Investigations are underway after part of a road sunk by 100mm in the West Country.
The highways team at Somerset County Council closed a section of Seymour Street in Wellington after discovering the 9m2 depression last Tuesday.
They are attempting to work out what caused the road to sink and what damage this has caused.
Councillor David Fothergill said: “It’s always regrettable to close a road, but the public’s safety is our number one concern and we’ve had to take immediate action as a precaution.
“Hopefully we can identify the cause of the problem very soon so that the road can be fixed or reopened as quickly as possible.”
