The Helix is fabricated from approximately 650 tonnes of Duplex
Stainless Steel and 1000 tonnes of carbon steel used in the temporary structure and also helping the bridge to get the helix shape. The construction began in 2007. It was officially opened on 24 April 2010 but partially accessible. The

A mobile gantry crane was positioned on the temporary bridge to lift elements into place. Erection started from the North

The duplex stainless steel used is susceptible to contamination by carbon or zinc dust. So a dedicated workshop was specially set up to keep members for the Helix separate from other carbon and nitrogen steels.
