The Old Military Road in Argyll will close overnight as a safety precaution – just hours after reopening a landslip.
The route was closed on Sunday after more than 5,000 tonnes of material reached the A83 at the Rest and Be Thankful.
Traffic was reinstated at 6.10am this morning after the road was cleared overnight.
However, the Old Military Road is set to be closed again from 7.30pm due to conditions on the hillside above it.
From that time, all traffic will be diverted on to the standard diversion route via the A83, A82, A85 and A819.
Safety assessments will take place from 7am tomorrow to determine if it is safe to reopen the route again.
Eddie Ross, Bear Scotland’s north-west representative said: “Safety is our top priority, and following input from geo-technical specialists we have taken the difficult decision to close the Old Military Road as a precaution overnight tonight.
“The standard diversion route via the A83, A82, A85 and A819 will be reinstated from 7.30pm tonight. A full safety assessment will take place at 7am on Wednesday morning to assess if it is safe to reopen the Old Military Road.
“The clear up operation is progressing well which is allowing us to gauge the damage caused to the road, drainage and safety barriers. We will continue to give updates on this work as it progresses as quickly as possible.
“Safety has to come first and as ever we thank the local community and road users for their patience while we address the situation at the Rest.
“Argyll remains very much open for business and we ask road users to plan their journey in advance by checking Traffic Scotland for the real-time travel information.”
