A road in Holbeach is to be closed for four weeks to reconstruct the footpath.
From Monday June 5 the B1515 Fleet Road will be closed for the duration of the works between Holbeach and Fleet Hargate.
Lincolnshire County Council says resident and business access will be maintained, but a diversion will be in place via the B1515, B1168, A17, B1515, and vice versa.
Coun Richard Davies, executive member for highways, said: “This section of path alongside Fleet Road is beginning to show signs of subsidence, so we’re taking action now before it deteriorates any further.
“Pedestrian safety is paramount, but sorting this subsidence will also make the maintenance of the adjoining road easier going forward.
“Due to the nature of these works, we’ll have to implement a full road closure for the duration of the project to keep our crews safe. I’d like to thank everyone effected for their patience, and apologise for any inconvenience caused.”
