Drivers warned of huge hour-long delays after 'serious' collision on M40 in Warwickshire

National Highways have said that drivers may face delays of up to one hour on the M40 northbound between junction 12 (Gaydon) and junction 14 (Leamington Spa) in Warwickshire. All lanes are closed, with the road expected to remain closed “for an extended period of time”.

National Highways said in an update: “The M40 in Warwickshire is closed northbound between J12 (Gaydon) and J14 (Leamington Spa) due to a serious collision involving 2 vehicles.

“Emergency services including Warwickshire Police are in attendance. National Highways Traffic Officers are also on scene assisting with traffic management. The road is expected to remain closed for an extended period of time.”

Drivers are being advised to follow the ‘solid square’ diversion symbol for an alternative route. This will take drivers off of the M40 at J12 towards B4451 toward Gaydon, before re-joining the motorway at J14.

Warwickshire Police said in an update on X (formerly Twitter): “The #M40 is closed northbound between junction 12 for #Gaydon and junction 13 for #Warwick following a collision. It is likely to remain closed for some time including access from #WarwickServices. Please avoid the area.”
