A serious road traffic collision has led to the complete closure of a key motorway in Hampshire, with emergency services including an air ambulance rushing to the scene.
Motorway Closed in Both Directions
The M27 motorway is currently shut in both directions between Southampton and Portsmouth following a major incident in the early hours of Tuesday, 6 January 2026. The closure affects the stretch between junctions 11 and 12.
National Highways has confirmed the closure and warned motorists that the road is expected to remain closed for a considerable period. All traffic is being diverted away from the area, causing significant disruption to the morning commute.
Emergency Response Underway
Hampshire's emergency services were alerted to the collision in the early hours. The severity of the incident prompted the dispatch of an air ambulance, which is now en route or has arrived at the location.
The exact nature of the collision and the number of vehicles involved have not yet been disclosed by authorities. However, the deployment of the air ambulance indicates that at least one person has sustained serious injuries requiring urgent medical attention.
Travel Disruption and Advice
Drivers are being urged to avoid the area entirely and to seek alternative routes for their journeys. Significant delays are expected on surrounding roads as traffic is rerouted.
National Highways is advising travellers to allow extra time for their journeys and to check for updates before setting out. The closure between J11 and J12 is impacting a vital artery connecting two major South Coast cities.
This remains a live incident, and further details will be provided by emergency services and traffic authorities as they become available.
