Two air ambulance helicopters landed on the A14 on Saturday afternoon to airlift two people injured in a road smash.
The accident happened at about 3.30pm on the westbound carriageway of the A14 near junction 10 when a red Golf vehicle overturned and became wedged between the crash barrier and side wall of the carriageway.
Fire crews from Northamptonshire had to cut one person from the vehicle.
The Derbyshire, Leicestershire and Rutland Air Ambulance landed on the carriageway – which had been closed by officers – at about 3.57pm.
A spokesman for the air ambulance said: “They tended to a 55-year-old man, who was in the passenger seat.
“He was treated for a suspected internal haemorrhage at the scene, before being airlifted to University Hospitals Coventry and Warwickshire for further treatment.
“Warwickshire and Northamptonshire Air Ambulance were tasked to the same incident at the request of the first air ambulance, landing at the scene at 4.22pm.
“They tended to the driver of the vehicle, a 55-year-old woman, who had sustained head injuries.
“She had already been immobilised by crews from East Midlands Ambulance Service.”
A spokesman for Northamptonshire Police said the A14 was closed while the incident was dealt with.
