The Incredible Magdeburg Water Bridge in Germany; o. L' k) i* S0 s/ s5 u' Z! a% l1 _
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.
2 L" k* x6 Q6 B3 N5 X1 yTVBNOW 含有熱門話題，最新最快電視，軟體，遊戲，電影，動漫及日常生活及興趣交流等資訊。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.
" i  p  z* J; u8 P; `5 Q, L; ]: I' P5 V  @3 i! r
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.
