New tunnel opens for traffic in Gothenburg

The Marieholm Tunnel is additional crossing over the Göta Älv which will relieve pressure on the congested Tingstad Tunnel. A further river crossing for cars and lorries will make the road system less vulnerable to delays. All major motorways within Gothenburg will use the new Marieholm Tunnel thus reducing disruption on local roads.

The tunnel connects Hisingen and the port of Gothenburg with central Gothenburg and the rest of Sweden and will facilitate traffic in Gothenburg. The connection is one of many pieces of the puzzle that make it possible for Gothenburg to cope with today’s and tomorrow’s traffic challenges.

TFIP has been involved in the project as an advisor in installation to ZÜBLIN and supported STRABAG in the design.

The connection consists of:

  • The south Marieholm bridge; a new railway bridge with a pedestrian and bicycle path over the Göta River
  • The Marieholm tunnel, which is a new road tunnel under the river.
  • In connection with the tunnel, two new traffic locations on several levels have been built.

The 500 meter long Marieholm tunnel will increase accessibility to the Port of Gothenburg, Norra Älvstranden and the western Hisingen industries. The Marieholm tunnel was built with the Göta Älv submersible tunnel technology, approximately 600 meters north of the Tingstad tunnel. It consists of three joined parts (named Göta, Tina and Marie) and weighs 250,000 tons (as much as 1,000 blue whales). The tunnel is about 500 meters long. The roofs of the three parts are 7 meters below the river surface and the road surface is 14 meters below the water surface. The tunnel consists of two tunnel pipes with three lanes in each direction.

The Marieholm tunnel will relieve the Tingstad tunnel, which was built almost 50 years ago when the traffic volume was completely different. The tunnel was originally dimensioned for 80,000 vehicles per day. Today, 125,000 vehicles pass through the tunnel every day and traffic continues to increase as the city grows. The Tingstad tunnel will be renovated during 2022-2023. TFIP looks forward to participating in renovations and contributing our specialist knowledge in technical installations. During the renovation, troughs/entrances will be strengthened, collision protection and fire protection will be improved. Most of the technical installation such as traffic systems, lighting, emergency lighting and emergency evacuation will also be replaced. Two deposition reservoirs will also be constructed for purification and sedimentation of the stormwater that enters the tunnel. The renovations have been planned for a long time and can be carried out thanks to the Marieholm tunnel being in place.
