Speed cameras set up on A75 between Creetown and Newton Stewart

It is expected the cameras should be up and running by the middle of August.

Alan Bowater, area manager for the west safety camera unit, said: "Temporary average speed cameras have proven to be an effective tool in improving road safety across Scotland.

"Their deployment on routes such as the A82 and the A836 has led to notable reduction in dangerous driving and injury collisions.

"These systems are a vital part of our strategy to address speeding and protect all road users - especially in areas where permanent infrastructure may not be in place."
