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 through traffic 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

Community Engagement Survey

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

Path closures

To facilitate construction activity, the following sections of shared path along Kwinana Freeway will be temporarily closed for the safety of cyclists, pedestrians, road users and our workforce:

Between Cale Street Footbridge and Hardy Street Footbridge until mid-August with detours via Melville Parade.

From mid-June, the closure will extend north to the Narrows Bridge with detours via Melville Parade and Mill Point Road.

The two detours have been planned to minimise disruption and allow time for works on and around the shared path. This includes lowering existing manhole covers to pavement level, resulting in a safer and smoother journey. Some minor realignment of the shared path is also required in several locations, to facilitate the installation of freeway gantries and installation of drainage and other works.

Normal road rules apply along detour routes. Please exercise caution, observe all warning signage and allow extra travel time when planning your trip.

Roadworks

  • Kwinana Freeway from Farrington Road to Canning Highway, and connecting arterial roads
    • Intermittent northbound lane closures and speed reductions from 22 May to 29 May, 8pm-5am (week nights) for geotechnical investigations
  • Kwinana Freeway northbound entry from Canning Highway
    • Closed on 5 June from 8pm to 5am for the installation of construction barriers
    • Detour in place via Canning Highway, South Terrace, Labouchere Road and Mill Point Road
  • Kwinana Freeway northbound entry to Farrington Road, South Street, Leach Highway and Cranford Avenue
    • Intermittent lane closures and speed reductions from late-June to August, 8pm to 5am. Works including drainage, barriers and gantry/sign footings

Please note these dates are subject to change.

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.

  • 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.
