Thank you all for your comments. I will continue to research and adjust my tagging practices and try to meet current best practices. Although retired now, I used to design and install remote rural telecommunications systems in the areas I map, so I not only had to travel these areas, I had to analyze the terrain and interview the people that used them (outfitters, cabin owners, recreational travelers). That is why I insist there are roads of more importance than others, even if they look the same on an aerial map. OSM says on-the-ground knowledge is the primary goal, but it is difficult to convince someone of your ideas when they may not be obvious on a photo. I admit I have made classification mistakes in the past and can only hope to reduce the errors with more practice.

Thank you for your comments. The Bowater Resource Road at https://www.openstreetmap.org/#map=15/48.9899/-54.9031 is a better example of what I now classify as a tertiary way. The example you provided was indeed a mis-classification.
