It only needs to be designed to withstand the weight of the water! 5.39.217.77:8898( x& ^0 l7 `8 l6 E
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 , m$ s' h0 G!

At 918 meters, it is the longest navigable aqueduct in the world. ( C$ Y0 ` R7 {/ Y& r5.39.217.77:8898The 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. 3 P C4 o: Z: j( \1 T8 f

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. , L# H l9 S2 A4 m7 ^tvb now,tvbnow,bttvb公仔箱論壇8 |8 A- c. T; Z2 Y3 F
