The £15,000 refurbishment project, which will be carried out on the A7 at Mosspaul Gabion Wall, starts at 8 am on Monday for two weeks.
And the southbound lane of the busy carriageway will be closed for the duration of the works, with all vehicles directed to use the northbound lane under a temporary traffic light system.
A spokesman for Amey, who will undertake the work, said: “Around 2000 vehicles use this section of the A7 each day and this investment, with a value of approximately £15,000, will ensure motorists experience greater journey time reliability, continued safety and comfort.”
The work will be undertaken to a 40 metre long stretch of the wall, which supports the
carriageway above the steep side of the River Teviot.
And the scheme has been planned in consultation with Police Scotland, Scottish Borders Council, Dumfries and Galloway Council, SEPA and the Fisheries Trust.
