The Helix Bridge
A pedestrian bridge shaped like DNA — but deliberately left-handed, the mirror image of every molecule in your body.

The 650-tonne steel structure replicates a double helix with an intentional twist: it spirals left, opposite to natural DNA on Earth. That quirk earned it a place in the Left Handed DNA Hall of Fame in 2010, and it won World's Best Transport Building at the World Architecture Festival the same year. After dark, the geometry lights up and the helix reads as a structure, not just a bridge.
What to look for
- Letters c, g, a, t glowing red and green on the bridge at night — each pair marks one of the four DNA bases: cytosine, guanine, adenine, thymine
- Fritted-glass and perforated steel mesh canopies overhead along parts of the inner spiral, built to shade pedestrians mid-crossing
- Four viewing platforms spaced along the bridge, positioned for sightlines across the Singapore skyline
Walk it after dark for the full light display; the bridge is a live pedestrian crossing linking Marina Centre to Marina South.
The Helix Bridge is one of 30 sights worth the detour in Singapore, all bundled offline in Voyage GO — download the Singapore pack and it sits on your map with no signal, filling your travel passport the moment you walk past.
