It only needs to be designed to withstand the weight of the water! : S% A d1 ~! U S4 {/ Z. Z
Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded6 _; A' r0 f6 E8 U! ?: t. b6 k 5.39.217.77:8898: s; l. L4 k2 Z7 N

At 918 meters, it is the longest navigable aqueduct in the world.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。& a) b0 D* b- b2 N3 F" D
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. . p% e' K' |) }

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. V! v1 A* J' Q1 K* H2 Q
