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" C: g' j& C9 @8 r , }% O6 {2 C' `公仔箱論壇公仔箱論壇2 T. Q* E& Q, v( Y+ ]0 V* w# Z The Incredible Magdeburg Water Bridge in Germany " q4 y6 } G+ 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.www1.tvboxnow.com4 H$ f% Q7 }) W! |1 R
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. # }: y0 p8 X" p# A# m/ q5 Q$ Dtvb now,tvbnow,bttvb4 `, {; j k6 z. O9 d. e
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。% W, X7 ~( v6 Q, N
