Construction of an interchange at the Roe Highway and Kalamunda Road intersection is complete and includes a new bridge, two roundabouts and on and off ramps.

The intersection previously suffered from heavy congestion and had a higher than average number of crashes. This upgrade will assist in improving road safety for residents in Kalamunda and the foothills of Perth.

The project also removed one of the last signalised intersections on Roe Highway.


  • Reduced traffic congestion
  • Improved road safety
  • More efficient, reliable movement of freight
