I can repoint CA I-8BLYum (including the border point), synch it with the BL on the Arizona side, and fix the historic route on both sides while I'm at it. I'm still on the road for two more days, but can take care of this from home this weekend.
There may also be a few NMPs at other CA/AZ border points, and maybe some NV/AZ border points as well, as well as many CA/NV border points. Those all are on my to-do list, along with taking care of broken concurrencies and other loose ends from the I-580 extension in Carson City.
There's a general issue with broken concurrencies involving historic routes in CA, since they were drafted just before I did a comprehensive overhaul of active routes in CA to prepare for overhauling the usaca routes. Now that the active and usaca routes in CA have been redone (except for remaining issues re: relinquishments), the historic routes can be resynched to them.
