The double-helix design was inspired by the structure of deoxyribonucleic acid (DNA) to symbolize life and continuity.
The structure comprises two delicate, spiraling steel members that are held together by a series of connecting struts.
The bridge incorporates pairs of colored letters 'c', 'g', 'a', and 't' into its design, representing the four bases of DNA: cytosine, guanine, adenine, and thymine.
The lights on the bridge are configured to glow in different colors, with 'c' and 'g' illuminated in red and 'a' and 't' in green at night.
The total weight of the stainless steel used for the bridge is approximately 650 tonnes.
The design team consisted of an international consortium including Architects 61, Cox Group, and Arup.
It is the first curved bridge in the world to feature a double-helix structure.
The bridge uses 40,000 meters of stainless steel tubing.
The Helix Bridge is a 280-meter pedestrian link bridge in Singapore, specifically engineered with a double-helix structure mimicking the geometry of human DNA. It connects the Marina Centre with the Bayfront area, serving as a critical artery for the Marina Bay district. The structural design consists of two spiraling stainless-steel members held together by a series of struts. At night, the structure is illuminated by programmable LED lights that highlight the double-helix form. The bridge features five circular observation platforms that offer panoramic views of the Singapore skyline and Marina Bay. It is a vital component of the 3.5-kilometer walkway loop that encircles the bay area. The bridge is constructed primarily from stainless steel to minimize maintenance requirements in the humid tropical climate.
From the ground level on the promenade near the ArtScience Museum, looking up at the bridge's curve.
Walk the full length to visit the five dedicated viewing pods for unobstructed photography.
Visit after dusk to see the LED lighting system in action, which significantly changes the bridge's visual impact.
Combine your walk with the nearby Marina Bay Sands promenade for a complete circuit of the waterfront.
Do not attempt to cycle on the bridge as it is designated for pedestrians only.
