Overview
- A car hit the central reservation on the M5 early on Monday, June 29, leaving a woman seriously injured and forcing the southbound carriageway to close before it was reopened with about two miles of congestion and roughly 20 minutes delay.
- A separate serious collision on the M1 in Leicestershire on Sunday, June 28 closed the northbound carriageway between junctions 20 and 21, prompted an air ambulance response, and saw one person rescued from a vehicle and taken to hospital.
- National Highways has scheduled emergency resurfacing on the M1 southbound between junctions 5 and 1 after crews found an infrastructure defect, with the carriageway closed overnight and lane restrictions in place while repairs continue.
- Other incidents over the weekend and into Monday — including a major lorry fire on the M6, a vehicle breakdown on the M61, crashes on the M55 and recurring M25 lane restrictions — combined with planned engineering work to produce wide knock‑on delays and diversion routing.
- Motorists are being urged to plan journeys, follow signed diversions and live traffic updates, and expect extended journey times while police, fire services and National Highways complete forensic work, vehicle recovery and resurfacing.
