A major incident on the M25 has brought one of Britain's busiest motorways to a standstill during the Friday morning rush hour. Emergency services are currently on the scene of a serious multi-vehicle collision that has forced the complete closure of the clockwise carriageway.
Severe Disruption Near Heathrow
The incident occurred between junction 10 for the A3 and junction 11 for Chertsey, causing immediate gridlock in the critical Heathrow Airport approach area. National Highways has confirmed the closure is expected to remain in place for several hours as collision investigation work gets underway.
Drivers are facing miles of stationary traffic with queues rapidly building back towards junction 8 at Reigate. The anticlockwise carriageway, while remaining open, is experiencing significant slowdowns due to rubbernecking.
Emergency Response and Diversions
Surrey Police, along with multiple ambulance crews and fire engines, responded to the incident just after 6:30 AM. A complex recovery operation is now in progress.
National Highways has implemented the following official diversion route:
- Exit the M25 at junction 10 and take the A3 northbound
- Continue to the A245 and head towards Byfleet
- Join the A317 south to the M25 junction 11
Motorists are being strongly advised to avoid the area entirely if possible. Considerable delays are expected to persist throughout the morning, with a significant impact on journeys to Heathrow Airport and surrounding areas.
Travel Advice for Affected Passengers
Heathrow Airport has warned passengers to allow substantial extra time for their journeys. The airport chaos comes on what is typically one of the busiest travel days of the week.
Public transport alternatives, including Heathrow Express and TfL Rail services from Paddington, are expected to be exceptionally busy. Local roads in Surrey, including those through Addlestone, Weybridge, and Byfleet, are already experiencing severe congestion as traffic seeks alternative routes.
This developing story represents one of the most significant disruptions to the M25 in recent months. Drivers should monitor live traffic updates and expect lengthy delays even after the motorway reopens.
