The work, which will take place between junctions 15 and 17, will involve removing the old overhead message signs and replacing them with new models.
Highways England project manager Neil Doherty said:
This work will ensure better journeys for drivers as they will benefit from the latest technology to get up-to-date information about hazards or delays ahead.
We have timed the work to be minimise disruption but we are advising people to allow extra time for their journeys when closures are in place.
The first phase of work will be carried out in the roadside verges using hard shoulder closures only and should be completed on 22 January 2016. Road users will not be affected during this phase and no work will be carried out over the Christmas period.
The second phase, which will start on 25 January, will require overnight lane and slip roads closures, which will be clearly signposted in advance. During the slip road closures, there will be a clearly signed diversion diverting traffic via the next A1(M) junction.
There will be a third phase of work between end February and March to switch the signs on, which will also require lane and slip road closures.
The work is planned for completion in spring 2016, weather permitting.
