Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loadedtvb now,tvbnow,bttvb- J, H6 o+ e/ r' P $ a7 p" W8 @! d) Ctvb now,tvbnow,bttvb ' O3 l& a& E, ]# n1 hTVBNOW 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 Incredible Magdeburg Water Bridge in Germany 3 ~ [9 X6 Y- i5 IThe 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.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。" m2 C6 {) V4 j0 J3 l' `
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. 6 A# L* J3 N" J9 L: q% _. Q9 T0 f3 x
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. ) Y& m( j$ F4 ~: q! J+ |8 {7 ^ y公仔箱論壇 0 Z2 P) ~+ v9 L# j0 o3 y!
