The A15 south of Lincoln is set to be closed for four nights later this month to allow for roadworks associated with the runway replacement project at RAF Waddington to take place.
In March 2014, it was announced that RAF Waddington would undergo a £35.4m operation to rebuild its runway and improve airfield facilities, which had not been upgraded since the 1960s.
There will be overnight closures on the A15 from 7pm to 6am from January 22 to 23; January 23 to 24; January 29 to 30 and January 30 and 31.
A diversion will be in place via the B1178 to Harmston and the A607 to Bracebridge Heath, and vice versa.
Lincolnshire County Council has said that the closures are planned for the weekend to reduce disruption for drivers, who are advised to allow extra time for their journeys.
