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 & B) d% r q6 {) T/ XTVBNOW 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 `: f" Z% Z8 E2 e. a' e! l" `! q% N( ?& X$ M. l% I9 l5 b( l1 ~ The Incredible Magdeburg Water Bridge in Germany ! U' N: X/ U9 n* o3 p/ ^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.! t0 X& D+ k, v# ?, `$ p. H. m
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. ) W7 c' T9 r- v; Ctvb now,tvbnow,bttvb # v/ x- i( {7 hTVBNOW 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。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. tvb now,tvbnow,bttvb2 X" v6 ]- J" f0 s2 K1 Y
