Tonkin Highway Corridor

Roe Highway to Kelvin Road

  • New interchanges for Tonkin Highway at Kelvin Road and Welshpool Road, and a new flyover at Hale Road 
  • Planning and development now underway

 

Overview

We are planning to upgrade a critical section of the State’s transport network by widening Tonkin Highway from just south of Roe Highway to Kelvin Road from four to six lanes and to a freeway standard.

The project includes removing three sets of signalised intersections.

The preliminary concept for the project includes:

  • Upgrade Tonkin Highway from four to six lanes from Roe Highway to Kelvin Road
  • Construction of new grade-separated interchanges at the Tonkin Highway intersections with Welshpool Road and Kelvin Road
  • Construction of a flyover at Tonkin Highway and Hale Road

Project Update

Extensive planning and project development is now underway to confirm the scope and progress the various approvals to allow for construction.

Activities include:

  • stakeholder consultation to identify and resolve various issues/constraints 
  • concept design, geotechnical and site investigations, traffic modelling and environmental assessments to inform environmental processes and approvals
  • community engagement

Timeline

  • 2019-20: Planning and Development
