M25 closed again! Motorway now shut until 6am Monday, so “only travel if necessary”
National Highways is predicting "long delays", with Senior Project Manager, Jonathan Wade saying: "Our advice is please only travel if absolutely necessary and make sure you give yourself extra time if you do choose to use the M25."
Big weekend events affected
While those travelling to Heathrow and Gatwick airports have been advised by the RAC to "leave earlier than usual", it's worth remembering that this particular closure coincides with the incredibly popular Goodwood Festival of Speed in Sussex, as well as the Wireless and British Summer Time festivals in London. With this in mind, the RAC is also encouraging drivers to "plan ahead" and take the train or tube if heading into the city.
Where is the M25 closure?
The M25[1] closure is between Junctions 10 and 11 to facilitate improvements to the A3/M25 intersection at Junction 10. Advertisement - Article continues below
The official diversion route for those heading clockwise between Junctions 10 and 11 is to turn off the M25 and head northbound on the A3 towards Painshill Junction. Turn off at the Cobham roundabout and head left onto the A245 towards Woking, and then right on the A320 to rejoin the M25 at Junction 11. Those travelling anticlockwise will do the same, but in reverse.
When is the next M25 closure?
The M25 was due to be closed during the daytime a total of five times throughout 2024 as part of a reworking of Junction 10, which happens to be the busiest section of Britain's busiest road, with over 300,000 vehicles passing through it every day on average.
The project, which is expected to be completed by Summer 2025 and will cost an eye-watering GBP317 million, involves a huge reworking of the J10 roundabout, including the installation of four new 'free-flow' lanes, as well as modifications and improvements of the surrounding roads and area.
