Drivers face overnight delays on the A11 while its southbound carriageway is closed for improvement works.
Work will take place between the London Road Roundabout and Fiveways Roundabout, with closures on weeknights only and weather permitting.
The southbound carriageway will close between Elveden Bypass and Fiveways Roundabout from 8pm until 6am, starting Wednesday and continuing until Monday, October 5.
National Highways said the scheme includes refreshing faded road markings, replacing damaged road studs and laying high-friction surfacing.
It said work will help the A11 cope with traffic levels and remain well maintained.
Between 28,000 and 30,000 vehicles use this section each day, according to National Highways.
Drivers will be diverted via the A143, Mundford and A1065 before rejoining the A11 at Fiveways Roundabout.
A spokesman for National Highways said: "The first phase of resurfacing work alongside the Fiveways Roundabout project went so well that we're able to shorten our roadworks programme."
A spokesman for National Highways said: "Thank you for your patience while we complete these improvements to help keep journeys safer and smoother."
