It only needs to be designed to withstand the weight of the water! 5.39.217.764 h5 H' J& s5 |, R' @! u+ o
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: i! g" y' |/ P

The Incredible Magdeburg Water Bridge in GermanyTVBNOW 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。7 B# V; O/ j; p" I9 `% d
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.
# B. d# H" O- e4 sThe 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.
