Smart technology is being 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.

The key features of this project include overhead electronic signs and message boards, coordinated ramp signals and emergency stopping bays. 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.

Works on upgraded and new shared paths between Ocean Reef Road and Warwick Train Station are also underway.

The Smart Freeways project links to the Stephenson Avenue Extension, 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.
