What's happening

New Karrinyup Road northbound exit open

The Mitchell Freeway northbound off-ramp to Karrinyup Road has opened, relocating approximately 500 metres south of its previous location – view the traffic map below.

For road users travelling north, move into the left lane earlier to access the new exit – the next available northbound exit will be at Erindale Road.

Please adhere to the signs, plan ahead, and expect minor delays, especially during peak hours.

This change aims to improve access to Karrinyup Road and boost traffic flow along Mitchell Freeway between Hutton Street and Karrinyup Road.

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.
