The bridge element is the second longest bridge in Europe at 7,845 metres and connects the Swedish coast to the artificial island of Peberholm. The link is completed by a tunnel of 4,050 metres from Peberholm to the Danish Coast. The tunnel section is necessary to provide passage for large vessels, plus it reduces the risks associated with the nearby Copenhagen Airport.
The majority of the tunnel (3,510 metres) is constructed with precast concrete sections. sunk into a trench on the sea bed.The access tunnels to this central section were bored as true tunnel. On the bridge section, the railway runs at a lower level with the roadway on top. In the tunnel, there are 5 separate passages through the tunnel - two each for the road and railway, plus a section for emergency shelter and evacuation. These five sections are all alongside each other. . Construction of the link began in 1995 and it opened to traffic in 2000. The map marker is placed at the western (Danish) portal of the tunnel. The international boundary is actually in the bridge section, made famous by it featuring in The Bridge, a Nordic thriller TV series written by Hans Rosenfeldt that starts with the discovery of a dead body on the bridge lying across the international border.
