Maintenance work begins this evening, Thursday September 17, to improve the road surface on the A1 southbound carriageway, south of Spott roundabout near Dunbar.
Works will take place between 8pm today and 6am tomorrow, Friday September 18.
The work requires a full closure of the southbound carriageway.
There will be a signed diversion in place.
Traffic travelling southbound will be taken off at the Thistly Cross roundabout onto the A199 then the A1087, re-joining the A1 at Little Pinkerton junction.
Further works are planned to take place between 8pm on Friday September 18 and 6am on Monday September 21.
This work will also require a full closure of the southbound carriageway, while there will be a contraflow system in operation on the northbound carriageway.
During these works the A1087 junction will also be subject to restrictions, with a signed diversion in place to assist road users.
Scottish Borders Council have planned these works in consultation with Police Scotland.
The council said that around 12,000 vehicles use this section of the A1 each day, and this investment, with a value of approximately £315,000, will ensure motorists experience “greater journey time reliability” and “continued safety and comfort”.
