The 7,884 metre long bridge between Sweden and Denmark includes the world's longest cable-stayed bridge for combined motorway and high speed railway traffic.
The bridge crosses the navigation channel with a main span of 490 metres and two side spans of 160 metres and 141 metres on each side of the main span, and a height of 57 metres above the sea.

The approach bridges towards Sweden and Denmark are 3,739 metres and 3,013 metres, respectively. 

Two-lane motorway

The girder for the cable-stayed bridge is a composite truss in steel and concrete. The concrete top deck carries a dual two-lane mototway with emergency lanes. The lower deck carries a two-track railway.

The approach bridges with 140 metre spans have a two-level composite superstructure with a steel truss incorporating an upper concrete roadway deck and lower steel cross beams with a concrete railway containment.

Artificial islands

The concrete pylons are 203.5 metres high and founded on limestone. Prefabricated caissons are placed at a water depth of approximately 15 metres, and the pylon shafts are cast in place.

Artificial islands were established around the pylons and nearby piers to protect against ship impact.

All caissons, piers and pier shafts were prefabricated on-shore and assembled off-shore.


The contract was a design-and-construct contract, which means that the contractor was responsible for both the basic and the detailed design and construction.

The Skanska-led consortium Sundlink Contractors HB entrusted the basic and detailed design and endorsement of the construction work to the CV Joint Venture COWI and VBB of Sweden with COWI as lead partner.

The bridge was opened for traffic in July 2000.
