 A woman is in critical condition in hospital after the car she was in fell from a bridge and landed upside down in the middle of a busy motorway.

The horrific crash happened at the Bowburn interchange on the A1(M) in Durham at 10.35am yesterday.

A car driving on the A177 flyover left the carriageway and landed on its roof in the central reservation below.

The driver of the car freed themselves from the wreckage but the passenger, a woman in her mid-40s, had to be cut free and was then flown to hospital for treatment for 'serious injuries'.

Durham Police said a man in his early 30s was arrested at the scene on suspicion of causing serious injury by dangerous driving and remains in custody.

No other injuries have been reported, police said.

Detective constable Natalie Horner, of Durham Constabulary's Collision Investigation Unit, said: 'We would like to appeal for anyone who witnessed this incident, particularly anyone who has dashcam footage of the crash or the moments leading up to it, to get in touch with us as soon as possible.

'We would also urge anyone who saw this vehicle being driven between 9am and 10.30am today, especially in the Sherburn Village area, to contact us.'

The North East Ambulance Service said it requested help from the Great North Air Ambulance.

A spokeswoman said: 'Two patients were taken to hospital for further treatment; the first patient was taken by road to the University Hospital North Durham (UHND), and the second patient was flown to the Royal Victoria Infirmary Major Trauma Centre (RVI MTC).'

The A1(M) and the A177 were closed in both directions and are likely to stay closed until Saturday while repairs are carried out to safety barriers, according to police.

The site was close to the scene of a horrific fireball crash which killed three people in July and saw lorry driver Ion Onut, 41, from Galashiels, Scotland, jailed earlier this month for three counts of causing death by dangerous driving.
