Perth's newest smart freeway will be formally switched on, on Sunday, 22 December, providing commuters with faster and safer journeys.

More than 1,400 pieces of smart technology are being installed along the Mitchell Freeway southbound. Key features include overhead electronic signs and message boards, and coordinated ramp signals. The technology includes sensors and cameras to monitor traffic in real time 24/7.

Smart Freeways will provide motorists with greater journey reliability and improved safety by alleviating congestion at peak times and minimising stop-start conditions at merge points.

The technology has already had great success along the Kwinana Freeway northbound, with motorists continuing to experience a safer journey and saving up to 6 minutes on their journeys between Farrington Road and the Narrows Bridge during the morning commute.

This project links to the Stephenson Avenue Extension project, which provides a new connection from Cedric Street to Scarborough Beach Road. An interchange will be introduced at Mitchell Freeway with a southbound Smart Freeway on-ramp, as well as new local road links to Ellen Stirling Boulevard.
