A two-car crash near to the A12 Hopton roundabout closed both Lowestoft-bound carriageways earlier this evening.
Police were called to reports of a collision at 4.29pm today, with the ambulance service also called.
An officer in the Norfolk police control room said a number of casualties suffered minor injuries.
Fire appliances from Great Yarmouth, Gorleston and Lowestoft attended and made the vehicles and scene safe.
It is understood the road has since re-opened.
