Carmarthenshire County Council has said that work to stablise an embankment has begun on the site of a fatal landslide in October.
A small section of the A484 at Cwmduad, a rural road between Carmarthen and Newcastle Emlyn, has been closed since the landslide during Storm Callum in October in which 21 year old Corey Sharpling died.
Ground investigations have been underway to ensure that the embankments above the road can be made stable, including drainage and tree works. The operation also involved the recovery of a lorry earlier this week which was swept into the river during the storm.
The highway structure will now be assessed before any indication can be given as to when the road will re-open, the council has said.
Council officers have worked with external agencies, the landowner and insurance companies to secure the re-opening of the road as soon as possible.
Carmarthenshire County Council Director of Environment Ruth Mullen said: “We are now making progress in what has been a highly complex operation and legal process between the council, partner agencies and the landowner.
“We fully appreciate the impact this has had on the community, and we wish to reiterate that we have worked without delay to undertake site investigations in the immediate aftermath of the landslide, along with clearance and construction works to make the area safe.
“We are working as quickly as we can to re-open the road as soon as possible, and would like to thank those affected most sincerely for their patience.”
