Phase 2 of Stephenson Avenue Extension now underway

Work is now underway on Phase 2 of the Stephenson Avenue Extension, with the $165 million project set to provide a major boost to the local economy and support an estimated 800 jobs.

When complete, the project - being funded equally by the State and Federal governments - will provide a new connection from Cedric Street to Scarborough Beach Road, including a new grade-separated Mitchell Freeway interchange with a southbound Smart Freeway on-ramp, as well as new local road links to Ellen Stirling Boulevard.

The project will also deliver a $90 million refurbishment to the Stirling Bus Interchange, upgrading it from an 18-stand facility to a 30-stand bus interchange.

The Stephenson Avenue Extension Phase 2 project also includes:

  • A new road connecting Sarich Court to Cedric Street east of the freeway;
  • A new Principal Shared Path (PSP) on the east side of the Mitchell Freeway from Telford Crescent to Civic Place, including an underpass at Stephenson Avenue; and
  • New cycle and pedestrian paths along Stephenson Avenue and connections to the new PSP. 

Phase 2 is being delivered by the S2M Evolution Alliance, a consortium of Acciona, Clough and WSP under an alliance contract.

Stephenson Avenue Extension Phase 1, delivered by the City of Stirling, opened in February 2022 and has provided an alternative connection for motorists to access Ellen Stirling Boulevard and Scarborough Beach Road through new roads Howe Street and Oswald Street.
