Helical design for footbridge

The M8 Harthill footbridge is a new, bold and elegant structure. A 40 year old existing bridge previously connected the motorway services to the town of Harthill but his fell into a state of disrepair and no longer met modern access requirements. The replacement bridge concept was developed in 2006 to create a safe durable access across the motorway and to provide an iconic symbol for all who use and travel beneath it. The main span of the footbridge is a 90m long double helix steel truss. The bridge is subtly curved in elevation and, unlike its predecessor at Greenside Place, it is perfectly straight in plan. This article explains the challenges of its design.
