Interstates that have children in all of its states

[ethanhopkin14]

I think I-90 is irresponsible in Buffalo.  I-990 isn't strong enough to live on it's own and I-90 left I-290 in charge.  I-290 is hardly a qualified babysitter. 

Really?  I-290 is nearly twenty years older than I-990.

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)?

[ethanhopkin14]

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-238 IS JESUS!!!!!

^ 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) 
- 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)

I don't think "divine conception" and "conversion" are the same thing...

And I-H1; I mentioned it upthread.

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.

[ethanhopkin14]

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.

If a turnpike has two legs, you can just check between them.

I-238 IS JESUS!!!!!

A name undoubtedly taken in vain, probably on a daily basis, by commuters trying to get on to it -- particularly from I-880 -- anytime from 3 pm to about 7 pm!

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.
