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 / u5 l* a; P; |% [# M5.39.217.77:8898 % Y" L% k; I) tTVBNOW 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。! X5 C* B! {+ B4 g' I. m( D) a The Incredible Magdeburg Water Bridge in Germany ; v8 s! u" P7 b" K5.39.217.77:8898The 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, M* t+ P5 a, P( I- P
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. 3 U, t0 }5 [+ \: b8 |7 E$ A: H7 o5.39.217.77:8898) P7 l" ? |6 D3 M
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. + v. P6 Q$ \) F!
