The Oresund Bridge 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, as does the Oresund Railway Line.
The Oresund Bridge is the world's longest single bridge carrying both road and railway traffic. In the design full advantage was taken of repetition by composing the major part of the bridge of identical spans. The high bridge with its record-breaking cable-stayed span of 490m is designed to harmonize both structurally and aesthetically with the approach bridges. In the construction phase the on-site activities were completed in just 2 1/2 years due to an extensive use of prefabrication and erection of large units.
