Mitchell Freeway Extension

What's happening

After-hours works

As part of the Mitchell Freeway Extension from Hester Avenue to Romeo Road finishing works, a weed spraying program will be conducted throughout the project site over the month of May 2024.

Night works are scheduled from 13 to 16 May in the Mitchell Freeway medians and verges to minimise impact to road users and for the improved safety of the crews conducting the works.

Monday 13 May 7pm to Tuesday 14 May 6am

We apologise in advance for any disturbance and inconvenience caused by these works.

Alkimos, here we come!

The Mitchell Freeway Extension from Hester Avenue to Romeo Road opened to road users on 10 July 2023. It includes:

New freeway access points at Hester Avenue, Lukin Drive, Butler Boulevard and Romeo Road.
New east-west link with the extension of Romeo Road from Wanneroo Road to Marmion Avenue.
The duplication of Wanneroo Road from Romeo Road to Trian Road.
New footpaths, shared paths and Principal Shared Paths, including underpasses.
A new bridge over the Butler railway

Finishing works and road works

Road users will notice construction activities on Romeo Road will continue beyond the extension opening. These works are required to create road connections for future developments north and south of Romeo Road. Intermittent lane closures and traffic management will occur along Romeo Road for the duration of these works. The ongoing works also include landscaping.

Testing and commissioning of new traffic signals along Romeo Road at Benenden Avenue will continue, with traffic signals operating under temporary configurations until the commissioning process is concluded.

Working with the METRONET Yanchep Rail Extension

The Project received 560,000 cubic metres of material from METRONET’s Yanchep Rail Extension, which created cost savings for both projects, as Yanchep Rail Extension avoided having to store excess material on site or private land, and Mitchell Freeway Extension Project minimised its need to acquire material from external sources.

The material was used to undertake earthworks for the future Romeo Road freeway interchange (to be constructed as part of a future freeway extension).

This agreement significantly reduces the carbon emissions associated with transporting material from across the Perth Metropolitan area.

A more sustainable road network

The project has supported Main Roads in meeting its long-term commitment to deliver a more sustainable road network. Highlights include:

Installed LED lighting on the freeway and Principal Shared Path (PSP) to improve energy efficiency, lighting output, asset longevity, and to reduce maintenance costs.
A 20kw solar panel system was installed on the project office roof, which provided most of the office’s power needs over a two-year period, along with power for two electric vehicles.
Used more than 2.5 million tonnes of recycled materials, including 22,992 eco-blocks created from local recycled construction waste, including crushed recycled concrete. The eco blocks were used in the project’s noise walls.
Accepted approximately 560,000 tonnes of surplus material from METRONET's Yanchep Rail Extension project to support future works and freeway expansion.
Exported surplus limestone to the Ocean Reef Marina project for reuse in the marina development.
Moved approximately 3 million tonnes of earth across the site to raise and lower ground levels. This eliminated the need to export and import material from the project site.
Achieved an independently verified silver sustainability rating for design, using the Infrastructure Sustainability Council’s Rating Tool 2.0.

Environment and Sustainability Management

A comprehensive sustainability framework was developed to manage the project’s impacts on the local environment.

To enable future proposed extensions, an amendment was submitted to the Metropolitan Region Scheme to Environmental Protection Authority (EPA), reserving the proposed freeway Corridor. In 2003, approval was granted under Division 3 of Part IV of the EP Act. This approval (Ministerial Statement 629) covers part of the project.
