Armadale Line Night Closures and Local Roadworks: Monday Traffic Update

Morning Commute Overview

Perth commuters are waking up to a relatively clear run on the major freeways this Monday, April 6, 2026. With the morning peak under way, current traffic flow is moving well on the Mitchell and Kwinana Freeways, though commuters should remain alert for ongoing barrier upgrade works that have narrowed some lane widths between Hodges Drive and Reid Highway. For those using the newly expanded METRONET lines, services on the Ellenbrook and Midland lines are running to schedule following the successful opening of the new Midland Station earlier this year.

Public Transport Alerts and Night Closures

While the morning train services are operating at full capacity, Transperth has issued a specific alert for the evening of Monday, April 6. The Armadale Line will undergo a scheduled night closure between Cannington and Byford to allow for essential track maintenance and infrastructure testing. Passengers planning to travel late tonight should prepare for the following disruptions:

• Armadale Line: Nightly closure between Cannington and Byford starting from approximately 8:00 PM. Replacement bus services will be in operation, but commuters are advised to allow an extra 20 to 30 minutes for their journey.
• Bus Route 452: A service disruption is currently in effect for Route 452, starting today and expected to last until Wednesday, April 8. Check the Transperth app for localized stop changes and minor timing adjustments.
• Midland Line: While the station is fully operational, minor finishing works and landscaping are ongoing near the shared paths. Please follow all directional signage around the new interchange.

Major Roadworks and Utility Disruptions

On the roads, several localized projects may cause minor delays throughout the day. Main Roads WA has confirmed that utility works and maintenance are scheduled at key intersections:

• Great Eastern Highway, Belmont: Expect lane closures and a reduced speed limit near the Daly Street intersection due to ongoing utility works. This may cause bottlenecks for those heading toward the airport during the afternoon peak.
• Reid Highway, Noranda: Maintenance works are scheduled for the westbound lanes at Malaga Drive. While much of this work is night-shifted (7:00 PM to 5:00 AM), some temporary barriers may remain in place during the day, requiring caution from motorists.
• Tonkin Highway Extension: Day and night haulage operations are continuing near the Thomas Road and South Western Highway sections. Be prepared for increased heavy vehicle movements around Shanley Road and Hopkinson Road.

Commuter Advice

As we head into the afternoon, the weather remains favorable for driving, but the evening train shutdown on the Armadale corridor will be the primary concern for south-eastern suburb commuters. We recommend heading off early if you rely on the Cannington to Byford section of the line. For those on the Kwinana Freeway, remember that ramp signals are active to manage merging traffic—ensure you keep a safe following distance as stop-and-go conditions can develop quickly near the Berrigan Drive exit.
