For this crossing a tunnel has been constructed with a total length of 1.500 m accommodating 2x3 road lanes and a service / escape duct. The tunnel is suited for the transport of dangerous goods (category I).
The tunnel was constructed to replace the bridge on motorway A15 that contained a movable part that opened 8.000 times a year to allow the passage of the sea-vessels.
The enclosed part of the tunnel is 1.100 m. The section below the canal and the deep sections of the approaches are constructed using the immersed tunnel technique, with six elements of 115 m.
