Mitchell Freeway Extension

Hester Avenue to Romeo Road

Extending the freeway to Romeo Road to help you get around the northern suburbs faster and safer. Works will begin in early 2021.

Construction site for Mitchell Freeway extension

The extension of Mitchell Freeway is part of a group of infrastructure improvements, which will support the expansion of Perth’s fast-growing outer northern suburbs of Butler, Yanchep, Alkimos and Eglinton.

This project will extend a critical transport link and provide many benefits to the local community, including improved access and travel times.

As part of the Mitchell Freeway Extension, we will:

Extend Mitchell Freeway from Hester Avenue to Romeo Road, with two traffic lanes in each direction
Construct an interchange at Lukin Drive and widen the road to Connolly Drive
Connect Romeo Road from Wanneroo Road to Marmion Avenue
Construct signalised intersections along Romeo Road at the freeway, Benenden Avenue and Wanneroo Road
Upgrade Romeo Road intersection with Marmion Avenue
Upgrade the Hester Avenue interchange
Widen Wanneroo Road from south of Romeo Road to Trian Road
Construct a bridge or tunnel over Transperth's Nowergup Depot access road and realign to Hester Avenue
Construct a rail tunnel under the freeway north of Lukin Drive
Build a Principal Shared Path on the western side of the freeway
Build a fauna underpass at Romeo Road for the Yaberoo Budjara Trail
Construct a pedestrian underpass at Lukin Drive
Install noise and screen walls, safety barriers and lighting where required

Construction will take place at the same time as the Yanchep Rail Extension. This is part of the State Government's commitment to METRONET. It will ensure a coordinated program of works that delivers well-planned transport infrastructure for the northern suburbs and the wider metropolitan area. 

What's Happening

Community Consultation

Environment

Noise Walls

Noise monitoring and modelling has been undertaken and will determine the final design and location of noise walls adjacent to existing residential areas in line with State Planning Policy 5.4.

We will provide a noise wall along the western side of the freeway for its full length from Hester Avenue to Romeo Road. More information about wall heights and materials will be made available once the design has been finalised.

Sustainability

Our early work identified some key areas of focus for sustainability. We will consider the use of LED lighting and recycled materials in construction as we progress the design.

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.

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

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.

The following Native Vegetation Clearing Permits granted under Section 51C of the Environmental Protection Act 1986 (EP Act) from the Department of Water and Environmental Regulation to clear native vegetation for the project.

CPS 8753/2
CPS8826/1
CPS8861/2

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.

Environmental and heritage considerations

We completed flora, vegetation and fauna surveys during 2018 and 2019. These surveys helped inform the planning and design of the proposal.

During the clearing works, removal of vegetation will be undertaken in a progressive manner to allow fauna to relocate to the adjacent National Park. Fauna present on site that do not voluntarily move back into adjacent habitat will be relocated by a qualified fauna handler.

We also undertook Aboriginal and historic heritage surveys throughout 2018-19. Routes to avoid an Aboriginal site on Romeo Road are being investigated.

As part of the principal shared path design, we proposed strategic connections to the existing heritage trail within Neerabup National Park at Romeo Road and to Nowergup Lake Hike Trail at Wanneroo Road and Lukin Drive.
