The Helix Bridge provides a pedestrian connection across the head of the Singapore River between the cityâs existing CBD and its new Bayfront district. Its commission was the result of a selected 36-entry international design competition held in 2006.ost / Value Arup found that for its 280 metre length, the dual helix structure utilises 5 times less steel than a conventional box girder bridge. This finding enabled the client to direct the structure to be constructed entirely of stainless steel for its longevity.
