Not sure if this has been discussed: have you noticed South Dakota has a county road naming system that's consistent throughout the entire state?
The northern border of the state is defined by a line of latitude. Any road along this line is called "100th St". The next section-line road to the south is "101st St", and so on, all the way down to the southern border. The western 3/4ths of the southern border is also a line of latitude, and this is "304th St". The eastern quarter of the southern border is formed by the Missouri River, which dips further south. The highest-numbered east-west road I see is "335th St", near the southeastern tip of the state.
There's a jog in the western border of the state: the line shared with Wyoming is almost a mile further west than the line shared with Montana. But I don't see any numbered roads right along the border; the westernmost numbered road I've seen is "124th Av", roughly between Whitewood and Nisland. But if you count section lines westward from there, it's clear that the western border was assumed to be "100th Av". This increases to the east, and by the time you get to the eastern border, you get as high as "488th Av".
This system appears to be consistent throughout the state. (Well, I see a few counties in the west that gave their roads names, instead of numbers, presumably because the terrain is such that the roads weren't surveyed along section lines. But it appears all counties that number their roads do so in accordance with this statewide system.) Are any other states organized in a statewide fashion like this?
Iowa appears to have some kind of a grid, but I do not know the details.
Michigan has county highways that start with a letter and end with a one or two digit number (e.g., A-2, B-72). This system started in 1970, and there are 8 lettered regions... A-F in the Lower Peninsula, G and H in the Upper Peninsula. Michigan Highways (http://michiganhighways.org/county/intercounty.html) describes it better than I could.
But coverage has always varied a lot from area to area. There are only two "D" routes, and zero "E" routes. Some counties have left the program, and others have given up on signage, so the only markers for a route are the ones erected by MDOT at junctions with state trunklines. And Michigan's official map has mistakes, such as including the nonexistent H-16.
There was also an earlier system of three-digit county highways, forming a grid across the state. Most of the ones I've seen are numbered 400-699, so of course there are repeats. Only a dozen or so counties still use these. I know they're signed in Mackinac, Marquette, and Montcalm (alliteration not on purpose).

Here you go (http://iowahighways.home.mchsi.com/highways/countyrd.html).
New Jersey has a system like this. If I'm correct, any 5xx County Route is inter-county and their numbers are consistent throughout the counties. (Basically, these are state-wide roads) Any 1-digit, 2-digit, 6xx, 7xx or 8xx County Route is local to that county only.
The original question was about street names. But since all the replies are about route numbers:
A number of states use alphanumeric designations:
California
Idaho
Illinois
Iowa
Michigan
New Mexico?
This list is incomplete; you can help by expanding it.
Others with statewide systems:
Florida (mostly former state roads in the grid)
New Jersey (5xx grid)

I've posted about it, and it's on my US 52 (http://www.alpsroads.net/roads/ia/us_52) page: "Iowa county routes are on a grid, so an "A" means you've encountered an east-west route at the top of the state. J's are at the bottom of the state, and then K through Z are north-south routes from west to east."

And Indiana's system is similar to that.
One of Virginia's secondary systems is a statewide system (school routes).
The normal secondary system is not statewide as such, but there WAS a definite pattern in how the entire system's roads were numbered in 1933. I have not cobbled it all together but I have found enough that there must be a reproducible pattern.
Note that the frontage road system, also a statewide system, is technically part of the primary system (this is why there are no F-series routes off of secondary routes in Virginia.
Mapmikey
Indiana's is not a statewide system, so much as a coutywide system replicated in every county statewide. They are all numbered by how many hundredths of a mile they are away (and in what direction) from a parallel road that passes through the county seat. The resulting format looks like "County Road 550 North", but the direction word is usually written as an initial, making it look more like a route number than a name.
I don't recall what is done for roads on the exact meridian or parallel through the county seat.
The meridian street is sometimes called "Meridian Street," like in Indianapolis and I've seen Base Road used for west-east roads. It may feature something with the words division, center or middle too. Usually though the roads are typically U.S. or state highways so they are often refered to by their highway number. And if none of that applies then it can be called 0 N/S. But you are correct in that this is not a statewide system but countywide, and there are some counties that do not use it, normally they are either urban counties (Marion, Lake, St. Joseph, Allen) or counties with rough terrain (some southern counties.)
QuoteIllinois
Only a few counties in Illinois use an alphanumeric. Several counties are numeric-only for their county routes, but only a few actually sign county routes, period.
Although there is no statewide grid in Minnesota, there are several counties/parts-of-counties in and around the Twin Cities that follow the streetnaming convention of the adjacent county...usually with systems originating in downtown Minneapolis with the river (southern Hennepin, Carver east-west streets), East Hennepin Ave in Minneapolis (Northeast Minneapolis, Anoka County, eastern Sherburne County, Isanti County), or an east-west line through the Minnesota State Capitol (Scott, Dakota, Washington, Goodhue, Dodge, Chisago Counties and Rock Creek in far southern Pine County).

Here you go (http://iowahighways.home.mchsi.com/highways/countyrd.html).
From a recent trip into Michigan, I've noticed that Leelanau and Benzie Counties still sign numeric county routes.
Nebraska has some kind of statewide county road numbering system, although only some counties use it. In this system N-S roads are labeled as Avenues and E-W roads are labeled as roads. Just like mile markers, numbers increase as you move eastward and northward. The numbers start at 702 at the Kansas border and at 310 at the Colorado border(no panhandle counties use the system, so that's as far west as it goes). Why the numbers start at that point, I can't figure out.
CT does not have a county route system, but they do maintain a system of Secret State Routes/State Service Roads. None are signed (with extreme rare exception), but sometimes appear on Google Maps or in Rand McNally. They all have higher numbers than signed state routes, and some categories are based on region. The categories:
400 series: Service roads near public facilities (ie roads that serve airports or state parks)
500 series: Roads in Hartford and Tolland Counties
600 series: Roads in New London and Windham Counties
700 series: Roads in New Haven and Middlesex Counties
800 series: Roads in Fairfield and Litchfield Counties
900 series: Connector roads less than 1 mile in length that connect two signed routes.
Illinois has no statewide numbering system as such. Most counties have a system that has each mile as equal to 1,000. Hence, there is a 0 line, and the next mile north is 1000, then 2000, and so on. A few counties around Chicago use State Street and Madison Street in the Loop as their baselines. These counties are Cook (obviously), DuPage, Kane, and Will.
Cook and Will use the straight address for their addressing system in unincorporated areas (and a fair number of municipalities). Hence, they will have 9601 West 159th Street (aka US-6) just west of 96th Avenue (aka LaGrange Road aka US-45). The streets go up one block every eighth of a mile (with the exception of Madison to Roosevelt - 12, Roosevelt to Cermak/22nd - 10, and 22nd to 31st - 9) such that the next mile street will be 8 more than the last mile street, i.e. 80th Avenue, 88th Avenue, 96th Avenue; 135th Street, 143rd Street, 151st Street, and so on.
DuPage and Kane use a slightly different numbering system also based off State and Madison. They will use the numbered streets (75th Street and the like), but they have a system that is based on the miles west of State and north or south of Madison. The system is as such: 9W326, 5N453, 2S006, and so on. The mile is noted in the first digit, the direction in the letter, and then the address number. Google, Bing, Mapquest, et.al. have a hell of a time trying to figure out unincorporated addresses there due to the system.

You should then see what several Milwaukee suburbs do. First they do an extension of the Milwaukee numbering system (1600 to a mile E/W and 800/mile N/S from the baseline in downtown Milwaukee.) to establish the grid numbers.
Then they put in grid format: direction letter of direction the road is not going in relation of the baseline, then block number in grid of direction the road is not going (15600 west would start off as W156 in the grid) then the direction on the road as it relates to the baseline, then finally the actual address number. (if actual address was 7200 north of the baseline on a N/S road, the 2nd part of the grid would be N7200) for a complete address of both parts together being W156N7200 Roadway Name.
I've never really understood the pattern to Kansas's county routes. For example, Cowley County has 1,3, 8, etc. McPherson County has 4 digit routes, some counties have none at all.
Then there's Harvey County. They number the routes, but the shields have the number written small on the bottom, with the county assigned road name written large... it seems odd. Example: http://goo.gl/maps/RfHZf

California's alphanumeric runs very roughly north-south from A to S, but I think only about half the letters are used. Some counties have quite a few routes (Santa Clara) while others have none at all (San Mateo). I would venture to say that signage of county routes is sporadic at best.
A Statewide numbering grid for numbered streets like SD would be a great idea everyplace. In Florida its county wide, although like NE 2 pointed out the roads in the Sunshine State about route numbers being a statewide grid, each county has its own numbering grid with street names. It would be great if all of the state (or any state) could adapt a grid system of some sort. Think about how easy it would be to find places, however we would be numbers instead of names again.

Does depend on the scale - a mix is best really. County grids and County names is going to trump "7684210 2845th St, Florida" Working as an address.

I found Lyon County to be particularly interesting...north—south county roads are lettered, and somehow it worked out perfectly that the west border is County Road A and the east border is County Road Z! (Any roads between letters get the letter+a number suffix, such as County Road R1, which is between County Road R and County Road S.)

Meridian Rd. is usually the N-S divider. Common names for E-W dividers are Division Rd or Base/Baseline Rd. You also see 00NS and 00EW.
To set the record straight, the base roads generally go through (roughly) the middle of the county, and the county seat (the courthouse) may or may not be close to the exact center of a county.
If a county is 27 miles wide, the north-south roads may go from 1300W to 1400E. You would never see a range of 1350W to 1350E.
A county line is either "County Line Rd" or more commonly, one side of the road is marked as the name for one county, and the other for the other county. For example, Howard County CR 1400E is also Grant County CR 1000W.
If a base road is also a state highway, INDOT would mark it "SR xx" or "US xx" on traffic lights, but the county might put up a street sign showing the county number. Other counties would have street signs saying "SR xx" or "US xx".
It appears Illinois may have tried to imitate the Iowa system, but only Lake and McHenry Counties adopted it. There are a couple random signs in northern Cook County that may indicate either a slow adoption by Cook County, or an attempt that was aborted.

The Iowa system is state-backed. Kansas has that 10,000-mile limit on its highway system, so in order for every county to have a consistent, state-wide system , I'm guessing that law would have to be repealed.
I presume each county decides what it wants to do with as far as a system goes. Linn County uses pentagons on some roads. I don't think any route is numbered lower than 500 and I know of a Route 1011. No other counties in southeast Kansas have anything like that and it's probably not necessary anymore since (nearly) every county has an E911 system.
Harvey County's pentagons are, I think, a compromise of sorts. Everyone probably calls the road by their names (which are typically an extension of Wichita's [West, Ridge, ect.] or Newton's [Kansas]) so the county makes them the primary feature on the shield.
I recall Edwards County used to have route numbers in plain white squares. Logan County once had route numbers within a white circle on a red background.

New Mexico counties each have their own system. Some are just numeric, others alphanumeric, and then Guadalupe County seems to make their routes case sensitive as well. The most systematic numbering scheme in the state is San Juan County (Farmington, northwest portion of state). It has a four-digit numbering system with lowest numbers in the north and west, and highest numbers in the south and east. Even non-county maintained routes get a number in the system, with a different color sign.

state highway mileage. A county road is not (usually) a state highway.
Most of these replies have been about the system (or lack thereof) that each state uses to assign numbers to its county roads.

I've changed it now to "county road naming systems", because what I wanted to point out is the way South Dakota names their section-line roads consistently across the entire state. It's similar in concept to a city street grid in a typical midwestern metro area, except that it's been implemented on a statewide scale. What I was wondering is whether or not any other states do this.

You assume the road doesn't have a proper name. Which may be true in this case. But in some places, roads that are signed with county-route pentagons or squares have actual names as well. (Example: Fairfield County, OH.) In some places, signed state highways also have local names other than "State Highway XX". (Example: Franklin County, OH, and not just the urban areas.) I would assume the post office and emergency services use these names when they exist.

It looks like North Dakota does this, at least most counties do. The originating point appears to be at the corner of Main St and Center Ave about 40 miles north of Bismarck.
IIRC, Manitoba, Saskatchewan, and/or Alberta has a province-wide numbering system that begins at one of the southern corners. It looks like the new Google Maps saw the deletion of the names of most of the rural streets in Canada.

I think there was some sort of county road numbering system developed by KDOT and/or its predecessor. From what I can tell, it follows the Even/Odd rule for US and interstates, starts at 300 at the Nebraska line, 301 at the Colorado Line, and increases by 2 for every mile heading heading east/south.
In Douglas County, we have 438, 442 (2 segments), 458, 460, 1023, 1029 (also 2 segments), 1039, 1045, 1055, 1057, and 1061.
Scott, assuming Linn County is using the same system on it's pentagon-signed highway, numbers in the 500 series makes sense, but 1011?
QuoteThe one state where I've noticed it is Indiana. Not sure if it's universal, but it's pretty omnipresent in my travels.
Indiana's are at the county level...while most counties in the state follow a similar format, each is formatted to their own county.

Don't recall offhand if Iowa's is a statewide system or at the county level.

Yes, you're right. In fact, it appears that particular junction of section lines was chosen as the zero point because it's very close to the actual geographic center of the state. I found some coordinates that place the
exact geo center about one mile due west of the county-road-naming-zero-point. So why was the zero point placed one mile east of the geo center? My best guess is because that's also a point common to three townships in Sheridan County: McClusky Twp, Pickard Twp, and Edgemont Twp.
So, heading north, the Canada border is just past 109th St North. Heading south, the South Dakota border is called 102nd St South... which could be confusing because that almost (but not quite) matches up with South Dakota's system, which (as I described in the OP) refers to that road as 100th St.
And you're also right that (unlike SD) there are some counties that use their own numbering system. Burleigh Co. and Ward Co. use extensions of Bismarck's and Minot's zero points, respectively. Grand Forks Co. uses a zero point in the SE corner of the county.

I don't recall what is done for roads on the exact meridian or parallel through the county seat.
Base Road is used as the name for those roads, and then "N Base Road, W Base Road" etc to distinguish between the two. As someone who used to deliver pizza out in the country it's a good system. Drawback is you can go around a slight turn and be on a different road name sometimes.
Anyway, not every county uses that system in Indiana. Brown County doesn't use it at all and just has named roads. Monroe County seems to use a mix of named roads and a few county roads.
I know my county switched over all their roads when they setup 911 service about 20/25 years ago. Back then nobody in the country had a fixed mail address, they were just "Rural Route 2", etc. So probably some of the other counties that had road names and addresses might have had a harder time switching.

Kansas has that 10,000-mile limit on its highway system, so in order for every county to have a consistent, state-wide system , I'm guessing that law would have to be repealed.
what
The limit is on state highway mileage. A county road is not (usually) a state highway.
I had thought we were talking about a system like Missouri, where the roads are state maintained.

I've never really understood the pattern to Kansas's county routes. For example, Cowley County has 1,3, 8, etc. McPherson County has 4 digit routes, some counties have none at all.
I presume each county decides what it wants to do with as far as a system goes. Linn County uses pentagons on some roads. I don't think any route is numbered lower than 500 and I know of a Route 1011. No other counties in southeast Kansas have anything like that and it's probably not necessary anymore since (nearly) every county has an E911 system.
I think there was some sort of county road numbering system developed by KDOT and/or its predecessor. From what I can tell, it follows the Even/Odd rule for US and interstates, starts at 300 at the Nebraska line, 301 at the Colorado Line, and increases by 2 for every mile heading heading east/south.
In Douglas County, we have 438, 442 (2 segments), 458, 460, 1023, 1029 (also 2 segments), 1039, 1045, 1055, 1057, and 1061.
Scott, assuming Linn County is using the same system on it's pentagon-signed highway, numbers in the 500 series makes sense, but 1011?
But, that doesn't explain Cowley County having 1, 3, 8, etc.

I don't know if Linn County happened to use a system already in place of if it used something else. I may have also gotten that number wrong. I remember it as 1011 but Google Maps shows it as 1095. It actually runs concurrently with K-152 for a bit west of LaCygne.
The route that links Blue Mound and Parker is marked 1077 on Google maps. I knew it was a county route but I couldn't have guessed the number. I think those are Linn County's only north-south marked routes.
Linn County 566 serves as a shortcut for people who want to get from Parker to Blue Mound without having to go up through Mound City.

Most of these replies have been about the system (or lack thereof) that each state uses to assign numbers to its county roads. But that's not what the OP was about (and it was largely my fault for the way I worded the thread title). I've changed it now to "county road naming systems", because what I wanted to point out is the way South Dakota names their section-line roads consistently across the entire state. It's similar in concept to a city street grid in a typical midwestern metro area, except that it's been implemented on a statewide scale. What I was wondering is whether or not any other states do this.
Just to make it clear, my response for Nebraska did intend to refer to a system similar to South Dakota of naming county roads along section lines with numbers and not numbering in the sense of having route markers. Although Google maps just recently started marking some of the numbered and lettered county roads with rectangular markers, implying that they have route markers, which is not the case. The only place you will see the numbers are on regular street signs.

I was wondering about the Dxx and Rxx highways in Peoria County I've seen on maps, including the Peoria County Highway Department map. It looks like a few (if not all) of them are signed (GSV link (http://goo.gl/maps/MFRv0)). Do you think that would have been the same idea?
It appears Peoria County would be far enough south to be in the D range so it's certainly possible.

The concurrences in Wisconsin are mainly because of a matter of convenience to not use more than 1 letter for a logical routing. For example, Let's take Dodge and Green Lake County A.
Hwy A starts at Wis 26 south of Juneau and heads north-northwest 17 miles to Fox Lake. Just before Fox Lake, Hwy C joins A for a short 1/2 mile to connect to Wis 68. Both Hwy A and C follow Wis 68 for a 1/4 mile to Wis 33. Hwy C turns South (East 33) while Hwy A continues west on 33 for 2 miles before turning north. After 5 miles, Hwy A comes to Hwy AW which is the county line. Hwy A turns east on AW for 1/4 mile before turning north again to enter Green Lake County. Hwy A continues north 8 miles to Wis 44 before another short 1/2 mile cosign east and turn north again. Hwy A goes another 8 miles north to Wis 23/49 on the east side of Green Lake. Hwy A, prior to a reroute about 10 years ago, used to go through Downtown Green Lake. Hwy A cosigns with 23 for 1 1/2 miles before turning north again 2 miles to Hwy J. Turns west for 1/2 mile before turning north again. It goes another 6 1/2 miles before finally ending at Wis 49 just south of Berlin.
If each turn off of a state highway cosign was a new letter, the route would need 5 letters instead of 1 for a length of 51 3/4 miles.
BTW, someone asked if there was a "system" for the letters in Wisconsin. As far as I know, the letters are somewhat random however sometimes they have some logic behind the letter chosen. Hwy KR, for example, is the county line between Kenosha and Racine Counties. Also pretty frequently one county will carry over the previous county letter such as Hwy A that I described earlier and Shawano/Outagamie/Winnebago/Fond du Lac/Dodge County M.
The one thing that a traveler must realize is that sometimes when a county route enters an incorporated area the highway letter is not always signed until you leave town again. For a long time, even though Hwy T went in to Princeton on Farmer St, it just seemed to disappear. The DOT has since rectified that with signage for Hwy T off of Wis 23/73.

California...
California's alphanumeric runs very roughly north-south from A to S, but I think only about half the letters are used. Some counties have quite a few routes (Santa Clara) while others have none at all (San Mateo). I would venture to say that signage of county routes is sporadic at best.
I hate the California system of county road names. No one tells anyone "Just take route N8." There's routes with state road gaps in them that have nonsensical county route numbers assigned. Another is San Diego County Road S80, aka old US 80. However, San Bernardino County Road 66 (old US 66) seems to have broken the alphanumeric system. Also CalTrans won't acknowledge county roads on freeway signs. The signs are either placed on their own post directing motorists, or they're nailed to the freeway signpost.

Also CalTrans won't acknowledge county roads on freeway signs. The signs are either placed on their own post directing motorists, or they're nailed to the freeway signpost.
Sorry to chime in here so late, but I agree, CA's county road system needs improved signage to be useful.
N8 is a bad number, N39 makes more sense as it tries to fill in the 39 gap.
I believe the La Cienega Expressway between I-10 and I-405 should also get some type of highway number.
This website tries to make sense of the system: http://www.cahighways.org/county.html

Not sure if this has been discussed: have you noticed South Dakota has a county road naming system that's consistent throughout the entire state?
The northern border of the state is defined by a line of latitude. Any road along this line is called "100th St". The next section-line road to the south is "101st St", and so on, all the way down to the southern border. The western 3/4ths of the southern border is also a line of latitude, and this is "304th St". The eastern quarter of the southern border is formed by the Missouri River, which dips further south. The highest-numbered east-west road I see is "335th St", near the southeastern tip of the state.
There's a jog in the western border of the state: the line shared with Wyoming is almost a mile further west than the line shared with Montana. But I don't see any numbered roads right along the border; the westernmost numbered road I've seen is "124th Av", roughly between Whitewood and Nisland. But if you count section lines westward from there, it's clear that the western border was assumed to be "100th Av". This increases to the east, and by the time you get to the eastern border, you get as high as "488th Av".
This system appears to be consistent throughout the state. (Well, I see a few counties in the west that gave their roads names, instead of numbers, presumably because the terrain is such that the roads weren't surveyed along section lines. But it appears all counties that number their roads do so in accordance with this statewide system.) Are any other states organized in a statewide fashion like this?
Oh... finally something I know about!!!! :biggrin: (and sorry for posting so late)
There is a 104th Avenue near my house, and also 100th Court on the Wyoming border.
Us West River counties only use the grid where it's flat enough to support the enterprise. Also even if the road is named it does not mean it doesn't fit the grid (200th Street is named Homestake Road in Lawrence County)
For other states I know about Iowa, Nebraska, and North Dakota. Utah and southern Idaho have those city-grids, so those don't count.

California's alphanumeric runs very roughly north-south from A to S, but I think only about half the letters are used. Some counties have quite a few routes (Santa Clara) while others have none at all (San Mateo). I would venture to say that signage of county routes is sporadic at best.

Part of the problem, at least in Santa Clara county, is the county routes are better known by their names rather than the route number. For example...
* CR-G2 is known as Lawrence Expressway
* CR-G3 is known as Page Mill Road
* CR-G4 is known as San Tomas Expressway and Montague Expressway
* CR-G7 is known as Bloomfield Avenue
In fact, I'm not aware of any county route that is not already named although I'm not 100% sure of this.
