It only needs to be designed to withstand the weight of the water! 5.39.217.77:88988 E( N. Q$ i0 y
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

The Incredible Magdeburg Water Bridge in Germany公仔箱論壇9 \" [ ]6 H1 }4 b9 M
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.
# ?, J% ~( P# D3 Y/ F& N$ }5 LThe 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. 5.39.217.77:8898* z4 e+ k0 n- P% |5 h9 c" O& j$ t9 B

The aqueduct was finally completed and opened to the public in 2003.
