​​​​​​​​​​​​​​​​​​​​​​​​​Mitchell Freeway Extension

Hester Avenue to Romeo Road

Overview

We are planning for the future extension of Mitchell Freeway - creating a high standard north-south transport link in Perth's north western suburbs. A reservation for the freeway extension has been included in the Metropolitan Region Scheme (MRS) for a number of years.

This extension is part of a suite of transport infrastructure improvements designed to support the expansion of Perth's fast growing outer northern suburbs. It will alleviate pressure on the local road network, reduce travel times and improve safety and connectivity for people living and working in the region now and into the future.

The preliminary concept includes:

  • A 5.6 km extension of Mitchell Freeway from Hester Avenue to Romeo Road with two traffic lanes in each direction and provision for future widening
  • Completion of the interchange at Hester Avenue
  • New interchange at Lukin Drive
  • A rail tunnel or bridge for the existing rail to exit the freeway median to Butler station
  • A new principal shared path for cyclists and pedestrians on the western side of the freeway from Hester Avenue to Romeo Road
  • Constructing and connecting Romeo Road between Marmion Avenue and Wanneroo Road
  • Noise mitigation, street lighting and safety barriers where required
  • Duplication of Wanneroo Road for 1.8 km from Romeo Road to Trian Road
Construction will be aligned to complement the Yanchep Rail Exte​nsion - part of the State Government's commitment to METRONET - to ensure a coordinated program of works that delivers well planned transport infrastructure for the Northern suburbs and the wider metropolitan area.

Environmental assessment and approvals

In December 2019, we referred the Mitchell Freeway Extension Hester Avenue project and associated Wanneroo Road upgrade to the Commonwealth Department Agriculture, Water and the Environment (DAWE) under the Environmental Protection and Biodiversity Conservation Act 1999As the proposal was considered to have a significant impact on Matters of National Environmental Significance, we prepared a range of information (Preliminary Documentation) to inform the assessment by DAWE.

Preliminary Documentation are required to be published and made available for public comment for a minimum of 10 business days, during this time any third party can comment on the proposal.

The comment period is open until Sunday 1 March 2020.​ The information is available in the documents below:

January 2020 Update

Extensive planning and project development is now underway to progress approvals to allow for construction to commence later this year. 

Activities include:

  • stakeholder consultation to identify and resolve various constraints/issues
  • concept design, geotechnical and site investigations, traffic modelling and environmental assessments to inform environmental processes and approvals
