A 15 metre section of the road on the Knoydart Peninsula collapsed on Tuesday 24 October.
This 4.8 mile single track road between Scottas and Airor is a lifeline road for the communities beyond the slip which include Airor, Doune and Sandaig.
The Highland Council's Roads Inspector has been on site on Wednesday 25 October and carried out an initial inspection.
A full engineering assessment is planned for Thursday 26 October.
Preliminary plans have already been made for the transfer of staff and materials to the area and contact has been made with a local landing craft operator.
Due to the geographical and physical constraints it is anticipated that the repair will take several weeks depending on the availability of specialist equipment and materials.
In the meantime the local community have set up a “road shuttle” arrangement with a vehicle on either side of the landslip.
