Police have warned that one of the main routes out of Lynn will have to be closed for several hours this evening in order to recover a lorry that has overturned at a busy junction.
Emergency crews were called to the Pullover roundabout, where the A47 meets the A17, shortly after 3pm this afternoon following the incident.
In posts on their Twitter account, Lynn police say traffic is currently able to pass the scene in single file.
However, they said the road would have to be closed to move the lorry back to an upright position and clear its cargo from the road.
It is estimated that could take between seven and eight hours.
There are already reports of long queues in the area, but no details of any injuries.
The incident is the second on the A47 around Lynn today after fire crews were called to a vehicle blaze near the Hardwick roundabout shortly before noon.
