At 918 meters, it is the longest navigable aqueduct in the world. 0 \' _- T# t2 V4 |* f: A+ d1 `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. % o- c# k' b5 f/ Q: X.

The aqueduct was finally completed and opened to the public in 2003. 4 c0 o& v( S0 W: D+ ~, o X公仔箱論壇 8 n! ~0 ^' i!
