At 918 meters, it is the longest navigable aqueduct in the world. . ^( `9 J7 D1 C/ PTVBNOW 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 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 \1 V& T/ |% _$ L% ~) t5 }公仔箱論壇! ~* u) s2 o4 g# T" b4 R* s
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. " F' L9 T! ~& |, {) I( Qtvb now,tvbnow,bttvb6 o4 w( c9 Z8 T9 ^9 o' ]' p$ S8 e* y
