The second weekend closure of the M25 will take place between 10 and 13 May, National Highways has confirmed, with a seven-mile stretch of the road between junctions 9 and 10 in Surrey due to be shut.
In March a five-mile stretch of the motorway between junctions 10 and 11 was closed for a three-day period, the longest planned closure on the road since it was opened in 1986.
