A crash involving a van and two cars on a key junction near Huntingdon is causing long delays.
Emergency services were called to the Brampton Hut interchange of the A1 and A14 at 7.28am after the three-vehicle crash. A traffic light has also been damaged.
An ambulance and paramedic officer treated a man in his 40s, who was later taken to Hinchingbrooke Hospital. He is not thought to have sustained any serious or life-threatening injuries.
Queues on the A14 eastbound are stretching as far back as Easton.
