It lies along the Pyhrn Autobahn and it is 8320 m long.

The tunnel was in part built as an alternative route from Graz to the Murau District and the Murtal district, shortening the trip by about 20 minutes.

Currently the tunnel has only one tube with oncoming traffic.

The speed limit is 80 km/h and it has a toll of 10 euro.

Both tubes will definitively open in 2019 according to the project plan.
