Bruce Highway Upgrade Program: St Lawrence overtaking lanes


This package of work will build 3 new overtaking lanes on the Bruce Highway between St Lawrence and Mackay near Kalarka Road, Mosquito Creek and Carmila. 

These works are a part of the Bruce Highway Upgrade Program (BHUP), a 15-year program of works jointly funded by the Australian and Queensland Governments to improve the safety, flood resilience and capacity of the Bruce Highway between Brisbane and Cairns. Although being delivered under the BHUP, these overtaking lanes are fully funded by the Australian Government.


Bruce Highway (St Lawrence – Mackay).


March 2020.


The project will deliver safety benefits to road users and reduce driver frustration by:

  • improving overtaking opportunities and travel times
  • increasing freight and heavy vehicle management along this corridor.

Kalarka Road and Mosquito Creek overtaking lanes – $7.3 million.
Carmila overtaking lane – $7.5 million.

Total package – $14.8 million, fully funded by the Australian Government. 

Central Region - Mackay Whitsunday District

Project info

The project will build southbound overtaking lanes at Kalarka Road and south of Carmila, and 1 northbound overtaking lane near Mosquito Creek. This will involve widening, drainage works and rehabilitation of the existing road. 

The overtaking lanes will be constructed simultaneously, reducing the overall duration of the project and minimising impacts to road users.

An average of 33 jobs will be supported over the life of the project.

Key milestones

  • November 2018: Tenders called for construction
  • February 2019: Tender award for construction
  • May 2019: Start of construction
  • March 2020: Project completion.
