A man has died following a crash on the A1 on Friday morning.
The 44-year-old man was airlifted to hospital with life-theatening injuries following the collision.
A spokeswoman for Northumbria Police said today that the man died some time between Friday evening and Saturday morning. He has not been named.
Both carriageways of the A1 were closed between the B6347 South Charlton junction and the A1068 Alnwick junction for six hours following the collision between a car and a van. Emergency services were called to the scene at 8.25am.
The seriously injured man was given blood at the scene and flown to the RVI in Newcastle by the Great North Air Ambulance. Another man was taken to Wansbeck General Hospital with less serious injuries.
