Roe Highway and Kalamunda Road Interchange

Latest News

We are seeking expressions of interest from members of the community who are interested in joining a Community Reference Group for the Roe Highway and Kalamunda Road Interchange project.

This group will provide input as we complete the detailed design and construction of a bridged interchange at this busy intersection. If you wish to nominate for the CRG, please send an email stating your name, any organisation or special interest group you represent and your contact details.

We expect to finalise a preferred design concept for this project by late 2017 then continue with detailed planning in 2018.

Construction is scheduled to begin in early 2019 and be completed by mid-2020.

This intersection is one of the last remaining signalised intersections on Roe Highway, which is a strategic freight route. It is heavily congested, leading to a higher than average number of crashes.

$86 million has been allocated to this project, which is jointly funded by the Australian ($68.8 million) and State ($17.2 million) governments as part of a $2.3 billion investment in road and rail infrastructure.



This project will:

  • Reduce congestion on Roe Highway and Kalamunda Road
  • Improve safety and reduce journey times in Perth’s eastern suburbs
  • Enhance freight efficiency by allowing more efficient, reliable movements 
  • Improve safety for pedestrians and cyclists.



The project is currently in the planning phase to select a preferred concept. Once this is confirmed in late 2017, further project development activity will be undertaken to:

  • Define the project scope in consultation with stakeholders
  • Obtain the required project approvals and clearances
  • Develop a final concept design for the tender process
  • Identify land requirements and land acquisition

We will advertise for tenders in 2018 and award a contract in late 2018. Construction is scheduled to begin in early 2019 and be completed by mid-2020.
