A Mansfield street could be closed until next week after a 12ft-deep sink hole appeared in the middle of the road.
Severn Trent Water are still busy trying to fill in the collapsed section on Normanton Drive, off Eakring Road, which appeared last Wednesday.
Police were quickly called to block off the road, before Nottinghamshire County Council workers were called out.
They determined that it was a collapsed sewer and therefore the responsibility of Sever Trent.
A spokesman for the water company said: “We’ve been working hard on the sewer collapse in Mansfield over the weekend.
“We’ve filled in most of the hole created by the collapse, leaving us with a much smaller area to concentrate work in.
“As the sewer pipe is around three metres down in the ground, we need to make sure the site is properly managed so that our teams can work safely.
“Work is ongoing to continue digging down, while making sure the area is safe. Once we’re down to the pipe, we can get to work on repairing it.
“We expect that the work will take a little while, as it’s such a tricky job to get at the pipe, and so it may take into early next week.
“We’re really sorry for any inconvenience that this may be causing, but it is important that we do this job properly to avoid any pollution to the surrounding area.”
Although it appears to only measure about a foot wide from the surface, it was more than seven feet in length and 12ft deep.
A woman who lives almost opposite the sink hole described it as being like an ‘underground cave’.
Jane Anderson said: “It was a neighbour who spotted it, “When you look into it, it looks like an underground cave, it looks like it’s been excavated.
“What’s worrying is that it looks like nothing is supporting the road surface.
“The Tarmac looks so thin around it. It’s frightening.
“If the road had been covered in snow you would not have known it was there. This is a heavily-used road.”
Indeed, parents use the road to pick up their children from the nearby Abbey Road Primary School.
A diversion has been put in place by the council for motorists.
