A milestone for the Koralm railway line from Graz to Klagenfurt: the double-track tunnel with a length of 1.7 km forms the centrepiece of this construction section.
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.
The Henndorf bypass lead to a noticeable relief of traffic congestion. Centrepiece of the bypass is the double lane 2,150 meters long road tunnel, which is now used by approx. 20,000 vehicles per day.
