text: bugs are bugs.  the entire road to the southwest was duplicated and joined (p2 shows junction nodes distinctly with a ring).  the exceptions are where new drives were added in maybe three places.
  
  the two ends of the way have the differing turn restrictions that caused me to abandon ship.  if you understand the turn restrictions, i could return to my effort.
  
  from some analysis i just did in colorado, it appears p2 presents the lower-number older of two overlapping ways as being on top (tagged shed atop untagged outline).
  
  on the other hand, iD seems to put the newer of the two ways on top and active, so the added drives were solely connected to the newer addition.  i'm assuming the others were added before the split.
  
  do you know josm (i don't) or do you know if it's possible in iD to raise a non-active way to be the active one?  if so and if you understand turn restriction relations, i'd ask if you could study what amazon wanted to add, and to note what's on the older version.
  
  that can probably be determined from the osm page for both ways.  they had just edited two hours before i started to unglue things, so i'd prefer to figure out their hours - as i write this and the us sleeps, i know there is happening the several dozen seo spams and onosm abuse from eastern europe into notes flood, that i can soon swat.
  
  i should study their hours behind the changeset commentaries...
  
  more when i decide what to do.  probably delete the split way and point out where it differed.  must think first...
  
  thanks
