Even after you see it, it is still hard to believe! Water Bridge in Germany. What a feat! 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 . The photo was taken on the day of inauguration .. . .  To those who appreciate engineering projects, here's a puzzle for you 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. > > > > More . . . . 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. Have you ever seen a river over a river? AMAZING.....     --
