More than 25 tonnes of litter has been removed from alongside the Llan Y Pwll Link Road.
The litter, which had been thrown from cars, was collected as part of recent maintenance works carried out on the stretch of road.
As part of the work damaged traffic signs and crash barrier have been repaired, along with grass cutting and litter picking.
Workers lives are put at risk when picking up litter and drivers are being urged to keep their rubbish with them rather than leaving it at the roadside risking the lives of workers that haver to collect it.
Cllr David A Bithell, lead member for environment, is urging people to dispose of their waste properly and to not throw it from their car window.s
He said: “Most drivers who throw litter from their car windows don’t think about what they are doing or the fact that someone will have to come and collect it.
“I hope residents and visitors appreciate the costs incurred by local councils when collecting litter, at a time of great financial pressures.
“We ask members of the public to please dispose of their litter properly.
“I would also like to thank all staff for their hard work on the Llan Y Pwll Link Road over the last couple of weeks.”
