Magdeburg Water Bridge, Germany

The Germans took over 80 years to build this 918m (3,000 ft) bridge over the Elbe river near the town of Magdeburg. Canal engineers had first conceived of joining the two waterways as far back as 1919, and by 1938 the Rothensee boat lift and bridge anchors were in place, but construction was postponed during World War II. After the Cold War split Germany, the project was put on hold indefinitely by the East German government.

With the reunification of Germany and major establishment of water transport routes made the Water Bridge a priority again. Work started in 1997, with construction taking six years and costing €500 million. The water bridge now connects Berlin’s inland harbour network with the ports along the Rhine river. The aqueduct's trough structure incorporates 24,000 tonnes of steel and 68,000 cubic meters of concrete. The Magdeburg water bridge was opened in 2003
