Something that I've had in my head, but never seen here: When travelling north on US-23 in Washtenaw County, Michigan, you encounter in four consecutive exits: US-12, I-94, M-17, Business US-23 & Business I-94. What examples can you find of consecutive exits that carry signed highways, but all a different level? Michigan doesn't have many county numbered roads, so it's possible there are others that are more.
First one I can think of I-65 south of Birmingham features:
Exit 246 - AL 119
Exit 247 - CR 17
Exit 250 - Interstate 459
Exit 252 - US 11
The next exit for Alford Avenue isn't signed with a shield at all, but I don't know if it's county-maintained or not.
West Virginia has to have at least one consecutive set with five levels, and probably Texas as well...?
If you ignore certain legs of the interchanges, I-64 in Chesapeake, VA going eastbound (cardinal direction west)...
Exit 290(B) - VA-168 Business (also VA-168 North)
Exit 291(B) - VA-168 (also I-464 and US-17)
Exit 296(B) - US-17 Business (also US-17 North)
Exit 297 - US-13 / US-460
Exit 299 - I-264 / I-664 (also US-58 / US-460 / US-13)
I-70 in Maryland comes very close:
Exit 42 - MD 17
Exit 48 - US 40
Exit 49 - Alt US 40
Exit 52 - US 15/340
Exit 53 - I-270
I-75 in Michigan has
Exit 162 - US-10 and M-25 which both terminate at that exit coming from opposite directions. M-25 also carries BS-I-75 into downtown Bay City before BS-I-75 just turns around and goes back to I-75.
Exit 160 - M-84
Exit 155 - I-675
The Capital Beltway in Virginia from the general-purpose lanes:
Exit 52 for VA-236 (state primary route)
Exit 51 for VA-650 (state secondary route)
Exit 50 for US-50
Exit 49 for I-66
On US 31 near South Bend, there are consecutive exits for IN 2, US 20, I-80/90, and BUS US 31.
If Indiana signed county highways like other states, the Mayflower Rd exit just south of the IN 2 exit would be a 5th different level.
Along I-90 in MA:
Exit 4: I-91/US 5 (originally, this interchange connected to just US 5)
Exit 5: MA 33
Exit 6: I-291/US 20 (correction: US 20 meets I-291 further south at Page Blvd.)
Further east:
Exit 10: I-290/395/MA 12
Exit 10A: US 20/MA 146
Exit 11: MA 122
Along I-95 in southern MA:
Exit 1: US 1 (partial interchange)
Exit 2: MA 1A (RI used to sign its stretch just south of the interchange as US 1A)
Exit 3: MA 123
Exit 4: I-295

Best I can do is four. AFAIK, there is no HARP road signed as an exit. Or are you counting "fractionals" ?
I-79
Exit 0 - I-77
Exit 1 - US 119
Exit 5 - WV 114
Exit 9 - CR 43
If fractionals count, then
I-79
Exit 146 - CR 77
Exit 148 - I-68
Exit 152 - US 19
Exit 153 - CR 46/7
Exit 155 - WV 7

What about the Nimitz Parkway interchange that comes right before I-80/90?

I-79
Exit 0 - I-77
Exit 1 - US 119
Exit 5 - WV 114
Exit 9 - CR 43
That was the one that immediately came to my mind, but when signs were replaced at Exit 5 a few years ago, WV 114 was removed from the signage and replaced with US 119. I contacted WVDOT to ask why, but my inquiries were never answered. The only thing I can figure out was that it's a situation similar to how US 19 is not signed on southbound exits between Morgantown and Sutton, so people won't exit looking for Corridor L. They don't want people taking that WV 114 exit to get to the airport.

I forgot that they are separate interchanges NB. SB they are part of the same interchange so it still works that way.
I-295 Southbound in NJ:
Exit 31 - Train Station Parking lot (Municipal or authority jurisdiction roadway)
Exit 30 - County Route 669 (Warwick Rd)
Exit 29 - US 30
Exit 28 - NJ 168
Exit 26 - I-76
I-295 Northbound in NJ works as well in the same vicinity, yet has different exits! (Also need to consider Exit 29A/B as a single exit)
Exit 27 - I-76
Exit 28 - NJ 168
Exit 29A/B - US 30
Exit 31 - Train Station Parking Lot (Municipal or authority jurisdiction roadway)
Exit 32 - County Route 561
Business loops, alternate routes, etc........ These feel a little like cheating to me. I think, in order to "really" make it to five, we would need a state that has secondary state highways and also signs its county highways. Then we could have Interstate, US Route, Primary State Route, Secondary State Route, County Highway.
MA Route 24:
Exit 14 - I-495
Exit 13 - US 44
Exit 12 - MA 140
I-294 North
Exit-27: US-34
Exit-29: I-88
Exit-30: IL-38
Interstate 380 in San Bruno fulfills this:
Exit 5A/5B - I-280
Exit 5 - Route 82/El Camino Real
Exit 6 - US 101

Minor correction. Exit 6 on the Mass Pike connects only to I-291. The I-291/US 20 overlap begins at Page Boulevard, and not the Turnpike.
I-90 New York:
Exit 35 NY 298
Exit 36 I-81
Exit 37 Electronics Pkwy
(CR 148, but not signed as such)
Exit 38 CR 57

4-level examples in Iowa:
I-80 in the Quad City area:
Exit 284 - County Rd Y40
Exit 290 - I-280
Exit 292 - IA 130
Exit 295 - US 61
I-35 near Ames:
Exit 102 - IA 210
Exit 111 - US 30
Exit 113 - Business I-35
Exit 116 - County Rd E29
I-35 near Mason City/Clear Lake, depending on how overlaps are handled:
Exit 193 - Business I-35
Exit 194 - US 18 west
Exit 197 - County Rd B20
Exit 203 - IA 9
Given the quality of the county road signage in Iowa, I'm sure there are numerous other US/IA/CR combinations.
The only one that immediately comes to mind for Utah is this one on I-80:
Exit 123B - I-15 south
Exit 124 - US 89
Exit 125 - SR 71
Exit 126 - 1300 East (unsigned FA 2076 - sort of a secondary route system)
This one spans Wisconsin and Illinois on I-39/90.
Illinois Exit 8; IL-173
Illinois Exit 3; Winnebago County 9 (Rockton Road)
Illinois Exit 1; US-51
Wisconsin Exit 185; I-43 (WI-81 is there too, so state routes from two different states is a bonus :spin:)
Best I have for Missouri so far are a few three's:
I-270
* I-64/US 40/US 61
* Route AB
* MO 340
I-229 SB
* MO 371
* Route A
* I-29
I-29
* Route K/Route CC
* I-229 SB
* US 71 NB (technically it's a separate exit but at the same interchange as I-229)
More Missouri examples:
I-270 -> MO 366 (same interchange as I-270, different exit) -> US-50/67 on I-44.
All classes appear consecutively on James River Freeway, but not necessarily in order of class: US 160 -> MO 413 -> Supplemental/County MM -> I-44.
The two Minneapolis examples cheat to varying degrees, and both are on I-694
41AB: I-35W
42A (EB only): MN 51
42B (WB only): US 10 westbound
43A: County 51 (unsigned from the freeway)
47: I-35E northbound
48: US 61
50: County 65 (unsigned from freeway)
51: MN 120
I guess there's another but it's also arguable
I-35 in Forest Lake
132: US 8 (NB only)
131: County 2
129: MN 97
127: I-35W/E split

Except the MO 413 interchange is shared with US 60 (https://goo.gl/maps/DarSNZ7KfP8iPDxm9)
Otherwise there could be another 4 on I-57: I-55, Route B, MO 105 (shared with BL 57), US 60/US 62 (shared with MO 77 and BL 57).
I-20 in Louisiana
Exit 26: I-220
Exit 33: LA-157
Exit 38: Parish Road 117 (Goodwill Rd)
Exit 44: US 371 North
In terms of signage, there's a possibility on I-275: KY 212, Mineola Pike, I-71/75, and US 25/42/127. However, Mineola Pike has a 3000-series state route designation that's not included on the signage.
If you want to cross state lines, you have TO KY 8 (formerly KY 8, now a four-digit route), US 50, Kilby Road, and I-74 on I-275.

Exit 60: US 6/44

Both good ones!
I'm going to add a stretch of I-86:
Exit 32 CR 2
Exit 33 TO NY 21
Exit 34 NY 36
Exit 35 Howard (no route)
Exit 36 I-390
So that's five, but I added two questionable categories: TO a route, and NO ROUTE.
But I also didn't even use a US route, which is something not many others have done.
Is that legit? :-P

Exit 33 is actually for a state reference route, so it does connect to a state highway, just not the one signed with the TO banner. Exit 35 is for a county route, though that's not signed from the guide signs, but Steuben County does sign its county routes.
