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* |) n9 o4 v7 J- G

The Incredible Magdeburg Water Bridge in Germany
. Q- Z2 {8 M! q7 ]# d& Xtvb now,tvbnow,bttvbThe 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.
- e( T$ J5 T% F9 Y. J+ D' R3 m& r3 nThe 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. & x4 J3 k1 h" Z

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. tvb now,tvbnow,bttvb5 U2 a1 K7 m" m% Y$ I3 Y7 r
