At 918 meters, it is the longest navigable aqueduct in the world.公仔箱論壇6 Y& a( |8 C( s* F; |( a& A
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: e/ ^; i) @) n0 e; q) N
; C3 M# c7 |! \" qConstruction 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. 8 o6 j! [+ E, G8 P7 j5.39.217.77:88984 W8 D. G9 s, [9 u/ G8 U
