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. K: x5 f4 V7 L _ ! ~, s8 L; f4 B

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.tvb now,tvbnow,bttvb* O' c+ P8 E$ D0 D, l, C
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. 2 l, Z& o q5 ctvb now,tvbnow,bttvb5.39.217.77:88981 L1 x p" c0 }* X S% T
Construction of the water link was started as early as in the 1930s but due to the World War 2 and subsequent division of Germany the work remained suspended till 1997. The aqueduct was finally completed and opened to the public in 2003. 9 _/ i1 |2 Y9 W4 P4 q" W- l- w!
