On Thursday, miles of traffic backed up on the M25 due to a lorry that caught fire near the Wisley Interchange. The M25 anticlockwise is closed, with a seven-mile tailback between Junctions 10 A3 and J8 A217. There is also congestion in several Surrey towns as drivers follow an official diversion route as well as their own detours to avoid the traffic. The road was closed in both directions shortly after 4 a.m., and J10 was closed around 5:10 a.m., but it reopened clockwise at 6 a.m. Traffic is diverted via the A3 to Tolworth, then the A240 to Burgh Heath, and finally the A217 back to the M25 at Reigate.
