Water Bridge in Germany, where one river crosses over another river via a man-made bridge.
Even after you see it, it is still hard to believe! A What a feat! Why isn't this being touted as one of the Wonders of the World?
It is 918 meters long, took six years to build and cost 500 Euros. A wonderful feat of 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.

To those who appreciate engineering projects, here's a puzzle for you armchair engineers and physicists.
Q) 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.
