This Amazing Bridge That Turns Into An Underwater Tunnel Between Denmark And Sweden

A Very long bridge, was designed by the architect George K.S. Rotne from Danish, was open on July 1, 2000 after only five years of construction. The Øresund was built to connects the Danish capital of Copenhagen to the Swedish city of Malmö with nearly 8 km long, through an artificial island into Drogden tunnel about 4 km long that constructed from material in the seabed.
This brigde is not just an award-winning double-track railway and motorway, but it is also four dark fiber network cables too. It take about 35 minutes for the people’s journey between Malmö and Copenhagen by train. By the way it is a place that the dreadfully sea-sick people can reach Sweden (or Denmark) in their own comfortable car.
