74 -> 74A
Caltrans' official CA 60 exit list says that the 74A exit number is a signage error, should be changed to 74. That's why I used 74 when I updated the route file while getting usaca ready to activate. The exit list was prepared in 2020. Caltrans can be sloppy about keeping its exit lists up to date (like not adding the new exit 22, which I agree needs to be added to the CA 60 route file), and maybe the staff maintaining the signs never got the memo. Or they might've felt that since there is no other CA 60 exit signed as 74, 74B, etc., 74A rather than 74 is "a difference that makes no difference is no difference" (an aphorism used on Star Trek, but predating the TV series) that can be ignored.
