Perth’s first Smart Freeway contains an additional lane from Canning Highway to Narrows Bridge on the Kwinana Freeway.

Smart technology is 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.

It provides motorists with greater journey reliability, saving time, reducing cost and enhancing safety.
