A woman in Ingol says a sinkhole she reported has not been fixed after nearly a month.
Emma Wilkinson said the road collapse in Mayfield Avenue had now seen a second hole appear.
Reported to Lancashire County Council in mid-June the hole has now grown in size.
Emma said: “I reported it and since then the void under the road has really been revealed, especially since the second hole.
“They’ve put a barrier up but it’s worrying the road is just melting.”

A spokesman for Lancashire County Council said: “We’re aware of this issue and suspect it to have been caused by the ground beneath the road being washed away due to a water leak.
“We have made United Utilities aware of the issue and they are due to investigate further.”
