The Helix Bridge, officially The Helix, is a pedestrian bridge linking Marina Centre with Marina South in the Marina Bay area in Singapore. It is located beside the Benjamin Sheares Bridge and is accompanied by a vehicular bridge, known as the Bayfront Bridge. The entire bridge was opened on 18 July 2010 to complete the entire walkway around Marina Bay. Canopies (made of fritted-glass and perforated steel mesh) are incorporated along parts of the inner spiral to provide shade for pedestrians. The bridge has four viewing platforms sited at strategic locations which provide stunning views of the Singapore skyline and events taking place within Marina Bay. At night, the bridge is illuminated by a series of lights that highlight the double-helix structure, thereby creating a special visual experience for the visitors. Pairs of coloured letters c and g, as well as a and t on the bridge which are lit up at night in red and green represent cytosine, guanine, adenine and thymine, the four bases of DNA. The intentional left handed DNA-like design, which is the opposite of normal DNA on earth, earned it a place in The Left Handed DNA Hall of Fame in 2010. The Land Transport Authority claimed it is a world first in architectural and engineering bridge design. It won the 'World's Best Transport Building' award at the World Architecture Festival Awards in the same year. It has also been recognised by the Building and Construction Authority (BCA) at the BCA Design and Engineering Safety Excellence Awards in 2011.
