These pedestrian bridges across the world are pieces of art. First up, Cau Vang- A golden bridge held up by two huge stone-coloured hands in the Ba Na hills in central Vietnam. Next up is the Henderson waves in Singapore, It's a snake like structure that even glows at dawn. Lastly, the Fan Bridge in Paddington Basin in London is shaped like a Japanese Fan. It's accessible only on some days when you can see it sprawling in action.
