Roe Highway and Kalamunda Road Interchange

Due for completion in early 2021, one of the last signalised intersections on Roe Highway is being removed.

The intersection of Roe Highway and Kalamunda Road is heavily congested and has a higher than average number of crashes. It also reduces the efficiency of Roe Highway as a strategic freight route.

Almost 60,000 vehicles pass through this intersection each day, and up to 14 per cent of these are heavy vehicles. This upgrade will go a long way towards improving safety for residents in Kalamunda and the foothills of Perth.

This project involves:

  • Construction of a grade-separated intersection at the Roe Highway and Kalamunda Road intersection including a new bridge, two roundabouts and on and off ramps
  • Lowering Roe Highway to pass beneath Kalamunda Road. This will minimise noise and visual intrusion for the surrounding residential area
  • Creation of a shared path on the eastern side of the highway and on Kalamunda Road, with local links for pedestrians and cyclists. The path will then extend to Berkshire Road and complete a missing link in the Shared Path network along Roe Highway
  • New drainage, street lighting and other supplementary works
