Project update

Nicholson Road and Armadale Road intersection upgrade

The new roundabout and grade-separated bridge at the Nicholson Road and Armadale Road intersection is nearing completion, which will bring smoother traffic flow in an east-west direction.
See the October 2019 Construction Update for more information.

Completion of Taylor Road/Wright Road roundabout

The new Taylor Road/Wright Road roundabout at Armadale Road was opened to traffic on 9 September.

The existing four-way intersection has been converted to a two-lane roundabout to improve traffic flow and safety outcomes. The roundabout is currently operating in a temporary arrangement (one lane in each direction) until the dual lanes on Armadale Road are complete at the end of the year.
