Drivers reminded of M25 full weekend closure

The motorway will be closed from 9pm tonight (Friday 7 March) until 6am on Monday 10 March between junction 10 Wisley and junction 11 Chertsey.

This will allow contractors to safely demolish and remove an old bridge which is no longer needed after work to upgrade the gyratory at junction 10 was completed last month.

The closure has been planned months in advance to make sure it does not conflict with holiday periods or key events nearby, but drivers heading to London and the surrounding areas this weekend are being warned to expect delays and disruption.

Those travelling to Gatwick and Heathrow airports and the Channel ports may also be affected.

Jonathan Wade, National Highways Senior Project Manager, said: “We were grateful to drivers who listened to our advice during the three weekend closures last year and I’d again urge them to only use the motorway if their journey is absolutely necessary.

“Unfortunately, it’s simply not possible to carry out this scale of infrastructure improvement, which will benefit millions of people in the long term, without there being some degree of short-term disruption.

“We have spent months planning these closures, but they will still cause significant congestion and delays, so we are asking road users to allow extra time and use alternative routes where possible. Please follow our official diversion routes and not information from satnavs.”

Those travelling clockwise will be diverted onto the A3 northbound at junction 10 and then the A245 and A320 before rejoining the M25 at junction 11.

Those going in the opposite direction will take the A320 southbound at junction 11, before heading onto the A245 and the A3, rejoining the motorway at junction 10.

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 Garden Wisley, and will reduce the pollution caused by traffic jams.

Drivers are also being reminded of another full weekend closure between junctions 10 and 11 in two weeks’ time, from 9pm on Friday 21 March until 6am on Monday 24 March when another bridge will be demolished and removed.
