This is a channel-bridge over the River Elbe and joins the former East & West Germany, as part of the unification project. Overall length 918 m (690 m over land and 228 m over water),trough width 34 m, depth of water 4.25 m, maximum span 106 m, constructed with about 68,000 cubic meters of concrete and 24,000 metric tons of steel, construction began in 1997 and concluded in 2003.
With the reunification of Germany and the following establishment of major projects in transport tracks the Water Bridge again became a priority. Construction began in 1997, and after six years and around half a billion euros, the water bridge now connects Berlin's inland harbour with the ports along the Rhine river. The huge tub created to transport ships over the Elbe took 24,000 metric tons of steel and 68,000 cubic meters of concrete to build.
Excellent piece of engineering, isn't it impressive?
