Smart Freeways - Kwinana Northbound

We will deliver Perth’s first Smart Freeway and create an additional lane from Canning Highway to the Narrows Bridge. Smart technology will be used to open and close traffic lanes in the event of an incident and adjust speed limits to get more through traffic during busy periods.

Smart Freeways is the best solution for this constrained area where the railway and the Swan River prevent traditional widening. It will provide motorists with greater journey reliability, saving time, reducing costs and enhancing safety.

Construction and installation of Perth's first Smart Freeway is now just months away following the award of the project’s major contract.

The tender to construct an extra northbound lane on Kwinana Freeway and install smart technology was awarded to SmartWays Alliance.

The Alliance includes BMD Constructions Pty Limited, Ventia Pty Limited and Arup Pty Ltd, who will work with us under the contract arrangement.

Detailed design is underway and site investigations are expected to start in September, which may involve occasional lane closures and night works.

Scope of works

  • All Lane Running: creation of an additional lane by transitioning the emergency stopping lane for use by general traffic between Canning Highway and the Narrows Bridge.
  • Lane Use Management System: safely enabling all lane running by implementing a smart system to close and reopen traffic lanes, adjust speed limits and provide emergency access during incidents, similar to the system used in the Northbridge Tunnel. 
  • Variable speed limits: are used to improve traffic flow by adjusting the speed limits based on traffic volumes and conditions. 
  • Emergency stopping bays: will be provided at regular intervals for vehicles to use in case of breakdown or incident.
  • Coordinated Ramp Signals: will be installed at on-ramps to help balance the flow of traffic onto the freeway and improve merging at Farrington Road, South Street, Leach Highway and Cranford Avenue.
  • Comprehensive CCTV coverage: will be linked to our central Traffic Operations Centre
  • Driver information: will be better facilitated through electronic message signs on the freeway informing motorists of traffic conditions ahead in real-time

Smart Freeways are used successfully around the world to manage congestion, improve safety and get the most out of existing infrastructure.
