The A149 has now re-opened after a crash this morning which caused two-mile tailbacks.
The A149 in Dersingham was closed in both directions after the two-car crash, which has left three people in hospital.
Traffic was diverted via Manor Road and Sandringham after the collision, which happened between the George Pratt Roundabout and Wolferton turn-off.
Two fire crews from Sandringham were called at 4.55am to the crash south of the roundabout where the A149 meets the B1440. They used hydraulic rescue equipment to free the injured.
An ambulance service spokesman said one of the casualties suffered serious injuries, though the other two are not believed to be serious.
The crash happened on the same stretch of road as a collision in March 2013, in which Hunstanton-based PCSO Sandi Greenacre was killed.
