National Highways announces its final overnight closures of the northbound carriageway, between 8 pm and 6 am this week until Friday 2 August.
There will then be two remaining closures of the southbound carriageway, overnight between 8pm and 6am, on Monday 5 and Tuesday 6 August.
Closures will be between the A606 and A607 junctions, with a clearly signed diversion route in place via Melton Mowbray.
This will complete the work on this section of the A46.
National Highways said:
