Emergency services were called to an incident on the Acle Straight following a crash which involved two vehicles.
Norfolk Police, fire and rescue and ambulance services attended the incident just after 12pm this afternoon.
The crash took place one mile from Great Yarmouth causing the Acle Straight heading towards Acle to be blocked off for over an hour.
This lead to long delays until police reopened the lane at 1.50pm.
Norfolk Fire and Rescue Service say crews used heavy rescue equipment to free one casualty and passed them into the care of the ambulance Service.
