Resurfacing work will be carried out at the roundabout junction of the A14 and the A43, near Kettering, later this month.
Due to the scale of the works and to protect the public and workforce, some road closures are needed on the roundabout over two weekends.
The first closure will be from 8pm on Friday, November 11, to 6am on Monday, November 14, with the second on the following weekend from 8pm on Friday, November 18, to 6am on Monday, November 21.
The roundabout closures will be phased with the west side of the roundabout closed on the first weekend (Broughton side).
The slip roads, both on and off the A14 on to the A43 towards Northampton will also be closed during this time.
The east side of the roundabout will be closed on the second weekend (Kettering side). The slip roads, both on and off the A14 on to the A43 towards Kettering will also be closed during this time.
A fully signed diversion route will be in place whilst the closures are on.
