At 918 meters, it is the longest navigable aqueduct in the world.tvb now,tvbnow,bttvb3 W' w- v# @; ~, g5 y A6 c
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. 公仔箱論壇( [$ N8 L$ {* e% {0 c$ D

The aqueduct was finally completed and opened to the public in 2003. 4 n& U2 }3 x7 R0 G4 Z/ }5.39.217.77:8898 " Z8 U1 s; N0 Q; e, V8 b ' T$ C) q6 x- Z. t1 z; b[attach]1486500[/attach]5.39.217.77:8898* I9 X# v/ k: N4 S# _& f+ c9 T [attach]1486501[/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。! }3 D' b4 a) ?!
