Delays are "likely" as a busy section of the A10 is set to close for resurfacing works later this month.
The closure will affect the A10 eastern bypass from its junction with the A10 Lynn Road roundabout for 68m southwards in Downham Market.
The road will be closed except for access between 7pm on May 30 and 6am on May 31.

A £1,000 maximum fine can be handed to drivers who ignore the road closures.
