Repair work is to begin on the A77 near Cairnryan following damage from winter storms in 2014.
The road was affected at Marchburn near the boundary between South Ayrshire and Dumfries and Galloway.
No major works have yet taken place since traffic lights were put in place on the road and debris removed in 2015.
This is because of the size of the slope between between the road and Loch Ryan, created by the landslip.
TranServ have now announced that work to repair the road will start on Friday 3 November.
The road will be closed between 8pm until 6am on Monday 6 November to allow the repair work to start.
The traffic lights are expected to be lifted, and works finished by early 2018.
