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.

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%.

The longest motorway tunnel in Germany is the centrepiece of the new A 71 federal motorway from Erfurt to Schweinfurt.
