Drainage improvement and embankment works will close part of the A68 this weekend.
The main A68 at Mervinslaw near Camptown will be closed to between 7am and 5pm on Saturday and Sunday.
The temporary traffic lights, which have been in place since the road was damaged in floods earlier this year, will be removed once these works have been completed.
A spokesman from road operator AMEY said: “This maintenance programme will benefit around 1,068 vehicles that use this route each day; by ensuring improved driving conditions and a reduction in future maintenance requirements.
“The scheme requires a full closure of the A68 with a signed diversion route in operation.”
Southbound traffic will leave the A68 at the Cleikimin junction, north of Jedburgh by Ancrum, and travel along the A698 to Hawick before proceeding via the A6088 to the junction with the A68 at Carterbar. The same diversion route is in place in the opposite direction.
This work, with a value of £5000 is being carried out in consultation with Transport Scotland, Traffic Scotland, the emergency services, bus operating companies, local elected members and Scottish Borders Council.
