Mitchell Freeway Extension

What's happening

Upcoming roadworks

After hours works

Out of hours works are required for kerb installation on Mitchell Freeway northbound, just north of the Hester Avenue off-ramp. The works are remedial works as part of the Mitchell Freeway Extension project.

Mitchell Freeway northbound verge, north of Hester Avenue off-ramp:

7pm Friday 27 September, to 5am Saturday 28 September
Lane closures
The works will be undertaken in the early evening on Friday, however, could carry over to the Saturday morning.

Due to traffic volumes and access required, the works are required to be undertaken outside of ordinary hours.

From 11 to 28 September 2024, there will be intermittent day and night time lane closures at these locations

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

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.

Environmental Approvals

We make every effort to minimise impacts on the environment. In December 2019, we sent the environmental proposal to the Commonwealth Department Agriculture, Water and the Environment

for approvals. These documents were available for public comment from February to March 2020.

In accordance with Section 95A(3) of the EPBC Act, the preliminary documentation for the proposed action was available for public comment from 13 February 2020 to 1 March 2020 inclusive. A total of 3 public submissions were received on the preliminary documentation.

In accordance with Section 95B(2) of the EPBC Act, the preliminary documentation and a summary of responses to the public submissions is now available.

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.
