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.公仔箱論壇! Z: i. V3 ]! @
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. 5 Q' ~# n. [* `8 {6 t5.39.217.77:8898 0 Q.

The aqueduct was finally completed and opened to the public in 2003. ! o7 s2 L& H" r/ [公仔箱論壇 0 a0 s. {- g5 i9 I公仔箱論壇) ?6 v2 F$ `* v9 | [attach]1486500[/attach]! h( w( h8 g/ F0 ]. h [attach]1486501[/attach]- P( y9 ?( l( O, V [attach]1486502[/attach]公仔箱論壇( P# e7 X: T, e# j8 U [attach]1486503[/attach]( O/ K# q$ s( J6 w* H* G [attach]1486504[/attach] 5 v. @: _0 q* l% k9 T; c9 L# j, Btvb now,tvbnow,bttvb[attach]1486505[/attach]公仔箱論壇( L1 R, @1 l; I! ]# p( O. l
