Smart Freeways - Kwinana Freeway 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.

Latest News

After receiving a number of expressions of interest from industry, potential contractors have been shortlisted for the $47 million Smart Freeways project to provide a more efficient Kwinana Freeway.

The shortlisted contractors Intelligent Transport Alliance (CPB Contractors Pty Ltd, Lendlease Services Pty Ltd, Jacobs Group (Australia) Pty Ltd and SICE Pty Ltd), Perth Smart Alliance (Georgiou Group Pty Ltd and WSP), and SmartWays Alliance (BMD Constructions Pty Ltd, Ventia Pty Ltd and Arup Group) have been invited to submit proposals by March 2018, with construction expected to start in late-2018.

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.
