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 , I+ n4 E" ^6 q4 atvb now,tvbnow,bttvb; S1 {6 ^7 K( c+ C/ S8 \; g1 c

At 918 meters, it is the longest navigable aqueduct in the world. * Y: f: ]: H!

Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo. 7 a$ g% s0 }! ^2 l

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. 2 G/ [- G/ G( r8 Nwww3.tvboxnow.comtvb now,tvbnow,bttvb! X7 o5 j- _6 s' D& `: s
