A woman died following a collision between two cars and two lorries on the A17, near the Pullover roundabout on Friday afternoon.
Emergency services were called to the scene of the crash, on the approach to the roundabout, at around 1.20pm after two HGVs and two cars were in collision.
The East Anglia Air Ambulance attended the scene, with two further ambulances and two fire engines from Lynn called to the crash.
A statement from Norfolk Police said: “Sadly the occupant of one of the cars died as a result of injuries sustained in the collision. Two other casualties, from one of the HGVs and one from the other car, were taken to hospital with minor injuries.”
The woman was thought to be in her 70s and a man of similar age was cut from one of the vehicles. He was airlifted to Lynn’s Queen Elizabeth Hospital where his condition was stabilised.
The road was closed for several hours while police carried out their investigations as to the cause of the crash, and while the vehicles were recovered.
Traffic was backed up from Main Road – the former main road from West Lynn to Clenchwarton – back to Sutton Bridge, with police diverting some motorists before Sutton Bridge to go through towards Wisbech through Tydd Gote.
Police are keen to hear from anyone who may have witnessed the collision and witnesses should contact the Serious Collision Investigation Team on 101.
The crash comes just two weeks after four people were injured, two of them seriously, in a crash on the A47 at Middleton.
That crash also took place on the bank holiday weekend, involving a car and a lorry which collided with each other before the car also crashed into a wall. Police have not revealed details of the condition of those injured.
