Breathtaking Double-Helix Bridge

The Helix Bridge is the winning proposal for Singapore's international design competition which beat out 36 other selected designs. This pedestrian bridge stretches across the head of the Singapore river and connects the city's new Bayfront district and its Central Business District. A collaborative project between architecture firms Cox Architects and Architecture 61, the design was originally one long fluid curve that contrasted a nearby vehicular bridge but then evolved into that of a double helix form; becoming the only double helix bridge in the world.

Due to the unique design, the elegant curve remains while a sleek canopy of glass and steel panels now hangs overhead. There are four pod like structures that cantilever off of it to allow pedestrian observation points. These come in especially useful during festivals and other celebrations that take place on the river. At night, the bridge is lit up by a number of LEDs that run its entire length of almost 920 ft. It uses less steel than if it were a more conventional, boxier bridge and is constructed entirely out of stainless steel. Breathtaking, isn't it?
