Major Traffic Disruptions as M25 and M4 Motorways Shut Overnight
National Highways has issued warnings of significant traffic delays as two key motorways near London are closed for emergency works overnight. The closures are expected to impact local roads heavily, with disruptions likely to extend into the morning peak period.
M25 Closure Due to Fuel Leak and Resurfacing
The M25 is closed clockwise within Junction 25 at Waltham Cross in the early hours of Wednesday, February 18, 2026. This shutdown follows an incident where a lorry suffered a fuel leak, necessitating emergency resurfacing works. Contractors are currently on scene to complete these repairs. Traffic is being diverted via the exit and entry slip roads at this stage, but delays are anticipated as vehicles reroute through alternative paths.
M4 Shutdown for Structural Repairs Amid Wind Forecast
In Berkshire, the M4 is closed in both directions between Junction 10 at Wokingham and Junction 11 at Reading. This closure is due to structural damage discovered on a power line pylon near the motorway. Given forecasts of strong winds in the area, urgent repairs are required to prevent further issues. The M4 is expected to remain closed throughout the morning peak period, leading to long delays on local roads in the vicinity of the closure.
Ongoing Updates and Travel Advice
This is an ongoing event, and National Highways will provide further updates as the situation develops. Motorists are advised to plan alternative routes and allow extra travel time. The combined closures of these busy motorways are likely to cause widespread congestion, so staying informed via official channels is recommended for the latest traffic information.
