There's an LA Times article about the CA 238 freeway impact: Even freeways that don't get built leave a scar. How one Bay Area city is healing (https://archive.is/z75BW). Also mentions CT 34 and I-710 in passing, but it's much more about the impact than the roads themselves.
The article mentioned a 2021 book published by the Hayward Area Planning Association: The Rise and Fall of Hayward's Route 238 Bypass (https://www.google.com/books/edition/The_Rise_and_Fall_of_Hayward_s_Route_238/HZVOEAAAQBAJ?hl=en&gbpv=0&kptab=overview). About 66 of the 324 pages are up for preview at the Google Books link. Looks interesting, and includes some info of the CA 92 extension proposal (and a rendering of the 92/238 interchange).
Thank you for sharing, it was an interesting article. It looks like some people got very lucky when the state finally decided to start selling off some of these surplus properties.
I remember the ghost ramps that were once present on I-680 between Auto Mall Parkway and Washington Blvd, they fascinated me as a kid when we'd pass by. I was a little sad when they got torn down about 20 years ago when they were adding the express lanes to I-680.
If CA-238 had been built as-planned, it would have been a good alternate route to I-880 via I-580, and may have also taken some of the pressure off of I-880 by the heavy truck traffic. It's also would have been a good potential alternate to I-680 over the Sunol Grade. It's hard for most to justify pushing a freeway through the middle of an existing community, however and I am inclined to agree.
If the CA 238 freeway had been constructed, would it have also become an extension of the "hated" Interstate 238?

Doubtful. The only reason why I-238 has that red white and blue shield instead of the miner's spade is that it serves a significant volume of truck traffic that is required to bypass the section of I-580 through Oakland. CA has several other examples of freeways that exchange interstate designation for state designation of the same number, and I don't see how this would be any different.

If anything having a State Highway continuation would be in line with other routes like 15, 110 and 210.

Don't forget I-710 and CA-710. CA-710 exists at the CA-134/I-210 interchange

CA 710 only exists because the state has to own that stub. I've heard rumblings of it being decommed.

Hence my sense of urgency in grabbing photos recently. Basically it is signed as "To I-210" similar to how CA 259 is signed as "To CA 210."
