What's happening

Cedric Street and Stephenson Avenue intersection weekend works – 10 to 13 July 2026

We are continuing the next stage of works at the Cedric Street and Stephenson Avenue intersection this weekend. Construction activities include profiling, asphalting, kerbing, paving, line marking and signals installation.

To safely complete these works while minimising impacts to road users and Transperth passengers, temporary traffic and access changes will be in place from 10pm Friday 10 July to 5am Monday 13 July.

Traffic changes

  • Traffic will be reduced to one lane in each direction through the Cedric Street and Stephenson Avenue intersection and surrounding approaches.
  • Speed reduced to 40km/h throughout the work area.

Stirling Station car park disruptions

  • The northern station car park will be closed for the duration of the weekend works.
  • Access to the southern station car park will remain available via Stephenson Avenue under a left-in, left-out arrangement only.
  • The right-turn from Stephenson Avenue westbound into the southern station car park will be temporarily unavailable.

Pedestrian detour

  • Pedestrian access between Cedric Street and Stephenson Avenue will be temporarily restricted during the works. Signage will be in place to help guide pedestrians to an alternative crossing route.

We understand that these disruptions may cause inconvenience to your journey and thank you for your patience while we undertake these important upgrades.

Cedric Street closed to mid-2026

We are progressing upgrade works to the Cedric Street intersection and will continue drainage, pavement and shared path construction, asphalting works, and signalised intersection tie-in works.

To safely complete these works the following traffic impacts will be in place until mid-2026:

  • Cedric Street closed in both directions between Stephenson Avenue and Ellen Stirling Boulevard.  
  • The right turn movement from Flax Way to Ellen Stirling Boulevard restricted to keep traffic moving through the detour routes while Cedric Street is closed.
  • The Cedric Street northbound on ramp remains closed - access to Mitchell Freeway northbound via the Stephenson Avenue northbound on-ramp or Karrinyup Road northbound on-ramp.

Buses and pedestrians will maintain access along Cedric Street to Stirling Station and associated car parks. There may be minor changes to route timings or stop locations – for more information on public transport disruptions, visit the Transperth website.

We thank the local community for their understanding and patience while these essential works are being completed.

Please plan ahead and allow additional travel time to your journey, especially during peak periods.

Missing Mitchell Freeway Principal Shared Path link opens

The new Mitchell Freeway Principal Shared Path connection between Civic Place and Telford Crescent is now opened.

The 1.4 km new four-metre-wide-path now forms part of the broader PSP network, improving safety, journey times and connections for people walking, riding and commuting in the area.

The path also features a new pedestrian and cyclist underpass with bespoke artwork under Stephenson Avenue.  

Local Western Australia artists David Ledger & Joanne Clark were inspired by Stirling’s market garden heritage and drew upon their personal connection to the area to develop A Patchwork of Stories.

Take a moment to enjoy the artwork as you pass through the new PSP connection.

Some finishing works continue on local shared path connections which will continue to open up in stages.
