M27 Motorway Shut in Both Directions After Police-Led Incident Triggers Three Miles of Queues and Major Delays

Motorists travelling along one of Hampshire’s busiest motorways faced major disruption after a police-led incident forced the closure of the M27 in both directions near Southampton. The sudden shutdown left drivers caught in lengthy queues, with congestion stretching for around three miles and delays reaching approximately 20 minutes as emergency services worked at the scene.

The incident occurred on Saturday, October 17, 2026, on the M27 between Junction 1, near the A31, and Junction 2 at Ower. Both the eastbound and westbound carriageways were closed, bringing traffic to a standstill along a key route used by commuters and travellers moving through the Southampton area. Drivers approaching the affected stretch were warned to expect disruption, while those already trapped in the queues faced uncertainty over how long they would have to wait.

Hampshire and Isle of Wight Constabulary confirmed that officers were attending an incident on the motorway and that closures had been put in place in both directions. Police urged motorists to avoid the affected section and seek alternative routes while officers remained at the scene. At the time of the report, authorities had not publicly disclosed the precise nature of the incident, and no further details about those involved were immediately available.

The closure created additional challenges for traffic management teams, who were required to deal with vehicles caught behind the roadblocks. Drivers at the back of the queues were reportedly being turned around to help clear the affected area. National Highways Traffic Officers also attended to assist police with managing traffic and directing motorists away from the closed carriageways.

As congestion built up, National Highways warned that further delays were possible. The reported three-mile queues and 20-minute delays on approach highlighted how quickly an incident on a major motorway can affect a large number of road users. Motorists heading towards Southampton or travelling through the surrounding area were advised to allow extra time for their journeys and consider alternative routes before setting off.

The M27 is an important transport link across Hampshire, connecting communities and providing access to Southampton, Portsmouth and other destinations along the south coast. When both carriageways are closed, the effects can extend beyond the immediate incident as traffic is diverted onto surrounding roads, potentially increasing pressure on local routes. Authorities did not provide a confirmed reopening time in the initial report, leaving drivers advised to monitor official traffic updates for the latest information.

Police remained at the scene as traffic officers worked to manage the disruption. The circumstances behind the incident had not been confirmed, and officials had yet to release further information. For motorists, the immediate priority was to avoid the closed section, follow diversion instructions and check for updates before travelling. Further details were expected as the situation developed.
