So it appears there is a bit of a mixed message on the wiki between what you suggested and what I did (name= page explicitly says what is on the street sign). I think either way works; the data is there at least, so navigation software can use it. I'm inclined toward my method (which was unsigned_NAME, not unsigned_ref; I mistyped above) a bit more solely because I don't want to mislead someone into looking for a N 56th St sign (or N 56Th St, as Lancaster County is fond of doing...) that doesn't exist.

Every time I drive it (and most recently was last Sunday), I check to see if the county has put up signs. Still nothing. I'm quite surprised because Lancaster County is usually pretty good about posting some sort of signage (even if they have some weird habits). Maybe the Google Data Center being built will give them a good kick in the pants to get moving? (Although that will probably become Lincoln's problem.)
