise two single-track tunnel tubes. Construction is simultaneously in progress on five partial sections of different lengths, so as to optimize the construction time and costs. The costs for this gargantuan project are estimated to be around $ 10.8 billion. The construction time will total 20 years. The historic breakthrough of the tunnel occurred on October 15, 2010 and the grand opening is planned for 2016.write your comments about the article :: © 2011 Construction News :: home page |
