Consultation has been carried out with emergency services and other relevant stakeholders to share information about the project in advance.
Tommy Deans, BEAR Scotland’s South East Network Manager, said: “It is essential for safety that we close the carriageway while these works are carried out, however we’ll be taking advantage of the closures to carry out as many routine maintenance tasks as possible at once.
“We’ve also split the works into phases so that only the minimum length of carriageway has to be closed on any given night.
“If you are planning to use the A1 at night over the next few weeks, our advice is to check what restrictions will be in place and allow extra time for your journey if necessary.
“We thank road users and the local community for their patience and understanding.”
