The Oresun Bridge (Danish Øresundsbroen, Swedish Öresundsbron, joint hybrid name Øresundsbron) is a combined two-track rail and four-lane road bridge across the Oresund strait. The bridge-tunnel is the longest combined road and rail bridge in Europe and connects the two metropolitan areas of the Oresund 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 Oresund Railway Line. The bridge is the longest border crossing bridge in the world.
