Perth Traffic Update: Fremantle Bridge Detours and Nightly Rail Disruptions

Major Road Impact: Fremantle Traffic Bridge Closure

For commuters heading into or out of Fremantle today, Wednesday, 1 April 2026, the ongoing closure of the Fremantle Traffic Bridge remains the most significant disruption to local travel. Having been closed since February 1st for the construction of the new Swan River Crossing, drivers are reminded to continue using the Stirling Highway as the primary detour route. Heavy congestion is expected around Queen Victoria Street and North Fremantle, particularly during the morning and afternoon peak periods. Local authorities recommend allowing an additional 15 minutes for journeys crossing the river.

City of Perth and CBD Roadworks

In the heart of the CBD, several major closures are currently in place that may affect your morning commute. Telethon Avenue remains closed 24/7 between Milligan Street and Wellington Street to facilitate the installation of critical services; this closure is scheduled to remain in place until mid-May 2026. Additionally, Hale Street is closed between Waterloo Crescent and Nelson Crescent until Sunday to assist with school construction projects.

For those travelling late this evening, be aware that Sutherland Street will be closed southbound between Roe Street and Market Street from 7:30 PM tonight until 5:00 AM tomorrow. These nightly closures are necessary for anti-corrosion works on the rail bridge and are expected to continue through early May.

Public Transport: Nightly Rail Maintenance

Transperth has issued an alert for passengers on the Armadale and Thornlie-Cockburn lines. Tonight, Wednesday, 1 April, marks the final night of the current scheduled maintenance period for the section between Perth and Cannington. Nightly closures will begin at approximately 8:00 PM, with train replacement bus services (Route 907 and 908) operating until the end of service. Normal nightly train operations are expected to resume on Thursday evening.

Commuters on the Midland Line should note that while the new Midland Station is now fully operational, minor finishing works and landscaping are still occurring in the precinct. Access to the station remains unaffected, but pedestrians are encouraged to follow all directional signage around the new bus interchange.

Ongoing Infrastructure Projects

Motorists using Tonkin Highway in the south-east corridor, specifically near Byford and Armadale, should remain alert for ongoing heavy vehicle haulage operations. These works are occurring 24/7 as part of the Tonkin Highway Extension and Thomas Road Upgrade. In the coastal suburbs, finishing works including irrigation and landscaping continue at the intersections of West Coast Highway with Hale Road and Oceanic Drive. While lanes remain open, reduced speed limits are in effect to ensure the safety of workers on the verges.

Commuter Recommendations

• Check the Transperth app before 8:00 PM if you rely on the Armadale or Thornlie-Cockburn lines.
• Utilize the Stirling Highway as the designated alternative to the Fremantle Traffic Bridge.
• Plan for extra travel time if navigating the CBD near the Sutherland Street rail bridge tonight.
