At 918 meters, it is the longest navigable aqueduct in the world. 1 }3 J2 |8 _# v' ` X' {2 h; }& _5.39.217.77:8898The 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. * K1 R- |. u8 @5 D/ O7 `

The aqueduct was finally completed and opened to the public in 2003. 1 Y0 P x/ X- R公仔箱論壇5 {( M) D: D7 S. W) L! V( |% j: G
