Residents in the Scottish villages of Airor, Doune and Saindaig face the prospect of being cut off for several weeks following collapse of the road leading to the communities.
Highland Council has said that a 15m section of the road at Soldiers Rock on the Knoydart Peninsula had collapse.
The council said: “Our roads inspector has been on site this morning and carried out an initial inspection. A full engineering assessment is planned tomorrow. 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.”
