A key stretch of the Mitchell Freeway north of Perth’s CBD is shut, sending thousands of motorists onto suburban streets and slower coastal routes. The closure followed a serious morning crash during the peak, with drivers warned to expect heavy delays and a lengthy detour. Commuters described a sudden standstill as emergency services moved in and traffic advice spread across radio and social media.
What Happened During the Morning Peak
Initial reports point to a multi-vehicle collision just after the rush began, sparking immediate lane closures and a full shutdown for safety. Police and Main Roads crews are investigating while tow operators and clean-up teams work to clear debris. “We urge motorists to avoid the freeway and follow official detour signs,” a Main Roads WA alert stated.
Witnesses spoke of a chain of hard braking before a loud impact, followed by drivers stepping out to check on those involved. “It went from flowing to frozen in seconds,” said one commuter stuck near an on-ramp. St John paramedics were seen moving quickly between vehicles, with officers diverting lanes to protect the scene.
Where Traffic Is Being Diverted
With lanes sealed off, traffic controllers are moving vehicles toward major arterial roads. Digital signs and navigation apps now recommend using parallel corridors to bypass the shutdown. Authorities advise patience and spacing, noting that popular alternatives are fast becoming congested.
- Consider Marmion Avenue for a coastal route, Wanneroo Road for an inland option, and Reid Highway or Ocean Reef Road to cross east–west; if possible, shift to public transport or delay departure.
Local intersections are bearing a load they weren’t designed to carry at this hour. Buses on nearby routes are experiencing knock-on delays as traffic signal cycles struggle with volume. “Expect extended travel times and plan for extra fuel,” authorities warned in a mid-morning update.
Delays Ripple Across the Northern Suburbs
The closure is sending shockwaves through suburbs from Innaloo to Joondalup, with minor crashes and breakdowns compounding the slowdown. Some drivers are cutting through quiet streets, creating pinch points near schools and shopping hubs. “Please keep speeds down and watch for pedestrians,” a local ranger urged.
Businesses report late deliveries and postponed appointments as staff attempt to reroute. Ride-share fares have surged, with drivers declining pickups in the busiest pockets. On social media, travelers share screenshots of blood-red traffic maps and plea for any shortcut still moving.
Safety Reminder After a Chaotic Morning
As responders work the scene, officials are using the moment for a safety reset. “Crashes of this scale are a stark reminder to leave space, stay alert, and avoid phone distractions,” said a road safety advocate. Drivers are urged to keep emergency lanes clear and follow on-site directions without argument.
If your vehicle begins to overheat in stop–start traffic, pull over safely and signal for help. Keep hazard lights on, lift the bonnet if safe, and remain inside with seatbelts fastened until assistance arrives. “The goal is to avoid a secondary incident that puts more people at risk,” the advocate added.
When Will Lanes Reopen?
There’s no firm timeline for reopening, with investigators assessing crash dynamics and any damage to barriers or asphalt. Clean-up may involve glass, plastics, and possible fluid spills, which require careful containment before traffic can resume. Officials say updates will appear on Main Roads channels as soon as conditions change.
Motorists should keep an eye on emergency alerts, live traffic maps, and radio bulletins throughout the day. If flexibility allows, work from home or stagger your commute until volumes ease. For those already on the road, patience, calm signaling, and courteous merging will help everyone move a little faster.
Even as frustration builds, responders are focused on safety and preventing further harm. “We understand the inconvenience, but the priority is safeguarding the people at the scene,” a police spokesperson said. With detours absorbing more cars by the minute, every cautious decision behind the wheel counts.
Ultimately, today’s gridlock is a reminder of how a single crash can ripple across an entire city. If you’re planning an afternoon return, keep plans fluid and check conditions before you set out. And if you must drive, stay present and give space—the quickest route home is a safe one.
