Final Breakthrough Koralmtunnel

On June 17, 2020, the last breakthrough in the north tube of the 33 km long 2-tube railway tunnel took place in construction lot KAT 3. After its completion in 2025, the journey time between Graz and Klagenfurt will be reduced from 3 hours to 45 minutes.

We congratulate the whole team and especially all the employees of Geodata, who have made the perfect breakthrough by their excellent work as those who were responsible for the tunnelling survey!
