A woman escaped with minor injuries after her car crashed into a barrier on the A47 at Norwich.
Police were called to the scene just before 2pm on Thursday afternoon following the one-vehicle crash.
The East of England Ambulance Service were also in attendance as were Highways England due to an oil spill caused by the crash.
The driver was treated for minor injuries at the scene and was not taken to hospital.
One lane of the A47 was blocked eastbound between the Thickthorn roundabout and the A140 Ipswich Road junction for a couple of hours which caused long delays in the area.
