Drivers planning to travel to Heathrow Airport this weekend should be aware of a significant overnight closure on the M25. National Highways has announced that the anticlockwise carriageway at junction 15, located between the M4 slip roads, will be shut from 8pm on Saturday, October 24, until 10am on Sunday, October 25. This closure will impact travellers heading to Heathrow Terminals 2 and 3.
Impact on Airport Access
M25 faces 31 overnight closures next week
Drivers should check National Highways for updates on planned maintenance works affecting junctions across London.
The closure at junction 15 means that the usual route for passengers travelling to Terminals 2 and 3 will be affected. Heathrow's published driving directions direct travellers for these terminals via the M4 and junction 15 area. However, access to Terminals 4 and 5 via M25 junction 14 will not be disrupted and will remain open.
Majid Ismailzada, marketing director at GM Rides, advised passengers to plan their journeys meticulously. He highlighted that the term 'overnight' might lead travellers to believe the work will be completed before morning journeys begin. However, he stressed that a lunchtime flight requires arrival at the airport by 9am, not including travel time, meaning journeys could fall much earlier than anticipated. He recommended working backwards from the required airport arrival time, accounting for check-in, security, and potential car park transfers.
Diversion Routes and Clock Change Confusion
M25 Closures Planned for October 2026
Motorists face overnight disruptions including a full closure of the QEII Bridge.
For drivers needing to continue anticlockwise past the closed section, the official diversion route involves taking the M4 westbound to junction 5. From there, travellers must then proceed eastbound to rejoin the M25 anticlockwise at junction 4b. Passengers are urged to check their specific terminal destination rather than entering 'Heathrow' as a general search, as routes can differ.
The timing of this closure is notable as it coincides with the end of British Summer Time. Clocks will go back one hour at 2am on Sunday, October 25. This change could potentially cause confusion for those arranging overnight collections or travel plans, particularly if their journey falls within the repeated hour. Mr Ismailzada advised confirming collection times directly with operators for any overnight bookings around this weekend.
Travellers are encouraged to check their airline's specific check-in and bag-drop deadlines and to consult Heathrow's official arrival guidance online. Drivers are also advised to follow the signed diversion routes and avoid making last-minute changes to their plans while driving.
