A major traffic incident has brought Perth's morning commute to a grinding halt after a serious crash shut down a critical section of the Mitchell Freeway.

The collision occurred on the northbound carriageway near the Powis Street and Southport Street ramps in Wembley. As one of Western Australia's primary north-south transport arteries, the closure has triggered severe, widespread disruption across the city's road network during the busiest travel hours of the day.

The Crash Scene: Emergency Response and Lane Closures

Immediately following the incident, a massive emergency response was initiated. WA Police, ambulance crews, and Incident Response teams from Main Roads Western Australia were dispatched to secure the site and assist those involved.

Current Operational Status:

The right lane of the northbound freeway remains closed to all traffic.
Paramedics are actively assessing and treating individuals at the scene; official injury figures and the exact number of vehicles involved have not yet been released.
Heavy tow trucks are on-site attempting to clear the wrecked vehicles and resulting debris.

Authorities have issued strict safety warnings for drivers approaching the area, mandating reduced speeds and strict adherence to traffic control directions to protect emergency workers operating on the active freeway.

Gridlock: Congestion Reaches the Perth CBD

The sudden bottleneck has caused severe ripple effects for northbound commuters. As vehicles are forced to merge off the freeway at earlier exits to avoid the closure, the resulting gridlock has backed up for kilometers.

Local traffic updates indicate that bumper-to-bumper congestion now stretches all the way back to Hay Street within the Perth CBD. Commuters are experiencing extremely slow travel times, with stationary traffic significantly delaying both personal vehicles and public transport bus routes utilizing the freeway corridor.

Main Roads Western Australia has cautioned that even after the lanes are officially reopened, the residual congestion will take a significant amount of time to clear.

Urgent Detours and Alternate Routes

With the Mitchell Freeway operating at a near standstill north of the crash site, traffic authorities are pleading with road users to avoid the area entirely. For those who must travel northbound this morning, the following detours are strongly recommended:

Reid Highway: Utilize either the eastbound or westbound routes to bypass the central freeway corridor entirely.
Mounts Bay Road / Riverside Drive: Use these link roads to access or exit the city center while avoiding the primary freeway chokepoints.
Local Subiaco & West Perth Roads: Navigate through the local suburban grid to bypass the Wembley section of the freeway, though these roads are also experiencing heavier-than-normal overflow traffic.

Motorists are advised to utilize real-time GPS navigation apps before departing and to allow for significant extra travel time.
