Great Belt Bridge

The Great Belt Bridge (Danish: Storebæltsforbindelsen) is a road and rail crossing spanning the Great Belt strait in Denmark. It connects the island of Zealand, where Copenhagen is located, to the island of Funen, which is itself connected to Jutland on its far side. The strait is a major shipping route, so the design had to allow maritime traffic to pass underneath.

The crossing is not a single bridge but a system consisting of two sections separated by the small island of Sprogø in the middle of the strait. The western section connects Funen to Sprogø, while the eastern section connects Sprogø to Zealand. Road and rail traffic are carried on separate routes.

Eastern section

The eastern section is a suspension bridge carrying road traffic. Its pylons rank among the tallest in Europe, and its main span is among the longest in the world for suspension bridges. Rail traffic does not cross this section of the bridge; instead, a tunnel beneath the strait was constructed for the railway.

Western section

The western section is a box girder bridge made up of prefabricated sections that were transported by barge and assembled at sea. This bridge carries both road and rail traffic on a single deck, unlike the eastern section's design.

Construction and opening

The project was decided in the late 1960s, with construction taking place during the 1980s. The railway line opened first, followed by the road in 1998. Before the bridge was built, people and vehicles crossed the strait by ferry services operating between Halsskov and Knudshoved.

Administration and impact

The crossing is operated by a Danish state company, with costs recovered through tolls charged to passing vehicles. The bridge has substantially reduced travel time between Zealand and Jutland and transformed traffic patterns within Denmark. It is also part of the transport corridor connecting Scandinavia to continental Europe, linked to the Øresund Bridge between Denmark and Sweden.
