Overnight roadworks will take place on the A17 Washway Road in Fleet Hargate and Long Sutton next week.
The package of improvement works to replace worn out carriageway will start on Monday.
The works will be carried out in two separate phases, with work expected to be complete by Saturday, March 24, subject to reasonable weather.
The first phase of works will take place between Hurn Road and Lowgate in Fleet Hargate from Monday, February 19 to Friday, March 9.
The second phase will take place north of Lutton Garnsgate junction to south of Delph Road from Monday, March 12 to Saturday, March 24.
For both sets of work, temporary traffic lights will be in use from 7pm to 6am, Monday to Friday, except for the final five evenings of work in Fleet Hargate, which will be carried under a road closure.
The road will be opened to traffic outside of working hours and access to properties will be maintained throughout the works; however, access may be limited depending on where work is taking place.
The signed diversion route for the Fleet Hargate closure will be via A17 / A151 / A16 / A47 / A1101 / A17 and vice versa.
A temporary 10mph speed limit will also be enforced during work hours for both phases of work, along with a temporary 40mph speed limit during the day.
Finally, as part of the Long Sutton works, Delph Road and Lutton Garnsgate will be closed during work hours.
The signed diversion route for this closure will be either via Garnsgate Road/B1359 or Burlier Gate/St James Road/B1390, depending on where work is taking place each evening.
Coun Richard Davies, Lincolnshire County Council’s executive member for highways, said: “The improvements we’ll be carrying out on Washway Road from February to March are essential to keeping the A17 through Fleet Hargate and Long Sutton up-and-running.
“Taking care of essential maintenance now, as part of one package, will mean less disruption for residents and commuters in the future.
“We’ve planned these works to take place overnight to keep disruption to a minimum, and ask for your continued patience through the project. We also ask drivers to remain conscientious of the traffic management and restrictions in place for the safety of both the workforce and other road users.”
