Walkerston Bypass

The Walkerston Bypass will deliver a new 2-lane rural highway to connect Peak Downs Highway west of Walkerston to the Mackay Ring Road near Paget.

The new Walkerston Bypass will become the designated heavy vehicle route for B-double and other multi-combination vehicles, including A-double road trains, between the Bruce Highway and the Peak Downs Highway.
