Now, did I miss any?

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.

[froggie]

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.

Now, did I miss any?

I-49: None

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

[Mergingtraffic]

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.

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.

[Duke87]

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.

[Revive 755]

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 (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?

[Alps]

I-99: 999: 1. (renumbering of I-80)

Now, did I miss any?

Fixed.

[froggie]

Wasn't I-124 decommissioned a couple of decades ago?

Nope.  Still active, if not signed.

[golden eagle]

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).

EDIT

I-43 has none, as well as I-4, I-8, and I-24.

Sorry, I missed the above I-4 before I posted.

I-12 should be a I-x10

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.

I-99: 999: 1. (renumbering of I-80)

Fixed.

I see what you did there! :lol:

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