The Helix Bridge , previously known as the Double Helix Bridge , is a pedestrian bridge linking Marina Centre with Marina South in the Marina Bay area in Singapore. It was officially opened on 24 April 2010 at 9 pm, however only half was opened due to ongoing construction at the Marina Bay Sands. 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.

The bridge complements other major development projects planned in the area, including the highly-anticipated Integrated Resort Marina Bay Sands, Singapore Flyer, Gardens by the Bay and the 438,000 m² business and financial centre which will be ready by 2012.

Design and architecture

The design consortium is an international team comprising Australian architects the Cox Group and engineers Arup, and Singapore based Architects 61. The bridge is expected to be a focal point for the community, linking cultural, recreational and entertainment facilities in the area and complements the overall pedestrian scheme of Marina Bay. The bridge also functions as a gallery where children's paintings and drawings are exhibited for public viewing.

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 five 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 will be 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 Helix is fabricated from approximately 650 tonnes of Duplex Stainless Steel and 1000 tonnes of carbon steel used in the temporary structure and also helping the bridge to get the helix shape.

The Land Transport Authority claims it is a world first in architectural and engineering bridge design.

The construction of the bridge was undertaken by the collaboration of Sato Kogyo Pte Ltd and TTJ Design and Engineering Pte Ltd. Both companies had their full support to help to create this bridge. Sato Kogyo specialized in building a concrete span bridge which is located parallel to the Helix bridge while TTJ Design and Engineering led in the fabrication and erection of the Helix structure. Key personnel in the project from TTJ Design and Engineering were Mr Teo Hock Chwee (Managing Director), Mr Srirama Raju (DGM), Mr Gaynel Velasco (Senior Project Manager), Mr Teo Teck Heong (GM), Mr Arnel Alcorin (APM), Mr Tiung Chee Wee (Engr) and many others who contributed to the whole span of the bridge. Hundred of workers have contributed to the completion of the bridge.
