Hierarchy of state routes in your state?

[ColossalBlocks]

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

VA 7
VA 267
VA 28
VA 76
VA 168

NJ 208
NJ 4
NJ 18
NJ 15
NJ 70
NJ 49

EDIT: I squeezed VA 8 in there too

[bzakharin]

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)

[kurumi]

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

[NWI_Irish96]

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.

[Max Rockatansky]

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

[frankenroad]

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.

[Brandon]

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?

[vdeane]

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...

South Carolina:
SC 9

SC 121
SC 72
SC 11
SC 151
SC 22
SC 31
SC 34
SC 170
SC 41

NC 87
NC 24
NC 49
NC 11
NC 12
NC 540
NC 16
NC 18
NC 147
NC 226

[plain]

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)

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

[TheHighwayMan3561]

Minnesota I'll throw these out there (not in order):

100
23
60
371
36
24 (north of I-94)
65 (Cambridge-Minneapolis)
55 (Buffalo-Inver Grove Heights)
62

[epzik8]

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.

Edited to add MA 142 to list

[Max Rockatansky]

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

CT 10 should probably also be up there.

[formulanone]

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'll just go with a top five for Georgia:

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

Curiosly, I think "400" might be the best-known "semi-secret state road".

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).

[Big John]

^^ 400 is openly signed while the others are not.

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

CA 14
CA 60

CA-24
CA-17
CA-82
CA-85
CA-87

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.

[hotdogPi]

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