In order to carry out the work lane closures will be in place on the A69 from the top of Warwick Bank to Corby Hill crossroads in Cumbia, known locally as Warwick Bridge, from 8.30am to 4.30pm each day when the work starts on 13 July.
A small amount of night time work will be necessary over the last two weeks of the work, 7 September to 18 September, between 6pm and 8am.
Highways England project manager Kyle Maylard said:
The new lights are more eco-friendly and will also improve light pollution for residents.
We are carrying out this work during the day to minimise the impact on residents although there will be some overnight work planned for the last two weeks of the scheme in September. The overnight work is away from residential properties and also on a narrow section of road and by carrying out the work overnight it will minimise the disruption for drivers.
