What's happening
Permanent closure of the temporary Cedric Street southbound off-ramp – from 9pm, 14 November 2025.
We are progressing key construction works to complete the future Stephenson Avenue southbound off-ramp. To enable the safe construction of the tie-in with Mitchell Freeway, we are required to close the Cedric Street southbound off-ramp ahead of the new off-ramp opening.
Once the Cedric Street southbound off-ramp is closed, we will be working 24/7 to minimise the timeframe the ramp is closed and therefore disruption to traffic.
Based on current schedules the new southbound off-ramp at Stephenson Avenue will open in early December.
Access to Innaloo, Stirling and surrounding areas will temporarily be via the following alternative routes until the new Stephenson Avenue southbound off-ramp is operational:
- To access Innaloo and northern Stirling - exit earlier at the Karrinyup Road southbound off-ramp.
- To access Osborne Park and southern Stirling – exit later at the Hutton Street southbound off-ramp.
If you also regularly use the Stirling Station northern car park, access into the car park will be maintained via Cedric Street only, with no changes to how you exit the car park.
We understand that these disruptions may cause inconvenience to your journey and thank you for your patience while we undertake these important upgrades.
Signage will be in place to support these changes, and we encourage you to allow additional time to your travel journey, especially during peak periods.
