The Great Belt East bridge




The Great Belt East Bridge is part of a link between Denmark and Sweden. The first design was made in 1965. It consisted of a box girder bridge with two central spans, each 400m in length. These were supported by piers. The idea was that ships sailing in one direction would pass under one span, and those sailing in the other direction would use the other span.

Because ships became larger and larger, this design was abandoned and a new design made in 1973. This had a much wider central span of 780m. This is greater than the limit for box girder bridges – around 500m. At this point even the strongest steel bends under its own weight. So a cable stay bridge was proposed. With cable stay bridges, the decks are built out from each pier until they meet in the middle. The longer the bridge, the more difficult it is to control the movement of the ends when it is windy – 1,000m is about the limit for such bridges.

Construction was further delayed and in the meantime ships grew larger than ever. Experiments showed that large ships could not safely pass each other under the bridge – even with the wider span. The risk of collision was too great. The only alternative was a suspension bridge. A new design was made in 1993 for a suspension bridge with a 1,600m span – at that time the longest bridge in the world. To support such a span, two huge towers, each 254m high, were built. The bridge deck is quite slender – only four metres deep. To prevent twisting in the wind, the deck was specially shaped. The suspension bridge was finally completed in 1998.
