Which is the longest combined road and rail bridge in Europe?

The Øresund or Öresund Bridge 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.

The Øresund Bridge is the longest combined road and rail bridge in Europe and connects two major metropolitan areas: Copenhagen, the Danish capital city, and the Swedish city of Malmö. It connects the road and rail networks of the Scandinavian Peninsula with those of Central and Western Europe. A data cable also makes the bridge the backbone of internet data transmission between central Europe and Sweden (and, prior to 2016 also Finland).
