Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded公仔箱論壇2 p/ x' e- p9 u, ~ 7 v, I6 V( v3 P$ K2 k

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. $ Q6 h9 `! T: {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。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. 8 S- ^: l5 ?1 |- {6 [

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. 1 K! z" v+ q& ~' k7 J) }tvb now,tvbnow,bttvb0 y4 F7 D& @* c1 E: i- `
