    The Øresund or Öresund Bridge
    The Øresund or Öresund Bridge (Danish: Øresundsbroen [ˈøːɐsɔnsˌbʁoːˀn̩]; Swedish: Öresundsbron [œːrɛ²sɵnːdsˌbruːn]; hybrid name: Øresundsbron) is a combined railway and motorway bridge across the Øresund strait between Sweden and Denmark. The bridge runs nearly 8 kilometres (5 miles) from the Swedish coast to the artificial island Peberholm in the middle of the strait. The crossing is completed by the 4-kilometre (2.5 mi) Drogden Tunnel from Peberholm to the Danish island of Amager.

    1 March 23, 1991 sign an agreement Sweden and Denmark sign an agreement to build a fixed link across Øresund.
    2 September 16, 1993 Work begins Work begins on the Danish landworks which comprise 9 km motorway and 18 km railway.
    3 August 1995 coast-coast link Work on the coast-coast link begins with dredging operations in Øresund.
    4 April 1, 1997 two foundations are towed The first of the two foundations for the high bridge pylons are towed from Malmö to the bridge alignment and lowered into a 17 m deep trench excavated in the sea bed.
    5 August 8, 1997 20 tunnel elements are towed The first of the 20 tunnel elements are towed from the factory at Copenhagen’s North Harbour to Drogden where they are lowered into the dredged tunnel trench.
    6 March 16, 1999 tunnel is completed The tunnel is completed and the first vehicle drives through it.
    7 August 14, 1999 final bridge section is placed in position As the final bridge section is placed in position, the link between Denmark and Sweden becomes a reality.
    8 December 1, 1999 final section of the railway is placed in position The final section of the railway between Copenhagen and Malmö is placed in position.

    The Øresund Bridge is an approximately 16 km long road and rail link between Sweden and Denmark. It consists of three sections: a bridge, an artificial island and a tunnel. The bridge accounts for half the length of the link (approx. 8 km) with the two 204 m high pylons supporting the 490 m long bridge span across the Flinte channel. This design is known as a cable-stayed bridge. On the bridge, the railway and motorway run on separate levels with the railway on the lower deck and vehicle traffic on the upper deck. Most of the bridge structures – the bridge piers and bridge spans – were built on land and subsequently towed out to the bridge alignment by a large floating crane. Only the pylons were cast in situ. Linking the bridge and tunnel, the man-made island of Peberholm, where the railway and motorway run The link parallel to each other, is neighbour to the natural island of Saltholm further to the north. 4 km long, Peberholm was constructed from the material dredged from the Øresund seabed to accommodate the bridge piers and the tunnel. Peberholm was built to enable traffic to pass between the bridge, where rail and vehicle traffic run on two levels, to the tunnel where traffic runs on the same level. The 4 km immersed tunnel was built by concrete elements cast on land and subsequently towed out and lowered into a trench dredged in the Øresund sea bed.
    The project has a global demonstration effect on the marine environment and ecosystem.

    1 The project is composed of bridges, tunnels and man-made islands, which are complex. The sea-crossing bridge is near Copenhagen Airport, and the engineering technology is very difficult.
