Sinkholes

The road in Wokingham was shut in August after problems were found in an underground sewer.

Part of Port St Mary's Four Roads is shut for excavation, the infrastructure department says.

The 100ft (30m) deep hole opened up on a driveway in Greenfield, Darwen, in September.

Aging mines and heavy rain make collapses more likely and there have been several in recent months.

Highways officers warn that the cavities beneath may be much larger than they appear on the surface.

Hampshire County Council say it is working to sort the complex issue which also involves gas pipes.
