Scottish transport minister Derek Mackay has announced £3M will be invested in the A83 this year to improve resilience and mitigate the effects of future landslides.
The area around the landslip-prone Rest and Be Thankful pass has already received a £9M investment in recent years.
The additional money will be used for landslide mitigation work in Glen Kinglas and at Strone Point corner.
Speaking at a recent meeting of the A83 Task Force in Arrochar, Mackay asked for further work to be carried out into what extra measures could be used to ensure continuity of access to Argyll and Bute.
He said: “The Scottish Government is firmly committed to mitigating the effects of landslides on the A83 and this further investment will allow us to take forward more work at the Rest and Be Thankful and at other areas prone to landslides.
“The most recent landslide events have shown us that we can keep Argyll open for business. The netting at the Rest and Be Thankful has prevented thousands of tonnes of rubble reaching the road and this has kept disruption to a minimum. The Old Military Road Diversion Route has shown its worth and brought time savings for the drivers who have made use of it.
“Our efforts to improve conditions along the length of the route are continuing with £32M spent in the last seven years. We are committed to progressing work at Strone Point, Erines and Dunderave in the coming months with the overall aim of keeping traffic moving and building greater resilience into the A83 as a whole.”
