Bruce Highway Upgrade – Caloundra Road to Sunshine Motorway, Caloundra, Sunshine Coast, Queensland, Australia

One of Queensland's highest priority road projects

In a joint venture with Jacobs, Arup has been appointed as designer for the Fulton Hogan Seymour Whyte Joint Venture (FHSW JV) to construct the Bruce Highway Upgrade – Caloundra Road to Sunshine Motorway on Queensland’s Sunshine Coast.

The project involves an upgrade of the Bruce Highway to six lanes, including major upgrades to both interchanges and the delivery of a service road for local traffic on the western side of the highway between Steve Irwin Way and Tanawha Tourist Drive.

The FHSW JV developed an innovative design solution that transforms the Caloundra Road interchange into a Diverging Diamond Interchange (DDI), the first to be built in Australia. The DDI is a unique design for reducing traffic congestion and improving safety for motorists, pedestrians and cyclists. It also uses a smaller footprint than traditional interchange designs.

It is among Queensland's highest priority road projects and is designed to meet the strategic transport needs of the Sunshine Coast region in this area well into the future. The upgrade will deliver critical safety benefits to motorists, improve efficiency and reduce traffic congestion, and ensure the highway can cater for future traffic growth. The speed limit on the upgraded highway will be returned to 110km/hr, and immunity will be provided from a 1-in-100 year flood event.
