Consultation has taken place with relevant stakeholders in advance of these works to make them aware of the traffic management arrangements and to minimise any inconvenience.

Tommy Deans, BEAR Scotland’s South East Network Manager, said: “These ongoing works on the M90 will address defects in the road drainage system, creating safer journeys for motorists.

“It is essential for the safety of road workers and motorists that we close these slips roads during the works, however we’ve scheduled closures overnight in order to minimise any disruption.

“We thank motorists in advance for their patience while our teams carry out these improvements.”
