One lane of the A83 Tarbet to Campbeltown route at the famed Rest and Be Thankful has reopened following a landslip last month.
About 10 tonnes of debris crumbled onto the road, with work immediately beginning to clear the carriage and make the area safe.
Now one lane has reopened following inspections by specialist engineers and police.
Motorists travelling the route will pass under traffic light control whilst mitigation works continue, with the latest project to install a new catch-pit for falling debris underway.
A major programme of works has now been completed after approximately 10 tonnes of debris slid down the hillside on August 4 with boulders the size of cars exposed.
A helicopter was even brought in to help stabilise boulders and make them safe.
A temporary debris barrier has been erected to protect road users and a catch-pit is being excavated at the foot of the channel to provide further safety measures.
The source of the landslip was located around 650-feet above the A83, which split into two main channels as it spread out in a “fan effect” down the hillside.
Around 2,000 tonnes of debris was prevented from reaching the carriageway after it was contained in one of the catch-pits, with around 1,500 tonnes impacting the A83 and a further 2,000 tonnes of material washing onto the Old Military Road, the usual diversion route.
A team of around 50 workers have been working round the clock to complete repair works as well as keeping the Old Military Route running safely during the closure period.
Eddie Ross, Bear Scotland’s north west representative said: “We’re pleased to safely reopen one lane of the A83 after a full safety assessment with representatives from Police Scotland this morning.
“Teams from multiple organisations have worked round the clock in all conditions to complete the programme of complex repairs in the area and keep the Old Military Road and other routes into Argyll open.
“Engineers will continue to carry out further mitigation work on the hillside above the road as well as at the next catch-pit location to provide further landslip resilience on the A83.
“As ever, we thank the local community for their patience and support while we worked to address the repairs at the Rest and encourage them to drive safely through the Rest and Be Thankful teams complete the remaining mitigation work at the site.”
