A 28 kilometer-long bridge is being planned to link the Middle East and Africa. The US$20 billion bridge will become the longest suspension bridge in the world and tower some 400 meters above the water, with at least three spans of around 2700m each. Undoubtedly set to become one of the wonders of the modern world, the project includes plans to build entire cities at each end, linked by a six-lane motorway and a four-track railway. Adding complexity to the enormous task, the bridge it is to be built in an area of intense seismic activity.
What a wonder this will be! Having seen other fascinating man made feats such as the Pyramids in Egypt, Machu Picchu, Christ the Redeemer, and the Collosseum, I would love to see this in the future. They say that the concrete pylons to make the bridge will have to be supported up to depths of 300m and at the same time tower 400m over the water's surface to support the ultra-long span suspension bridge. Each pylon will be 700m. It will be enormous! The pylons will have to be exceptionally strongs. Maybe a radical material such as graphene could benefit this project?
