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 + V! Z# m0 D: f5.39.217.77:8898tvb now,tvbnow,bttvb5 \7 b. v W* [7 M' E2 K; S* X

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.tvb now,tvbnow,bttvb! Y9 `3 D5 R; g% N
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. - j( P2 C; J7 X0 b公仔箱論壇5.39.217.77:8898( K" G# j! g8 n* Z/ y; V
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. 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。$ V3 J$ \ J' ? W1 ?
