Morning Traffic Overview

Commuters heading into the Perth CBD and surrounding inner-city suburbs this Friday, March 20, 2026, should prepare for several planned road closures and public transport adjustments. While major freeway arteries are currently flowing well, localized projects in East Perth, West Perth, and Crawley are expected to create localized bottlenecks during peak hours.

Major Road Closures and Works

Several key streets within the City of Perth are subject to full or partial closures today to facilitate infrastructure upgrades and the ongoing Cool Roads Program:

Additionally, various other roads in the East Perth area are restricted today as part of the Cool Roads surfacing initiative; these works are scheduled to conclude daily by 7:00 pm.
• West Perth: Walker Avenue is closed to all through traffic today. Commuters are advised to use alternative routes such as Hay Street or Kings Park Road to avoid delays.
