Half access is always enough to add a graph connection.
Generally, yes. Notwithstanding obvious exceptions like trumpets etc. of course.
I believe the strictest interpretation of the manual would have one point on I-15, midway between D St & NV578, and another point in the NV578 centered on the roadway itself, so no graph connection. That said though, A lot of people seem to be moving away from this in favor of having a graph connection, and putting a point "off-center" on one route if there's another route in the HB, at junctions like this one. Which makes sense, really. Maybe it's time to update the manual, mumble mumble...
[edit] Are you suggesting putting graph connections at both interchanges,
If by "both" you mean the I-15/US95 junction and Exit 44, sure...
but breaking the overlap in between? WTF?
If it were my state to maintain, maybe, sure, yeah. (Though I did
concede above that I can see the logic in not doing so as well. NV is Oscar's state to maintain as he sees fit, and so I can't & won't fight it all the way to the end of the Earth.)
I-15 & US93 are clearly carried on different physical roadways here.
For similar examples in my states to this idea, point mapview at
Providence, 95/195 jct
or a more mind-bending example & possibly my personal favorite, Fall River, @ US6, MA79 & MA138.
