Drivers are being warned of massive delays when the M25 shuts in both directions this weekend in an unprecedented move.
The closure between junctions 10 and 11 in Surrey on the UK’s busiest motorway could cause chaos.
When exactly is it going to be shut, where are the diversion routes and why is it happening? Here’s everything you need to know.
When is the closure and how long will it last?
It’s from 9pm on Friday 15 March to 6am on Monday 18 March and covers the five-mile stretch between junction 10 and 11.
What is the diversion route?
Here’s the diversion route that’s been outlined by National Highways, which maintains England’s motorways:

Satnav warnings
Drivers are being urged to ignore satnavs and only follow official diversion routes to prevent causing gridlock during an “unprecedented” closure.
Jonathan Wade, National Highways project lead, said the amount of disruption will partly depend on whether drivers stick to official diversions.
“How many people are going to take the initiative and try and use satnavs?”, he told PA news agency.
“There’s probably a greater risk of congestion by people just doing their own thing and thinking they can perhaps beat the signs and find a shorter or quicker route.
“That will cause further congestion on some of the key junctions so please avoid doing that if at all possible.”
National Highways senior project manager Daniel Kittredge said: “If people move away from diversion routes that we prescribe, it creates additional issues in different parts of the road network.
“The majority of the time that will be local roads, so that really impacts residents in those particular areas.
“That’s why we’re trying to encourage people to not follow the satnav.
“Stick on the prescribed diversion route. It’s going to be more suitable for your journey.”
How bad could it be?
It’s the first scheduled daytime all-lanes shutdown on the M25 since it opened, so it’s not yet known exactly how bad delays are going to be.
This section of the M25 normally carries between 4,000 and 6,000 vehicles in each direction per hour from 10am until 9pm at weekends, so the disruption caused by the works is expected to be significant.
More than 200,000 vehicles are expected to be affected, including many travelling in and out of London, and to and from Heathrow and Gatwick airports and Channel ports.
What advice has been issued?
“Drivers should only use the M25 if their journey is absolutely necessary,” says Jonathan Wade, National Highways project lead.
“This is the first of five full closures of one of the busiest junctions on our road network,” he adds.
“We have spent months planning for these closures and making sure there are diversion routes in place, but there will still be heavy congestion and delays.”
‘Motorists should decorate the bathroom’
The government-owned company’s chief also advises motorists to find something to do at home like “decorate the bathroom” or “play in the garden” ahead of the closure.
Mr Wade says how well the area copes with the closure will partly depend on whether drivers stick to official diversions – but urges people to avoid travelling altogether.
“Avoid the area totally if you can,” he told The Independent’s daily travel podcast.
“Either avoid travelling completely or find something to do at home, decorate the bathroom or something, I don’t know, or play in the garden.
“If you must go, travel by train, walk, use your bicycle.
“If you can, avoid driving anywhere around those diversionary routes.”
Airport warnings
People due to travel to Gatwick and Heathrow could also be affected by the closure.
Heathrow Airport is advising passengers planning to use this part of the M25 to allow for extra time before their flight.
“Passengers using public transport should also be aware that The Airline (between Heathrow and Gatwick) and RailAir (RA2), will be running amended timetables over this weekend, please check with your operator for the latest information,” their statement adds.
A London Gatwick Airport spokesperson told Sky News: “Passengers driving to the airport are advised to check diversion routes before they travel and allow extra time for potential delays.
“Gatwick’s train station is well connected and is a great alternative option for people travelling to the airport this weekend.”
‘You ain’t seen nothing yet’
Steve Gooding, director of motoring research charity the RAC Foundation, says: “For drivers who’ve already had their patience tried by the queues at the junction 10 works, the phrase ‘you ain’t seen nothing yet’ springs to mind.”
“National Highways’ plea for people to avoid driving in the area applies not just to trips on the M25, but also to those on surrounding local roads onto which the M25 traffic will be diverted,” he adds.
“The hope must be that drivers take great care, however frustrating the delays and disruption might be.
“The last thing we need is shunts or crashes, however minor, because the slightest mishap will compound the misery.”
Government-owned company National Highways said the action is necessary to enable a bridge to be demolished and a new gantry to be installed as part of a £317m improvement project.
National Highways says the project will increase the number of lanes and make it easier to enter and exit the M25 at junction 10, which is one of the UK’s busiest and most dangerous motorway junctions.
“These improvements will bring long-term benefits to drivers who pass through this stretch of the M25, not to mention pedestrians, cyclists and horse riders who will also see positive changes in the area,” says its project lead Jonathan Wade.
Is the closure a one-off?
No – it’s just one of five planned full closures between the junctions. The other dates have not yet been confirmed.
“Three of those closures will be between junctions 10 and 11 – the A320 at Chertsey… and two of them will be between junction 9 at Leatherhead to junction 10 at Wisley,” Mr Wade said.
He said the dates of the later stages would be released in due course with motorists given plenty of notice.
“We will not just spring them on people,” he said, adding they would take place between May and December.
The project began in summer 2022 and is expected to last three years in total.
A 92-year-old man has been sentenced to life with a minimum term of 20 years in prison for the rape and murder of an elderly widow nearly 60 years ago.
Ryland Headley was found guilty on Monday of killing 75-year-old Louisa Dunne at her Bristol home in June 1967, in what is thought to be the UK’s longest cold case to reach trial, and has been told by the judge he “will die in prison”.
The mother-of-two’s body was found by neighbours after Headley, then a 34-year-old railway worker, forced his way inside the terraced house in the Easton area before attacking her.

The UK’s longest cold case to reach trial
Police found traces of semen and a palm print on one of the rear windows inside the house – but it was about 20 years before DNA testing.
The case remained unsolved for more than 50 years until Avon and Somerset detectives sent off items from the original investigation and found a DNA match to Headley.
He had moved to Suffolk after the murder and served a prison sentence for raping two elderly women in 1977.
Prosecutors said the convictions showed he had a “tendency” to break into people’s homes at night and, in some cases, “target an elderly woman living alone, to have sex with her despite her attempts to fend him off, and to threaten violence”.

Headley, from Ipswich, who did not give evidence, denied raping and murdering Ms Dunne, but was found guilty of both charges after a trial at Bristol Crown Court.
Detectives said forces across the country are investigating whether Headley could be linked to other unsolved crimes.
Mrs Dunne’s granddaughter, Mary Dainton, who was 20 when her relative was killed, told the court that her murder “had a big impact on my mother, my aunt and her family.
“I don’t think my mother ever recovered from it. The anxiety caused by her mother’s brutal rape and murder clouded the rest of her life.
“The fact the offender wasn’t caught caused my mother to become and remain very ill.
“When people found out about the murder, they withdrew from us. In my experience, there is a stigma attached to rape and murder.”

Finding out her grandmother’s killer had been caught after almost six decades “turned my life upside down,” she said.
“I feel sad and very tired, which has affected the relationships I have with those close to me. I didn’t expect to deal with something of such emotional significance at this stage of my life.
“It saddens me deeply that all the people who knew and loved Louisa are not here to see that justice has been done.”

After her statement, Mr Justice Sweeting told Mrs Dainton: “It is not easy to talk about matters like this in public.
“Thank you very much for doing it in such a clear and dignified way.”
The judge told Headley his crimes showed “a complete disregard for human life and dignity.
“Mrs Dunne was vulnerable, she was a small elderly woman living alone. You treated her as a means to an end.
“The violation of her home, her body and ultimately her life was a pitiless and cruel act by a depraved man.
“She must have experienced considerable pain and fear before her death,” he said.
Sentencing Headley to life imprisonment with a minimum term of 20 years, the judge told him: “You will never be released, you will die in prison.”
Detective Inspector Dave Marchant of Avon and Somerset Police said Headley was “finally facing justice for the horrific crimes he committed against Louisa in 1967.
“The impact of this crime has cast a long shadow over the city and in particular Louisa’s family, who have had to deal with the sadness and trauma ever since.”
The officer praised Ms Dainton’s “resilience and courage” during what he called a “unique” case and thanked investigators from his own force, as well as South West Forensics, detectives from Suffolk Constabulary, the National Crime Agency and the Crown Prosecution Service (CPS).
Three managers at the hospital where Lucy Letby worked have been arrested on suspicion of gross negligence manslaughter.
They were in senior roles at the Countess of Chester Hospital in 2015 and 2016 and have been bailed pending further enquiries, Cheshire Constabulary said. Their names have not been made public.
Letby, 35, was found guilty of murdering seven children and attempting to murder seven more between June 2015 and June 2016 while working in the hospital’s neonatal unit.
Detective Superintendent Paul Hughes explained that gross negligent manslaughter focuses on the “action or inaction of individuals”.
There is also an investigation into corporate manslaughter at the hospital, which began in October 2023.
That focuses on “senior leadership and their decision-making”, Mr Hughes said. The intention there is to determine whether any “criminality has taken place concerning the response to the increased levels of fatalities”.
The scope was widened to include gross negligence manslaughter in March of this year.

Mr Hughes said it is “important to note” that this latest development “does not impact on the convictions of Lucy Letby for multiple offences of murder and attempted murder”.
He added: “Both the corporate manslaughter and gross negligence manslaughter elements of the investigation are continuing and there are no set timescales for these.
“Our investigation into the deaths and non-fatal collapses of babies at the neo-natal units of both the Countess of Chester Hospital and the Liverpool Women’s Hospital between the period of 2012 to 2016 is also ongoing.”
Earlier this year, lawyers for Lucy Letby called for the suspension of the inquiry, claiming there was “overwhelming and compelling evidence” that her convictions were unsafe.
Their evidence has been passed to the Criminal Cases Review Commission (CCRC), which investigates potential miscarriages of justice, and Letby’s legal team hopes her case will be referred back to the Court of Appeal.
As we pulled back the hospital curtain, he was hunched over and clearly in pain.
He had climbed off the hospital bed to greet us with a polite smile, then hobbled back to lie down again.
Every breath was uncomfortable, but he wanted to share the horrible reality of knife crime.

“I’ve never in my life been stabbed so I don’t know how it’s meant to even feel,” he said.
“The pain came when I realised the blood’s just spitting out of the side of my rib cage and that’s when I started panicking.
“My lungs felt like they were filled with blood… I thought each breath that I take, I’m going to drown in my own blood.
“I just felt as though I was slowly slipping away.”
Paramedics helped save his life and got him to the hospital in Manchester.
Sky News cannot name the young victim or go into the details of the attack because the police are investigating his case.
We were alongside a support worker called Favour, who is part of a growing team called Navigators. They go into hospitals to help young victims of violence.
While checking on how his recovery is going, she gently asked what he wanted to do next.
“You should have the right to feel safe,” she said to him.
“So don’t blame yourself for what happened… we are going to be there to help you.”

‘Scarring and traumatic’
In a corridor outside the major trauma ward at the Manchester Royal Infirmary, Favour said: “They are often scared, often really tired from being in hospital.
“It does stay with you, not just for a couple of weeks, but it can go on for months, years, because it is something very scarring and traumatic.
“Having someone to talk to, being able to be very vulnerable with… that can lead you to find different spaces that are safe for you, can make a huge difference.”
In the adjacent Children’s Hospital in Manchester, we met the clinical lead at the Greater Manchester Violence Reduction Unit.

Dr Rachel Jenner is a senior consultant who expanded her emergency department work into the wider mission of violence reduction after treating one particular young stab victim.
“When he arrived at the hospital, he was obviously very distressed and stressed,” she said. “A little bit later on, when things were stable, I asked him if he wanted me to call his mum.
“When I asked that question, he just kind of physically crumpled on the bed and just looked like the vulnerable child that he was, and that was really impactful for me.”

‘Positive results’
The Violence Reduction Unit was established in 2019 with a commitment from the city’s authorities to work together better to prevent violence and deal with it efficiently when it occurs.
Dr Jenner still treats young knife crime victims, but revealed the number of stab-related admissions is falling in her hospital.
“The trend is downwards,” she confirmed. “We’ve definitely seen some positive results.”
The latest statistics in England and Wales show the number of hospital admissions for assault by a sharp object fell by 3% to 3,735 admissions in the year ending September 2024.
“We’re never complacent,” Dr Jenner said. “You reality check yourself all the time, because obviously if… someone gets stabbed, then it’s quite possible that I’ll be treating them.”
She said the Navigators are crucial to working with young patients.
“They have a really different way of engaging with young people, they’re much better at it than many other professionals,” she said.
“It’s not a one-size-fits-all model, they actually wrap around that support according to circumstances… that’s a really positive improvement.”
Tacking violence ‘like infectious disease’
Dr Jenner added: “We try and take a public health approach to violence reduction. In the same way that we would address an infectious disease, if we can use those methods and principles to look at violence.
“Not just reacting when it happens, but actually looking at how we can prevent the disease of violence, that in the long term will have a bigger impact.”
The key is teamwork, Dr Jenner said. Collaboration between the police, community leaders, victim support, health workers and people in education has noticeably improved.
The hospital also sends consultants into schools to teach pupils how to stop bleeds as part of an annual nationwide initiative that reaches 50,000 young people.
At a Stop The Bleed session in Bolton, Greater Manchester, we met 11 and 12-year-olds growing up with the threat of knife crime.
One Year 7 boy said: “There was a stabbing quite near where I live so it does happen, but it’s very crucial to learn how to stop this bleed and how to stop deaths.”
Another two friends talked about a boy their age who had been involved in an incident with a knife.
“No one would expect it for someone that young,” one said. “They’re just new to high school, fresh out of primary, and they shouldn’t just be doing that, too young.”

‘We are dealing with it every day’
Their school has decided to tackle the problem of knife crime head-on rather than pretend it isn’t affecting their pupils.
The pastoral lead at the school, Sanaa Karajada, told Sky News: “We are dealing with it every single day, so we have policies and procedures in place to prevent any escalations in our schools or in the community.
“It is very, very worrying and it’s upsetting that [students] are having to go through this, but you know we’ve got to be realistic… if we are shying away from it, we’re just saying it’s not a problem.
“But it is a problem within the community, it’s a problem in all of the UK.”
The government has pledged to halve knife crime within a decade.
These signs of progress may offer some hope, but there is still so much work to do.
