State routes entirely Multiplexed

[agentsteel53]

my 1965 map shows UT-99 heading north out of Delta.  was this ever connected to the Fillmore area, or are they two completely different uses of the same number?

According to Wikipedia (and Dan Stober's defunct site), UT-99 was assigned to a road connecting the Topaz War Relocation Center to Delta, from the 1930s to 1969. This iteration was assigned in 1969, coinciding with I-15's construction through the area. So, I would probably guess not.

thanks for the info!  I drove what I believe is old 99 and there are some older green signs present, but I don't know if they are so old that they date back to before 1969.

I think Iowa 27 is since it's meant to be avenue of the saints

The south end of IA-27 is an independent route from U.S. 218 to the Iowa-Missouri border. It used to have a different designation (394?).

I believe in California, US-70 ran concurrently with US-60 and/or US-99 for its entire length.

while we're at it, I believe every US route in Georgia (and possibly Alabama as well) has a state number as well.  sometimes these diverge (GA-25 follows most of current US-17, but some of old US-17 as well) but I think some are entirely underneath current US routes.

the only example I could find offhand is GA-7 is entirely under US-41 and US-341.

Tennessee is the same way. All interstates have a secret state number

All designated US highways have a secret state number in Tennessee, however, the interstates do not.  Are you saying that they do?  If so what are they?

Yes, US 70 was never on its own in California. US 466 was also cosigned with another US route (US 93 and US 91) in Arizona and Nevada, respectively.

US-466 went up 91 and down 93 in the Vegas area?  there was never an independent routing?

Correct. It wasn't until Barstow that US 466 was finally on its own. It really should have started in Barstow, though would have been briefly cosigned with US 91 across the ATSF Barstow yard.

or it could have been US-291 or something.  I forget how the number parities work for branch US routes that run perpendicular to their parents, so I'm using US-299 as a reference.

I'll see if I can find it. It seems looking at Tennessee state maps that interstates were numbered. I want to say I-75 was TN 2. I'll look when I get home from work. I could be mistaken

IIRC, until the 4xx numbers came into being, the original run of 3-digit US routes were numbered in order of creation, with no factoring in of direction or returning to parent route at all.

that makes sense for why the x60 branches are so oddly located.

160 - 1930
260 - 1932
360 - 1933
460 - 1934

I think for simultaneous creations, there was an ordering from north to south, or from east to west.  at least, this fits with the x01s, x99s, x66es, etc.  (the first 466 slotted in logically between 366 and 566)
