The site of the incident is a few hundred metres from a area hit by a landslip in 2005, which closed the road for several days.
It is on a stretch that cuts through the steep pass at Bwlch Oerddrws, heading towards Dinas Mawddwy.
Emlyn Williams, the network area manager for the North Wales Trunk Road Agency, said teams were on site trying to assess the situation.
"The landslide happened on Tuesday night, and we had a few lorries that couldn't get through and had to be helped," he explained.
"The road is likely to be closed for at least the early part of the day. We have experts on the way to the area to see how quickly it can be resolved."
He said it would be later on Wednesday afternoon before the agency would be able to assess the initial reports.
"There is something of a history of landslips on this stretch," he added.
"The road is effectively cut in to a mountain, and the geography means it is prone to things like this."
Local councillor John Pughe Roberts said he had seen the impact of the landslide, which has strewn mud and rocks across the carriageway.
"It is nature - what can you do about it?" he said.
"It's going to mean a long drive around for those who need to get past."
