A serious multi-vehicle collision has forced the complete closure of the M4 motorway, causing widespread traffic chaos and lengthy delays for thousands of travellers.
Emergency Response and Crash Details
Emergency services rushed to the scene between junctions 10 and 11 near Reading following reports of a significant multi-vehicle incident. Thames Valley Police confirmed they were dealing with a "serious collision" that required immediate closure of the motorway in both directions.
The crash occurred on Tuesday afternoon, with police, fire crews, and ambulance services all attending the scene. Witnesses reported seeing multiple emergency vehicles racing toward the affected area as authorities worked to manage the situation and assist those involved in the collision.
Travel Chaos and Diversion Routes
National Highways issued an urgent alert warning drivers to expect "severe delays" and avoid the area entirely if possible. The closure affected both carriageways between the key junctions, creating a major bottleneck on one of the country's busiest motorway routes.
Commuters and long-distance travellers faced massive disruption as traffic was forced onto diversion routes through surrounding areas. Local roads quickly became congested as drivers sought alternative paths around the closed section of motorway.
Traffic monitoring systems showed queues building rapidly in both directions, with some vehicles stuck for hours as emergency crews worked to clear the scene and investigate the circumstances surrounding the crash.
Ongoing Situation and Recovery
Recovery operations were expected to take several hours as authorities worked to remove damaged vehicles and ensure the safety of the carriageway before reopening. Specialist teams were brought in to assist with the clear-up operation.
Motorists were advised to allow extra time for their journeys and consider alternative routes until the situation was fully resolved. The closure came during a busy travel period, exacerbating the impact on road users and local communities.
As investigations continue into the cause of the multi-vehicle collision, authorities have emphasised the importance of road safety and urged drivers to check latest traffic updates before embarking on their journeys.
