At 918 meters, it is the longest navigable aqueduct in the world.tvb now,tvbnow,bttvb' G- V6 B1 q$ p; g
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. . i$ t0 w+ ?: U4 Y# x公仔箱論壇9 {1 S# }+ _, q# Y v$ R
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. 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。' K: N/ b( j8 m7 N4 M4 n9 ]: r6 Q6 Q
