The human brain has discovered the dynamics of this universe and applied them in every walk of life. One of such a marvellous application includes the unique and magnificent Helix Bridge of Singapore. Inspired from the design of DNA helical structure, Helix Bridge stands in the vicinity of Marina Bay over Singapore River linking Marina centre with Marina South. The Helix Bridge was also called Double Helix Bridge. The construction of this innovated and technologically advanced Helix Bridge started in 2007 and ended in 2010, when it was finally opened to the general public (24 April 2010/ 9 pm). This footbridge is 280 m in length which covers the entire walkway around the Marina Bay.
The inbuilt structure of Helix Bridge is composed of canopies made of fretted-glass and perforated steel mesh. The canopies are linked with the parts connected to the inner spiral of the Helix Bridge. The main function of the canopies is to provide shade to the pedestrians. The fabrication of Helix Bridge includes approximately 650 tonnes of Duplex Stainless Steel and 1000 tonnes of Carbon Steel. The Stainless Steel and Carbon Steel is used in temporary structure and is a help in maintaining the helix shape of the bridge. The bridge design uses the idea of four bases present in DNA. DNA is composed of four bases adenine, guanine, cytosine and thymine. These base pairs are represented by c, g, a and t by red and green lights in the left handed double helix design bridge. The views of Singapore skyline and Marina bay events can be witnessed from the outstanding four viewing platforms of the Helix Bridge. The Helix Bridge design utilizes series of lights to highlight the double helix structure of DNA and hence visitors are fascinated by the special visual experience.
The credit for such a flawless design goes to the Australian architects Cox Group and engineers Arup in collaboration with Singaporean architects. The Helix Bridge as Claimed by the Land transport Authority is one of its kind in architectural and engineering bridge design. ‘World’s Best Transport Building’ award was given to this marvel at the World Architecture Festival Awards. The architecture of this bridge is also recognized by Building and Construction Authority (BCA) at the BCA Design and Engineering Safety Excellence Awards in 2011.
