Road Closure: M27 — Portsmouth

Motorists using the M27 are being warned of a planned closure at junction 12, leaving westbound, in the City of Portsmouth, from 10 February 2027 at 22:00 to 13 February 2027 at 05:00. The closure, which is due to major planned maintenance, will be managed by National Highways, the organisation responsible for the maintenance and operation of the UK's strategic road network. Drivers are advised to plan their journeys in advance and consider using alternative routes to avoid the disruption.

The M27 is a key route for traffic travelling to and from the port city of Portsmouth, and the closure is likely to cause significant delays, particularly during peak hours. National Highways has classified the disruption as medium severity, indicating that while the closure will have an impact on traffic flow, it is not expected to be catastrophic. However, drivers should still exercise caution and allow extra time for their journeys.

To minimise the impact of the closure, drivers are advised to check traffic apps and websites for the latest information on traffic conditions before setting out. This will enable them to plan their route and avoid the affected area if possible. Alternative routes, such as the A27 or A3, may be available, although these may also be busier than usual due to the diversion of traffic from the M27. Drivers should also consider leaving earlier than usual to account for any unexpected delays.

National Highways has planned the closure to take place overnight, when traffic volumes are lower, in an effort to minimise the disruption to motorists. However, the closure will still have an impact on early morning commuters and drivers who need to travel during the night. Drivers are advised to be patient and follow the diversion signs, which will be in place to guide them around the closure.

The M27 closure is just one of many planned maintenance projects being undertaken by National Highways to maintain and improve the UK's road network. While closures can be frustrating for drivers, they are an essential part of ensuring the safety and longevity of the roads.
