Work is to get underway to clear a number of huge trees from above the A82 as it passes Loch Ness.
The work at Primrose Bay north of Alt Sigh will start on Monday, November 14 and will be carried out by Forest Enterprise Scotland (FES).
Motorists are being warned to expect delays during the work.
The operation was due to start in September but was delayed because by work to secure a private water supply to the site.
The work is likely to take up to 18 months to complete and will be followed up with slope stability operations.
The work is the latest in a series of stabilisation projects along the A82 between Inverness and Fort William by FES.
Project manager Alex Macleod said the work will be particularly challenging due to the size of some of the trees, which weigh up to 10 tonnes.
He said: “We have been doing a lot of work behind the scenes to upgrade the forest access road and secure private water supplies and we are at the stage now where felling work can begin.
“Things don’t get any easier for us above Loch Ness and this will be a challenging operation given the size of the trees and the steepness of the terrain. Some of the trees weigh nearly 10 tonnes in weight.
“As with other A82 operations traffic management will be required below the site Monday to Friday 7.30am – 5.30pm to ensure the safety of road users during felling; this will include short periods of road closure in both directions of up to 10 minutes.
“Traffic management will also be deployed at Alt Sigh itself on Saturdays to help timber lorries move safely in and out of the forest entrance though any impact here will be minimal.
“Traffic management will be removed for the Christmas, Easter and the summer holiday periods but we would like to apologise in advance for any inconvenience our operations might cause at other times.”
