A key route just outside of Oban is to be completely closed for a number of days from tomorrow.
Emergency works are being undertaken on the A828 between Ledaig and Benderloch, approximately two miles north of Connel Bridge, from 8pm on Friday.
Works are anticipated to be completed at some point over the weekend.
During Saturday and Sunday, the trunk road, including the footway and adjacent national cycle route 78, will be shut and a diversion put in place via the A85 from Connel to Tyndrum and the A82 through Glencoe to Ballachulish. Given the nature of the work, amnesties or timed openings are not possible, road bosses say.
A spokeperson said: "The closure is required to make a section of the high rock face in this location safe. Recent monitoring of the site has identified deterioration of the area surrounding a fractured rock mass 60 metres above road level. This has been assessed by geotechnical engineers and requires urgent attention to ensure the on-going safe operation of the A828 trunk road."
Temporary traffic signals were put in place on Wednesday as an immediate safety measure prior to undertaking the weekend works.
The spokesperson added: "As part of the works, extensive measures need to be put in place to protect the road and important utility services at the location from the potential impact from rock debris."
