Smart Freeway - Mitchell Southbound

Hester Avenue to Vincent Street

Planning is underway to upgrade Mitchell Freeway southbound from Hester Avenue to Vincent Street. Major upgrades include coordinated ramp signals and Smart Freeway technologies.
Smart Freeway - <em>Mitchell Southbound</em>

With more than 180,000 daily motorists, Mitchell Freeway southbound is at capacity. Traditional solutions to alleviate congestion such as adding more lanes is not possible along this 36 kilometre stretch of freeway due to the constrained areas both along the verge and the median/rail line.

We’re planning to modify each of the 16 freeway on-ramps with co-ordinated signals from Hester Avenue to Vincent Street, and Smart Freeway technologies at key locations closer to the Perth CBD as part of a more cost effective, sustainable solution.

Coordinated ramp signals will receive continual traffic data on freeway conditions from sensors under the road surface. The smart technology will use the data to determine how much to vary the on ramp signal timings, enabling vehicles to enter the freeway and merge safely, whilst working in coordination with other on ramp signals to enable efficient traffic flows.

As part of this project, we’ll also be:

  • Installing CCTV cameras to enable continual traffic monitoring and management.
  • Realigning the Principal Shared Path adjacent to freeway on-ramps where it may be impacted by the works.
  • Installing or replacing safety barriers at on-ramps where required.
  • Undertaking resurfacing and line marking where required.
