The Øresund or Öresund Bridge is a combined two-track rail and four-lane road bridge-tunnel across the Öresund strait. It is the longest combined road and rail bridge in Europe and connects the two metropolitan areas of the Öresund Region: the Danish capital of Copenhagen and the Swedish city of Malmö. The international European route E20 runs across the bridge and through the tunnel via the two lane motorway, as does the Öresund Railway Line. The bridge is the longest border crossing bridge in the world, but due to the Schengen Agreement, there are no passport controls. However there are frequent random customs control checks at the toll booths on the Swedish side for those entering Sweden, but not when entering Denmark.
The bridge has one of the longest cable-stayed main spans in the world at 490 metres (1,608 ft). The height of the highest pillar is 204 metres (669 ft). The total length of the bridge is 7,845 metres (25,738 ft), which is approximately half the distance between the Swedish and Danish landmasses, and its weight is 82,000 tonnes. The border is located 2.5 km (1.6 mi) from the western end and 5.3 km (3.3 mi) from the eastern end of the bridge. On the bridge, the two rail-tracks are beneath the four road lanes. The bridge has a vertical clearance of 57 metres (187 ft), although most boat traffic across Oresund still passes over the Drogden strait (where the tunnel lies). The bridge's architecture is by Georg Rotne, with structural design made by Arup.
