Essential resurfacing work is to take place in Willington.
Work to resurface the A690 West Road between The Burn Inn mini roundabout and Helmington Row will begin on Saturday 5 March and will be carried out over three consecutive weekends.
The work from 7am to 7pm on Saturdays and Sundays will require temporary road closures, with a signposted diversion route in place.
On the first weekends, 5 and 6 and 12 and 13 March, the A690 will be closed between the B6299 North Lane and Helmington Row.
On 19 and 20 March, it will be closed between The Burn Inn mini-roundabout and Helmington Row.
The diversion route will take motorists between Crook and Willington via the A689 and B6286, through Howden-le-Wear and Hunwick.
Changes will be made to local bus routes while the work is carried out.
On the first two weekends, services will divert from Willington via the B6299 Watling Terrace, travel up North Lane then back into Crook past the golf course, picking up the usual route from High Jobs Hill.
On the third weekend, services will divert from Willington to Hunswick via the B6286, pass along Holy Well Lane, picking up the normal route from High Jobs Hill.
The work is being carried out on behalf of Durham County Council and forms part of its highway capital maintenance programme.
John Reed, the council’s head of technical services, said: “This work is part our essential resurfacing programme to maintain the highway network for everyone who uses the roads across the county. We would like to thank road users for their patience.”
