I can’t seem to get google maps to remember the routes i put into it but there is basically 2 ways i’d recommend going.
1 From Westhill take the country roads accros to the A96 round-a-bout at Blackburn then take the A96 into Dyce – Probably cutting up left at the Marshal Trailers junction (the one just past the speed camera on the way to the airport round-a-bout)
2 Head out of Westhill the other way A944 to Kingswells then left over towards dyce at Kingswells round-a-bout. At the T Junction you come to after Kingswells take a left then at the top of the hill take your first right and this will bring you out onto the A96 on the Aberdeen side of the Airport round-a-bout into the slow moving trafic heading to the industrial estate.
Rather than the first right you could continue over the hill and cut through the SAC at Craibston but they can get a little shirty about through trafic.
