Work will take place between 8pm and 6am to carry out carriageway repairs on the Easton roundabout.
To allow traffic to be diverted on suitable roads during the work, the A47 will be closed between Swaffham and Longwater. A diversion will be clearly signposted via the A11, A134 and A1065 for westbound traffic, and via the A1065, A148, A1067 and A1074 for eastbound traffic. Access to local properties will be maintained at all times.
Highways England project manager Andrew Dyer said:
Carrying out this work now will ensure smoother journeys for road users along the A47 in Norfolk.
We have worked closely with Norfolk County Council to agree diversions and have planned this work at night to minimise disruption to road users.
Motorists affected by this work are advised to plan ahead and allow extra time for travel.
