River Over A River If You Are Not A Physics Person, Read The Last Paragraph And Learn A Fact Of Physics.  Have You Ever Seen A River Over A River ????????  AMAZING.....      Even After You See it, it is Still Hard To Believe! Water   Bridge in Germany . What A Feat !  The Photo Was Taken On The Day Of inauguration . . .    To those who appreciate engineering projects, here's a puzzle for your  armchair engineers and physicists.   Question:    Did that bridge have to be designed to withstand the additional weight of ship and barge traffic, or just the weight of the water?    Answer:     It only needs to be designed to withstand the weight of the water!    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.  Six years, 500 million Euros, 918 meters long . . . now, this is engineering!    This is a channel-bridge over the River Elbe and joins the former East and West Germany , as part of the unification project. It is located in the city of  Magdeburg , near Berlin .       Saturday, April 23, 2011 The Incredible Magdeburg Water   Bridge in Germany 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.  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.       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. was finally completed  and opened to the public in 2003.
