A 39-year-old woman was treated for cuts after climbing from her overturned car following an accident at Sutton Bridge.
The A17 was closed for a number of hours last night following a collision between four vehicles and a 30-seater bus.
Emergency services were called to the scene about 8.40pm to find a Daewoo Matiz, driven by the Sutton Bridge woman, a Ford Fiesta, a Mercedes B180, a Volkswagen Beetle. The bus was empty.
The driver of the Fiesta, a man from Norfolk (age not confirmed) was taken to hospital in Kings Lynn with serious leg fractures.
