Overturned Lorry Causes Major Fuel Spill and Extended Road Closure on A43 and M40 Junction 10

A heavy goods vehicle overturned on the A43 near M40 Junction 10 on June 16, 2026, causing a significant fuel spill that triggered major road closures and a large-scale emergency response. The incident halted traffic in both directions and forced the closure of the M40 northbound exit slip road at Junction 10 and the A43 link road at Cherwell Valley Services roundabout. Emergency services including police, fire crews, and National Highways recovery teams were rapidly deployed to secure the site, manage hazardous conditions, and prevent fire risks.

The crash created severe traffic disruption across the wider road network, with congestion building rapidly around Brackley and Cherwell Valley Services. Queues extended several miles onto surrounding approach roads and nearby local routes, forcing authorities to implement official diversion signs and direct drivers to alternative A-roads and bypass routes. Motorists were advised to check live traffic updates and avoid relying solely on navigation apps due to unpredictable congestion levels.

National Highways confirmed that recovery operations continued throughout the day to safely remove the overturned lorry and clear the fuel spill from the carriageway. The fuel leak spread across multiple lanes, creating hazardous driving conditions and forcing immediate closure while specialist cleanup teams worked at the scene. Authorities also initiated an investigation into the crash's cause, examining factors including speed, weather conditions, and possible mechanical failure.

According to National Highways, traffic was expected to gradually return to normal late in the evening of June 16, with reopening estimated between 22:45 and 23:00. However, officials stressed that this timeline depended on the successful completion of fuel spill clearance and safe vehicle recovery, and that any complications during recovery work could extend the closure further. Safety checks were required before reopening lanes to ensure the road surface was fully secure for public use. Commuters were urged to monitor live updates and contact National Highways Traffic Information at 0300 123 5000 for assistance.
