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. ' `8 c& T4 {# A! K( f& CThe 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. / I0 x- K% x& d. ?# Y公仔箱論壇tvb now,tvbnow,bttvb9 G% b/ O8 b8 X0 Z. w" @/ 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. ) j1 ^: Z0 b+ B7 ^+ g 8 Q* }# i' a: v( R5.39.217.77:8898 * D- `5 o. ?7 P4 M$ C4 S# D5.39.217.77:8898[attach]1486500[/attach]tvb now,tvbnow,bttvb# `+ P2 \: B8 k0 Q [attach]1486501[/attach]" l7 a9 ?2 p" W* j } [attach]1486502[/attach] " b/ e; x0 s: Z7 X3 f3 Y Q5 e% d3 i[attach]1486503[/attach]# c7 A8 E/ z3 {2 k$ O7 P. r [attach]1486504[/attach]TVBNOW 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。, _8 _( c9 S. r& v) O# Q [attach]1486505[/attach]TVBNOW 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。7 q5 Y2 A, Q" ~1 k3 f0 w
