Bruce Highway Upgrade—Caloundra Road to Sunshine Motorway

The Bruce Highway is being upgraded to 6-lanes between Caloundra Road and the Sunshine Motorway including major upgrades to both interchanges and a new 2-way service road for local traffic between Steve Irwin Way and Tanawha Tourist Drive.

The upgrade is being delivered to provide vital infrastructure that will support the growth of the Sunshine Coast region well into the future.

Through the upgrade we will separate long distance traffic from local traffic, allowing the highway to function as a high-speed, high-volume corridor. We will also ensure improved flood immunity of the corridor.


  • Improves safety
  • Increases traffic flow
  • Increases capacity
  • Contributes to regional growth
  • Improves network efficiency
  • Reduces peak hour congestion
  • Improves flood immunity
  • Better road access

Key features

  • A new southbound exit ramp from the Bruce Highway to Pignata Road to provide safe and direct access to the local road network, as well as a future connection to the Harmony development in Palmview.
  • A Diverging Diamond Interchange to replace the existing Caloundra Road interchange.
  • Reduction of the project footprint on the former Beerwah State Forest.
  • New free-flowing, grade separated ramps replacing the existing intersection on the old Bruce Highway northbound exit ramp to the Sunshine Motorway near Wilson Road.
  • A secondary access to the western service road at the Sunshine Motorway interchange for northbound traffic on the Bruce Highway.
  • Direct access to the Sippy Downs interchange from the western service road for local traffic.
  • New active transport infrastructure for bike riders and pedestrians, as well as new car pool and bus stop facilities.

Bruce Highway Upgrade—Caloundra Road to Sunshine Motorway: project flyover

Caloundra Road interchange

In an Australian first, the Caloundra Road interchange has been transformed into a Diverging Diamond Interchange (DDI) through this project. The new interchange became fully operational in December 2020, with all lanes and ramps open to traffic. The DDI's innovative design is cost effective because it minimises the project footprint (requires fewer bridges and roads) while tackling congestion, increasing capacity, improving safety and providing active transport connections.

Sustainable and active transport infrastructure

A key consideration of the project is improving connectivity to provide safe and sustainable travel between Caloundra Road, Steve Irwin Way and Tanawha Tourist Drive. The new car pool facility at Palmview has opened to the public and is used daily by commuters. Construction of new active transport infrastructure for bike riders and pedestrians and new bus stops is nearing completion.

Bike riding and pedestrian facilities

A new dedicated pedestrian and bike riding bridge next to the existing Sippy Downs interchange is now open. The bridge improves safety and access to the educational, business and residential precincts at Sippy Downs.

Construction of more than 9km of new dedicated lanes and pathways for bike riders and pedestrians is also nearing completion throughout the project area. These are shown by the yellow lines in the design layout (PDF, 3.63 MB)

Once completed, these lanes and pathways for bike riders and pedestrians will:

  • extend access from Caloundra Road at Meridan Plains, through the new Diverging Diamond Interchange to link with Steve Irwin Way at Glenview
  • provide a major new pathway running the entire length of the new western service road from Glenview in the south to Sippy Downs in the north
  • improve access to the local road network.

Pignata Road car pool facility

The new car pool facility between the Bruce Highway and Pignata Road at Palmview opened to the public in late 2017. 

Catering for 240 vehicles in a safe, well-lit location, commuters are able to park their vehicles and travel with their colleagues, family and friends to destinations both north and south of the coast.

The facility will ultimately connect to bus facilities, local businesses and the Aussie World precinct via a new pedestrian path. 

Environmental management

We are consulting with the community, key stakeholders and all levels of government on environmental issues relating to the project. Through this consultation, we have been successful in managing the project’s environmental impacts throughout the design and construction stages of the project.  

As part of this consultation, we have engaged with numerous environmental and community groups to share information and gain feedback.

Key local representatives include:
  • Save the Steve Irwin Way Forest Group
  • Sunshine Coast Environment Council
  • Mooloolah River Water Watch and Landcare Group
  • Wildlife Preservation Society, Sunshine Coast Branch
  • Queensland Koala Crusaders
  • Sunshine Coast Koala Rescue
  • Kabi Kabi First Nation.

For more information about the environmental stakeholder meetings (and their minutes) and our environmental management on the project contact us via email or phone.

Compliance reports

Major construction

We are currently undertaking major construction. To maintain traffic flow, both permanent and temporary traffic changes will occur throughout the construction period and motorists should expect changed traffic conditions on the Bruce Highway, Sunshine Motorway, Caloundra Road and Steve Irwin Way. This includes temporary lane closures, speed reductions, detours and minor road realignments.

Works will be completed during the day whenever possible. Due to the nature of the works and the proximity to live traffic, some activities will need to be completed at night when traffic volumes are lower. This will ensure the safety of motorists and workers. 

Construction working hours are:

Night works: Sunday to Thursday, 7pm to 5am

Day works: Monday to Saturday, 6am to 6pm.

Construction is expected to be completed in mid-2021, weather and construction conditions permitting.
