Motorists have been warned to plan alternative routes ahead of another closure of the Stanion roundabout.
The roundabout, which connects the A43 and the A6116, was also shut in September, bringing chaos to the roads.
A second closure, part of the Corby relief road project, takes place during half term.
Council bosses came in for criticism for enforcing the previous closure at the same time as the schools returned after the summer holiday.
The work will be in two phases, the first shutting the A43 between Stanion and the Holiday Inn followed by a closure south towards Geddington.
A Northamptonshire County Council spokesman said: “Since the first closure at the Stanion Island, the essential new drainage and kerbing works have been completed and this latest closure will allow the final Tarmac surfacing and white lining, to be completed.
“The closures will be over a four-day period, weather permitting, and will take place during the October half term school holiday when roads are relatively quiet.
“As before, the closure will take place in two phases with each phase scheduled to last for two days.
“Three-way traffic lights will be in place for the duration of the works.
“The first phase, starting on October 28, will see the work taking place on the northern side of the roundabout, with phase two seeing work on the southern side.
“Advanced warning signs will be put in place in the week leading up to the closure, to alert people to diversions and the A6003 will be fully open to accommodate traffic.”
