There will be overnight closures on Tuesday, 30 and Wednesday, 31 August on the eastbound side of the stretch of road between the Flying Horse roundabout (A511 and Copt Oak Road) at Markfield and junction 22 of the M1.
The closures will be in place from 8pm to 6am to allow the council to resurface a damaged stretch of road following an oil spill.
Motorists travelling in the opposite direction from Leicester to Coalville will be unaffected by the closures.
The diversion route for traffic travelling from Coalville towards the M1 and Leicester will be via the B591 Copt Oak Road, Whitwick Road and the eastbound slip road to the A50.
The work forms part of a scheme to improve the capacity of the A511 and cater for increased levels of traffic expected from a growing economy, particularly across north-west Leicestershire.
The scheme is partly funded by a £2.54 million contribution provided through the Leicester and Leicestershire Enterprise Partnership’s Local Growth Deal and managed by the county council.
