I-5 is one to come to mind that transits three states and all three states have child routes of the said interstate.
I-75 is another as all states from FL to MI is another one that has a designated child in each state.
I-65 used to until I-265 got axed in Nashville so no more offsprings in TN.
I believe it's it for now until I can research more on it.
I-35 does have at least one in each state.
TX- 635
OK- 235
KS- 135, 235, 335
KS/MO- 435, 635
IA- 235
MN/WI- 535
I-30 (TX, AR)
I-87 (NY, NC)
I-45 :bigass:
May not be around for much longer though, if urbanists and RE/T groups get their way.
I-16 (516) and I-96 (196, 296, 496, 696) qualify, I guess. :P
I-71 (thanks to I-471 being multi-state)
I-95 has child routes in most of the states it crosses:
Florida
not Georgia
not South Carolina
North Carolina
Virginia
DC
Maryland
Delaware
Pennsylvania
New Jersey
New York
Connecticut
Rhode Island
Massachusetts
not New Hampshire
Maine

I-75 have children in more states than itself goes through due to Cincinnati's I-275 going into Indiana.

Are there any 3di that have children of their own? Do any of those enter multiple states? Do any of those have children in both states?

3di's don't technically have children; they babysit siblings. :D
There're a lot of sibling routes branching off the 3di's that don't connect back to their parent. I-278 (NY) crosses to NJ, but none of that complex connects back to I-78.
I-80:
CA: 280, 380, 580, 680, 780, 880, 980
NV: 580
UT: None
WY: 180 :bigass:
NE: 480, 680
IA: 280, 380, 480, 680, 880
IL: 180, 280
IN: None
OH: 280, 480, 680
PA: 180, 380
NJ: 280
For a transcon interstate, pretty impressive that I-80 lacks 3di in only 2 states it goes through.

OK, so it looks like I-278's children/siblings are both in New York, none in New Jersey.
Any others to take a look at?

Another example could be I-795 in Maryland, which does not connect to I-95, only to I-695. It's contained within Maryland however.
If some posters had their way and renumbered I-97 to I-995, that would be another example.
I don't think they're technically children of each other, as another poster said, "one sibling baby-sitting another".

But I-495 is a true child of I-95. Thus, I can't consider it a child of I-295. That leaves I-295 with only one child, and thus it is disqualified, by virtue of my third question.

I am lost on I-30. Texas doesn't have an I-X30 on account of Texas being allergic to 3dis. Not New Mexico or Arizona level allergic...more like they have to take an epipen when they see a 3di, instead of going straight to the hospital.

It may have come from the eastern quadrant of the Texarkana loop being approved as I-130, but only on the Arkansas side. Texas did not comply (buttholes). Now that section of highway is not I-49 so it did technically become I-130 but was never signed.

Same with I-76. Starts out in the east with 676 pretty much right away, then is on a roll in PA with every first digit from 1-6 used, then comes to a screeching halt in OH, NE and CO.
I'll expand jayhawkco's list here...
3di in more states than parent goes through:
- I-35 (7/6, including WI)
- I-38 (1/0, including CA) :bigass:
- I-75 (7/6, including IN)
- I-87 (3/2, including NJ)
3di in same number of states parent goes through, but no 3di in one of the states parent goes through:
- I-29 (4/4, including IA, missing ND)
3di in all and same number of states parent goes through:
- I-5 (3/3)
- I-45 (1/1)
- I-71 (2/2)
- I-96 (1/1)
3di in at least 70% of states parent goes through:
- I-20 (5/6, 83%, missing AL)
- I-65 (3/4, 75%, missing TN)
- I-69 (5/6, 83%, missing MI)
- I-70 (7/10, 70%, missing UT, IN and PA)
- I-80 (9/11, 82%, missing UT and IN)
- I-94 (5/7, 71%, missing MT and IN)
- I-95 (13/16, 81%, missing GA, SC and NH)
2di with same or more 3dis as numbered of states passed through, and didn't make the above lists:
- I-10 (13/8)
- I-15 (6/6)
- I-64 (6/6)
- I-76 (5/5)
- I-79 (2/2)
- I-85 (9/5)
- I-90 (15/13)

My first guess is I-25 (just one child in three states and 1,065 miles)
^ I-59 hits 4 states but has child routes in just one of them...granted, it has 3 child routes in that one state.

And all children happen during the I-59/I-20 concurrency. You could argue that those children are step children (being just as easily numberd I-X20).

Granted I-74 barely enters IA and OH, I-24 barely enters GA, and I-59 (mentioned above) barely enters LA and GA.
Though this doesn't seem like a problem for some other interstates. Like I-64 have a "state route 3di" in a state it goes through for only 40 miles. And of course, I-78 in NY.

Another example could be I-795 in Maryland, which does not connect to I-95, only to I-695. It's contained within Maryland however.
Another Maryland example is I-370, a spur of of I-270 and rather far from the I-70 parent.

Yes. 280 and 980 doesn't directly connect to I-80. Though 280 gets pretty close by in SF, and you could theoretically extend 80 south 2.3 miles on US 101 to end at and meet 280.

Granted I-74 barely enters IA and OH, I-24 barely enters GA, and I-59 (mentioned above) barely enters LA and GA.
But, in those barely visited states, at least the interstates are in metro areas that actually require 3dis, just not from those 2dis. It's not an I-82 in Oregon situation.

I-78 is the second most irresponsible parent interstate. First is I-38.
I posted these two in another 3di thread, but thought it may add to the conversation here:
Quote from: SkyPesos on February 12, 2021, 11:50:04 PM
Since this seems to be the general thread about 3 digit interstates now, here's something I have made up: the 3di frequency rate. Find a 2di route, and count every 3di occurrence of its own. Duplicated numbers will be counted separately from each other. Take the final total, and divide it from its parent route's length. This will give you what I call the "3di frequency rate". A number of 0 means that the 2di has no 3di. Besides 0s, let's see which 2di has the lowest 3di frequency rate, and which has the highest.
Example for I-75:
Length: 1786.47 mi
3di of I-75: I-175, I-275 x4, I-375 x2, I-475 x3, I-575, I-675 x3 = 14
1786.47/14 = 127.605 mi/3di
For the highest, I imagine I-25 would be the winner
For the lowest, some candidates I have in mind just from a glimpse are I-76 Eastern, I-78, I-85, I-91 and I-95. Someone else can feel free to calculate the number for them.
Quote from: SkyPesos on June 13, 2021, 11:37:02 AM
I made a spreadsheet (https://docs.google.com/spreadsheets/d/1N68cWsgFSo14bsXzUOJpnpWcBlnPo622pRx2dhCLTso/edit?usp=sharing) with the number of signed current 3di today, here's some interesting facts I gathered from that spreadsheet:
- 40 2di numbers have a signed 3di. If including unsigned, the number goes up to 42, adding in I-24 and I-45.
- This shouldn't come as a surprise, but I-95 have the most signed 3di variants, at 30 of them, with I-80 (22), I-90 (15), I-75 (14), I-40 (13) and I-10 (13) behind it, as the 5 highest.
- The most used 3di first digit and with the most 3di variants are the I-2xx, with 29 of the 40 2di with an I-2xx, and 61 I-2xx variants.
- As expected, the I-1xx are the most used odd 3di first digit. For second place, 3xx have more total variants, but more 2di have a 5xx.

I-78 is a better parent because it is at least somewhat around while it's children run amuck in the big city? You are saying that's better then I-38 not even being there at all? :-D

Any adult who hangs out in Buffalo is a problem IMO.

Are there any 3di that have children of their own? Do any of those enter multiple states? Do any of those have children in both states?
just a shot in the dark... the *80's in the bay area? seems like some of them might just connect to each other...
Yes. 280 and 980 doesn't directly connect to I-80. Though 280 gets pretty close by in SF, and you could theoretically extend 80 south 2.3 miles on US 101 to end at and meet 280.
980 is pretty close to 80 too (by about 2 miles!).
280 has one child route that is pretty far from 80: the I-380 spur to San Francisco International Airport.

Unless these spurs and loops are grown up and providing for themselves, these are some very irresponsible parent interstates.
I-78 is the second most irresponsible parent interstate. First is I-38.

Does I-270 Spur count? It only goes through one state though.

I'll ask the same about I-480N. Or is that more like a suffixed route (or in I-270 Spur's case, a bannered route)?
Are unsigned 3dis like illegitimate children or children a married man has with his mistress? The parents know whos child it is, but no one else knows because they want to keep it a secret? Think about it.

OK, guys. I know that the answer to the first question is "yes", no need to give examples that only satisfy that qualification. I wasn't sure if any of them enter multiple states, so I appreciate seeing the examples of multi-state child-of-child Interstates. The
real question is whether any of
those has children in both of the states it enters.

^ I-59 hits 4 states but has child routes in just one of them...granted, it has 3 child routes in that one state.
And all children happen during the I-59/I-20 concurrency. You could argue that those children are step children (being just as easily numberd I-X20).
I-759 does not. I-459 only hits the multiplex one of two times.
I think the full list meeting the original criterion is: I-H1, I-5, I-16, I-35, I-71, I-75, I-87, I-96. Is that correct?
Honorable mentions go to I-82 and I-72 for having 3dis in all states where the route spends an appreciable amount of time, but minuscule mileage in another state where there's no associated 3di.
^ I forgot about I-16...

I'll expand jayhawkco's list here...
3di in more states than parent goes through:
- I-35 (7/6, including WI)
- I-38 (1/0, including CA) :bigass:
- I-75 (7/6, including IN)
- I-87 (3/2, including NJ)
3di in same number of states parent goes through, but no 3di in one of the states parent goes through:
- I-29 (4/4, including IA, missing ND)
3di in all and same number of states parent goes through:
- I-5 (3/3)
- I-16 (1/1)
- I-45 (1/1)
- I-71 (2/2)
- I-96 (1/1)
3di in at least 70% of states parent goes through:
- I-20 (5/6, 83%, missing AL)
- I-65 (3/4, 75%, missing TN)
- I-69 (5/6, 83%, missing MI)
- I-70 (7/10, 70%, missing UT, IN and PA)
- I-80 (9/11, 82%, missing UT and IN)
- I-94 (5/7, 71%, missing MT and IN)
- I-95 (13/16, 81%, missing GA, SC and NH)
2di with same or more 3dis as numbered of states passed through, and didn't make the above lists:
- I-10 (13/8)
- I-15 (6/6)
- I-64 (6/6)
- I-76 (5/5)
- I-79 (2/2)
- I-85 (9/5)
- I-90 (15/13)

Speaking of I-16 and I-516, it seems like that a lot of the 2di with only one odd first digit 3di, it's a 5xx. Some other examples 520, 530, 579, and 564 (though I-64 does have a former I-164 and a state route 3di 364). Also I-40 have two 540 variants, while not having a 340 at all. Though a glaring exception to the seemingly 5xx preference is I-70, as I-570 doesn't exist.
Do we call interstates with no children bachelors or bachelorettes?

Depends on their gender. I imagine even interstates as male and odd interstates as female.

I think the opposite. Even interstates are long and go through so many different geological features across the continent. I think of them as long and elegant like a woman. Odd interstates connect north and south, in the east that means industrial area to industrial area. Rugged and oafish, like men.

There are many exceptions of course. I-182 is another.
