An internal investigation is underway after a large industrial machine toppled in the road.
Road contractors had to be called when a piling rig tipped over and blocked both sides of the road on D’Urton Lane on Monday at 3pm.
And now construction company Hochtief, which owns the rig, says it is looking into the cause of the incident.
A spokesman for the company said: “On Monday at around 3pm piling rig fell over on its way to our A6, Broughton Bypass site.
“We are now carrying out an investigation into the cause of the incident. The vehicle will also be assessed and no-one was harmed in the incident.
“We are unable to comment further until the investigation has finished.”
A Lancashire Police spokesman said: “We were called around 3.40pm on Monday, July 18 to reports of highway disruption in D’Urton Lane, Broughton.
“A machine had fallen off a blue Scania lorry and was blocking traffic in both lanes.
“Roadwork contractors helped to remove the obstruction.”
