Koralm Tunnel and New Semmering Base Tunnel: State of Development
The Südbahn represents a significant inner-Austrian railway link and is at the same time a part of the pan-European Corridor VI from the Baltic states to Upper Italy, connecting the Baltic Sea with the Adriatic Sea. Two of Europe’s biggest tunnelling projects are being tackled on this axis: the 32.9 km long Koralm Tunnel passes below the mountain range between Styria and Kärnten and the 27.3 km long New Semmering Base Tunnel will link Lower Austria with Styria (please refer to the news-section with the latest on abrogation of the construction permit on page 8).
