Good job.  :-)  Local mapping and checking multiple sources is a good
way to do it.

Responding with only general impressions as I have no local knowledge.
 Where a trail shares another bit of infrastructure, like a road, I'd
probably tag the road sections first, in a way that would be expected
for the road.  Then I'd split the way(s) where the trail joins and
leaves the road(s).  I would not change the tagging of the road ways.
I would add the road ways between the trail entry and exit to the
trail route relation.

I find that process to be a simple way to tag the aspects of the way
(surface=asphalt, lanes=2, oneway=yes, etc.) and the aspects of the
route name="Trans Canada Trail", horse=yes, bicycle=yes, etc.

Does that help?

Best regards and happy mapping,
