It only needs to be designed to withstand the weight of the water! 公仔箱論壇! k; u1 ?+ ~, q/ [; b5 K2 H0 r
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' p8 X; a+ w; M- _, J8 U * c; w6 T! j2 m+ d) G公仔箱論壇TVBNOW 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。8 w' I2 c: H9 T% G: A5 i; d The Incredible Magdeburg Water Bridge in GermanyTVBNOW 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。' I( j4 C- ~2 t1 W' d" R+ U% R& _
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.' k* {3 _. v, V! Q+ T2 C
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. y8 O' G3 C- |2 R: H7 m' W5.39.217.76 # b6 b+ ~0 q5 z' y+ fConstruction 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. 9 F4 w( H5 w: J% X* s/ _ p+ Z; m
