What's happening
We are continuing drainage installation to connect Sarich Court to the future Stephenson Avenue, west of the freeway and from Tuesday 3 June to Monday 30 June 2025 from 8pm to 4am we will be relocating a section of fencing along the western end of Sarich Court.
Works include trenching, excavating and backfilling to safely install concrete pipes using equipment and machinery including excavators, trenchers, trench boxes, trucks and lighting towers.
To allow works to be completed safely, we will need to close a section of Sarich Court at night, traffic management will be in place. As heavy machinery will be operating in the area and traffic conditions will change, we recommend vehicles do not park overnight along Sarich Court until these works are complete (please refer to below map).
All works are subject to favourable weather conditions and workforce availability.
We understand construction impacts may cause some disruptions and inconvenience to nearby businesses.
After-hours access for some businesses may be disrupted during our works. However, every effort will be made to reduce impacts where possible.
If you have any concerns during the works, please contact 138 138 (24 hours).
To stay up to date with the project, subscribe to email notifications.
We also have a 24/7 project information line that can be contacted on 138 138 or email enquiries@mainroads.wa.gov.au and a project team member will get in contact with you.
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.
Stirling Station – Southern car park disruption
In October 2024, a section of the southern car park at Stirling Station and motorbike shelter was closed to safely commence upgrade works to the car park.
From 5 February 2025, the remaining section of the Stirling Station southern car park will be completely closed to continue upgrade works to the car park.
Passengers are encouraged to take a break from driving by catching a bus to the station instead. To plan your journey, visit transperth.wa.gov.au.
ACROD parking, Drop Off – Pick Up bays, and short-term parking will continue to remain accessible in the eastern section of the southern car park during works.
Alternative temporary parking will continue to be provided for public transport passengers at 3 Tassels Place and additional parking will be provided at 7 Sunray Drive, Innaloo, west of the station – refer to map below. Please allow for additional travel time to Stirling Station if parking in these car parks.
There will be no disruption to the northern car park. Passengers with reduced mobility are encouraged to park there.
Please follow all signage during the work.
Access to the southern car park will be via Stephenson Avenue once the work is complete.
The timing of the work is subject to favourable weather conditions and workforce availability.

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.
In June 2024 Main Roads implemented asbestos management measures on the project’s stockpile site.
We are continuing to work with an independent contaminated sites auditor and the Department of Water and Environmental Regulation (DWER) on the ongoing management of the site.
The below outlines the updates provided.
- 14 June 2024 – Asbestos management measures implemented
- 26 June 2024 – Staged recommencement of works
- 11 July 2024 – Asbestos management update
- 22 August 2024 – Asbestos management update
- 25 October 2024 - Removal and relocation of stockpiled materials from site
Update 25 October – Stephenson Avenue Extension Project Asbestos Management
The S2ME Alliance will shortly be removing a significant volume of stockpiled material from the stockpile areas to a suitably licenced offsite waste facility. It is expected the removal of the material will be undertaken from late October 2024 until late December 2024.
The project is working closely with a Contaminated Sites Auditor (CSA) and relevant government agencies to ensure the removal of stockpiled material is undertaken safely and poses minimal risk to the community and the workforce.
Material will be removed from the stockpiles by loaders and loaded into trucks for transportation to the licenced facility.
Appropriate safety and risk management measures will be followed to protect the community and workforce during the movement and disposal of the stockpile material, by licensed waste carriers. Measures include:
- Regular application of water or dust suppression polymer on the material
- Ongoing washing of tyres / wheels
- Ensuring loads are covered prior to truck movement on local roads
- Road sweepers placed on standby should material be tracked onto the local road network
- Ongoing monitoring of dust and airborne asbestos fibres
Haulage vehicles will take the most direct route in order to minimise the distance travelled on local roads and through residential areas.
Removal of the materials will occur Monday to Saturday from 7am to 7pm in accordance with a City of Stirling-approved Noise and Vibration Management Plan. Nearby residents may notice an increase in trucks accessing local roads.
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.
