I suspect it was perhaps due to budget constraints or they think there not enough traffic yet for a full cloverstack

Another point to mention, is AB-201/Stoney trail is already marked on Mapnik while Google maps didn't show the newly completed gap (and they don't show the parts of A-50 who opened last Fall), you can view it via ACME Mapper http://mapper.acme.com/?ll=51.14382,-114.11310&z=12&t=K  (you can compare directly by clicking on "plan" for Google maps and "Mapnik" for Mapnik, I wish Acme mapper would include Bing as well, we'll have more fun to check ;-) )

On a off-topic note, Google maps did some change on their road markers, Quebec autoroutes are now blue and provincial/regional highways are now green, same for New Brunswick trunk routes and P-E-I highways besides TCH-1
