The slip road from the A720 Edinburgh City Bypass onto the northbound A1 at Old Craighall Junction will be closed for carriageway repairs on the night of Friday 10 December.
This closure will be in place from 20:00 on Friday 10 December until 06:30 on Saturday 11 December.
A diversion for traffic wishing to join the A1 northbound at Old Craighall will be signposted via the A1 southbound, returning northbound from Wallyford Junction.
Emergency services and other relevant stakeholders have been consulted in advance to make them aware of the plans.
Tommy Deans, BEAR Scotland’s South East Network Manager, said: “It is essential that we close the slip road during these works to ensure the safety of road workers and motorists, however we’ve arranged for the work to take place overnight to minimise the impact.
“We thank motorists and the local community in advance for their patience and understanding.”
