[Talk-us] Separate relations for each direction of US & State highways.

[Martijn van Exel]

Hi James,

I had not thought of the Case of the Hidden Segments. It makes sense
to tag them, but would it not be more in line with general OSM tagging
practice to use role:signed = yes/no?

I think it's a valuable extension on the role discussion, perhaps you
can add a paragraph to the wiki page
http://wiki.openstreetmap.org/wiki/Highway_Directions_In_The_United_States
with an example? I found this photo (not ideal and I'm not sure if we
could use it on the wiki, but it's something ;)
