It only needs to be designed to withstand the weight of the water! 5.39.217.77/ [) D8 J- Q" i5 J
Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded7 Q' l* m! n7 f6 y X8 E( N( ~ 3 k) l: ~& A8 k: f3 D5.39.217.77$ s3 d3 y2 W4 Y+ x0 v- [ b The Incredible Magdeburg Water Bridge in Germany * t3 f5 G/ P0 h' F0 aTVBNOW 含有熱門話題，最新最快電視，軟體，遊戲，電影，動漫及日常生活及興趣交流等資訊。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.tvb now,tvbnow,bttvb2 d+ R& |5 O2 ^
The 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. + a! R, {. Q; q/ _, R. v5 |1 z- p!

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. 5.39.217.77; [+ s) k9 Z: @; r
