The Øresund Bridge is a combined railway and motorway bridge that connects Denmark and Sweden, spanning nearly 8 km from the Swedish coast to the artificial island of Peberholm in the middle of the strait. The bridge also includes a 4 km Drogden Tunnel from Peberholm to the Danish Island of Amager. Construction began in 1995 and was completed in 1999, with traffic being released in July 2000. The entire project cost approximately €3 billion in 2010 prices. The railway is a significant component of the bridge, with around two-thirds of the traffic using it.
