The Great Belt Fixed Link (Danish: Storebæltsforbindelsen) runs between the Danish islands of Zealand and Funen. It consists of three structures: a road suspension bridge and a railway tunnel between Zealand and the small island Sprogø located in the middle of the Great Belt, and a box girder bridge for both road and rail traffic between Sprogø and Funen. The "Great Belt Bridge" (Danish: Storebæltsbroen) commonly refers to the suspension bridge, although it may also be used to mean the box-girder bridge or the link in its entirety. The suspension bridge, officially known as the East Bridge, has the world's third longest main span (1.6 km), the longest outside of Asia.
