Mitchell Freeway Southbound Widening - Cedric Street to Vincent Street

Mitchell Freeway carries some of the highest traffic demands in Perth, with up to 180,000 vehicles per day, and is a critical corridor connecting Perth’s northern suburbs to commercial, residential and recreational facilities in the wider metropolitan area.

The section of freeway from Cedric Street to Vincent Street is particularly congested in the morning peak, with bottlenecks at two separate locations where four lanes merge into three.

As part of a $2.3 billion investment in road and rail infrastructure, the State and Australian governments have committed $40 million to widen Mitchell Freeway between Cedric Street and Vincent Street, providing 7 kilometres of additional lane in the southbound direction to improve congestion through the area.

This work forms part of our overall plan to transform Perth’s freeways to accommodate population and economic growth into the future.

We value your feedback on how we are communicating with the community and invite you to complete a quick online survey.

Contruction update

Premier Mark McGowan, Minister for Transport Rita Saffioti and several dignitaries held a ground-breaking event for the project’s commencement on 14 October 2018. See the media release for more information.

Our Construction Update includes:

  • updated concept map
  • noise and screening walls
  • changes to traffic conditions
  • environment management
  • community engagement

Early works

Early works have commenced to locate services and do exploratory activities. This will require lane closures and speed reductions on Mitchell Freeway southbound between Cedric Street and Vincent Street. Short term works are also being undertaken on the freeway exits and entries between Reid Highway and Vincent Street. 

Upcoming dates:

  • Monday 15 to Friday 19 October from 8pm to 6am nightly
  • Sunday 21 to Friday 26 October from 8pm to 6am nightly

Users of the shared path near Vincent Street may experience delays during the daytime on Thursday 18 October.

Construction Reference Group

A Construction Reference Group has been formed, following a call for nomination in May 2018. The first meeting was held on 5 July 2018, with a second expected later in the year. The group has been formed to ensure adjacent communities have input into the project’s detailed design.

Scope of works

  • Build an additional 7 km lane on Mitchell Freeway southbound from Cedric Street to Vincent Street
  • Complete the missing link on the Principal Shared Path from Glendalough Station to Hutton Street
  • Improve median barriers between the railway line and traffic lanes with existing barriers being replaced with concrete barriers
  • Provision of noise and screen walls where required

Environment and community

We are committed to ensure early and ongoing communication is undertaken throughout the project to ensure you stay up-to-date. As the project develops from concept to detail design, more information will be available for our stakeholders.

While there will be some impacts during construction, we will plan to minimise disruption and inconvenience to road users and nearby residents as much as possible.

We invite you to complete a short online survey to provide feedback on how the project has been communicated.
