The Roppen tunnel between Innsbruck and Landeck in Austria was made safer by the construction of the second tube. The 5,069 meter long tunnel was driven conventionally.
The long-expected bypass in the Swabian town of Darmsheim will ensure an improved quality of life, since HGV traffic with approx. 23,000 vehicles will not pass through the town in future.
A double-lane motorway tunnel with a length of approx. 3 km forms part of the new motorway section of ‚Route du Nord' in the biggest infrastructure project in Luxembourg. The two tubes were carried out with an incline of nearly 5%.
