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.

Procurement for design and construction contract

The transformation of Mitchell Freeway is one step closer with a design and construction contract expected to be awarded in mid-2018 for the $40 million widening of one of Perth’s most critical corridors.

Seven kilometres of additional lane will be built between Cedric Street and Vincent Street to reduce congestion and bottlenecks for southbound traffic.

Construction will commence shortly after contract award.

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

The project involves building an additional 7 km lane on Mitchell Freeway southbound from Cedric Street to Vincent Street.

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.
