Mitchell Freeway Extension

Vegetation clearing

In early May 2021, we will begin the removal of vegetation in the road reserve between Hester Avenue and Romeo Road and between Romeo Road and Marmion Avenue. The clearing is necessary to extend the freeway and construct the Principal Shared Path, local roads and noise walls.

Vegetation has been assessed and strict clearing permits and approvals have been issued by the relevant authorities. Read more in the Environmental Management and Sustainability Fact Sheet (Word document, 875 KB).

Installation of fauna fencing and track closures

Fauna fencing will be installed on the eastern side of the road reserve to prevent larger animals from straying into the work site. Fencing the road reserve is necessary to prevent unauthorised access during the works and to ensure a safe distance is maintained between the community and construction machinery.

Once the road reserve is fenced, public access to existing informal tracks will be removed. This includes tracks in the following locations:

• East-west tracks between Romeo Road to Marmion Avenue
• North-south tracks between Hester Avenue and Romeo Road

In addition to the closure of informal tracks, the project is negotiating with the Department of Biodiversity, Conversation and Attractions to realign a small section of the Yaberoo Budjara Walk Trail in the Neerabup National Park. Access through the National Park will be maintained at all times. Read more in the April 2021 Track Closure Construction Update (Word document, 671 KB).

Project works depot establishment

During April and May 2021, depots are being established at the eastern ends of Butler Boulevard and Lukin Drive in preparation for the start of construction works. The depots will typically operate from 6am to 7pm and occasionally during scheduled night works. Read more in the April 2021 Construction Update (Word document, 584 KB).

Design and early works

Detailed design is underway and investigative works are being undertaken on site to locate utilities, complete geotechnical investigations and undertake surveying. Read more in the April 2021 Project Update (Word document, 2.11 MB).

Noise wall consultations

Noise walls will be constructed as part of the project between Hester Avenue and Romeo Road. Noise monitoring has been undertaken to determine the locations and heights of noise walls, in line with State Planning Policy 5.4.

Residents who will have a wall installed on their rear boundary will receive individual notifications.

Community survey results are now available

In August 2019, we invited the community to participate in a survey about the Mitchell Freeway Extension. See the results in our community consultation report.

Participants were most interested in the new freeway access points, travel-time savings and enhanced access to residential areas.

Most respondents said they would like to be updated via email or by visiting this project webpage. If you would like subscribe for email updates, visit our subscription page.

We will continue to engage with residents, local businesses and special interest groups to identify any concerns or issues as we move forward.

Construction Reference Group

A second Construction Reference Group meeting was held on 4 March 2021 – Meeting Minutes (PDF, 247 KB). 

• Collaboratively inform the planning and development process for the project
• Assist with the identification of, and responses to, project issues and opportunities identified by project stakeholders to ensure an optimal solution
• Provide a conduit for two-way communication and stakeholder input
• Communicate matters to and from respective organisations, groups and committees

We are using strategies to give local businesses every opportunity to take part in construction. We’re also challenging contractors to offer sustainable options in materials sourcing and supply.  

Noise walls will be constructed using cream Eco-Blocks; a key sustainability initiative for the project. These blocks are made from crushed limestone and recycled crushed concrete to deliver a high-quality product with similar appearance to reconstituted limestone blocks.

Electric Vehicle Trial

We are supporting the shift to Electronic Vehicles (EV) for use on the state road network and have nominated the Mitchell Freeway Extension Project to take part in a pilot trial.

The trial aims to test the commercial approach and understand any unforeseen issues that could arise through the introduction of a policy to implement a similar style quota for other Projects. If successful, a quota will be incorporated into further major Projects to support a wider Western Australian EV Strategy currently under development.

Environmental Approvals

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.
