Contractor announced for Stephenson Avenue Extension – Phase 2

Monday, 1 November 2021

The contract for Phase 2 of the $165 million Stephenson Avenue Extension has been awarded to Acciona, Clough and WSP under an alliance contract.

When complete, the project will provide a new connection from Cedric Street to Scarborough Beach Road, including a new grade-separated Mitchell Freeway interchange to replace Cedric Street and local road links to Ellen Stirling Boulevard.

The Stephenson Avenue Extension Phase 2 project scope also includes:

  • A Smart Freeway southbound on-ramp;
  • A $90 million upgrade to the Stirling Bus Interchange from an 18-stand facility to a 30-stand bus interchange;
  • A new road connecting Sarich Court to Cedric Street west of the freeway, including a new bridge for Stephenson Avenue over the new road;
  • A new Principal Shared Path on the east side of the Mitchell Freeway from Telford Crescent to Civic Place, including an underpass under Stephenson Avenue; and
  • New shared paths along Stephenson Avenue and connections to the new Principal Shared Path.

Phase 2 is being delivered by Main Roads and major works are expected to commence early 2022 with completion in late 2023.

Phase 1 of the Stephenson Avenue Extension is being delivered by the City of Stirling and is expected to be completed by the end of this year.

Major works underway include:

  • Extension of Stephenson Avenue from Scarborough Beach Road through to Howe Street;
  • New local road connections between Stephenson Avenue and Ellen Stirling Boulevard at Oswald Street and Howe Street;
  • On-street parking; and
  • A new shared path for pedestrians and cyclists.

The project will support the local economy, creating an estimated 800 jobs over both phases.

The Stephenson Avenue extension and Stirling Bus Interchange projects are jointly funded by the Morrison Government and State Governments, with each contributing $127.5 million.

The Stephenson Ave extension is being funded under the Morrison Government’s Urban Congestion Fund.



Comments attributable to Federal Minister for Communications, Urban Infrastructure, Cities and the Arts, the Hon Paul Fletcher MP:

“The Morrison Government is getting on with delivering infrastructure projects that improve congestion and safety for commuters across Australia, making it easier for them to move around our capital cities and ensuring they get home quickly and safely.

“Under the Urban Congestion Fund, we are delivering 182 packages of work nationwide. The total number of projects that are now completed or underway nationwide is 73. A further 30 are expected to start construction this year.

“This is just the latest example of us delivering on our commitment to progress critical infrastructure projects across the country under our record $110 billion, 10-year infrastructure investment pipeline, which is helping to drive Australia’s economic recovery.”

Comments attributable to Western Australian Minister for Transport and Planning, Rita Saffioti:

“The Stephenson Avenue Extension is the first stage of the City of Stirling’s vision to open up 55 hectares of developable land and transform the area into the Stirling City Centre – a lively hub that will be home to 30,000 residents and 25,000 jobs.

“This project will improve access to important commercial and residential hubs, as well as providing key road, public transport, walking and cycling links for residents and businesses.

“When complete, this project will ease congestion and travel times, meaning less time on the road and more time with friends and family.”

Comments attributable to Federal Member for Stirling, Vince Connelly MP:

“This result is a massive win for Stirling residents. The Morrison Government’s investment in this project will help deliver more local jobs, improve amenities, and create a vibrant community.”

“Not only will this project ease traffic congestion, but it will also unlock large areas of land for new commercial development, helping the City of Stirling achieve its vision for a second CBD outside of Perth.”

Comments attributable to State Member for Balcatta, David Michael MLA:

“Phase 2 works of the Stephenson Avenue extension is a significant project that will help to make the Stirling City Centre a more vibrant place, and ease traffic congestion through this area.

“For people that commute through this area and catch public transport, these works will transform the way they commute, and make travelling through this area much easier.

“It’s also really exciting to see Phase 1 of the Stephenson Avenue Extension nearing completion, which will help improve the way people commute through the local area.”
