I just pulled in several route file updates, in southern California mainly in the area east of Los Angeles and between CA 91 and CA 210. Most of the changes are to streamline the route files and re-synch them with intersecting routes. But some routes have new and/or relabeled endpoints, or major mid-route changes, which will affect list files:
CA 60 and CA 71 -- relabeled endpoints, to fix incorrect or unsigned exit numbers
CA 66 -- state legislature truncated east end to I-215
CA 79 -- reroute between San Jacinto and Beaumont
Both CA 66 and CA 79 also have mid-route segments relinquished to local maintenance (and removed from the legislative route definitions), which I am more reluctant to remove from the route files than end-of-route relinquishments that I can just treat as truncations. Those local governments are required to maintain continuation signage, but such requirements seem to be generally treated as a joke. I would nevertheless keep in the route files the relinquished CA 66 segment, and one of the two relinquished CA 79 segments.
For CA 66, and CA 79 in Temecula, I-15's junctions with the relinquished segments still refer to them as part of their respective state routes. The relinquished segment of CA 66 (roughly between TowAve in Pomona and PepAve in Rialto) has no green-spade CA 66 signage on the route itself, but there is a lot of official and unofficial old US 66 signage to guide travelers, and there are no turns to lead travelers astray. The relinquished parts of CA 79 in Temecula between temporary points TemLim(ELim) and TemLim(NLim), and the implied concurrence with I-15, are also fairly easy to follow, despite the missing continuation signage within Temecula city limits other than on the implied concurrence with I-15.
CA 79 in San Jacinto, between MenAve(SanJacSLim) and End(SanJacOldNLim), is another story. Travelers need to make three turns to follow the relinquished segment to the rest of CA 79, and there is no signage at two of those turns (between Ramona Blvd. and State St., and State St. and Ramona Expy) to guide travelers. I was thoroughly confused when I tried to do that in winter 2016, and only after multiple time-wasting passes through San Jacinto was I able to accidentally clinch the relinquished segment. I would break CA 79 in two in San Jacinto: a main segment from Hemet south to I-8 via Temecula and Julian, and a northern segment between San Jacinto and I-10 in Beaumont, with MenAve(SanJacSLim) => MenAve and End(SanJacOldNLim) => End.
EDIT: Another batch of updates to be pulled in, mainly state freeway routes in Los Angeles and Ventura Counties. One of those routes, CA 2, includes a mid-route relinquishment I haven't figured out how to handle, so I just polished up the rest of the route in the meantime. This is the section from I-405 east via Beverly Hills to the West Hollywood city limit near La Brea Ave.
