A major traffic incident has forced the complete closure of the A3 in Surrey, with the vital Hindhead Tunnel shut to all vehicles.
Police Respond to Serious Collision
Surrey Police are currently attending the scene of a collision on the A3. The force confirmed officers are en route and will be managing the incident. The exact nature and severity of the collision have not yet been disclosed by authorities.
Extent of the Road Closure
The closure is extensive, affecting the A3 in both directions. The blockage spans the section between the A3100 and the A333 junctions. Crucially, the Hindhead Tunnel is fully closed as part of this shutdown, severing a key route through the Surrey Hills.
Travel Chaos and Expected Delays
Motorists are being warned to expect significant disruption and long delays. With no through traffic possible on this major artery, drivers are urged to avoid the area entirely and seek alternative routes. The closure is likely to cause knock-on congestion on surrounding roads.
This remains a developing situation. The closure was announced on the evening of Thursday, 18 December 2025, with police arriving on scene shortly after.
