Bruce Highway Upgrade – Caloundra Road to Sunshine Motorway


The project involves upgrading the Bruce Highway to 6-lanes between Caloundra Road and the Sunshine Motorway. This includes major upgrades to both interchanges and the delivery of a 2-way service road for local traffic on the western side of the highway between Steve Irwin Way and Tanawha Tourist Drive.

Construction is expected to be completed in late 2020, weather permitting.


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.


The $812.95 million project is funded on an 80:20 basis under the Infrastructure Investment Program with the Australian Government contributing $650.36 million and the Queensland Government contributing $162.59 million.

This project is part of the 15-year Bruce Highway Upgrade Program, a $12.6 billion program of works to improve safety, flood resilience and capacity along the Bruce Highway from Brisbane to Cairns. The program is jointly funded by the Australian and Queensland governments, with the Australian Government contributing up to $10 billion and the Queensland Government contributing up to $2.6 billion.

Project timeline

The Bruce Highway Upgrade – Caloundra Road to Sunshine Motorway will provide vital infrastructure to the community and is designed to meet the strategic transport needs of the Sunshine Coast region well into the future.

The upgrade is vital for the continued development of the Sunshine Coast and with the increased capacity, the highway will provide safer and more efficient travel for commuters and industry along this stretch. The upgrade will separate long distance traffic from local traffic, allowing the highway to function as a high-speed, high-volume corridor. It will also cater for a 1% annual exceedance probability (AEP) flood event—that is, a flood event which occurs on average once in 100 years. 

Key features of the design layout

Design layout (May 2017)

  • Provision of a revised southbound exit from the Bruce Highway to Pignata Road. The new exit ramp will provide safe and direct access to local businesses and residences, as well as a future connection to the Harmony development in Palmview.
  • Reduction of the project footprint on the Beerwah State Forest.
  • Transformation of the existing Caloundra Road interchange into a Diverging Diamond Interchange.
  • Removal of the intersection on the Bruce Highway northbound exit ramp to the Sunshine Motorway near Wilson Road. The intersection will be replaced with new free-flowing, grade separated ramps to significantly improve safety for northbound motorists exiting and entering the Bruce Highway.
  • Inclusion of a secondary access to the western service road at the Sunshine Motorway interchange for northbound traffic on the Bruce Highway.
  • Provision of a direct access to the Sippy Downs interchange from the western service road for local traffic.
  • Retain all existing access ramps between the Sippy Downs interchange and the Sunshine Motorway.
  • Provision of new active transport infrastructure for bike riders and pedestrians, as well as new car pool and bus stop facilities.

Caloundra Road interchange

In an Australian first, the Bruce Highway Upgrade—Caloundra Road to Sunshine Motorway will transform the Caloundra Road interchange into a Diverging Diamond Interchange (DDI). This innovative design is cost effective because it minimises the project footprint (requires less bridges and roads) while tackling congestion, increasing capacity, improving safety and providing active transport connections.

About DDIs

Almost 100 DDIs have been used have been constructed around the world—the majority of these are in the United States. The DDI is an emerging interchange form that responds to the increasing demand to find different ways of managing increased traffic volumes within budget and land constraints. It provides an interchange type that provides improved traffic performance when compared to traditional interchanges while also delivering resilience and future flexibility. While the DDI at Caloundra Road will be the first to be operational in Australia, there are other DDIs being planned or designed for future projects across the country. 

How does a DDI work?

DDIs improve efficiency and safety by reducing the number of ways vehicles cross one another compared to traditional interchanges. Traditional interchanges have right-turning lanes in the middle of the road and drivers must wait for oncoming traffic to pass before turning right. A DDI moves right-turning motorists to the edge of the interchange allowing them to turn right without giving way to, or blocking traffic, coming the other way. Synchronised traffic signals, line marking and signage guides motorists seamlessly through the interchange and towards their destination.

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 well underway.

Bike riding and pedestrian facilities

More than 9km of new dedicated lanes and pathways for bike riders and pedestrians is currently under construction throughout the project area. These are shown by the yellow lines in the design layout.

Once completed, these lanes and pathways will extend from Caloundra Road at Meridan Plains, through the new Diverging Diamond Interchange to link with Steve Irwin Way at Glenview. 

This active transport route will be connected to 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.

The new pathway will safely connect bike riders and pedestrians with local areas via the following roads:

  • Downunder Drive (Aussie World Precinct)
  • Pignata Road (car pool facility)
  • Martin Road
  • Sippy Creek Road
  • Cunning Road
  • Tanawha Road 
  • Tanawha Tourist Drive

In addition, a dedicated new pedestrian and bike riding bridge will be constructed next to the existing Sippy Downs interchange to provide a safe link between Tanawha Tourist Drive and the educational, business and residential precincts adjacent to Sippy Downs.

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.

Bus stops

Nine new bus stops will be established in the project area to improve local access to public transport. Bus stop locations are marked in purple in the design layout

The bus stops will link to established bus routes servicing key community hubs and the broader Sunshine Coast region. 

Locations of the new stops include:

  • Steve Irwin Way, Glenview
  • Pignata Road near the new car pool facility at Palmview
  • Western service road near: 
    • Glenview Road
    • Palmview Forest Drive
    • the Aussie World precinct
    • Sippy Creek Road
    • Cunning Road.

Latest news

Major construction

Major construction is now underway and motorists should expect a number of 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 late 2020, weather permitting.

To maintain traffic flow through the interchange while the upgrade is completed, both permanent and temporary traffic changes will occur throughout the construction period.
