Police were called to deal with an unusual obstacle in the road.
Officers got the call to head to the A47 at Narborough, between Swaffham and King's Lynn, at 9.17am on Tuesday.
An obstacle had been reported, and on arrival officers found it was a car exhaust lying in the road.
Drivers were forced to swerve to avoid hitting the exhaust at the junction with Swaffham Road.
Police were able to remove the exhaust, and the road is now clear with no traffic build-up.
