It still remains a mystery why a hole appeared in a Grantham road last week.
The hole appeared in Castlegate between the Bluegate junction and Middlemore Yard junction on Tuesday last week. The road has since been closed between the two junctions with local access allowed.
A small hole just a few inches across appeared in the road but engineers discovered a much larger void underneath which has been put down to subsidence.
A spokesperson for Lincolnshire highways said: “Anglian Water have finished their investigation and concluded that the subsidence has nothing to do with the sewers. So, at this stage, it’s not clear what has caused the void. We’re currently making the necessary arrangements with our contractor, with a view to starting the repairs early next week.”
Diversions are in place via Bluegate, Swinegate, Watergate/High Street and Finkin Street.
