South Arm Highway to double in width under $55 million upgrade

South Arm Highway Upgrade

A $55 million upgrade will double the width of the South Arm Highway, adding two lanes to a congested stretch between Rokeby and Lauderdale.

The project will widen the highway from two to four lanes between Pass Road and Oakdowns Parade, with construction expected to begin in 2027.

Traffic modelling shows that without the new signals and lanes, residential and commercial growth over the next five years would lead to longer travel times and heavier delays.

Designs are now open for public feedback.
