Overnight closures are taking place on the A14 this weekend as part of the ongoing A14 widening project between junctions 7 and 9 near Kettering later this week.
In addition, the Highways Agency said contractors are closing the eastbound junction 8 entry and exit slip roads for three days from Friday, July 4.
That closure is taking place between 8pm on Friday until 6am on Monday morning, July 7, and motorists are being advised to add 15 or 20 minutes onto their journey.
The overnight closures take place between junctions 7 and 9 on Friday, Saturday and Sunday evenings from 8pm each night until 6am the following morning.
Again, the Highways Agency says this will add about 15 to 20 minutes to journey times.
A spokesman for the agency said: “Contractors have completed installation of the contra-flow system which is now fully operational, 24 hours a day.
“The contra-flow system will be used to provide the necessary working space for the safe construction of the main earthworks.
“Installation of sheet piling, which is the retaining wall and foundation for the noise protection fencing which will be installed as a follow on operation to mitigate the effects of the widening scheme has finished for now.
“Unfortunately, the installation of sheet piles has been a noisy operation and we are aware that residents may have experienced vibration as well. For this reason, we undertook these works during the day to limit the impact to local residents.
“We would like to take this opportunity to apologise for any inconvenience caused by this.”
