Motorists are advised that an essential maintenance project is set to cause significant disruption to traffic on the M25 near Watford, affecting commuters and long-distance drivers alike. The closure will take place on the M25, specifically at National Highways Closure — 507320, from 22:00 on 14 August 2026 to 05:00 on 15 August 2026.

This essential maintenance project, undertaken by National Highways, forms part of their Strategic Road Network upgrade. Work will see overnight resurfacing and improvements, which necessitate a lane closure on the M25. The precise location of the works is National Highways Closure — 507320.

Motorists using the M25 are advised to plan their journeys in advance to avoid the disruption. The best course of action is to check for alternative routes before embarking on your journey. Utilising traffic apps such as Waze or Google Maps can also provide real-time information about traffic conditions. Furthermore, drivers may consider leaving earlier to allow for extra travel time to reach their destination safely.

In preparation for the works, drivers should be aware of the scheduled lane closures and take necessary precautions. The overnight closure is set to cause significant disruption, and commuters may experience delays. Motorists are urged to exercise patience and caution during this time.

National Highways, the authority responsible for maintaining the Strategic Road Network, has announced the works in advance to allow for adequate notice. Motorists are advised to stay up-to-date with the latest information regarding the works, including any last-minute changes to the schedule.

While the overnight closure may cause inconvenience to drivers, the eventual upgrade to the Strategic Road Network is expected to enhance road safety and reduce congestion. The maintenance project is part of a broader effort to improve the UK's transportation infrastructure.
