The hole appeared at Gordon’s Street junction with Manor Road on July 28.
The road has been shut ever since and now they have been told it will remain so for at least another FOUR weeks.
A spokesman for Yorkshire Water told The Scarborough News: “Over the last few weeks we’ve been working to try understand the cause of the highway collapse on Gordon Street, Scarborough by using special cameras and equipment to see if the pipes underground are the cause of the problem.
“Following these investigations, we’ve identified that further work is required so we’ve started to set up the site to dig down to the pipes.
“The sewer pipes in Gordon Street are very deep – 8.5m - meaning the work required will be extensive and this is likely to last up to 4 weeks.
“During this time there will be additional noise, disruption and vehicle activity onsite – any help or concerns you may have can be answered by the team onsite and they will help to resolve them for you.”
