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 3 W! Z3 a0 W5 R / }3 _+ D' t1 p, R3 i 2 O+ K" i* ]6 [The Incredible Magdeburg Water Bridge in Germany) @ x' A2 D% F; f* r- @2 C1 Y1 f
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.5.39.217.77:8898! Z5 o. Y& K Q3 i7 t, ]# m! x
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. 5.39.217.77:8898: \- l# [. x8 X! U

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。# ^2 D, ~8 ?: L4 H4 e1 L w: E3 a
