Armadale Road upgrade

Key Facts

Main Roads WA will be upgrading the 6.9km section of Armadale Road from Tapper Road to Anstey Road.

As this is the last section of the single carriageway between Kwinana Freeway and Armadale, the upgrade will provide additional lane capacity to improve safety and operational efficiencies in the area, along with better access and traffic flow.

The scope of the project has been broadened to include a grade separated interchange with Armadale Road passing over Nicholson Road. The interchange will allow east-west traffic on Armadale Road to flow freely, eradicating lengthy queuing and stop-start traffic conditions currently experienced on the approach to the intersection.

As this is a major project of Main Roads and works are not being carried out by the City,  please visit the Main Roads WA website here for more information including the full scope of works.
