The A4067 carriageway is back open under temporary traffic management following a landslide that closed the road on Monday, April 8.
The majority of the debris has been removed and barriers have been put in place to protect from any potential further landslides.
A spokesperson for Powys County Council has said: “Most of the debris has now been removed and barriers have been put in place to protect road users from any potential further slips.
“Work will continue over the next couple of weeks to stabilise the bank to allow a full reopening of the road.
