Counties served from routes emanating from California

[Konza]

Populated my mob-rule.com map with counties served by US and Interstate routes that originate (or at least used to originate) in California.  They appear to reach approximately 797 counties- but that includes 261 counties served by US routes 40, 60, 70, and 80, which, of course, no longer extend west into California, but diverge off of the Interstate routes that took their place in California and at least one state further east.

Once again, the order of priority was Interstate routes, starting with the highest numbered route, then US routes, starting with the lowest numbered route.

In the meantime, I populated the map for Kansas, US and Interstate routes through which reach 770 counties.  This was lower than I expected for "Midway USA", but the vast majority of the routes that emanate from Kansas go pretty much straight north-south or east-west, and even with US 40 and 50, and I-70, they just don't reach that many counties.

The scoreboard, so far:

IL  1273
TX  1160
IN  1148
OH  1089
MO  1005
TN  995
PA  879
CA  797
KS  770

What are the colors supposed to indicate?  Either way, that's a good illustration showing the damage done to the US Route System.

The Key/Legend is to the right. Each color represents a different route, though some overlap.

Ah, it was cut out on my iPhone screen...got it.

42/48. That's pretty good for a coastal state.

[US 89]

42/48. That's pretty good for a coastal state.

I'm seeing 40/48 - missing ND, SD, MN, WI, MI, VT, NH, ME.

39. Also missing SC.

As near as I can figure, there are only five states in the lower 48 where every US or Interstate highway that enters the state terminates there.  Not surprisingly, four of them are in the corners- California, Florida, Maine, and Washington.  Michigan appears to be the other.  Easy to truncate routes that are redundant in your state but are still important a thousand or so miles away.

US 95 enters California but doesn't end there. AFAIK the only US Route to enter a "corner" state not to end there.

Honorable mention: US 31 misses entering Florida by less than 1000 feet.

Especially one that loves to truncate US routes.
