The Helix Bridge provides a pedestrian connection across the head of the Singapore River between the city's existing CBD and it's 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. Its curved arc in plan enables people to descend continuously into the Bayfront promenades on each side, linking these points with existing major cultural facilities such as the Michael Wilford- designed Esplanade National Performing Arts Centre.

Britflex BEJ expansion joint system was specified by the client (Urban Redevelopment Authority) for a number of reasons:
Britflex BEJ is a surface mounted mechanical system, with an elastomeric insert between two metal runners/carrier rails. Set into a rapid curing resin compound known as Britflex® Resin Mortar. The polyureide resin provides unrivalled anchorage to the deck due to its remarkable bonding qualities, meaning that no mechanical fixings are required.
The project was completed on time and budget to the complete satisfaction of the main contractor and client.
