[Talk-us] Questions about tagging local streets as US and statehighways

[Mike N.]

Some great questions here!

   I think the ref tag is technically not required when relations are 
present.  I'm not an expert - proper rendering might be some time away yet 
on the default Mapnik / Osmarender.

  The convention for highway network relations is just to use "278" - the 
'network' portion is combined if / when required.  In Potlatch, it currently 
displays as a member of
  "US:US US 278"

   I believe this is currently just a rendering problem.
