A main road in north Wales will be shut until next week amid fears of more landslips, causing long diversions for drivers.
The road was reopened on the weekend, but has been shut again
The A470 between Dinas Mawddwy and Dolgellau was closed on Friday after heavy rain caused a landslip to block the road.
Motorists are now having to take a major diversion along the A487, which can take nearly an hour.
Work is now under way to replace a safety fence alongside the road.
The A470 is one of the main routes between north and south Wales.
Friday's landslip occured near the crest of the pass at Bwlch Oerddrws, but the road was reopened over the weekend using temporary traffic lights.
About 200m of safety fencing was removed by the slip, and the decision to shut the road again was made on Tuesday, after an inspection by a geotechnical engineer.
