A significant disruption is expected on a stretch of the National Highways network in Hertfordshire, with a section of the strategic road network set to shut for several hours. The affected route, which will be closed from 21:00 on 13 August 2026 until 04:30 on 14 August 2026, is located near Watford, with the nearest city being the Hertfordshire town. The road in question is currently unidentified, with the specific location marked by National Highways Closure reference number 437384.

Motorists are being advised to plan their journeys carefully, with the highway authority urging drivers to check traffic apps and websites for the latest updates before embarking on their travels. A suggested alternative route for those intending to travel through the area has not been specified, but National Highways is expected to provide further information and guidance in the coming days. Those planning to use this section of the strategic road network are advised to leave plenty of time to reach their destinations, as the diversion is likely to cause significant delays.

The closure is part of ongoing works to improve the National Highways network, with the aim of reducing congestion and increasing safety for drivers. National Highways, the organisation responsible for the management and maintenance of the strategic road network, has promised to keep drivers informed about the latest developments. This includes providing regular updates on the status of the works, as well as any necessary advice or guidance for those affected by the disruption.
