A serious collision has caused severe disruption on the M25 motorway this morning, leading to significant delays for travellers heading to Heathrow Airport.
Crash Closes Key Heathrow Exit
The incident, which occurred in the clockwise carriageway, has forced the closure of the exit slip road at junction 14. This junction provides direct access to Heathrow's Terminals 4 and 5. National Highways crews are currently at the scene working to clear the vehicles involved in the crash.
Diversions and Growing Queues
With the slip road shut, heavy queues are building on the approach to the affected junction. Drivers aiming for Heathrow are being instructed to continue past the closed exit. The official diversion route advises motorists to travel on to junction 15 and then join the M4 motorway to double back towards the airport.
This closure comes on 23 December 2025, a traditionally busy period for airport traffic, exacerbating the impact on holiday travellers. Authorities have urged all drivers to allow extra time for their journeys and to check live traffic updates before setting out.
Ongoing Response and Travel Advice
The emergency response and recovery operation is ongoing. While there is no estimated time for the slip road to reopen, the presence of National Highways suggests efforts are underway to resolve the situation as swiftly as possible.
The key advice for motorists remains to plan ahead and consider alternative routes if travelling towards Heathrow Airport this morning. The disruption is expected to affect both airport traffic and general commuter flow on this critical section of the London orbital motorway.
