[Talk-ca] Highways in Yukon

Sure, i'll help with that.

The Dempster Highway portion that physically has the 'TCT logo' needs
to have a relation route.

However, it CAN be tagged as a 'rcn bicycle route' because in that
province it is a 'regional cycle route'.

If it is not provincially designated 'state=proposed' works just fine.
And even route=ncn state=proposed would also work.

On a national scale, the TCT is not a 'National Cycle Trail' but a
'mixed use greenway with different designated uses'
(that in turn, makes me pull my hair out)

Also, the entire highway should be tagged with a relation route, for
its highway designation.

The actual name of the road should not say 'Trans Canada Trail'.

When your done marking where where the physical road is, please let me
know, then we can figure out what the best answer is. :)

Overall, my aim is to get the entire network that is bicycle=yes as
well as foot=yes for the entire country, so at a minimum, the actual
road/track/path/footway/cycleway is actually mapped first.
Then we can muck about with relations & labels at a later date.

So ya, maybe the better answer is to say 'yup, sure You are local
expert, since i have never been there, its not my place to say how it
should be tagged'.

Yup, its what i do.

Hopefully that helped a little.

Solving the worlds largest puzzle isnt exactly the easiest task :-)

Mapping the country in painfull detail is actually easier than sorting
the Trans Canada Trail :-)
