ADT (Average annual daily traffic): 56 000, The tunnel is an approx. 820 m long (twin tunnel), without on or off ramps. Varies from 2 — 3 lanes. Southbound there is an unused and closed ramp lane. The tunnel is primarily a rock tunnel, with a concrete part to the north and some at the southern end. There is a lot of crossing railway infrastructure in the area.
— reinforcement in the southern end of the tunnel for approx. 40 m in both tunnel directions, as well as in the unused ramp lane,
— rehabilitation of the tunnel, with replacement of technical equipment, construction of 2 new mechanical rooms, construction of a pumping station and sedimentation basin for management of tunnel wash water, traffic safety measures, block leaks, fire prevention and concrete rehabilitation.
The works are planned to be carried out with complete closure of one lane at a time in the tunnel and some night works.
The tunnel opened the northbound lane in 1987 and the southbound lane in 1989, and currently has an ADT of approx: 56 000. To the south, the tunnel ends on Lodalsbrua [Lodals bridge], that is further connected to Ekebergtunnelen [the Ekeberg tunnel], that is part of the Operatunnelen [the Opera tunnel].

— rehabilitation of the tunnel, with replacement of technical equipment, construction of 2 new mechanical rooms to replace the current mechanical room, construction of pumping station and sedimentation basin for management of the tunnel wash water, traffic safety measures, block leaks, fire prevention and concrete rehabilitation.
The works are planned to be carried out with complete closure of one lane at a time in the tunnel. It will be possible to carry out preparation works of a night in a period before the 24 hour/day closure period. The technical buildings and sedimentation basin works in the open air zone are planned to be implemented during the daytime.
