Drivers reported delays in the area where a Christmas market took over the Norfolk Showground.
There were reports of delays averaging roughly 12 minutes on the A47 westbound between the B1108 Watton Road and Church Lane (Easton Roundabout).
Dereham Road was also affected by the traffic, with queues building from Longwater reaching back to where the road meets Marl Pit Lane and Larkman Lane in Earlham.
Long Lane, which takes drivers onto the Norfolk Showground, experienced similar traffic.
One lane of the A47 was closed due to drainage works being carried out by National Highways.
The Christmas Gift and Food show has been running at the Norfolk Showground since Friday.
