Serious Collision Forces M25 Closure Near Heathrow – Major Delays for Drivers
Motorists heading towards Heathrow faced chaos this morning after a serious crash forced a full closure of the M25 clockwise near Junction 14.
The collision happened in the early hours, just before 5am, shutting down all four lanes between the A3113 Airport Way and the stretch leading to Heathrow’s terminals.
Authorities at the scene confirmed that the motorway is unlikely to reopen before midday, sparking heavy congestion and long queues across west London.

Gridlock Around Heathrow
Traffic around Heathrow Airport quickly came to a standstill, with tailbacks stretching for miles. Drivers attempting to reach the terminals faced diversions via exit slip roads.
But delays are unavoidable; some motorists reported waiting in queues lasting up to an hour.
For travellers, the timing couldn’t be worse. Heathrow’s early morning rush coincided with the crash, leaving passengers stranded in traffic with fears of missed flights.
Warnings for Commuters
National Highways has urged drivers to avoid the area where possible. Alternative routes, however, are already under pressure as diverted vehicles flood local roads.
Local commuters expressed frustration at the situation. One driver posted online about the standstill, calling it “a nightmare for anyone heading to Heathrow this morning.”
When Will It Reopen?
Officials are working to clear the motorway, but recovery efforts and investigations are ongoing. The reopening is not expected before midday.
For now, the advice is clear: avoid the M25 near Heathrow if you can. Pack extra patience if you can’t.
The M25 traffic crisis near Heathrow this morning is another stark reminder of how fragile the UK’s busiest motorway can be after a single incident.
Travellers are urged to check live updates before setting off, with significant disruption likely to last through the afternoon.
