The Helix Bridge, officially The Helix, and previously known as the Double Helix Bridge, is a pedestrian bridge in the Marina Bay area in Singapore. The entire bridge was opened on 18 July 2010 to complete the entire walkway around Marina Bay.

From the outset, the project posed several challenges. There was a desire for the plan view of the bridge to be curved in an arc, such that it joins the foreshore promenades on either side seamlessly. Furthermore, it was desirable to create a lightweight structure, in contrast to the adjacent 6-lane vehicle bridge which is rather heavy in appearance.

Because this structure was inspired by the DNA structure, it appeared essential that the architectural lighting features should emphasise the various shapes and curves.
