Overview
- A Surrey Police‑led response closed the M25 in Surrey after a serious collision that occurred at 11:55pm on Monday, with emergency services remaining on scene to investigate.
- Clockwise lanes were reopened early on Tuesday while the anti‑clockwise carriageway between J11 (Chertsey/Ottershaw) and J10 (Wisley/Cobham) remains shut.
- Traffic trapped inside the closure has been released using rearward relief and drivers are being diverted using the signed Hollow Square route and local roads.
- National Highways and Surrey Police warned the closure could last for several hours and urged drivers travelling to Heathrow or Gatwick to check journey times before departing.
- The M25 is London’s main orbital route so the J10–J11 shutdown is causing long knock‑on delays on the motorway and on nearby roads, and the scene is being cleared only after police finish their investigation.
