[Talk-us] Historic 66 as highway=trunk in OK

[stevea]

I chime in as a North American (Upper Midwest, originally) that highway=trunk is a not-especially-clear semantic in OSM (here, let's say the lower 48).  I understand the history of the tag but agree it is used to mean many things, widely, including in the states/regions/areas Joseph mentions; it's a rich topic.

So far, discussion about expressway and motorway have been tangentially helpful (to me, maybe others).

We had to go "trunk is fuzzy in the USA" there, didn't we?  Yeah, we did, I guess.  Tag.  Tag well.

I consider whether to enter Silicon Valley's expressways (G routes) as an example of the Urban/Suburban Expressways in our expressway wiki.  Interesting bit o' history about those (they are the second of three tax phases of becoming-freeway).  They seem sort of frozen where they are now but they do get special, real-time data fed, kinda-cool lane signage which keeps traffic flowing.  Bikes are welcome on some, yes.

Actually, bike networks in Silicon Valley are an interesting construction project, both in the real world and OSM.

Tagging is tagging and discussion about tagging is discussion.  Thanks for good discussion.
