The Incredible Magdeburg Water Bridge in Germany: p- y8 u3 z1 ^1 b1 X) X
The Magdeburg Water Bridge is a navigable aqueduct in Germany that connects the Elbe-Havel Canal to the Mittelland Canal and allows ships to cross over the Elbe River. At 918 meters, it is the longest navigable aqueduct in the world./ d2 y* K* V; ~4 u* N
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) [3 E, G9 f! U% g% k8 l4 o9 I* R9 {

The aqueduct was finally completed and opened to the public in 2003. 公仔箱論壇3 Q6 c9 h% r+ Z( E6 z, U. B8 v8 Y% ]
