• On Monday to Friday nights from 22 to 29 August, the A1 will be closed northbound between Wallyford and Old Craighall Junctions, with a diversion route signposted via the A6094, A68 and A720. This diversion will add approximately 2.2 miles and 6 minutes to affected journeys.

Road users wishing to join the A720 will be diverted between Old Craighall Roundabout and Millerhill Junction through Wallyford via the A6094 and A68. This diversion will add 5 minutes and 3.6 miles onto affected journeys.

Emergency services will be given access through the works at all times.

Relevant stakeholders have been consulted in advance to make them aware of the plans.

Tommy Deans, BEAR Scotland’s South East Network Manager, said: “These surfacing and bridge joint improvements will help to address defects on this section of the A1 and will greatly improve the experience for motorists.

“It is essential for safety that we close the road during these works, however we’ve arranged for the project to take place overnight to minimise the impact.

“We thank motorists and the local community in advance for their patience and understanding. We’ll do all we can to complete the work as quickly and safely as possible.”
