In Singapore it was opened in 2010 the Helix Pedestrian Bridge, a bridge that has become an architecture masterpiece by its double helix structures made from stainless steel. The design was inspired by the geometric helicoidal arrangement of DNA, which is seen as a symbol of continuity and renewal. This bridge is 280 meters long and it is the first double-helix bridge in the world, it has a very lightweight structure built almost entirely using duplex stainless steel.
