At 918 meters, it is the longest navigable aqueduct in the world.tvb now,tvbnow,bttvb( F3 G5 w- z- t3 d
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. - Z9 u6 c& f/ q( [公仔箱論壇% p0 B, S5 | g5 C' y
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. z* x% K; P% U4 {: o" s
