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 centrepiece of the 125 km long, double-track high-speed line between Graz and Klagenfurt is simultaneously the key project for the Baltic-Adriatic-Corridor. The Koralm Tunnel improves the traffic link between Graz and Klagenfurt.
During extension of the Pyhrn motorway, the Gleinalm Tunnel is provided with a second tube. This makes the motorway safer, since there will be no oncoming traffic in the tunnel.
