Major M65 crash: Seven-car smash shuts westbound carriageway and triggers hour-long delays
A multi-vehicle collision on the m65 has shut the westbound carriageway within Junction 3 at the Brimmicroft Interchange near Blackburn, producing hour-long delays and several miles of congestion. Emergency services remain at the scene as traffic is being rerouted off the motorway while authorities work to clear the carriageway and manage the growing tailback.
Why this matters now
The closure of the motorway at a busy interchange immediately creates a local transport bottleneck: National Highways North West confirmed the westbound carriageway within J3 is closed following a collision involving at least seven vehicles, with emergency services on site. That statement, combined with live traffic data noting six miles of congestion and delays of around 60 minutes, underscores the immediate disruption for commuters, freight and local services. The event compounds pressure on alternative routes as vehicles are forced onto junction slip roads and local roads.
M65 closure and immediate disruption
The collision is centred on J3 A674 Chorley Road (Blackburn West / Wheelton), and the closed section extends within the Brimmicroft Interchange. Motorists are being diverted using the exit and entry slip roads while emergency responders deal with the scene. One live traffic feed pointed to delays of 60 minutes and approximately six miles of congestion; another live traffic update registered delays extending up to 90 minutes, highlighting a widening span of disruption as queues grow toward J4.
Inconsistent early counts of vehicles involved have complicated response messaging: one authority cited at least seven vehicles in the collision, while Lancashire Constabulary confirmed officers were notified at 4: 20 p. m. ET and indicated six vehicles were involved. Those discrepancies do not change the operational reality on the ground: both notifications show all emergency services are attending and lanes remain closed westbound within J3. The m65 closure is already affecting traffic flows between J3 and J4, with congestion shown across adjacent slip roads.
What officials say and regional impact
National Highways North West issued a direct statement declaring the carriageway closed westbound within J3 at Brimmicroft Interchange near Blackburn and noting that all emergency services are on scene. Lancashire Constabulary confirmed its attendance and the initial notification time. Emergency services’ continued presence, along with traffic control measures, has led to significant delays for drivers and has forced local traffic authorities to adapt diversion plans in real time.
The immediate regional consequences include longer journey times for commuters, delayed deliveries for local businesses, and potential knock-on effects for timetabled services that rely on road access. Traffic management resources are concentrated at the interchange, and the rerouting onto slip roads is increasing volumes on nearby local roads, creating secondary congestion points. The m65 shutdown removes a key westbound artery at a junction that serves both through traffic and local access, intensifying the impact for the surrounding Blackburn area.
Operational updates from traffic monitoring services showed a growing backlog on the approaches, with some feeds noting a move from an initial 60-minute average delay toward longer waits. While emergency responders prioritise scene safety and casualty management, traffic authorities will stage systematic reopening only when the carriageway is safe and clear of debris. The m65 remains closed westbound at the time of the latest official statements, and motorists are being urged to avoid the area.
With lanes shut and diversions in place, authorities face the dual task of clearing the crash site and managing traffic displacement across local roads. How long the closure will last depends on on-scene recovery operations and any subsequent investigations; current indicators point to substantial disruption into the evening rush. The question now is whether contingency traffic plans and local road capacity will absorb the redirected flow without further gridlock—an operational test for regional traffic control and emergency coordination as responders work to reopen the carriageway and restore normal traffic patterns.
How will local authorities and traffic managers balance immediate clearance with longer-term traffic stability as the m65 incident unfolds?
