Motorists are advised of overnight road closures as Durham County Council carry out essential maintenance work starting next week.
The works, which will be completed in two phases, will be carried out on the A167 between Pity Me and Chester Moor.
On Tuesday 16 August, the northbound carriageway between Plawsworth and Chester Moor will be closed from 10.00pm until 6.00am. The southbound carriageway will then be closed on Wednesday 17 August, again between 10.00pm and 6.00am.
The second phase, which is from Pity Me to Plawsworth, will begin on Tuesday 23 August. The northbound carriageway will be closed from 10.00pm until 6.00am, with the southbound carriageway being closed on Wednesday 24 August, 10.00pm until 6.00am.
During the closures, traffic will be diverted via the A691 Durham to Lanchester – A6076 Lanchester to Stanley – A693 Stanley to Chester-le-Street A167 and vice versa.
Mark Readman, highways service manager, said: “The maintenance is essential to keep the highway safe for motorists. We’ll be carrying out the works overnight to make sure disruption is minimal but we’d like to thank everyone for their patience.”
