Cars driving along Tonkin Highway

Planning and development is well underway to upgrade Tonkin Highway south of Roe Highway. The project includes widening Tonkin Highway from four to six lanes and upgrading the intersections at Hale Road, Welshpool Road and Kelvin Road, improving safety and reducing delays along this heavily congested route. 

This important project will be delivered under two contracts. The first will include the intersections along Tonkin Highway at Hale Road and Welshpool Road, and the second includes Tonkin Highway and Kelvin Road.

What's happening

View our latest video animation which outlines the scope of the first contract. This involves widening Tonkin Highway and upgrading intersections at Hale Road and Welshpool Road to improve traffic flow.

We are also seeking your input into our survey, focusing on traffic-related matters, and how you travel to and from the area. Read our latest Project Update and have your say on our survey before 15 October. 

We are in the project development phase, which investigates and defines the project’s technical scope. This involves assessing the various options for both contracts, which includes the three Tonkin Highway intersections at Hale, Welshpool and Kelvin Roads.

We have undertaken a number of activities to confirm the project scope, including:

  • ongoing stakeholder consultation to identify and resolve various issues/constraints, including nearby landowners, community and environmental groups;
  • concept design, geotechnical and site investigations, traffic modelling and environmental assessments to inform environmental processes and approvals.
  • 2020-21: Planning and Development for both contracts
  • 2023: Construction commences
Construction timelines for both contracts are subject to environmental and statutory approvals, and finalisation of project scope
