England: closure of M25 - diversion routes

The M25 will be closed for a full weekend for the first time ever as a major project progresses to make journeys safer and reduce pollution. This will be the first of five closures between now and September 2024. Those travelling to Gatwick and Heathrow airports and Channel ports may be affected.

The Junction 10 improvement scheme will see an increase in the number of lanes to make journeys safer and improve traffic flow. It will also make it easier and safer to enter and exit the M25, provide safer entry roads for Wisley, Pyrford, Old Byfleet and RHS Wisley.

The local diversion route below will be in place which is the same for both directions:

Junction 10 - Junction 11: North bound A3 to Painshill Junction, A245 towards Woking, and then A320 to M25 Junction 11.

Junction 11 - Junction 10: A320 south towards Woking, A245 towards Byfleet and Painshill junction, Southbound A3 to Junction 10.

Taking the M25 in the other direction to avoid our closure is also an option.
The next full closure of the M25 is due to take place in April to allow for the installation of the new Clearmount bridleway bridge. Dates are subject to change.
