A local diversion will be in place via: A70, B7008, A71, A704, A706, A721 and A70

Head of Roads, Fleet and Transportation Services, Colin Park, said: “We apologise for any inconvenience that may occur during these essential road improvement works.

“We would request that all road users allow additional time for all journeys which involve the use of A70 Carnwath during the period indicated and that they plan their journey accordingly.

“I am sure road users will appreciate the much-improved condition of the road when the works are complete and thank them for their patience.”
