I guess I never thought of it before, but I-84 on both sides of the conutry only has one even ended 3di.
I-684
and only 2 odd ended 3di.
I-184 and I-384
Any others that come to mind?
or any that use up all the 3dis including odd and even?
I-90 and I-95 come to mind.
Only one state and 2-digit route uses all the potential 3-digits...that being I-90 in New York. I-95 doesn't.
The two I-86's have exactly zero 3di's...
17 and 19 also have zero, along with the entire state of Arizona!
I-43 has none, as well as I-4, I-8, and I-24.

Well I-84 did have I-284 and I-484 planned but never built...
- Neither of the I-88's have 3di's
- I-97 doesn't have any, but there were planned
- I-99 has none
- I-16 in Georgia only has I-516 in Savannah
- I-89 only has I-189 in Burlington, VT
I-25 only has I-225, the western I-76 doesn't have any, I-27 doesn't have any
I-4 has no 3dis, but it has a terminus with a 3di, I-275.
I-12 has no 3dis, but somewhat interesting that its eastern terminus is with 2 separate 2dis, I-59 and I-10.
I-49 has no 3dis (may change in future).

Sorry, I missed the above I-4 before I posted.
I-68 has none.
I-79 has two (I-279 and I-579).
I believe US 27 in Chattanooga is still unsigned I-124.
If so, I-24 has no signed 3dis and one unsigned 3di.

Grzrd is correct here, at least south of the Tennessee River. The south end of the river bridge is the official terminus.
15 only has 115, 215 and 315, IIRC.
Also, I-8 has no 3di.
Quote15 only has 115, 215 and 315, IIRC.

Yup, remembered Las Vegas just after posting.
I-89 has only one, in Burlington, which is only one mile.
Didn't see I-66 mentioned.
4, 8, 12, 17, 19, 27, 39, 49, 57, 66, 86, 97, 99 all have no 3di. (Posted this off the top of my head, probably wrong about a few.)
I believe I-80 uses all the possible 3di combinations in its run cross-country, albeit not all in one state.
Neither of the I-88s have 3di's.

Updated your list above with the missing ones.
I-72 & I-74 have one 3di each.
I-44 has one signed 3di (I-244 Tulsa), one unsigned 3di (I-444 Tulsa), and one decommissioned 3di (I-244 St. Louis, now I-270).
I-57 is the longest interstate without a 3di.

I'm still not too sure about I-305. It's not signed and (from what I read in another topic) CalTRANS doesn't actually maintain it internally, either. I believe AASHTO recognizes it, though.
The same applies to I-910. It officially exists but is not signed or recognized, and I believe it's due to be wholly engulfed by the future I-49 extension.
I-910 has been approved, but does not exist, as LaDOTD has not followed through.
You missed the unsigned I-444 (OK).
There is no I-191 or I-491. But there is a I-391. There are two instances of I-291.

Since you are including proposed 3dis, Future I-22 will have one 3di, proposed I-422.

Well I-84 did have I-284 and I-484 planned but never built...
Yes sadly, however, I believe if those were built, given the ghost ramps and the left exits/entrances that were planned, it probably would've created more back-ups due to the poor designs of the proposed interchanges.
Part of I-484 was actually built. Take the "Capitol Area" exit off of I-91 (29A). It's horribly substandard, though, and was demoted years ago to an unsigned state highway.
It's been mentioned in some other thread that MoDOT would like to switch the planned routing of I-49 to follow existing MO 249 and avoid multiplexing with I-44. There's the possibility that this will result in a new 3di for the former section of I-49 along US 71 down to I-44.
I-564 has been proposed for the I-64 to relocated I-70 route around East St. Louis: (27 MB file)
http://www.newriverbridge.org/documents/plans/J6U1086%20plans/AJR/Appendix%20C%20Figures%2001%20to%2020.pdf (http://www.newriverbridge.org/documents/plans/J6U1086%20plans/AJR/Appendix%20C%20Figures%2001%20to%2020.pdf) (See page 21/21)
I would expect to see one of the Kentucky parkways become a 3di after I-69 is officially signed in that state - I'd bet on the Audobon, being the shortest and probably cheapest to upgrade next.
If one wants get into the speculative, I-57 and western I-88 could get 3di's for the Illinana and Prairie Parkway corridors respectively.
Wasn't I-124 decommissioned a couple of decades ago?

I really wouldn't disagree with that. To tell you the truth, I think a 2di should have to cross between two states to be called an interstate. 4, 17 & 19, among others, would fall under that too.

Indeed, the Audubon is signed as "Future Spur I-69."
