​​​​​​​Smart Freeway - Kwinana Northbound

We are delivering Perth’s first Smart Freeway and creating an additional lane from Canning Highway to 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 traffic through during busy periods.

A Smart Freeway 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.

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

Project update

Shared Path closures

The current temporary shared path closure between Cale Street and the Narrows Bridge will remain in place until December 2019*. This is to allow for additional resurfacing of the path in several sections, and the lowering of existing manhole covers to pavement level, resulting in a safer and smoother journey.

Some minor realignment and resurfacing of the shared path is also required in several locations, to facilitate the installation of freeway gantries and installation of drainage and other works.

Detours are in place via Melville Parade, Judd Street and Mill Point Road. Normal road rules apply along detour routes. Please exercise caution, observe all warning signage and allow extra travel time when planning your trip​ -View the Detours PDF​ for more information.

We understand the detours are inconvenient and sincerely apologise for the ongoing disruption. 

Street Lighting

There is currently reduced street lighting on the freeway heading north between Canning Highway and the Narrows Bridge. Please take care and drive to the conditions.


  • Kwinana Freeway northbound from Farrington Road to the Narrows Bridge, including on-ramps
    • Intermittent lane closures and speed reductions from 8pm to 5am (excludes Fridays and Saturdays).

* Please note these dates are subject to change.

Community Engagement Survey

How are we doing? Please take a couple of minutes to complete our Community En​gagement Survey . The information collected will be used to inform how the Smart Freeway - Kwinana Northbound project team communicates with road and shared path users, businesses and community members.


  • All Lane Running: creation of an additional lane by transitioning the emergency stopping lane for use by general traffic between Canning Highway and 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 Road Network Operations Centre.

  • Driver information: will be better facilitated through electronic message signs on the freeway informing motorists of traffic conditions ahead in real-time.

This project is being delivered by SmartWays Alliance, which includes Main Roads, BMD Constructions, Ventia, and Arup.
