Concreting of the Skärholmen Tunnel in Stockholm

From April, division 1 has been working for the Swedish daughter company SBT Sverige on the concreting of the secondary lining of the Skärholmen highway tunnel in the complicated section under Mälaren Lake. Two 40-meter-long tubes will have concrete structures up to 4.5 meters thick, the casting is divided into walls and a vault. The tunnel on the Stockholm road bypass should be completed next year.
