Rolling Bridge is a bridge that can roll itself without human assistance. Rolling Bridge designed by Heatherwick Studio. The award-winning Rolling Bridge is located in Paddington Basin, London. Instead of using conventional open the bridge mechanism, consisting of a single rigid element that rises to let boats pass, the Rolling Bridge to roll themselves up to the two ends meet. When in a horizontal position, the bridge is a bridge of iron and wood pedestrian normal; fully open, the bridge is in a circle on one side that is different from the straight position. Twelve feet in length, the bridge is made by eight pieces of iron and wood, and made curved by hydraulic power mounted on the handrail of each section.
