^ Right now, I'm focused on getting canqc ready to activate (likely by the end of the month), before turning my attention to usaca.
Those Lim labels indeed reflect relinquishments that have already occurred. I think the one in Temecula should be ignored, since the original route is easy to follow, and there's signage for the relinquished segment on I-15. The one in San Jacinto will likely warrant a route split, since you have to take several unsigned turns to follow the original route, and I got thoroughly lost when trying to clinch the route there several years ago. That's similar to the situation in Sacramento with CA 160, though an End 160 sign at the south end of the relinquishment sealed the deal for me, so I made that route split already.
I need to catch up on possible plans for CA 79 to be completely rerouted to avoid the mess in San Jacinto.
EDIT: There is indeed a plan, which has cleared environmental approvals, that would have CA 79 bypass the downtowns of both San Jacinto and Hemet, and also might reroute part of CA 74. However, the plan remains stalled in the pre-construction phase pending funding for the non-local half of project costs.
