NE: Interstate ending exit numbers

[the_spui_ninja]

I recently clinched all the Nebraska interstates, and noticed that Nebraska marks all of its Interstate termini with I-80 exit numbers (e.g. I-76's only exit in NE is 102, I-180 goes 2, 1, 401, etc.). Currently in the HB all of these just end at "I-80". Should this be updated to reflect the situation on the ground?

Verified the '102' for I-76. https://goo.gl/maps/TCXc6dufioukFNxS9
Verified the '401' on I-180. https://goo.gl/maps/8LJhEuUHwXrfQKTDA

I would think we should have those exit numbers in the HB.  Seems weird though, but they are indeed posted.

'446' for I-680: https://goo.gl/maps/kimaQRcD37ZWVpXN8
'452' for I-480: https://www.google.com/maps/@41.2319541,-95.9551588,3a,75y,186.92h,96.24t/data=!3m6!1e1!3m4!1sflbvMhVEfR4TDTsF6cB7OA!2e0!7i13312!8i6656 (it wouldn't shorten that one for whatever reason)

I'd say these fail the "If the highway is a freeway and has a unique exit numbering system based on its own designation without the exit numbers restarting" test.
Seems we're falling down at least as far as "If there is more than one exit number sequence for a highway and no concurrent route to explain it"

I would go without exit numbers on these based on the past I-476 thread: https://forum.travelmapping.net/index.php?topic=2589.0

test.

I don't think that http://cmap.m-plex.com has worked for years.

I think you were going for this.

CHM was what we had at the time I wrote the post.

Are there similar situations in other states regions?

I definitely cannot think of any offhand.

Here's a weird one: AR I-430.
The end was signed as Exit 129 all the way back, formerly just labeled I-30, Nebraska-style.
It already had an Exit 1, and rather than add Exit 0 or get into more alphabet soup for Exit 1 or even 129, ARDOT chose to add Exit 128.
Needing 128(30) now, there's not much justification for keeping I-30 rather than 129(30).

And on the other side of the Little Rock metro, you have I-440 using Exit 138 from I-30 while I-530 uses Exit 1. Additionally, I-630 uses Exit 1 for a ramp that doesn't intersect I-30 while using 139B&C for the ramps that do intersect I-30 (why do you hate Exit 0 Arkansas). It seems like this is Nebraska and Arkansas' way to avoid using Exit 0s (although Arkansas is very inconsistent).
Meanwhile, in Memphis, I-40 starts out with a bunch of suffixed Exit 1s then starts a sequence that continues onto I-240 while I-40 takes over the Sam Cooper Boulevard numbers (here, probably a holdover from when Sam Cooper was supposed to be I-40).

I think overall for these now 6 cases (I-180 NE, I-480 NE, I-680 NE, I-440 AR and I-630 AR), the ##(XX) format seems to fit this to a T, since that's what anyone will see from the road (would avoid the question of "I thought this was Exit 401, why does the HB just say "I-80"?) and it's an exit number sequence from another exit numbered road.

Should this be moved to the "Solved" board since nothing's really changed?
