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. * N7 A, |: x) iThe 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. 4 @4 l- X; v$ Z4 b!

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. 4 E: I( q+ ~" r: r7 d7 u$ O' w 9 m* Q0 T/ w2 U- U; v ! @( |1 G$ t" z6 u2 W$ |+ @$ l! h8 nTVBNOW 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。[attach]1486500[/attach] + l* O, Y( {! s) G4 M5 \[attach]1486501[/attach] , f, H: A4 K9 k: i公仔箱論壇[attach]1486502[/attach] / {: a% C4 J$ b- w公仔箱論壇[attach]1486503[/attach] 3 l4 m; L!
