Man taken to hospital after M40 '˜welfare incident' near Banbury
The motorway was closed northbound between junctions ten (Middleton Stoney) and 11 (Banbury) at around 10.15am and the southbound slipway was also blocked.
Thames Valley Police said it was a ‘fear for welfare’ incident.
A man was taken to the John Radcliffe Hospital with serious injuries by road ambulance, a spokesman said.
The M40 was reopened at around 11am but the large closure caused delays to motorists.
Further down the M40 at J10, an overturned lorry has blocked a lane of the exit slipway northbound.
