It only needs to be designed to withstand the weight of the water! 5.39.217.77:88985 B7 P- H g6 d3 `4 J A3 O+ t' c
Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded公仔箱論壇/ W) _8 [1 ^ n/ e4 z1 Z & l9 o* j, a# g' q& _4 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。3 @! Z9 i9 v- M& h The Incredible Magdeburg Water Bridge in Germany 4 }3 w6 Y+ R. X' i公仔箱論壇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. / Z# H- Z" s+ g5.39.217.77:8898The 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. tvb now,tvbnow,bttvb, }* p& R( M4 Y; L2 g! 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. $ q) O: F9 |8 r
