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. Officially named the East Bridge, the suspension bridge was designed by the Danish firms COWI and Ramboll. It has the world's fifth-longest main span (1.6 km (1 mi)), and the longest outside Asia. At the time of the opening of the bridge it was the second longest, beaten by the Akashi Kaikyō Bridge opened a few months previously.
