Drivers are being warned of massive delays as 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.
Daryl Jordan, of Woking Borough Council, said Byfleet Road, which is close to junction 10, had been “chock-a-block” on Friday afternoon.
“It is pulling people apart,” he added.
“When you work full-time and then you’re going to get home tonight from work thinking ‘I must fill the fridge up’ and you can’t even get into your own village. It’s going to be a nightmare.”
But, how long will the section 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?

The closure started at 9pm on Friday 15 March and the section will be shut until 6am on Monday 18 March, covering 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:
Junction 10 to junction 11: Northbound A3 to Painshill Junction, A245 towards Woking, and then A320 to M25 junction 11
Junction 11 to junction 10: A320 south towards Woking, A245 towards Byfleet and Painshill junction, Southbound A3 to junction 10.

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.
Wes Streeting has defended plans to make over 70s take compulsory eye tests every three years – which could see them banned from driving if they fail, it is understood.
Ministers are considering “tougher” measures to tackle road deaths and injuries in England and Wales, which they believe have “remained stubbornly high under successive Conservative governments”.
Under the new proposals, first reported by The Times, the drink-drive limit would be lowered to match the current rules in Scotland.
Currently, the drink-drive limit is 35 micrograms of alcohol per 100 millilitres of breath in England and Wales, or 80 milligrams of alcohol per 100 millilitres of blood.
But this is expected to be lowered to 22 micrograms of alcohol per 100 millilitres of breath or 50 milligrams of alcohol per 100 millilitres of blood, to match the stricter levels already enforced in Scotland.
Those caught not wearing a seatbelt could also receive penalty points for the first time, while drivers found on the road without insurance could also face more severe consequences.
As well as this, plans are currently being drawn up to make those aged 70 or over take a compulsory eye test every three years when they renew their driving licence.
Those who fail this would lose their right to drive under the proposals. It’s understood that tests for other conditions, such as dementia, are also being considered.
Speaking on Monday, Mr Streeting said the transport secretary is consulting and “considering a whole range of proposals”, which will be unveiled in the “not too distant future”.
It is understood that Heidi Alexander will unveil the measures in a new road safety strategy in the autumn.

The health secretary also defended the plans around elderly drivers.
He told broadcasters: “It cannot be right that we’ve ended up in a situation where the NHS is hit with a £2 billion a year bill because we are not taking road safety seriously enough – particularly as we get older and the quality of our eye health deteriorates, that we’re not keeping a regular check.”
A Labour source said: “At the end of the last Labour government, the number of people killed and seriously injured on our roads was at a record low, but numbers have remained stubbornly high under successive Conservative governments.
“In no other circumstance would we accept 1,600 people dying, with thousands more seriously injured, costing the NHS more than £2bn per year.
“This Labour government will deliver the first Road Safety Strategy in a decade, imposing tougher penalties on those breaking the law, protecting road users and restoring order to our roads.”
It comes after 1,633 people died in road traffic accidents in 2024, with nearly 28,000 victims seriously injured.
Image: The UK Health Security Agency (UKHSA) has issued alerts across England
The UKHSA, a government agency for England, warned “significant impacts are likely” across health and social care services due to the high temperatures.
Parts of the country are facing a fourth heatwave of the summer, where highs pass a threshold on three consecutive days.
A yellow alert, also between 9am on Tuesday until 6pm on Wednesday, covers the North East, North West, Yorkshire, The Humber, and the South West.
Dr Paul Coleman, consultant in public health at UKHSA, said temperatures are forecast to rise above 30C (86F) across some areas which “can result in serious health outcomes” particularly for the elderly or those with serious health conditions.
“If you have friends, family or neighbours who are vulnerable, it is important to ensure they are aware of the forecasts and are following the necessary advice.
“Check in on them if you can to make sure they know that hot weather is on the way and how to keep themselves safe,” Dr Coleman said.

Sky News meteorologist Christopher England said the high pressure that brought the warmth of the last few days via the “heat dome” effect is moving east, as low pressure moves in towards the west.
“On Tuesday, southern Britain can expect temperatures widely into the low 30s… perhaps exceeding 35C (95F) in places,” he said.

Drought in England explained
On 1 July, the UK recorded its hottest day of the year so far with a temperature of 34.7C (94.4F) recorded at St James’s Park in central London.
The Met Office’s criteria for a heatwave are met when temperatures are above a certain level for three consecutive days. This threshold varies from 25C to 28C (77F to 82F) depending on the location.

Mr England added: “There’s around a 10% chance Wales may exceed its August peak temperature of 35.2C (95.3F) recorded at Hawarden on 2 August 1990.
“Expect some tropical nights too, with temperatures holding above 20C (68F).”
The UKHSA has issued advice for keeping cool: • close windows and curtains in rooms that face the sun • seek shade and cover up outside • use sunscreen, wear a hat and sunglasses • keep out of the sun at the hottest times, between 11am and 3pm • restrict physical activity to the cooler mornings or evenings • know how to respond to heat exhaustion and heatstroke
Around 30 residents have been evacuated from their homes in north London after a water main burst, leaving roads under 44cm (17in) of water.
Seventy firefighters were dispatched by London Fire Brigade to the area around Canonbury Street in Islington just after 10pm on Sunday.
People have been urged to avoid the area including Essex Road, Elmore Street, Halliford Street and Ecclesbourne Road – and warned against driving through floodwater.

Fire crews used flood barriers and sandbags to divert floodwater away from homes as they warned disruption was likely to continue into Monday afternoon.
Islington council also warned at 9am on Monday that Canonbury Street was closed from Essex Road up to Arran Walk.
A Thames Water spokesperson said: “We have now managed to stop the flow of water and ensure that the site is safe. We have also been able to move parked cars which were over another critical water main.
“We have a specialist team on site for those impacted by the incident, at Cedar Place on Essex Road, and are supporting customers who have been affected.
“To keep the public and our team safe, we’ve arranged equipment to help manage the traffic while we work in the road. We are sorry for the impact this may have on traffic in the area.”
