Most relevant to the active usaib and usausb systems, but also affecting some usaca routes: I've noticed that some of the on-freeway business route signage I remember in northern California seems to have been removed. This may be a district-by-district thing, mainly in Caltrans districts 1 and 2, but maybe also part of district 3 (signage for I-5BL Woodland seems to still be there, at least on I-5 SB). The ones I have in mind are the I-5BLs in Red Bluff, Dunsmuir, Weed, and Yreka, and the US 101 business routes in Ukiah, Rio Dell, and McKinleyville, though there might be others with removed signage I didn't notice.
Some of the GMSV imagery is about a decade old, and so is pretty useless. But I'll be flying back to Sacramento next week to resume my mega-cross country road trip. This half of the trip will be more relaxed than the first part, so I'll have time to do more complete field checks of business routes (as well as of other usaca routes) to try to nail this down.
Also, as I go through files for revisions, one change I'll be making throughout will be to relabel numbered/lettered county roads. The major ones are called "County Highways" (per a state law authorizing county highway systems), signed with blue pentagon shields. Most of them have labels beginning with CH. Then there are lesser county roads, which usually have no route markers and are signed on street blades or otherwise as "Road ___". Many of them have labels starting with CR (as do a few CHs which I relabeled in error). As I come across them, I'll be changing CR___ labels, generally to either Rd___ or CH____.
I'll be doing fixes on a few usaca routes (mainly to fix NMPs/broken concurrences and otherwise finalize), so far including CA 12, CA 16, CA 32, CA 36, CA 44, CA 72 (west end truncated to Pico Rivera eastern city limit), CA 113, CA 116, CA 121, CA 169 (Weitchpec segment -- an long and unpleasant one-lane highway I clinched last week), CA 188, CA 211, CA 254, CA 255, and CA 299, before I return to California. Much work will remain to be done after my return home, and the eye surgery and recovery to follow.
The routes that were already finalized include at least: 1, 3 (pending addition of waypoint to concurrence with CA 299 in Weaverville), 4, 7, 9, 11, 13, 14, 17, 18, 20, 24, 35, 41, 46, 47, 49 (with pending CR label fixes), 58, 62, 70, 74, 78, 79, 86, 88 (with pending label fix), 89 (both segments), 99 and its business routes, 111 (both segments), 115, 120 (both segments), 138, 140, 144, 154, 158. 165, 166, 167, 168 (both segments), 170, 173 (both segments), 177, 178 (Shoshone segment), 180 (both segments), 182, 190 (both segments), 202, 203, 207, 227, 236, 237, 253, 266, 270, 330, and 905. Some label fixes and other updates may be needed. But for the most part their waypoint coordinates are settled, and I'll use coordinates from those routes and the long-finalized Interstate and US main and business routes to update the remaining state routes and synch them up with already-finalized routes.
