Hierarchy of state routes in your state?

Ma 28 is most important in mass.

Ma 28 is most important in mass.

MA 28 is not a freeway/expressway for most of its length, unlike MA 2, MA 3, MA 24, MA 128, and several others.

oops, forgot about the freeways. New one is Ma 2.

99 by a country mile in Califronia.  58 is pretty high up there as well.

I agree. I would also add

CA 14
CA 60
CA 91

Of course all of those were former US highway corridors showing their importance.

CA 60 should still be a US Route IMO.  The problem is that CA 62 was finished well after the 1964 state highway renumbering which essentially made realignment close to impossible.

Illinois:

This is a bit tough due to what some of the route do, and where they go (and that interstates and US highways already use many of the most important routes), thus I'll list the top routes here:
IL-390 - Elgin O'Hare Tollway (nee Expressway)
IL-53
IL-83
IL-59
IL-38
IL-47
IL-13
IL-3
(And I'm sure, many more)

The least important routes seem to be:
IL-251 - why, oh why?  All it does is parallel I-39/US-51, and very closely at that.
IL-115 - you can go for miles without seeing another vehicle south/west of Herscher.
IL-114 - not very long, and becomes IN-10.
IL-119 - again, not long, and connects to an Indiana state route.
IL-250 - parallels US-50, and not completely.
IL-155 - goes to a state historic site.
IL-135 - what, exactly, does this even do?

No love for IL 1, ehh? Part of the old Dixie Highway? And even South of the Dixie Highway segment, IL 1 goes almost the length of the entire state North to South -- even if it is a not distant parallel to US 41 over in IN

I would throw some love to IL 5 and IL 92 over in the Quad Cities...John Deere is a major employer in the area and state, and IL 5 is the John Deere Highway. I might also say the same for IL 40 and IL 8 in Peoria, Cat's home. IL 4 in Springfield is a pretty major road

For the worthless list -- you forgot IL 110. It really doesn't need to exist...

I'd add IL-64 to that list.
This is difficult to do, when certain segments of a route will be far more important than other segments of the same route.  For example, in southern Illinois, IL-13 is very important east of Murphysboro, but IL-13 is pretty negligible in much of St. Clair County.

OK, rather than try and parse every last highway in California, I'm starting by putting them in groups. Thoughts/opinions/corrections welcome - I'm sure I missed some.

GROUP 1: Statewide (or even national) importance
1, 14, 20, 41, 46, 58, 99, 120, 152, 299

GROUP 2: Regional importance or significant urban routes (often freeways)
2, 3, 4, 12, 16, 17, 18, 22, 24, 36, 38, 49, 52, 54, 55, 57, 60, 65, 70, 71, 73, 76, 78, 79, 85, 87, 89, 91, 96, 108, 111, 118, 125, 126, 134, 140, 180

GROUP 3a: Secondary urban or local routes (including shorter freeways)
9, 13, 23, 27, 37, 51, 56, 67, 68, 82, 84, 92, 121, 133, 156, 163, 170, 237, 238, 241, 242, 261, 262, 267

GROUP 3b: Secondary rural routes (often shorter routes connecting longer routes listed above)
11, 25, 26, 28, 29, 32, 33, 43, 44, 45, 74, 86, 88, 94, 98, 104, 113, 115, 116, 119, 127, 128, 132, 138, 139, 145, 154, 155, 162, 165, 166, 168, 173, 178, 190, 198, 247, 330

GROUP 4a: Tertiary urban or local routes (often former surface routings of upgraded routes, often piecemeal relinquished routes)
19, 34, 35, 39, 47, 61, 66, 72, 75, 77, 83, 90, 103, 107, 109, 112, 114, 123, 129, 130, 131, 142, 144, 160, 164, 185, 187, 192, 204, 213, 217, 218, 232, 255, 263, 265, 273

GROUP 4b: Tertiary rural routes (often very short routes to connect to towns/parks/etc.)
7, 53, 59, 62, 63, 124, 135, 136, 137, 146, 147, 149, 150, 151, 153, 158, 161, 167, 169, 172, 174, 175, 177, 182, 183, 184, 186, 188, 189, 191, 193, 197, 200, 201, 202, 203, 207, 211, 216, 219, 220, 221, 223, 227, 229, 233, 236, 243, 245, 246, 253, 254, 266, 269, 270, 271, 281, 282, 283, 284, 371

I would move 29 and 198 to Group 2.  Also, 61 to 3a and 62 to 3b.

For North Dakota highways 200, 5, 13, and maybe highways 1, 3, 11, 18, and 32.
