Edited to clarify: Single-digit routes fall into the zero group.

For example, Indiana has:

US (0)6
US 12
US 20, 24, 27
US 30, 31, 33, 35, 36
US 40, 41
US 50, 52
I-64, I-65, I-69
I-70, I-74
I-80
I-90, I-94

How many other states have this?

I think Maryland has them all except for a 3:

US (0)1
US 11, 13, 15
US 29
- (next closest would be US 30 in Southern Pennsylvania)
US 40
US 50
I-68
I-70
I-81, I-83
I-95, I-97

2 states that miss 1 first digit:

Ohio misses a 1x
US (0)6
[no US or I-1x]
US 20, 21, 22, 23, 24, 25, 27
US 30, 33, 35, 36
US 40, 42
US 50, 52
US 62, 68
I-70, 71, 74, 75, 76, 77
I-80
I-90

Pennsylvania misses a 5x
US (0)1, 6
US 11, 13, 15, 19
US 20, 22
US 30
US 40
[no US or I- 5x]
US 62
I-70, 76, 78, 79
I-80, 81, 83, 84, 86
I-90, 95, 99

Yet, right next door West Virginia has all of them except a "9":

1:  US-11, US-19
2:  US-22
3:  US-30, US-33, US-35
4:  US-40, US-48
5:  US-50, US-52
6:  US-60, I-64
7:  I-70, I-77, I-79
8:  I-81

And yes, neither Maryland nor West Virginia have "0" routes (but those aren't technically 2dI and 2dUS  :hmmm:).

Illinois. In fact, the only gap of greater than six is 80 → 88.

Michigan

0 - US 2, 8
1 - US 10, 12
2 - US 23, 24
3 - US 31
4 - US 41, 45
5 - missing
6 - I-69
7 - I-75
8 - missing
9 - I-94, 96

Alabama is only missing the single digits.

I-10, US 11
I-20, US 29
US 31
US 43, 45
I-59
I-65
US 72, 78
US 80, 82, 84, I-85
US 90, 98

Virginia has them all.

US 1
US 11, 13, 15, 17, 19
US 21, 23, 29
US 33
US 48
US 50
US 60, I-64
I-77
I-81, I-85
I-95

Colorado is missing the ones, sixes, and nines.

0 - US (0)6
1 - missing
2 - US 24, I-25
3 - US 34, US 36
4 - US 40
5 - US 50
6 - missing
7 - I-70, I-76
8 - US 84, US 85, US 87
9 - missing

However, we do have US 160 and US 491. So the only family that we are missing are the ones.

Massachusetts only works on several instances of single-digit. Does this count?

US 1
US 20
US 3
MISSING-4
US 5
US 6
US 7
I-84
Several I-9X

Texas has all first digits:

0: I-2
1: I-10
2: I-20
3: I-30
4: I-40
5: US 59
6: US 69
7: US 79
8: US 80
9: US 90

I intended single digit routes to have an implied first digit of zero. I also excluded state highways.

Tennessee carries quite a number of US Routes, though.

0 - nope
1 - US 11, 19
2 - US 23, 25, I-24, I-26
3 - US 31
4 - US 41, 43, 45, I-40
5 - US 51, 58, I-55
6 - US 61, 64, I-69
7 - US 70, 72, 74, 76, 78, 79, I-75
8 - I-81
9 - ...not north/east/south/west enough

Florida could be only
US 19
US 23 or 27
No US 3 starting for two digits
US 41
No US 5 starting.
No US 6 starting.
I-75
No US 8 starting.
Yeah US 92 and 98.

Two consecutive only

OH, if not mentioned has for zero US 6.  No one routes though, but US 21-25. Then US 30, 33, and 35. Then US 40 and 42 followed by US 50 and 52. None in 6.  I-70, 71, 74,75, 76, and 77.  Then I-80 and last I-90.

Florida, as the OP wanted it:

0: US 1, I-4
1: I-10, US 19, US 19
2: US 23, US 27, US 29
4: US 41
7: I-75
9: I-95, US 90, US 92, US 98

So FL is missing 3, 5, 6, and 8. Not too great.

Georgia does better, missing only 3 and 6:

0: US 1
1: US 11, I-16, US 17, US 19
2: I-20, US 23, I-24, US 25, US 27, US 29
4: US 41
5: I-59
7: I-75, US 76, US 78
8: US 80, US 82, US 84, I-85
9: I-95

- I did Ohio already (2nd reply)
- There's US 62 and US 68 in the state.

North Carolina:

US 1
US 13, 15, 17, 19
US 21, 23, 25, 29, I-26
No 3x (yet…I’m sure they’ll come up with another interstate at some point)
I-40, I-42
US 52
US 64
US 70, 74, 76; I-77
I-85 (I refuse to recognize the other interstate that fits this criterion as a 2di)
I-95

US 50
US 60, I-64

Also 52, 58, I-66

California is missing 2, 3, 6, and 7:

0 — I-5, US 6, I-8
1 — I-10, I-15
2 —
3 —
4 — I-40
5 — US 50
6 —
7 —
8 — I-80
9 — US 95, US 97

10 — US 101 (why not?)


There's two more if you include decommissioned routes:
6 — (Former US 60, US 66)
7 — (Former US 70)

Wisconsin doesn't fare too well in this category.

0 - US-2
1 - US-10
2 - Missing
3 - I-39
4 - I-41
5 - US-51
6 - US-61
7 - Missing
8 - Missing
9 - I-90

Yes, obviously there are other examples in Wisconsin. I just named one for each.

EDIT: Coming in a year and a half later to address an oopsie; I-15, US-95, and who knows what others I'm missing do in fact cover the 5. Yikes, that's a tough miss.

For both Vermont and New Hampshire:

8x: I-89
9x: 2 interstates in both states
1x, 2x, 3x, 4x, 5x, 6x, 7x: doesn't exist in either state.

Louisiana and Mississippi both miss 0's and 3's

Wisconsin doesn't fare too well in this category.

0 - US-2
1 - US-10
2 - Missing
3 - I-39
4 - I-41
5 - US-51
6 - US-61
7 - Missing
8 - Missing
9 - I-90

Yes, obviously there are other examples in Wisconsin. I just named one for each.

0-US2,8
1-US 10,12,14,18 fmr 16 (Thanks Minnesota)
2-None ( Although US 20 does come close)
3-I-39
4-I-41,43,US 41,45
5-US 51,53
6-US 61,63
7-None
8-None
9-I-90,94

Table of states reported by how many they're missing:

0 - Indiana, Illinois, Virginia, Texas
1 - Maryland, Ohio, Pennsylvania, Alabama, North Carolina
2 - West Virginia, Michigan, Tennessee, Georgia, Iowa, New York, Louisiana, Mississippi

2: none
3: none
4: none
5: none
6: none
7: none

Given that Washington was just done, that leaves the following unaccounted for:

Arkansas
Connecticut
Delaware
Kentucky
Oregon
Rhode Island
South Carolina

And I suppose also DC.

3x: none
4x: none
5x: US 50

So missing either 5 or 6.

4: US 41, US 42, US 45

OR
0: I-5
1: none

Interesting that Texas only made it to the top because of recently commissioned interstates, I-2 and I-14. Are there any others that wouldn't have made it as well as the did? North Carolina already had 4, 7, and 8 examples before their new additions.

^ Texas would have had I-10 already to cover part of that…

Indiana and Illinois have been on that list forever, pretty much entirely because of Lake Michigan and a very-out-of-grid US 6. (Now why does that never bother anyone…)

Excuse me, I-95 does indeed count for DC!  So it should move up a step on the table.

I had already accounted for I-95 for DC.
