UK Road Closed: National Highways

A section of an important route in the National Highways Strategic Road Network will be closed overnight due to essential maintenance work. The unknown road, located near Slough, will be partially closed between 10 August 2026 at 21:00 and 11 August 2026 at 04:30, causing significant disruption to drivers in the area.

Motorists are advised to plan their journeys in advance and consider using alternative routes to avoid the closure, which is expected to cause high levels of congestion. The highway authority responsible for the maintenance work is National Highways, which has been working to improve the condition and safety of the strategic road network.

The closure is necessary to facilitate essential maintenance work, which is part of National Highways' ongoing efforts to maintain and improve the condition of the roads in the UK. Drivers can expect significant delays, particularly during the peak travel times, and are advised to check traffic apps and websites for up-to-date information on the road conditions and any other roadworks in the area.

National Highways has been working closely with traffic management teams to minimise the disruption caused by the closure, but drivers are still advised to expect delays and to plan their journeys accordingly. Motorists can use alternative routes, such as the A4 and the M25, which are expected to be less congested during the closure.

Drivers are also advised to check their journey planners and traffic apps, such as Waze, Google Maps, or the National Highways website, for up-to-date information on the road conditions and any other roadworks in the area. This will enable them to plan their journeys in advance and avoid any unnecessary delays.

The closure will take place over a relatively short period, but drivers are still advised to plan their journeys in advance and to allow plenty of time to reach their destinations. National Highways appreciates the patience and understanding of drivers during this time and is working to complete the maintenance work as quickly and safely as possible.
