It only needs to be designed to withstand the weight of the water! 4 a9 }4 N, u8 L( Q3 J0 N) 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. I5 N% s, w! G; \" V; c& {

The Incredible Magdeburg Water Bridge in Germany5.39.217.768 ?5 l0 u4 g f
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.3 M" t! J/ x/ W# f4 f4 V8 p: ?. l
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. tvb now,tvbnow,bttvb3 r5 O+ o% X( ?/ H7 R
