The Kienberg tunnel with a length of 1.45 km and the Hungerbichl tunnel with a length of 0.53 km are located on the A9 Phyrn Autobahn, north of the Klaus tunnel chain. Both tunnels consist of two two-lane tunnel tubes that are connected by a valley crossing.

The project A09 Phyrn Autobahn Tunnel Kienberg and Tunnel Hungerbichl renovation and adaptation to STSG includes the replacement of the existing control components and the renovation of the electrical system. The electrical equipment runs in several electronics of an operating station and the operating center Kienberg. Several access points are connected to control the free field systems.
The Klaus node was integrated into the tunnel control system with a dirt hopper, a water protection system and several signposts from the state road. Controlling the radar system dynamically adjusts it to the speed in the tunnel.
The fully automatic lighting control for the entrance and passage areas depending on the outside light, the traffic volume and occurring events cover the highest safety standards. In the event of a fire, the tunnel ventilation controls the reliable flue gas discharge to protect the traffic jams.
The special location of the tunnels on the A09, directly between the Klaus tunnel chain and the Inzersdorf-Schön section, required a direct exchange of information between the tunnels. Different technological interfaces were used to implement the higher-level traffic control system over the entire route. Monitoring is carried out centrally by the traffic management center in Ardning.
