What's happening
For an update on the project, check out the video below:
The Stirling Bus Interchange, adjoining Stirling Station and the Mitchell Freeway, is undergoing a major upgrade. You can find out more information on the PTA webpage.
These construction works will change how you navigate your way through the car parks and to the station.
We understand these works may add to your journey time and we will regularly review our signage and detour routes to deliver the fastest and safest station entry and exit routes.
The works are being managed by the S2M Evolution Alliance on behalf of Main Roads and the Public Transport Authority. Questions, feedback or concerns regarding the works should be directed to the 24/7 project information line on 138 138 or email enquiries@mainroads.wa.gov.au.
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.
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.
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.
A comprehensive high level sustainability target framework has been developed to manage our impacts on the local environment. We have considered sustainability topics relevant to the project and the United Nations Sustainability Development Goals (SDGs).
The sustainability targets align with the Infrastructure Sustainability (IS) Ratings Scheme administered by the Infrastructure Sustainability Council (ISC).
Have your Say!
In August 2023 we undertook a community survey to evaluate how effective our communications are in reaching the local audience, our approach to managing construction impacts and how you want to receive information from us. The feedback has been received, find out more by reading the Engagement Summary.
We engage regularly with key stakeholders including the City of Stirling, PTA, Transperth, Traditional Custodians, nearby businesses and local residents, as well as service providers and other government agencies that are involved.
We acknowledge the significance of this area for the Traditional Custodians, and we continue to engage with their representatives. Part of this involves the development of public art concepts. In January we undertook a community survey to gather feedback on our Approach to Public Art. We look forward to sharing the outcome with you very soon as a part of our second round of engagement.
A third community survey will be undertaken to influence landscaping plans.
