At 918 meters, it is the longest navigable aqueduct in the world.5.39.217.77:88986 }$ Z3 B/ C# M$ O2 Q
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. 1 b1 d2 ~: g2 s" F1 _* R * `& k) F, B9 k' [& yConstruction 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. ! j' ?! w+ P2 Wtvb now,tvbnow,bttvb ! \- N3 E$ o/ V% h5.39.217.77:8898 / N5 k- T, o& C J4 C* m[attach]1486500[/attach] ( {0 F7 M4 t( v1 T+ P8 H: itvb now,tvbnow,bttvb[attach]1486501[/attach]9 X0 f+ `7 k+ ~8 B# I2 E [attach]1486502[/attach] 9 J+ c( C. \* E9 \4 w5.39.217.77:8898[attach]1486503[/attach]) Y7 x8 o% m6 r* K+ C [attach]1486504[/attach] 6 s' q- {" _* G; f3 x# a& `% w5 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。[attach]1486505[/attach]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。" J; i+ W6 I1 R8 ^
