What drivers should do
National Highways advises motorists to allow extra time for overnight journeys. Signed diversion routes will direct traffic around closed sections, but delays are likely. Drivers travelling to or from airports, or making long-distance trips, should check traffic conditions before setting off, as reported by This Is Local London.
The works are weather-dependent and may change at short notice. No alternative arrangements, such as compensation for delays, have been announced. Residents planning overnight travel should monitor National Highways’ updates for real-time changes.
Why the closures are happening
National Highways has not specified the purpose of the works. Previous overnight closures on the M25 have included resurfacing, barrier repairs and emergency pothole filling. The agency typically schedules such works during low-traffic periods to minimise disruption.
Barnet Council has not issued any local advice regarding the closures. The council’s transport team confirmed it has not been consulted on diversion routes or alternative local arrangements. Residents seeking updates should refer to National Highways’ traffic alerts.
