A MAJOR motorway is closed after a car flipped on its roof sparking huge delays for drivers.
The M40 in Oxfordshire is closed northbound between Junction 10 for Ardley, and Junction 11 for Banbury.
National Highways said the closure is due to a collision involving a vehicle which “left the road and came to rest on its roof”.
The agency said all emergency services including Thames Valley Police were on the scene.
Traffic ground to a halt earlier this afternoon following the crash with long delays building up on approach.
National Highways has warned motorists to plan ahead and allow for extra journey time.
Road users are urged to follow the diamond diversion symbol on road signs.
The diversion route advises exiting the M40 northbound at Junction 10 and joining the A43 northbound towards Brackley.
From there, drivers can turn left at the roundabout with the A422 near Brackley to join the A422 north-westerly, continuing onward to re-join the M40 at Junction 11.
