Road infrastructure Tube 2 of the Karavanke motorway tunnel

In June 2016, a national spatial plan was adopted for the construction of a second tunnel tube measuring some  3,530m in length, along with the missing part of the motorway immediately approaching the tunnel and the existing toll station. 

After re-routing traffic to the newly built tunnel tube, where traffic will run two ways, the older tube will be thoroughly reconstructed.  When both tubes are put into service, traffic flow will increase substantially through the tunnel, which in seasonal rush hours represents a bottleneck and causes congestion on both the Slovenian and Austrian sides.

The Slovenian-Austrian Karavanke tunnel is the only single-tube tunnel in the Slovenian motorway network.
