Storebæltsbroen

The Great Belt  Fixed Link  (Danish: Storebæltsforbindelsen) runs between the Danish islands of Zealand  and Funen . It consists of a road suspension bridge  and railway tunnel  between Zealand  and the island Sprogø , and a box girder bridge  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, known as the East Bridge, has the world's third longest main span  (1.6 km), the longest outside of Asia. It was designed by the Danish architectural practice Dissing+Weitling .

The link replaced the ferry service  that had been the primary means of crossing the Great Belt. After more than five decades of speculation and debate, the decision to construct the link was made in 1986; the original intent was to complete the railway link three years before opening the road connection, but the link opened to rail traffic in 1997 and road traffic in 1998. At an estimated cost of DKK 21.4 billion (1988 prices), the link is the largest construction project in Danish history.

Operation and maintenance are performed by A/S Storebælt under Sund & Bælt. Construction and maintenance are financed by tolls on vehicles and trains.

The link has reduced travel times significantly; previously taking about an hour by ferry, the Great Belt can now be crossed in about ten minutes. The construction of the link and the Øresund Bridge  have together enabled driving from mainland Europe to Sweden and the rest of Scandinavia through Denmark, providing an alternative to the significantly longer land route through Finland. Cyclists are not permitted to use the bridge, but cycles may be transported by train or bus.
