​Roe Highway and Kalamunda Road Interchange

Roe Highway is part of a key road corridor linking Kwinana Freeway to Great Northern Highway, providing access to Kewdale, Hazelmere and Canning Vale industrial areas. Kalamunda Road is one of the last remaining signalised intersections on Roe Highway.

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.

Kalamunda Road is likely to flow over Roe Highway. This will minimise noise and visual intrusion for the surrounding residential area.

A shared path is included on the eastern side of the highway and on Kalamunda Road, with local links provided for pedestrians and cyclists.

New drainage, street lighting and other supplementary works will complete the interchange.
