​Roe Highway and Kalamunda Road Interchange

The State and Federal Governments have allocated $86 million to build an interchange at the busy Roe Highway and Kalamunda Road intersection.

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 is part of a $2.3 billion package of road and rail infrastructure works, funded by the Australian ($1.6 billion) and State ($750 million) Governments.

Latest news

We have developed a planning concept and in early May 2018, Expressions of Interest were called from industry for a design and construction contract.

Once detailed design is complete, construction is expected to start in mid-2019. The new interchange should be completed in 2020.

See the June 2018 Project Update for more information.

Scope of works

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.
