Resurfacing works have commenced on the A1 trunk road in Berwickshire, between Chapelhill Farm and Cockburnspath Roundabout.
These works represent a £160,000 investment by Transport Scotland.
Preparatory works started on Sunday, and were carried out under a single-lane closure and two-way traffic was maintained.
The resurfacing works were due to commence on Monday and will be carried out each week day between 8am and 4pm, utilising stop/go traffic management and lane closures.
For the safety of the travelling public, lane closures will remain in place overnight, and we ask that care is taken when driving through these works.
No works will be carried out over the weekend of October 29/30 and all works will be completed on Friday, November 4.
A 40mph will be in place over the extent of this site for the full duration of the works, including overnight, for the safety of the workforce and the travelling public.
Minor delays are expected and BEAR Scotland will make every effort to ensure that any delays are kept to a minimum.
Ian Stewart, operating company representative for the South East Unit, said: “These works have been planned to ensure that the safety of the workforce is maintained while making every effort to minimise the disruption to the travelling public.
“We regret that there will be some disruption and would advise motorists to allow additional time for their journeys and plan ahead.”
Information signs will be used in advance and throughout the works to inform the travelling public.
