It only needs to be designed to withstand the weight of the water! 公仔箱論壇1 T$ L# }( D/ {* @* ^" A
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

8 g0 f5 s N1 w4 N( Ktvb now,tvbnow,bttvbThe 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.
$ S) _! P/ D) z公仔箱論壇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; C* q2 l% m0 J2 I9 x! v
( q2 ? U& n% i4 `4 s5 _5.39.217.77Construction 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.
