Drivers, local people and business owners are being invited to share their views on plans to upgrade part of the A47.
The consultation, which will take place for a total of six weeks, begins on Thursday, February 27.
Highways England announced in 2017 its preferred option for dualling the corridor.
They hope to dual the five miles of road between North Tuddenham to Easton and adding two new junctions in as part of a £300 million upgrade plan.
A spokesperson from Highways England said: "The upgrade will save up to seven minutes on journeys, will improve safety, and will boost the economy."
