Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded5.39.217.77:88983 Q. r9 K8 ~2 @4 X8 T7 a' b6 }

R/ q8 H' h; O* ]7 h) y8 i公仔箱論壇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.
1 o5 z$ N& w6 Q. y6 Q2 ttvb now,tvbnow,bttvbThe 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.

The aqueduct was finally completed and opened to the public in 2003. 公仔箱論壇% I% F2 F6 O5 U; k2 M
