The A11 has re-opened following a crash which closed the Norwich-bound carriageway at Attleborough for almost four hours.
Emergency services were called to the road at just before 7.45pm tonight.
Norfolk police said a member of the public called to say two lorries and a car had been involved in a crash.
Highways England tweeted that an overturned HGV was blocking the road at the B1077 junction.
They said traffic heading towards Norwich was being diverted via the exit and entry slip roads to get around the vehicle.
Police, firefighters from Attleborough, Wymondham and Carrow and ambulance crews have gone to the scene, but a police spokeswoman said it did not appear that anybody was badly hurt.
The carriageway re-opened just before 11.30pm.
