Stephenson Avenue Extension

Phase One

Stephenson Avenue was extended from Scarborough Beach Road to Howe Street, including two new signalised intersections. This section was delivered by City of Stirling and opened to traffic on Friday 11 February 2022. Learn more on their website.

Phase Two

Stephenson Avenue will be extended from Howe Street to Mitchell Freeway and Cedric Street interchange.

Upgrades include:

• Stephenson Avenue grade separated interchange at Mitchell Freeway - Stephenson Avenue bridge over Mitchell Freeway and the Joondalup Line.
• New road connecting Sarich Court to Cedric Street on the west side of the freeway, including a new bridge for Stephenson Avenue.
• New shared path on the east side of Mitchell Freeway from Telford Crescent to Civic Place, including an underpass under Stephenson Avenue.
• New shared paths along Stephenson Avenue and connections to the new path along the freeway.
• Modifications to Mitchell Freeway and Cedric Street interchange, removing the southbound off and on-ramps and northbound off-ramp.
• New access to Stirling Station car park.
• Upgrade Stirling Bus Interchange from an 18-stand to 30-stand facility.

The project is part of the City of Stirling’s broader plan to transform the Stirling City Centre – an area bounded by Karrinyup Road, along Cedric Street and Ellen Stirling Boulevard to Scarborough Beach Road.

It will connect key activity hubs, including Westfield Innaloo Shopping Centre, the Osborne Park industrial area and the Stirling City Centre.

We’re working closely with Public Transport Authority for the Stirling Bus Interchange upgrade and Stephenson Avenue works. This will streamline the design and construction process minimising disruption to motorists, bus and rail passengers and the surrounding community.
