Work to stabilise the steep hill beside the A82 in an area which suffered a serious landslide in October of last year is due to start later this month.
The landslips at Glen Righ and nearby Corrychurrachan, south of Fort William, closed the busy trunk road for 30 hours leaving motorists facing a 162-mile diversion.
At the time, local people suggested that tree felling operations carried out by Forestry Commission Scotland on a steep bank above the Inverness to Glasgow road could have contributed to the incidents.
But the commission claimed the work carried out at Glen Righ had saved the landslides from being more severe.
And it yesterday confirmed that the landslip location forms part of the area covered in this next stage of work, but it said the incident had not required any change in the planned programme.
Tree-felling work at Geln Righ restarted after the Christmas break yesterday.
And the commission’s geotechnical team will be returning to work on the site from Monday, January 19, as part of the wider project, which involves making safe and harvesting trees on the hillsides above the A82.
Project manager, Alex Macleod, said: “Harvesting operations have progressed really well over recent months and we’ve seen the team remove some very large trees safely away from the A82.
“However, we now need to carry out further slope stability work on the areas that have been recently felled.
“As before, this phase of work will involve rock scaling, netting and bolting, but will also see the installation of a permanent catch fence on the steepest part of the slope.”
He added that traffic management on the A82, north of Corran Ferry would continue until April 2, but said there would be less requirement for traffic to be stopped in both directions for short periods as happened during harvesting.
Most of the area that has been harvested is to be replanted with broadleaved trees, which will help stabilise the slopes for decades to come.
A spokesman for the A82 Partnership said: “We understand that this current phase of the Forestry Commission works, which will take us up to Easter and beyond, will mark the end of the works at Glen Righ.
“Hopefully we will see the end of the traffic management north of Corran before the beginning of the summer tourist season.”
