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.
Video: Smart Freeway Kwinana Northbound project 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.
Principal Shared Path (PSP)
Overnight works are progressing along the PSP between Canning Highway and Narrows Bridge. This section remains open between 5am and 8pm, Monday to Friday, and 7am to 8pm on weekends, with occasional day works scheduled outside peak hours (9am to 3pm) under traffic management.
Until mid-April, we will be installing permanent safety barriers along approximately 300 m of the PSP, between Canning Highway and the Cale Street footbridge (near the Scout Water Activity Centre at Como Beach).
At other times there may be local traffic management on the PSP between Farrington Road and the Narrows Bridge to allow for construction activities. Path users should observe traffic signage at all times and ride to the conditions.
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.
