A road was closed off in Lancaster after a mud spillage.
Police shut a section of Quernmore Road on Thursday after dirt fell off a contractor’s wagon onto the icy road surface.
A Lancashire County Council spokesman said: “The contractor had been dealing with it themselves but it became complex so we needed to clear the road.”
He said he hoped the road would be reopened by Friday afternoon.
The closure followed an accident on Quernmore Road on Thursday morning when a car collided with a hedge. Nobody was hurt.
