  Turn restrictions I had added were attempts to resolve the issue of right turn lanes running separately from main road leading to left turn from right turn lane and right turn from left lane being possible with routers.
  Looking at this in ID, the orange 'historic US Highway 66' should be split; the dots in the center are on a divider if I recall when I was there recently. That divider ended as the road turned yellow into what was just titled Frontage Road; no idea if switching the road type and name there as such is correct or not. Once the Highway 66 is split into two different ways going one-way for east and west, the turn lanes connecting should have turn restrictions setup to limit traffic flow to them from the left/right turn lanes accordingly. I presume your recent additions were what should be done if not splitting the road so their logic just needs to be transferred to the split where needed (some segments won't touch anymore so they will disappear).
  I usually use josm instead of id or vespucci for most of my work but see several untagged nodes around the eastern set of curves (near this note). Do they serve any purpose that you can see? They could be moved + given values of signs, streetlamps, etc to reuse without unnecessary node count climbing or just deleted. Having mouse issues which makes me very uncomfortable doing edits here at the moment as clicking and spamclicking that the mouse does could lead to unintentional bad edits.
