A stretch of the A17 just outside Lynn will be closed next week for overnight repairs, roads officials have announced.
Resurfacing work, which is expected to cost £120,000 to complete, is due to take place over three nights, subject to suitable weather conditions, beginning next Monday, July 13.
Norfolk County Council Highways officers say the A17 will be closed between the Pullover roundabout and the junction with Station Road, Clenchwarton, while the work is taking place.
The closure will be in place between 7pm and 6am each night.
Drivers travelling towards Lynn will be diverted off the A17 at Long Sutton and onto the A1101 before joining the A47 at Wisbech.
The westbound diversion will take motorists along the A47 before joining the A1101.
