UK Road Closed: National Highways

Motorists are advised to plan their journeys carefully as a significant section of the UK's motorway network will be closed overnight due to essential maintenance works. The affected area is on the M4, specifically junction 16 near Swindon, where traffic will be temporarily diverted from 12 August 2026 at 19:00 to 13 August 2026 at 05:00.

The closure is part of National Highways' ongoing efforts to ensure the reliability and safety of the Strategic Road Network. This essential maintenance will allow engineers to carry out vital repairs, thereby reducing the risk of future disruptions. The highway authority responsible for maintaining this stretch of the M4 is National Highways, which is working closely with its partners to provide the most efficient and effective traffic management possible.

Motorists are urged to exercise caution when approaching the affected area and to check for alternative routes before embarking on their journey. It is essential to note that traffic management plans are in place to mitigate the impact of the closure, but drivers are encouraged to plan ahead and check live traffic updates through reliable sources such as traffic apps and online resources. National Highways' Transport Data Feeds will provide up-to-the-minute information on traffic congestion and road conditions, helping drivers make informed decisions about their route.

While the closure is expected to cause minimal disruption during peak hours, commuters and long-distance drivers should be aware of the potential for delays and plan their journeys accordingly. It is crucial to allow extra time for travel and to consider alternative modes of transport if possible. National Highways has implemented a comprehensive traffic management plan, which includes lane closures and traffic diversions, to ensure that traffic flows as smoothly as possible during the closure period.

Motorists are also advised to follow the latest traffic updates and information on social media and online platforms, as these will provide the most up-to-date information on road conditions and any changes to the planned closure. By staying informed and planning ahead, drivers can help to reduce the impact of the closure and ensure a smoother journey.
