The contractor’s representatives and Cllr Douglas had attended the meeting. The support offered involved publicising the businesses by various methods including social media. The construction work is scheduled to start in May 2020 and take 18 months. It will involve closing the right turn from Roseburn Terrace into Roseburn Street for a period of 12 weeks. The Council is expected to hold a further meeting with the traders."
