A serious collision on the M25 in Surrey prompted a lengthy closure and travel warnings for airport-bound drivers, while the other supplied material did not address the disruption or offer a competing account.

The overnight crash turned a key stretch of the orbital motorway into a bottleneck just as morning traffic began building. Emergency crews needed time to investigate, leaving travellers to weigh diversions and longer journeys against an uncertain reopening timetable.

The M25 was closed in both directions between Junction 10 at Wisley and Junction 11 at Chertsey after the collision, reported shortly before midnight. Surrey Police, National Highways traffic officers and other emergency services attended the scene; the A245 Parvis Road was also shut in both directions.

The northbound carriageway towards Junction 11 later reopened, offering some relief, but queues continued to build as rush hour started. The closure’s most immediate consequence was for passengers travelling to Heathrow or Gatwick, whose usual M25 routes may be affected by congestion and diversions.

Authorities’ message was consistent: drivers should avoid the closed section where possible and allow more time. Surrey Police said journeys to either airport were “likely to be impacted,” while National Highways advised: “If this impacts on your planned route, please allow extra journey time.”¹

The available report did not specify the number of vehicles involved, injuries or a reopening time for the remaining closure. Its focus was instead on managing traffic while investigators completed their work, underscoring that the partial reopening had not removed the risk of significant delays.
