The M25 in Hertfordshire heading towards Heathrow Airport has been closed on Wednesday (April 30) anti-clockwise between J17 (Rickmansworth) and J16 (M40) due to a crash which reportedly involved three lorries.
Emergency services are on the scene with traffic being diverted. There are reports of congestion tailing back as far as J19 (Watford) and for two miles down the A412 to Denham.
Online traffic site Inrix reports ‘severe delays’ on the M25 with National Highways warning drivers it is taking 70 minutes above normal travel time to get through the area.
