Monday Commute Alert: Mandurah Line Nightly Closures and East Perth Roadblocks

Commuter Alert: Mandurah Line Disruptions and CBD Road Closures

Good morning, Perth. As we begin the work week on Monday, 16 March 2026, commuters should prepare for several significant disruptions affecting both rail and road networks across the metropolitan area. Whether you are heading into the CBD or traveling through the southern suburbs, planning ahead is essential to avoid delays during the morning and evening peaks.

Train Disruptions: Mandurah Line Night Closures

The most critical update for rail passengers today involves the Mandurah Line. To facilitate essential track maintenance, the line will be disrupted nightly between Cockburn Central and Mandurah. If you are working late or traveling this evening, please take note of the final full-line services to ensure you are not stranded:

• The last train from Perth Underground to Mandurah departs at 7:51 PM.
• The last train from Mandurah to Perth Underground departs at 8:25 PM.

Train replacement bus Route 909 will be in operation while trains are cancelled, including some express services to help mitigate travel times. However, passengers are urged to allow for at least 30 minutes of extra travel time. Please note that bicycles and large e-rideables are not permitted on replacement buses due to strict space constraints.

City Roadworks and Street Closures

Drivers navigating the inner city will face a series of new road closures starting today. Several major streets are undergoing maintenance or infrastructure upgrades that will impact local traffic flow:

• East Perth: Brown Street is closed to all traffic between 7:00 AM and 7:00 PM for the installation of electrical infrastructure. Additionally, various roads across East Perth will see daily restrictions from 9:00 AM to 7:00 PM this week as part of the ongoing Cool Roads Program.
• Perth CBD: Queen Street is closed today from 7:00 AM to 7:00 PM for the installation of temporary crossovers and hoarding. Wolf Lane is also closed for maintenance today and tomorrow.
• West Perth: Walker Avenue is closed for through-traffic starting this morning, with local diversions in place for residents and businesses.

Major Arterial Impacts: Fremantle and Tonkin Highway

A reminder for those traveling from the western suburbs: the Fremantle Traffic Bridge remains fully closed as construction continues on the new river crossing. This long-term project has significantly increased traffic volume on Stirling Highway and Canning Highway, so expect slower-than-usual conditions during the morning rush. Meanwhile, in the southeast, Tonkin Highway extension works are active near Thomas Road; motorists are advised to adhere to the posted 60km/h limits as heavy haulage vehicles are frequently crossing the main alignment.

Travel Advice

To ensure a smooth start to your week, we recommend checking the Transperth app for real-time replacement bus tracking. For those driving, avoid the East Perth precinct if possible, as the combination of the Cool Roads Program and infrastructure works on Brown Street is expected to create significant local bottlenecks throughout the day. Stay safe and patient on the roads this Monday.
