While new streetlights are installed at junction 22, the southbound slip road onto the M1 from the A511 and A50 will be closed overnight for three nights.
The closure will be in place from 8pm to 6am on the evenings of 4th, 5th and 6th August for anyone wanting to access the motorway at junction 22 to head south towards junction 21 at Leicester.
Diversion routes will be signed, with motorists directed to use the A50 and A46 to continue their journey using the motorway at junction 21a.
The work forms part of a scheme to improve the capacity of the A511 to cater for increased levels of traffic expected from a growing economy, particularly across north-west Leicestershire.
The scheme should be completed by August this year.
Work already completed as part of the scheme includes resurfacing of the A511 to the Flying Horse roundabout and wider lanes around the junction 22 roundabout.
The project is partly funded by a £2.54 million contribution provided through the Leicester and Leicestershire Enterprise Partnership’s Local Growth Deal, and is being managed by Leicestershire County Council.
