All the exit numbers that we currently have all the way up to 5 need to be reentered. Exit numbering starts @ 2, not 1 since it's exit numbers continue from I-980 mileage.

Any updates on this?

While I'm thinking about it, I'm sure https://postmile.dot.ca.gov/ would be of some help.

I haven't yet used the Postmile Query Tool, but it seems to be a useful supplement to the old 2002 paper route logs, and the more recent online bridge logs (more up-to-date, but less complete, than the paper logs). It might be especially useful for any new or extended state routes, though lately Caltrans has been shedding mileage much more rapidly than adding new mileage.
Next step -- and possibly the main thing to be done before getting the system to "preview" status where users can at least tentatively map their travels -- is getting on top of all the recent partial route relinquishments, and developing an approach to dealing with them that minimizes chopping up routes into little pieces, so we can more or less settle what gets mapped in TM. That is a headache, especially since local jurisdictions that are supposed to maintain continuation signage when they take over relinquished route segments, often don't. Now that my own extensive travels are winding down for this year, I'll have more time to resume work on that.

While I'm thinking on this, I can understand why CA 259 got removed from the project, but if I may argue for its inclusion on the basis it has its own independent exit (Highland Ave), I would.
