UK Road Closed: National Highways Closure 516230

A section of the strategic road network in the South West of England is set to be closed this weekend, causing disruption to drivers heading in and out of Plymouth. The 516230 section of the National Highways network, which runs through the region, will be shut from 20:00 on Friday, 6th August 2026, until 03:00 on Saturday, 7th August 2026.

The exact road name has not been disclosed by the authorities, but motorists can expect significant delays and disruption during the 7-hour closure period. National Highways, the organisation responsible for the maintenance and upkeep of the UK's motorways and major A-roads, has confirmed the closure as part of its ongoing programme of works to improve the strategic road network. The closure is part of a series of planned works to upgrade and modernise the network, aiming to reduce congestion and improve journey times for drivers.

Motorists are being advised to plan their journeys in advance and check for alternative routes before setting out. The closure is expected to cause significant disruption to traffic flow, and drivers are urged to check traffic apps and websites for up-to-date information on traffic conditions. The M5 and A38 are likely to be the most affected routes, with drivers potentially facing long delays and congestion.

While the road closure is in place, drivers are being advised to allow extra time for their journeys and to consider using alternative routes, such as the A38 or the M5. Motorists are also being reminded to obey all road signs and to follow the instructions of traffic management staff on site. National Highways has assured that the closure is necessary to allow for essential maintenance and improvement works to be carried out safely and effectively.

The 516230 section of the National Highways network is a critical route for traffic heading in and out of Plymouth, and the closure is likely to cause significant disruption to local businesses and residents. However, National Highways has assured that the works are essential to improve the long-term resilience and sustainability of the network.

For the latest information on the road closure and the latest traffic updates, drivers are advised to check the National Highways website or to follow the organisation's social media accounts. Road Closures UK, the online platform providing real-time information on road closures across the country, will also be providing updates on the closure.
