Roe Highway Extension - Kwinana Freeway to Stock Road


Visit the South Metro Connect website for further information about the project.


Current Status

The Government of Western Australia is committed to the extension of Roe Highway from Kwinana Freeway in Jandakot to Stock Road in Coolbellup.

South Metro Connect, a team comprising personnel from both Main Roads and industry partner AECOM, is managing the project’s development phase, which includes:

  • Identification of a preferred concept design;
  • Investigation and assessment of the environmental, social and cultural impacts of the preferred concept design;
  • Project approvals processes; and
  • Ongoing community and stakeholder engagement.

It is anticipated that approvals and clearances required for construction to commence will be obtained in 2014. However, timing for construction is dependent on funding.



The extension will start at the existing Kwinana Freeway/Roe Highway interchange in Jandakot and head west along or near the existing Metropolitan Region Scheme road reserve for approximately 5 km, ending at Stock Road in the vicinity of its current intersection with Forrest Road, Coolbellup.

A preferred concept design has been developed through a comprehensive community and stakeholder engagement process conducted by South Metro Connect.

Strategic Review

A review was carried out to examine the strategic fit of the proposed Roe Highway Extension from Kwinana Freeway to Stock Road as part of the road transport network in Perth’s southern metropolitan area.

The findings of the review are available through the Roe Highway Strategic Review Report, October 2009.

Traffic volume forecasts contained in the report are based on the latest land use information available at the time of the study.

Subsequent forecasts, developed using updated land use information, may vary slightly from those shown in the report.


Community engagement

South Metro Connect has worked collaboratively with community and stakeholders to identify the most suitable design and alignment option within the project boundaries that will respect the local environment and still meet the growing traffic demands and associated social issues within the rapidly expanding southern corridor.

The highest levels of community and stakeholder engagement will continue to be maintained for the remainder of the project development phase to ensure sustainable outcomes are achieved through strong collaborative relationships.

Environmental Impact Assessment process

The Environmental Protection Authority (EPA) set the level of assessment for the project at Public Environmental Review (PER) with a 12 week public comment period.

The project was also referred to the Commonwealth Department of Sustainability, Environment, Water, Population and Communities (SEWPaC).

The EPA released the PER for the 12 week public comment period on 20 June 2011 with a closing date of 12 September 2011.

The EPA recommended conditional approval on 13 September 2013. Appeals closed on 27 September 2013 and are currently being assessed. A decision is expected from the Minister for Environment in early 2014.

Project objectives

Over the last decade the south metropolitan region has experienced extraordinary growth. This growth is set to continue with a number of significant projects scheduled.

Roe Highway Extension is proposed to be a significant east-west link in the south west metropolitan transport network, servicing a forecast demand of between 45,000 and 75,000 vehicles per day in 2031 – vehicles that would otherwise be using existing local roads

The extension aims to:

  • Complete the key strategic link in Perth’s road network which connects Reid Highway, Great Northern Highway and Great Eastern Highway in the Midland area to Tonkin Highway, Kwinana Freeway and Stock Road;
  • Improve the efficiency and ease traffic on parallel east-west roads such as South Street and Leach Highway, and also on Kwinana Freeway between Roe and Leach Highways;
  • Improve safety and reduce traffic congestion within the regional road network;
  • Provide better access for residents and road users in the cities of Cockburn and Melville to Kwinana Freeway, Bibra Drive, North Lake Road and Stock Road;
  • Improve access to the Murdoch Activity Centre, including the future Fiona Stanley Hospital;
  • Provide improved access to the Fremantle Inner Harbour;
  • Form part of the key freight route to the proposed Outer Harbour and the expanding Kwinana industrial area; and
  • Remove trucks from residential areas along Leach Highway between Stock Road and Kwinana Freeway, which will improve safety, reduce noise and improve the general amenity in this area.
