What state routes are the most important, and least important in your state?
I'll start with Missouri:
SR 5 - Carries traffic from Iowa enroute to Arkansas.
SR 21 - Carries traffic from St Louis to Arkansas.
SR 19 - Carries traffic from the southern half of the state to the northern half.
SR 30 - Reliever for SR 21.
SR 110 (Jefferson County) - Connects US 67 to SR 21.
M Highway (Jefferson County) - Connects I-55 to SR 21, also carries truck traffic from a quarry along the highway. Also is a bannered, divided highway, oddly rare for a state secondary.
SR 72 - Connects Ironton to US 67.
E Highway - (Jefferson/ St Francois Counties) - Connects DeSoto to Bonne Terre.
Whoa..... this one is gonna be a lot tougher than the US route thread. I'll attempt to do New Jersey and Virginia. Someone feel free to move these up or down as they see fit, because like I said it's tough

NJ 29
NJ 24
NJ 208
NJ 4
NJ 18
NJ 15
NJ 70
NJ 49
EDIT: I squeezed VA 8 in there too
For NJ, if the criteria is carrying traffic between neighboring states then I'd include NJ 90, NJ 73, and NJ 38 (Philadelphia to NYC via the Turnpike), and NJ 139 and NJ 495 (NYC to PA via I-78 or Delaware via I-95)
Connecticut:
Top state routes are probably these four, in that order. Then it drops off and ranking is more difficult:
8
9
15 (longer, but supplements I-91 and I-95)
2
For the least important routes, I'll list the ones the state wanted to get rid of but still had to retain:
125
151
152
166
174
176
305
314
Indiana:
37 is the major connector between Indy and Bloomington (though soon to be replaced by I-69)
25 carries a lot of traffic between Logansport and Lafayette
63 is the southern half of the best route between Chicago and Terre Haute
46 Terre Haute-Bloomington-Columbus
26 Kokomo-Lafayette
Probably the next tier would be some of the longer routes connecting several of the smaller county seats, like 3, 9, 15, 32, 39, 56
Least important has to be 520.
99 by a country mile in Califronia. 58 is pretty high up there as well.
Off the top of my head, in Ohio, I would say
2,3,4,5,7,11,12,13,15, and 32 are all up there. I'm sure there are others, but that's what comes to mind immediately.
At the bottom would be ones like 450 and 435 which are basically glorified ramps.
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?
Some of the top routes in NY (not in any particular order):
-NY 5
-NY 17
-NY 12
-NY 332
-NY 104
-NY 31
-NY 22
-NY 27
-NY 63 (mainly between Mount Morris and Batavia)
-NY 13
-NY 37
-NY 28
-NY 149 (mainly west of US 4)
-NY 7 (mainly east of I-890)
-NY 25
-NY 135
-NY 3
-NY 481
The least important road in the state, by far, is undoubtedly NY 421.
I'll try the Carolinas since Virginia has been attempted...

Thanks. And I definitely can't believe I forgot to add NJ 139 and NJ 495. Matter of fact NJ 495 is #1.

I'm going to go with the most major ones only.
- Maryland Route 295 - forms the northern half of the Baltimore-Washington Parkway.
- Maryland Route 100 - a freeway connecting Howard and Anne Arundel counties.
- Maryland Route 200 - a much-needed toll shortcut between Gaithersburg and Laurel, in the northern suburbs of D.C.
- Maryland Route 2 - it's the state's longest state-maintained highway, covering about 80 miles from downtown Baltimore to Solomons at the southern tip of Calvert County, and also passes through the Annapolis area.
- Maryland Route 4 - connects Washington, DC with Southern Maryland, and along with Route 2 forms a main drag through Calvert County; it passes through or by three county seats: Upper Marlboro (Prince George's), Prince Frederick (Calvert) and Leonardtown (St. Mary's).
- Maryland Route 404 - from the Bay Bridge, people can make their way down U.S. Route 50 to "the 404" and take it into Delaware, and to the Delaware beaches or to Ocean City, Maryland; "the 404" also provides Caroline County seat Denton with a bypass.
- Maryland Route 3 - part of the Baltimore-Richmond alternate route that also includes portions of I-97 and U.S. 301.
- Maryland Route 5 - another connector between Washington, DC and St. Mary's County; it forms a Waldorf-Leonardtown-Point Lookout corridor.
- Maryland Route 32 - another Howard-Anne Arundel freeway, and also a surface road from Clarksville to Carroll County seat Westminster.
- Maryland Route 90 - takes drivers into Ocean City via a freeway.
- Maryland Route 97 - connects Washington, DC with Gettysburg, Pennsylvania via Westminster.
- Maryland Route 140 - serves Baltimore's northwest suburbs, then passes through Westminster, Taneytown and Emmitsburg.
- Maryland Route 213 - an Upper Shore alternative to U.S. 301; it connects three county seats: Elkton (Cecil), Chestertown (Kent) and Centreville (Queen Anne's).
- Maryland Route 24 - links Harford County seat Bel Air with I-95 and the Aberdeen Proving Ground.
- Maryland Route 313 - from about Denton to Mardela Springs, it's a Lower Shore complement to U.S. 50.
- Maryland Route 30 - picks up where I-795 leaves off at Reisterstown; it bypasses Hampstead in Carroll County, and runs directly up to Hanover, Pennsylvania.
- Maryland Route 45 - feeder for I-83, but not worthless; it serves the commercial areas of Towson, Lutherville-Timonium, Cockeysville-Hunt Valley, Sparks and Hereford.
Less than two dozen numbered state highways in Alaska (including disconnected fragments of 7 and 10), so this is easy. From top to bottom (* indicates mostly or entirely closed in winter):
1
3
2
9
4
11 (for economic importance, despite low ADT)
7 (Haines)
98
7 (Juneau)
7 (Ketchikan)
10 (Chitina)
6*
5*
7 (Petersburg)
10 (Cordova)*
8*
If unnumbered state highways were included, many of the routes or segments at the bottom of the list would be outranked, especially by the unnumbered short freeways in Anchorage and Fairbanks. Some key Alaska Marine Highway auto ferry routes too, especially the mainlines through southeast Alaska.
For Hawaii, a similar list is harder, but the hierarchial numbering system (2 digits for primary routes, 3 digits for secondary routes, 4 digits for lesser urban routes) would be a good starting point.
I'll just go with a top five for Georgia:

Edited to add MA 142 to list
Arizona has several that are important regional connectors outside of the obvious urban freeways like; 101, 51, 143, 202, and the 303:
- 87, big connector for Payson and the Valley, one of the better short cuts between the Phoenix area to I-40.
- 264 is a big state route corridor in the Hopi and Navajo Nations.
- 260 runs almost the entirety of the Rim out to Yavapai County
- 89A still moves a decent amount of traffic between Prescott Valley all the way up to Flagstaff.
- 95 has two largely urbanized sections north of Quartzsite.
- 68 is a good expressway route from US 93 almost all the way to the Nevada State Line.
- 69 is the expressway for Prescott to I-17.
- 89 is still handy when I-17 is shut down and gets you from US 93 to I-40.
- 80 still is the main road for all the cities in the southeast corner of the state south of I-10.
- 77 has value given the huge length from Tucson to the Navajo Nation...although the multiplexes of US Routes waters it down a lot.
- 85 is a huge bypass of the Phoenix Area and major expressway.
- 86 really is the only main road west out of Tucson.
Florida has lots of SRs. So an exhastive list eould be more time than i am willing to devote and i am not considering any that are secret SRs hidden under US routes or interstates.
I am also looking at long distance travel. In metro areas some SRs have huge numbers in short spurts like SR21 just south of 295 in Jacksonville and Clay County or something like the SR 70 breezewood near Ft Pierce

Frankly, this is just silly.
Most of them are "locally important" but in most states, few are used for long-distance travel, or they've been supplanted by US Routes/Interstates.

I think the 20-40-50-60-70-80 SRs might be the most important corridors, a few of the odd-numbered two-digit SRs, or three-digit SRs matter much, except on a local basis. Most odd-numbered, but non-secret SRs are not very long nor are they very direct (local importance).

Would have huge importance in Bay Area though.
In the Wine Country CA-29, CA-121, CA-37 and CA-12 would have importance.
In Sacramento Area yes besides CA-99 though CA-113 is important because that gets used as a bypass for I-5.
Nobody else is going to try a full ordering? I know it's almost impossible for Kentucky, but most states are doable.

8, 315 & 126 would definitely be up there for having important freeway segments in metro areas.

It would be exhaustive for me to rank Iowa's 100ish highways, and who am I to judge whether Highway 70 (https://en.wikipedia.org/wiki/Iowa_Highway_70) is more important than Highway 39 (https://en.wikipedia.org/wiki/Iowa_Highway_39)?
Alabama has very few state routes that are overly important, although some of them are rather long. The ones that are probably hatthe most important:
59: connects I-65 with the beaches
157: half of the route that connects Birmingham with Florence (along with I-65 from Birmingham to Cullman)
20: connects Decatur with Florence
21: the segment from Sylacauga north towards Talladega, Anniston and Jacksonville is far more important than the segment south of Montgomery
55: leads (via U.S. 84) from I-65 towards the Florida beaches
150: major east-west thoroughfare in Hoover, although most of the traffic is local traffic between I-459 and U.S. 31
119: serves as a major connector between U.S. 31 and U.S. 280 in Shelby County
That said, most of the longest state routes in Alabama have long since lost their usefulness, including 5, 10, 14, 17, 22 and 69.

Agreed. I would say that only a handful of states are doable. Ohio has over 500. It's not really realistic to force-rank them all.

Good point. I was mostly thinking distance. For the reason you cited, I would nominate all three of these freeways as candidates for 3di designation. (377 or 477, 371 or 871, and 671 respectively).
Wisconsin is tricky. The two top ones are obvious:
29
35
After that though you have a lot of routes running in concert with other nearby corridors or redundant to other US/interstate routes. 11, 13, 27, 70, 77, and 93 are part of the second tier.

AL 255 is important to Huntsville and the Redstone Arsenal, with a high daily traffic count. But at roughly 10 miles, it's only of local importance.
AL 69 is a great lazy-day sampler though various parts of Alabama, but I don't think it was all that meaningful a route...did a vaguely diagonal route from Jackson to Guntersville serve some sort of purpose? Tuscaloosa is the only significant city in between. (I also like that it "piggy-backs" I-69, I-359, US 11, US 84, US 80, US 43, and US 278 along the way, which is either terrible or awesome depending on one's point of view.)

SR-5 is the really weird one, going generally NE-SW between Thomasville and Birmingham, then NW-SE between Birmingham and its terminus at US 278.
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)

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

Less than two dozen numbered state highways in Alaska (including disconnected fragments of 7 and 10), so this is easy. From top to bottom (* indicates mostly or entirely closed in winter):
1
3
2
9
4
11 (for economic importance, despite low ADT)
7 (Haines)
98
7 (Juneau)
7 (Ketchikan)
10 (Chitina)
6*
5*
7 (Petersburg)
10 (Cordova)*
8*
If unnumbered state highways were included, many of the routes or segments at the bottom of the list would be outranked, especially by the unnumbered short freeways in Anchorage and Fairbanks. Some key Alaska Marine Highway auto ferry routes too, especially the mainlines through southeast Alaska.
For Hawaii, a similar list is harder, but the hierarchial numbering system (2 digits for primary routes, 3 digits for secondary routes, 4 digits for lesser urban routes) would be a good starting point.
Is there anywhere I could find traffic statistics for Alaskan state highways, out of curiosity?

Wisconsin is tricky. The two top ones are obvious:
29
35
After that though you have a lot of routes running in concert with other nearby corridors or redundant to other US/interstate routes. 11, 13, 27, 70, 77, and 93 are part of the second tier.
47's probably pretty high up there too - main N-S drag through metro Appleton and goes through no shortage of other towns as well.

Have you looked through the Alaska DOT&PF website? I recall finding them there, somewhere.

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
Now
that's one exhaustive list! Kudos to DT for assembling it. :clap: That being said, there's a few modifications I'd make:
(a) 62 should be moved up to group 3B for at least the reason that 247, also in 3B, terminates at it. Otherwise, it connects a distinct region (Yucca Valley-29 Palms) with a major arterial (I-10) in one direction and a recreational area (Lake Havasu) in the other -- aside from actually crossing a state line.
(b) 29, 33, and 44 should be moved up a notch to group 2, as they all serve as major inter-regional routes (yeah, I consider Clear Lake separate from the greater Bay Area).
(c) I'd consider 70 to have state/interstate importance as a lower-elevation alternative to I-80 and more likely to remain open when Donner is shut down. Its former Alternate US 40 status was a manifestation of that reality -- it, IMO, should be in Group 1.
(d) 173 deserves demotion to group 4A simply due to its severance in the middle; one section simply connects CA 138 to Silverwood Lake while the other only connects CA 18 (and 189) to the east side of the Lake Arrowhead residential area.
A crude take on Louisiana:
1 is by far the longest and most important. It serves as a bypass or alternate route for I-49 and US 71. It is a major route along the west side of the Mississippi River between Port Allen and Donaldsonville. It forms the "main street" for the communities between Donaldsonville and Golden Meadow. And it connects Grand Isle and Port Fourchon to the rest of civilization.
23 is a major highway that connects the lower Mississippi River delta to the rest of civilization.
28 is a major route in central Louisiana, connecting Fort Polk and Natchez via US 84. It is significant enough to come up frequently in conversations about the proposed I-14.
There are a handful of significant 3xxxx routes: 3132 around Shreveport, 3127 and 3125 along the Mississippi River, the Earhart Expressway (number escapes me at the moment).
I'm having trouble thinking of other Louisiana routes that are this significant. The interstates and US highways serve virtually all of Louisiana's major cities and towns. Quite a few 2d and 3d routes are significant arteries, but I don't think any other than the ones I list above provide appreciable interparish navigation.

I'd swap the group locations of 108 and 198. 108 really outside of the Central Valley is just a small connector route, plus it is one of the winter passes that shuts down in the Sierras which indicates it isn't much more than a scenic route. 198 has a pretty substantially large freeway/expressway section and is the direct route to a National Park. Plus it doesn't hurt 198 that it does connect three major routes; US 101, I-5, and CA 99.
New Jersey i would say the top SRs are 3, 4, 42, 38, 31, 29, 18, 55, 70, 73, 23, 47, maybe 72, 37 and 35 in the summer. Of course for NJ everything is Route xx regardless of I, US, SR or CR so many (regular non road geek) people make no distinction

Florida has lots of SRs. So an exhastive list eould be more time than i am willing to devote and i am not considering any that are secret SRs hidden under US routes or interstates.
I am also looking at long distance travel. In metro areas some SRs have huge numbers in short spurts like SR21 just south of 295 in Jacksonville and Clay County or something like the SR 70 breezewood near Ft Pierce

I think the 20-40-50-60-70-80 SRs might be the most important corridors, a few of the odd-numbered two-digit SRs, or three-digit SRs matter much, except on a local basis. Most odd-numbered, but non-secret SRs are not very long nor are they very direct (local importance).
I did not catch onto this until Summer 2013, which is when I started looking very in-depth at Florida's roads on Google Maps. I find it very fascinating that many of Florida's SR x0 (20, 40, 70, etc.) state highways are so significant, many of which may go all the way from the Gulf Coast to the Atlantic Coast, passing through significant towns, cities, and more. Then, of course, there is the large arrangement of triple-digit state highway toll roads in Florida (such as FL 408, FL 528, FL 589, etc.), which I also find to be intriguing - and as mentioned, Florida's Turnpike has a "secret" designation as FL 91. I feel like Interstate 4 also has a "secret" concurrency with FL SR 400 (correct me if I'm wrong), which I find to be interesting.

Like Georgia all Florida US routes and interstate routes have secret SR numbers. However Florida has a grid.
Major diagonals SR are x00. Odd x00 is NW to SE and even x00 NE to SW. I-4 is 400 us 92 is 600

I wouldn't say they're high enough yet. The portions of 130 with good traffic counts are duplexed with 45.
I probably should have thrown 78 and 289 in there as well.

Aside from the important 4xx series of state highways in Georgia, including GA SR 400, that are secretly concurrent with existing interstates and freeways, or cancelled ones (as in GA 400's case), which are obviously the most important state routes in the state of Georgia, I have compiled a list of the possible most important Georgia State Highways, in different tiers (note that my tiers are not categorizing
all or
most GA state routes, but categorizing the ones I think are possibly the most important):
TIER # 1 => UNDENIABLY, UTMOST IMPORTANT GEORGIA STATE ROUTES:* GA SR 316 - This road is vital in connecting much of Georgia, the Atlanta Metro Area, and places elsewhere with Athens, Georgia. The westernmost section of this road is limited-access, and slowly but surely more of it is being upgraded to such standards. While much of GA SH 316 is concurrent with US Highway 29, nonetheless it is still important. Roughly the entirety of this road is clogged up with traffic in the autumns, due to college football traffic heading to and from the University of Georgia (which is in Athens) - as a matter of fact, the road is called
University Parkway - so we can only imagine what kind of hell would occur if this road wasn't even there.
* GA SR 141 - This road has a lot of importance. It is a crucial artery through the
Buckhead uptown district of Atlanta, it is also an important artery through Brookhaven and Chamblee, it has a short limited-access section northeast of I-285 with some relatively high traffic counts, it is a critical artery through the growing suburb of Johns Creek (which is in Fulton County), and it is important elsewhere in suburbia.
* GA SR 300 - This road is vital in connecting I-75 Southbound traffic with Albany, Georgia. It is four-lane the whole way, whether at some points it is a divided highway or a single roadway with four travel lanes and a center turn lane. The rest of the route is concurrent with US Highway 19 going south until the Florida state line (that entire section of road is also multi-lane).
TIER # 2 => GEORGIA STATE ROUTES THAT ARE DEFINITELY IMPORTANT, BUT JUST HOW IMPORTANT THEY ARE IS SLIGHTLY DEBATABLE:* GA SR 540 (FUTURE) - This is going to be the future designation for the entire Fall Line "Freeway," from Columbus to Macon to Augusta, once it is completed.
* GA SR 520 - This is concurrent with other highways for most of its route (such as US 27, US 280, US 82, & US 17), but it does have a solo section from Richland to Dawson (in between US 280 & US 82), and its easternmost segment is solo from US 17 to its end on Jekyll Island. Almost the entirety of this road is multi-lane.
* GA SR 515 - This road is the gateway from the Atlanta Metro Area to the Appalachian Mountains. When I-575 ends going Northbound, this road is what it turns into. This road is part of the Appalachian Development Highway System (ADHS) (https://en.wikipedia.org/wiki/Appalachian_Development_Highway_System). While, for much of its route, GA SH 515 is concurrent with other highways (such as US 76, GA 2, & GA 5), nonetheless it is still important, and it is solo on its two-lane, northernmost section, which helps to connect US Highway 76 (in Georgia) and US Highway 64 (in North Carolina).
* GA SR 20 - This road is certainly significant, and so much so that I
probably should have actually put it in
Tier # 1, but I'll leave it here for now. Much of the proposed Outer Atlanta Beltway would have actually paralleled GA SH 20, including the proposed section that is known as the
Northern Arc. With that said, it is needless to say that Georgia Highway 20 connects many Atlanta Metro Area suburbs and exurbs (such as Cartersville, Canton, Cumming, Buford, Lawrenceville, Conyers, & McDonough). GA 20 also assists US 411 (because it is multiplexed with it) in connecting Rome to Cartersville and I-75 Northbound traffic as a divided highway. GA 20 also does a significant job of being a main artery within Rome, and it connects it with parts of the state of Alabama.
* GA SR 53 - This road is quite a significant Georgia State Route. One of the most important jobs it does is connect Rome to Calhoun and I-75 Southbound traffic as a four-lane highway (mostly a divided highway but with a few sections that are multi-lane and undivided). GA SH 53 also connects countless significant communities in Georgia - some larger (like Gainesville), and some smaller (like Jasper). GA 53 also has a couple of bridges over Lake Lanier, with one of them being an old, two-lane, steel truss bridge (which I personally plan to film and take pictures of in the next month) that is scheduled to be taken down soon.
* GA SR 21 - This road is concurrent with all of Interstate 516 in Savannah. Also in Savannah, GA SH 21 comes in close proximity to both the Savannah Port and the Savannah/Hilton Head International Airport, which makes it quite significant. From there, GA 21 is a multi-lane highway that serves and connects
many communities, and might
possibly funnel in some Savannah-Augusta traffic (correct me if I am wrong). It does do an important job of connecting outer development in the Savannah area to Savannah itself.
TIER # 3 => GEORGIA STATE ROUTES THAT ARE POSSIBLY VERY DEBATABLE WHEN REGARDING IMPORTANCE:(-my own input on GA's state route hierarchy coming very soon, this research is taking longer than usual-)
Ranking every state route in a particular state would involve splitting hairs to an unimaginable degree. I think that if you wished to evaluate the the importance of such a long list of routes, sorting them into several categories would be a more feasible way to do this. For example, sort them into categories of high, moderate, and low importance, perhaps adding an extra two categories of "very high" or "very low." 3-5 should be enough. There's no need to separate 200+ routes into 200+ different levels of importance lol

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 will say that is an impressive list you have set up.
(-replies to a few quotes coming soon, so sorry for so much waiting-)

What state routes are the most important, and least important in your state?
I'll start with Missouri:
SR 5 - Carries traffic from Iowa enroute to Arkansas.
SR 21 - Carries traffic from St Louis to Arkansas.
SR 19 - Carries traffic from the southern half of the state to the northern half.
SR 30 - Reliever for SR 21.
SR 110 (Jefferson County) - Connects US 67 to SR 21.
M Highway (Jefferson County) - Connects I-55 to SR 21, also carries truck traffic from a quarry along the highway. Also is a bannered, divided highway, oddly rare for a state secondary.
SR 72 - Connects Ironton to US 67.
E Highway - (Jefferson/ St Francois Counties) - Connects DeSoto to Bonne Terre.
In California, we have some very long distance state routes (1 and 99 and 41 come quickly to mind) and others that are of great regional importance (like 12, 20, 299, 180, 91, 198, 58, 46, 152, etc) and then there are the essential local freeways (like 85, 87, 55, 57, 51, 168, 24, 4, 92, 84, 22, etc) some of which are part of longer routes (not all of which is freeway)
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.
