Stephenson Avenue Extension Project

Tenders have been called for phase one of the Stephenson Avenue Extension project - extending Stephenson Avenue from Scarborough Beach Road up to Sarich Court in Osborne Park. Follow project

Delivered over two phases, the extension project includes the construction of a new freeway interchange and the Stephenson Avenue Road Network that runs through the middle of 55 hectares of land-locked vacant land.

As well as opening up large areas of land for development, the project will reduce traffic along Scarborough Beach Road. Reducing traffic along Scarborough Beach Road will free up road capacity for the future construction of dedicated bus lanes and ultimately a light rail system.

Following a $60 million commitment by the Western Australian State Government and a $65 million commitment by the Federal Government, delivery is expected to commence in 2020 over two phases, with different agency responsibilities, City of Stirling and Main Roads WA:

  • Phase 1 Stephenson Ave, Scarborough Beach Road - Sarich Court (delivered by the City)
  • Phase 1A Sarich Court - Cedric Street (delivered by the City)
  • Phase 2 Freeway interchange (delivered by MRWA).

Once complete, the extension will provide a connection from Scarborough Beach Road to Cedric Street with a new Mitchell Freeway interchange.

The project is a key component of the Stirling City Centre project which will unlock private investment in the area, relieve traffic congestion, increase employment opportunities and support future light rail in this key CBD hub.

How is the extension being funded?

The Western Australian State Government is contributing $60 million and the Federal Government $65 million.

Will there be any disruption to my business during construction?

The work that will affect existing intersections will be done at night time or weekends to minimise disruption to business trade.

While some traffic lanes will need to be closed, traffic will be managed with detours and there will be controllers on site to help pedestrians cross roads during construction. There will need to be some night work at the intersection of Stephenson Avenue and Scarborough Beach Road to lay asphalt.

There should be no restrictions on parking, or access to business premises. Any dust caused will be carefully managed within the project site.

Construction Trucks can enter and exit the construction site via Sarich Court, Scarborough Beach Road, and the new Oswald/Howe Street links with Ellen Stirling Boulevard, and should not have any impact on business.

Will my building be damaged by the construction work?

Damage to buildings is highly unlikely. A ‘dilapidation survey’ will be carried out prior to commencement of any works to be conducted by a consultant ‘Specialist Testing and Technical Services Pty Ltd’ who will measure any possible damage and propose mitigation strategies.

What happens if works do damage buildings?

Damage incurred as part of the extension will be covered by the third party insurance policy of the main contractor.

When will the dilapidation survey happen?

The dilapidation survey is expected to commence February/March 2020. You will be contacted by the surveyor directly.

How will the City offset the trees and vegetation removed as part of the Stephenson Avenue extension project?

The City is committed to offset any tree loss on a 5:1 ratio by planting new trees in the close vicinity of the project. This means, for every one tree removed, five trees will be planted in its place. The City has already planted over 300 trees in and around the Stirling Civic Gardens, with additional trees to be planted along Stephenson Avenue as part of the Phase 1 construction works.
