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 ) ]; v+ F: [7 r& Q8 k% C/ r: |5.39.217.77:8898 7 G6 M6 R7 S, d0 C3 w- F7 B 8 u/ N! t& j8 H& z+ d% e0 i公仔箱論壇The Incredible Magdeburg Water Bridge in Germanytvb now,tvbnow,bttvb6 ^5 _3 [6 E4 E9 S
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,bttvb. Q* J$ m1 M; X! ?
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. 0 B* x& n6 c U2 c5 s! z4 eTVBNOW 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。5.39.217.77:88983 t) s! u9 e7 b& ^5 s+ e; g
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. 7 } _# ]5 C. S6 U2 n7 ztvb now,tvbnow,bttvb: v' j. |3 k- T7 g8 L' B
