Denmark and Sweden Connected by Oresund Bridge

Oresund Bridge — A unique structure, present a modern miracle. It passes through the air, underground and underwater. The 7.8 kilometres-long cable-stayed bridge forms an important part of the fixed link between Denmark and Sweden. From the Swedish city of Malmo to Copenhagen Airport. The Danish capital city, and the major Swedish city of Malmö. It connects the road and rail networks of the Scandinavian Peninsula with those of Central and Western Europe. The crossing of the strait is completed by a 4 km underwater tunnel, called the Drogden Tunnel, from Peberholm to the Danish island of Amager. The term Øresund Bridge often includes this tunnel.

The structure has a mass of 82,000 tonnes and supports two railway tracks beneath four road lanes in a horizontal girder extending along the entire length of the bridge. On both approaches to the three cable-stayed bridge sections, the girder is supported every 140 m or 459 ft by concrete piers. The two pairs of free-standing cable-supporting towers are 204 m or 669 ft high allowing shipping 57 m or 187 ft of head room under the main span, but most ships' captains prefer to pass through the unobstructed Drogden Strait above the Drogden Tunnel. The cable-stayed main span is 491 m or 1,611 ft long. A girder and cable-stayed design was chosen to provide the specific rigidity necessary to carry heavy rail traffic, and also to resist large accumulations of ice.almost 25 million people travelled over the Øresund Bridge: 15.2 million by car and bus and 9.6 million by train. By 2009, the figure had risen to 35.6 million by car, coach or train. Bridge "Oresund Bridge" was opened in 2000. [Source] [First Image credit pfn.photo]

The connection between Peberholm and the artificial peninsula at Kastrup on Amager island, the nearest populated part of Denmark, is through the 4,050 m or 13,287 ft long Drogden Tunnel (Drogdentunnelen). It comprises a 3,510 m or 11,516 ft undersea tube tunnel plus 270 m or 886 ftentry tunnels at each end. The tube tunnel is made from 20 prefabricated reinforced concrete segments – the largest in the world at 55,000 t each – interconnected in a trench dug in the seabed. Two tubes in the tunnel carry railway tracks, two carry roads and a small fifth tube is provided for emergencies. The tubes are arranged side by side.
