Highways England project manager, Chris Corcoran, said:
This resurfacing work will improve the condition of the road surface for drivers using this major route through the region and we thank drivers for their patience.
The work is planned to be completed on the weekend of 24 to 27 July. The northbound carriageway will be closed from 8pm on the Friday 24 July to 6am on Monday 27 July. During this work there will be a contraflow in place on the southbound carriageway which will mean one lane will remain open to traffic in each direction through the weekend.
It is hoped the resurfacing work will be completed over this weekend, but if delays are experienced, i.e. due to bad weather, then the A1 will be returned to two lanes in each direction Monday to Friday and then the northbound closure reinstalled the following weekend (31 July to 3 August).
Following the completion of the work there will be separate closures of the southbound and northbound carriageway on consecutive nights to remove the traffic management.
During this work a speed limit of 50mph will be in place to allow motorists to run on the temporary road surface. A clearly signed diversion route will be in place via junction 59 (Aycliffe) and junction 61 (Bowburn interchange).
