A 250-metre stretch of carriageway around the Buslingthorpe Road junction will close for resurfacing works.
During the improvements, taking place on Thursday, August 17 and Friday, August 18, a 25-metre section of Buslingthorpe Road will also be resurfaced.
Mark Heaton, programme leader for surfacing and patching at Lincolnshire County Council, said: “These areas of the carriageway are worn out and need to be repaired ahead of future surface dressing.
“For safety, there will be a road closure in place during the works. Traffic on the B1202 will be diverted via the A631, B1225, A157 and A158, while vehicles on Buslingthorpe Road will be directed via Mill Lane and the A631. Gatemen will be on hand to advise and assist.
“We apologise for any inconvenience caused and recommend drivers leave longer for their journeys.”
