Smart technology will be installed along the Mitchell Freeway southbound, with coordinated ramp signals installed at 16 on-ramps from Hester Avenue to Vincent Street.

The technology has already had great success along the Kwinana Freeway northbound, between Roe Highway and the Narrows, with motorists saving up to 10-minutes during peak hour.

It will provide motorists with greater journey reliability, congestion relief and enable the freeway to operate more efficiently without stop-start conditions at merge points.

  • Improve the efficiency and safety of the freeway
  • More reliable journey times and provide congestion relief for more than 180,000 daily motorists
  • Reduced stop-start conditions by managing traffic flow
  • An investment in road infrastructure and state employment opportunities
