Interstates that have children in all of its states

[roadman65]

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 

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.

I-71 (thanks to I-471 being multi-state)

[cpzilliacus]

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.

Pretty sure we've exhausted the list (not counting any intrastate).

I-5
I-35
I-71
I-75

Close misses:
I-15 - Missing ID
I-20 - Missing AL
I-65 - Missing TN

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.

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. 

[SkyPesos]

I-80:
CA: 280, 380, 580, 680, 780, 880, 980
NV: 580
UT: None
WY: 180 
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?

And then I-40, starting from the east coast does really well, not missing any states, and then it all comes to a screeching halt once it hits the Texas border.

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".

(Now if you were to introduce 4di and have them be children of 3di???  whispering so FritzOwl doesn't hear me and get any ideas)

I-195 is off I-295 in NJ.

I-195 is off I-295 in NJ.

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'm a little surprised you missed the one right in your backyard (I-235 off I-135 in Wichita)

[Roadgeekteen]

I-87 has a child interstate in all of its states plus more. Same with I-35.

But I-235 doesn't enter multiple states.

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.

You're right.  I had just skimmed the first posts in the thread and someone had said I-30 was accurate.  I edited my post.

That was my mistake; oops.  I think I was misremembering the Texarkana Loop, which isn't currently an x30 in either state.

What would that be a child of?
