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. 

Roe Highway is being lowered to pass beneath Kalamunda Road. 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. The path will then extend to Berkshire Road, completing a missing link in the Shared Path  network along Roe Highway.

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