This weekend the world’s first double helix bridge will open, closing the loop on a 3.5 kilometer pedestrian path around the Marina Bay development in Singapore. Inspired by the helicoidal structure of DNA, the pedestrian bridge stretches 280 meters over the bay and includes a computer-controlled lighting system to set the mood. The bridge’s grand opening will coincide with the unveiling of Singapore’s first art park, the nearby Youth Olympic Park.

Designed by Australian firm Cox Group, engineering firm Arup and Singapore-based Architects 61, the bridge is made up of a major and minor steel helix that wind around each other. If the steel was stretched out straight end to end, it would “measure 2,250 meters long, and the entire structure weighs about 1,700 tons, which is equivalent to about 1,130 saloon cars.” Special lighting (hopefully LED!) built into the bridge can be programmed to create special moods.

The bridge, which is yet to be officially named, will open this Saturday, April 24th, with a big celebration including fireworks and special performances from artists, music groups and even a cheerleading squad. The new pedestrian bridge links Marina Centre and Marina South, which are both areas of the Marina Bay project, a large development including high end resorts and a business and financial center.
