Helix Bridge – Singapore

The Helix Bridge provides a pedestrian connection across the head of the Singapore River between the city’s existing CBD and its new Bayfront district.  Its commission was the result of a selected 36-entry international design competition held in 2006.

The plan concept was to curve the bridge in an arc so that it arrives fluidly into foreshore promenades on each side.  It also enabled the bridge to connect in its centre to an adjacent vehicular bridge’s footpath while shifting away from it beyond this point of junction.

Seeking a delicate, lightweight contrast to the vehicular bridge, the concept evolved of a double helix structure.  This form enabled the canopy, required by the brief, to be integrated as segmented panels of glass and perforated steel, unlike other bridge structures. The structural typology also proved highly effective in working to a curvilinear plan, and in generating an intriguing sense of movement flow along the journey.

The Helix Bridge is illuminated at night by ribbons of LED lighting accentuating the interplay of the two helix tubes and their intervening, connecting ties.  Four ovular-shaped ‘pods’ cantilever out from the structure enabling people to gain wider appreciation of the bridge form and providing gathering space for viewing bay events.
