It only needs to be designed to withstand the weight of the water! ( e6 @- }- P8 i+ E0 i
Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded8 M: @! @" M V9 T3 c V* V5 _ ' w- \# U" j!

The Magdeburg Water Bridge is a navigable aqueduct in Germany that connects the Elbe-Havel Canal to the Mittelland Canal and allows ships to cross over the Elbe River. At 918 meters, it is the longest navigable aqueduct in the world. 8 {5 n+ ?. I$ B% n+ \4 Z6 H! Y5.39.217.77:8898The Elbe-Havel and Mittelland canals had previously met near Magdeburg but on opposite sides of the Elbe Ships moving between the two had to make a 12-kilometer detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sailing downstream on the river, before entering the Elbe-Havel Canal through Niegripp lock. Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo. 8 h# k# N9 J! \2 P5.39.217.77:8898. m' q3 v" Z" z i, A
Construction of the water link was started as early as in the 1930s but due to the World War 2 and subsequent division of Germany the work remained suspended till 1997. The aqueduct was finally completed and opened to the public in 2003. , t O% g5 f9 L. T# _: t
