# x4 b: j6 M  HThe Incredible Magdeburg Water Bridge in Germany
: g; z$ j1 d" A' {0 Ltvb now,tvbnow,bttvbThe 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.
  s( k' j& x( _( v. d' a( \/ wThe 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. 4 y  i+ W! M4 C& X4 w

The aqueduct was finally completed and opened to the public in 2003. . `! `6 `9 h9 g' Z
