Mackay Ring Road

We are delivering an improved link from the south to the northern suburbs to reduce traffic through Mackay.

We are constructing a new 11.3km ring road route which will connect the Bruce Highway at the Stockroute Road roundabout in the south through to Bald Hill Road in the north. 


  • Improves safety
  • Better road access
  • Increases capacity
  • Improves network efficiency

Key features

  • Upgrading a 1.6km section of the Peak Downs Highway, between Horse and Jockey Road and Sextons Road, to a dual carriageway.
  • New network connections at the Bruce Highway south, Peak Downs Highway and Bruce Highway north.
  • A new crossing of the Pioneer River.

Infrastructure naming

Thank you to all those that submitted. We received over 70 nominations!

Each submission will now be assessed against a mandatory criteria to ensure it meets the naming principles, before progressing to an external naming committee for assessment.

The naming committee will make recommendations to the minister for Transport and Main Roads.

The focus of the naming is the Mackay Ring Road’s largest structure – the Pioneer River Bridge. Other bridges may be named depending on the number and quality of submissions. The successful names will be announced later this year.

Pioneer River crossing

The Mackay Ring Road crosses several waterways. To reduce flood impacts on the region four new bridges and nine overpasses will be built. The 670m Pioneer River crossing will be the largest bridge structure built on the Mackay Ring Road. This crossing will create a vital connection between the north and south of Mackay.

Peak Downs Highway upgrade

A 1.16km duplication of the Peak Downs Highway, between Horse and Jockey Road and Sextons Road, is included as part of the Mackay Ring Road project.

The upgrade allows for the integration of the new Peak Downs Highway overpass, with a clearance height of 5.5m, and an on-ramp and off-ramp.

A feature of the upgrade is the construction of a shared bicycle/pedestrian pathway.

Network Connections

The Mackay Ring Road project includes the construction of new connections at the Bruce Highway south, the Peak Downs Highway and the Bruce Highway north.

New dual-lane roundabouts will be constructed at the southern end at the Stockroute Road and Calrossie Road intersection and at the northern end just north of Bald Hill Road. A new interchange will be constructed at the Peak Downs Highway.

Local content

We partnered with the Department of State Development, Manufacturing, Infrastructure and Planning to consult with local businesses and communities to maximise the opportunity for local content on the project.

The Mackay Ring Road Supply Chain Development Program provided interested companies with the tools and information required to increase their chances of securing work, not only on the Mackay Ring Road project but also to develop their business to meet the needs of Tier 1 construction companies in the future.

Central Queensland workers from varied industries, including manufacturing, transportation, crane, supply and production, have displayed their capabilities on the project.

An example is the manufacture, transportation and placement of 108 T-girders on the new Pioneer River crossing. Each T-girder, weighing up to 82 tonnes, measuring 1.8m  tall and 35m long was created in a specialist precast concrete facility in Rockhampton. Regional and local workers then transported each of the 108 T-girders the 333 kilometres between Rockhampton and Mackay, using pilot escorts.

Local content has been a major achievement on the project. In early 2020, more than $152 million worth of packages had been let to local and regional suppliers and nearly 1700 people had been inducted on site

Video Transcript

Daniel Pinkney: Project Manager, Mackay Ring Road: 

The Mackay Ring Road project joins the Bruce Highway from the south of Mackay up to the Bruce Highway to the north of Mackay.  

Sam West: Project Manager, CPB Contractors:  

It’s 11.3 kilometres of highway. The purpose of it, is to get traffic off the existing Bruce Highway at Nebo Road, provide better connectivity to the port and the industrial areas of Mackay and also connection to the west on the Peak Downs Highway, to the Bowen Basin  

Caption: The project is being delivered as part of the Bruce Highway Upgrade Program. Funding for Stage 1 of the Mackay Ring Road is $497.3 million 

Daniel Pinkney: 

It cuts out around 10 sets of traffic signals in the Mackay area. It also means that all the freight transport moving north and south along the Bruce Highway doesn’t have to enter into the Mackay CBD area. 

Sam West: 

13 structures across the project, they go over a variety of cane rail, local roads, Peak Downs Highway, the Pioneer River. 

Kirsty Hogarth: Senior Community Relations Advisor, CPB Contractors: 

Over 70 per cent of our suppliers and sub-contractors actually come from either Mackay itself or from the region. 

Sam West:  

The majority of our suppliers are local here, whether it’s quarry material, embankment fill, concrete supply, all that sort of stuff is building the economy here in Mackay. 

Kirsty Hogarth: 

You know, the community is embracing it, they are learning about it, we find people are interested in the job. They don’t actually understand the scale of the job. They’re like "Wow, we didn’t realise it was that big." 

Sam West:  

When people move to Mackay to build an infrastructure project like this, those economic benefits flow through to the community. Whether it’s people renting houses, people shopping at the local supermarket, all that sort of thing is something this project delivers. 

Caption: Works are due to be completed on the project by mid-2020
