It only needs to be designed to withstand the weight of the water! tvb now,tvbnow,bttvb- n! f8 Q5 i) N5 C6 v
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 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.
, H: L/ t! g$ S# g2 K& ^, s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.
