A section of the A17 will be closed at night for three weeks for resurfacing works.
Work on the stretch of the road between the county boundary west of Beckingham to the A17 Sleaford Road junction will start on Monday, November 20.
A full night-time closure will be in place from 8pm to 6am, Monday to Friday, subject to weather conditions.
Local access to Beckingham will be maintained throughout the works from Sutton Road to the south and Sleaford Road to the east.
The signed diversion route for the closure will be via the junction of the A17 and A15 at Holdingham roundabout north to the A1434/Newark Road to the A46 back to the A17, and vice versa.
Councillor Richard Davies, responsible for highways at Lincolnshire County Council, said: “As part of these works, we will be resurfacing a section of the A17, which is one of the county’s busiest roads.
“This will involve replacing road surfacing that is nearing the end of its serviceable life.
“We will do everything we can to minimise disruption and ask for your continued patience while these works are carried out.
“We also encourage road users to take note of and use the signed diversion, as this is the most suitable and safest route to follow to get from point A to B during the works.”
