Hierarchy of state routes in your state?

[Buck87]

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.

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

[pianocello]

Nobody else is going to try a full ordering? I know it's almost impossible for Kentucky, but most states are doable.

It would be exhaustive for me to rank Iowa's 100ish highways, and who am I to judge whether Highway 70 is more important than Highway 39?

[Charles2]

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.)

WV 7
WV 9
WV 10

There are a couple other routes (WV 61, WV 705) that are very important in certain areas (Charleston, Morgantown) but aren't that important on a statewide or regional basis.

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)
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

[20160805]

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

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.

GROUP 3a: Secondary urban or local routes (including shorter freeways)

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 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.   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.

[jbnv]

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.

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'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

Would Texas Highway 130 be considered to be significant, or are the traffic counts not high enough?

(-replies coming to a few quotes, sorry for the wait and such)

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.

I'll just go with a top five for Georgia:

1. 401
2. 403
3. 402
4. 405
5. 404

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). 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-)

[paulthemapguy]

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

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 will say that is an impressive list you have set up.

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)
