The Oresund Bridge ( Danish : Øresundsbroen , Swedish Öresundsbron , Danish-Swedish hybrid spelling Øresundsbron ) is the world's longest cable-stayed bridge for combined road and rail transport. Together with the Drogden tunnel and the artificial island of Peberholm, it forms the Öresund toll connection , which connects the Danish capital Copenhagen with Malmö in Sweden and has thus significantly developed the Öresund region . The border runs 883 meters west of the western pair of pylons and is marked by signs, which are located on the closest sign bridge. The bridge was opened to traffic on July 1, 2000.

The total length of the bridge is 7845 meters. The access to the middle high bridge is via two ramp bridges. The western ramp bridge with a total length of 3,014 meters consists of 22 bridge fields, 18 of which have a span of 140 meters. The 3739 meter long eastern ramp bridge has 28 openings, of which 24 have a span of 140 meters each and four have a span of 120 meters each.

In between is the 1,092 meter long high bridge, the actual Öresund Bridge, with a span of 490 meters. The pylons are made of reinforced concrete , are 206 meters high and measure 9.4 meters × 12.6 meters at the bottom and 2.6 meters × 5.8 meters at the top. The two-storey superstructure has a height of 11 meters and a width of 30 meters. It consists of a reinforced concrete ceiling on top in combination with the steel framework beam below. The four-lane motorway is arranged on the upper deck, and the two railway tracks are located in the truss. Use by cyclists is not permitted. The high bridge has a clear height of 57 meters. A maximum height of 55 meters is specified for ships.

The one billion euro bridge was built in 40 months, around 90% with large prefabricated parts . These were the foundation blocks, the piers and the bridge girders, all of which were made on land and assembled with the Svanen floating crane , which has a lifting capacity of 8,700 tons and a lifting height of 76 meters. Only the two 20,000-ton prefabricated pylon foundations of the high bridge, concreted in a dry dock , were transported to the bridge construction site by catamaran .

The architect was Georg Rotne. It was built by a consortium consisting of Hochtief , Skanska, Højgaard & Schultz and Monberg & Thorsen. The engineering offices involved were Gimsing & Madsen A / S (with the engineer Niels Gimsing), ISC Consulting Engineers A / S, Arup (with the engineers Jorgen Nissen, Klaus Falbe-Hansen), Setec and COWI ( Klaus Ostenfeld ).

Surname

The Øresund Bridge Consortium uses the synthetic name Øresundsbron , which is a hybrid of the Danish and Swedish spelling ("Øresund" is Danish, Swedish would be "Öresund"; "bron" for "the bridge" is Swedish, Danish would be "broen" ). This spelling was partly adopted by the media in both countries, depending on whether the name is taken as a proper name or not.

completion

On the morning of September 14, 1999, a floating crane lifted the last 140 meter long bridge segment. This established a continuous land connection across the Øresund.

At the beginning of March 2003, the Swedish government decided to build a new 11-kilometer railway line from the bridge to Malmö Central station .
