​​​​​​​​​​​​​​​​​​​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.

​Overview

  • 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.
  • Automatic Incident Detection systems, installed between Canning Highway and the Narrows Bridge, alert our operators to any incidents or breakdowns, while CCTV cameras allow further investigation.
  • 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.

Project update

Major project milestone

In early May we completed all freeway asphalt works, signaling a major milestone in the project. The construction activities left to complete include electrical installation testing and commissioning. Once these are finished, the technology required for the Smart Freeway to operate will undergo a rigorous testing process ahead of its deployment.

Principal Shared Path (PSP)

  • Canning Highway to Narrows Bridge closed 6 to 9  July from 7pm to 5am
  • Cale Street footbridge closed until asphalt works can be completed
  • Resurfacing and line-marking still to be completed in some areas, including the section near Cale Street footbridge
  • Occasional traffic management required between Farrington Road and Narrows Bridge.

Thank you for your patience.
