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.* y6 |) g/ q* E9 r! [
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. ; D6 ]8 g6 i" a! h9 _7 h+ O- ^公仔箱論壇2 c& _8 Z0 `4 P/ ], x& E3 K# j1 P- _
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. # V A5 M; h0 Z ; M# P, {8 L3 N6 v" I1 U' S5.39.217.77:8898tvb now,tvbnow,bttvb- \! g7 C3 I.
