Roe Highway and Kalamunda Road Interchange

Latest News

We are currently investigating several options for a bridged interchange to improve safety and efficiency at the intersection of Roe Highway and Kalamunda Road.

A preferred design concept will be selected by late 2017 and this will be finalised in early 2018 to allow the tender process to start.

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.
