Drivers are being warned there's a full weekend closure of on the Surrey-section of the M25 this weekend.
The motorway will be closed in both directions between Junction 10 at Wisley and 11 for Chertsey for a bridge demolition.
It will close at 9pm on Friday (7March) and won't reopen until 6AM on Monday (10 March).
National Highways say diversions will be in place but they are urging people to avoid the area.
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.”
What is happening on the M25 and why?
National Highways say 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.
