Contractors helping to clear-up the Rest and Be Thankful are hopeful the road will be reopened in the middle of next week.
Workers are hoping to continue repairs for 24 hours a day in order to get it opened up as soon as possible.
The A83 Tarbet to Campbeltown road has been shut due to a large landslip on Sunday.
Work has been ongoing since then to repair the damage caused.
A short section of embankment supporting the road was eroded due to large volumes of water and debris washing over the edge of the road.
Engineers have designed a repair and that is being implemented by teams on site today.
Most of the debris has been removed which means that a proper deadline for the work to be completed can be created.
Early indications show that the work to reopen the road should be completed around the middle of next week, subject to weather conditions.
The Old Military Road local diversion route is to remain in use until then, although it will be reviewed on a daily basis.
Eddie Ross, Bear Scotland’s north-west representative said: “Teams are making good progress on site with clear up and repair works which has enabled further assessment to be carried out to determine the extent of the damage caused by the recent landslip.
“Initial assessments indicate that the work should be completed around the middle of next week, depending on weather and other developments.
“The Old Military Road will remain in use tonight, however we’ll be continually assessing and monitoring the hillside along with our geo-technical specialists to determine if it is safe for us to continue to keep the OMR in operation.
“We thank the local community and road users for their patience while we address the landslip at the Rest. Argyll remains open for business and our teams will continue to work around the clock to reopen the A83 as quickly and safely as we can.”
