M27 Road Closure — Portsmouth

Motorists are advised to plan their journeys in advance as a major closure is set to affect the M27 in the City of Portsmouth.

Motorists are advised to plan their journeys in advance as a major closure is set to affect the M27 in the City of Portsmouth. The eastbound carriageway of the M27 will be closed at Junction 12, near Portsmouth, from 20:00 on 4 June 2027 to 05:00 on 7 June 2027. National Highways, the organisation responsible for maintaining the country's major roads, has announced the closure, which is expected to cause medium-severity disruptions to traffic in the area.

The closure is due to major works being carried out by National Highways, although the exact nature of the works has not been disclosed. What is clear, however, is that drivers will need to find alternative routes to avoid the affected area. Those travelling eastbound on the M27 are advised to exit the motorway at Junction 11 and follow the diversion signs, which will direct them via the A27 and A3M to rejoin the M27 at Junction 13. This diversion is expected to add significant time to journeys, so drivers are advised to check traffic apps and plan their routes in advance to minimise delays.

Drivers can use traffic apps such as Waze or Google Maps to get the latest traffic updates and find the quickest routes to their destinations. It is also a good idea to check for updates on social media and traffic websites before setting off, as the situation may change. National Highways will be providing regular updates on the closure and any changes to the diversion route, so it's a good idea to follow them on social media to stay informed.

The City of Portsmouth is a busy area, and the closure of the M27 is likely to have a significant impact on traffic in the area. Drivers are advised to be patient and to allow plenty of time to reach their destinations. The closure is set to be in place for three nights, so drivers who regularly use the M27 should plan their journeys carefully to avoid the affected area.

National Highways has apologised for any inconvenience the closure may cause and is working to complete the works as quickly as possible. The organisation is responsible for maintaining the country's major roads and works hard to minimise disruptions to traffic. In this case, the closure is necessary to carry out major works, but National Highways is doing its best to keep drivers informed and to reduce the impact of the closure.
