Thanks for the heads-up and especially for all the documentation. That video is really helpful.
My first thought is to set the transition from Purchase Pkwy to I-69 at the south end of the Mayfield bypass. I'd rather not introduce a new waypoint at the actual END sign location that will not correspond to a point needed on the extended I-69.
Although I'd prefer to keep the stub of former parkway north of I-24 around, since a lot of people have clinched it, I can't think of anything to call it. Does anyone think it's worth contacting KYTC to see if there's a name/internal number for it, with the idea it could be put in usasf? OTOH, it's less than a mile long, so hardly seems worth it.
