United Utilities is to investigate a fresh road collapse in Lancashire.
One lane has been closed on a section of the B62321 in Haslingden while engineers from the water firm use a CCTV survey to decide whether a sewer is to blame for the depression in the highway.
It comes just weeks after the A682 suffered a collapse just the other side of Burnley, near Junction 13 of the M65.
Ray Bennett, Lancashire County Council principal highways engineer for Rossendale, said of the latest incident: “People’s safety is our main concern and we must close one lane to make sure the road doesn’t collapse further under any vehicles.
“This will also allow the utilities company to investigate what has caused the collapse and carry out repairs to the road and sewer.
“We may have to close the road altogether and put a diversion in place if the investigations reveal a major problem, but we will keep motorists informed.”
A spokesman for United Utilities said: “We have agreed with the council to carry out a CCTV survey tonight to check whether the sewer is the cause of the depression of the road.”
