Project description

The tunnel consists of an immersed tunnel section with cut & cover tunnel and open ramp sections at both ends. The immersed tunnel section crosses the Göta Alv river, measures 306 m in length and is made up of 3 tunnel elements of equal length.

The tunnel elements will be fabricated in a construction dock at the Marieholm-side of the crossing, within the alignment of the tunnel. The construction dock has room for a single tunnel element which requires the dock to be used 3 times for the IMT after which the cut & cover tunnel can be realised at that side of the crossing. The tunnel elements will be segmented and will be placed in a dredged trench on a sandflow foundation.
