Project description

The Peak Downs Highway is a strategic road linking mining and agricultural activities in the Bowen Basin and the Central Highlands districts to Emerald and Mackay, and to the ports of Mackay, Abbot Point and Hay Point.

This project will strengthen and widen approximately 13km of the Highway, providing a wider and safer two-lane highway, which will better accommodate over-size and over-mass freight vehicles.


The project builds on existing Australian and Queensland government investments on the Peak Downs Highway and will provide the following benefits:

  • improved safety, through provision of recovery areas, pavement protection and increased separation between heavy vehicles, caravans and light vehicles
  • improved freight efficiency, through pavement strengthening and widening
  • reduced road maintenance costs, through upgrading of the overall road standard


The Australian Government has committed up to $28 million towards this $35 million project.


Construction commenced in early 2021 and is was completed Dec 2023.
