Cool info Mersar. Thanks.
The only reason that I thought Morley Trail continued to Cochrane (and beyond to Morley obviously) was because there is a little section called Morley Trail in Dalhousie:
I figured it was just a long lost segment that remained after Crowchild made its way through, but I have nothing to back it up.
My Dad seems to remember Edmonton Trail actually heading out of town to the North when he came to Canada, but again, I've got nothing to back this up. This would have been slightly pre-Deerfoot I think.
Mersar: I assume that you're a bit of a cartographer yourself (from the Open Street Map link in your sig). Do you know of any old city maps online anywhere? It is pretty neat to see what the road network looked like in previous eras.
One trail that I bet nobody has heard of is Contumacious Trail.
It appears to be a mapping error by Navteq. Spotted it on my GPS one day while driving in Crowfoot:
