I recently saw we just had a thread about the largest (in population) cities without an Interstate connection or a US Highway connection.
So I thought, what if we applied the same idea to counties? What is the largest county without a US Highway or an Interstate?
I'll start off by naming my county, Brazoria County, Texas. It only has state highways, but it has a population of approx 370k (in 2018 per Wikipedia)
I'm curious to see which county is the largest in each state!
In Indiana, Monroe County is the largest without a US highway at 137,974.
Howard County is the largest without an interstate at 82,752.
Fayette County is the largest without either at 24,277.

Monroe County/Bloomington is an odd one. It was recently on the list of no Interstate nor US Highway, while at the same time is on the western route of the Old Dixie Highway
So it has an old N-S "national" highway, but that never graduated to a US Route nor Interstate. Dixie Highway is basically Old IN 37 thru this area. I guess between Bloomington and Indy Old Dixie Highway is finally graduating to Interstate status, as "New" IN 37 is being upgraded to I-69
The largest county in Utah without an interstate is Cache County (pop. 127,068). Washington County (pop. 171,100) is currently the largest in the state without a US highway, but it was historically served by US 91. There is only one county in Utah has never had any kind of US highway (or interstate, for that matter), and that is Wayne County with its 2,690 people.
Probably Tulare County in California at about 442,000 residents.
PA:
- Cambria County is the most populous without an Interstate.
- Cameron County is the most populous without a US Highway (and also the least populous county in the state). However, PA 120 used to be a US Highway, so this probably doesn't count.
This isn't already a thread? Odd.
North Carolina only has one county without an Interstate or a US Highway: Pamlico, population 13144.
In Wisconsin it's Wood County population 74,000.
In New York that would be my current home base of Tompkins County, population 102,000. Although someone at the City of Ithaca thinks otherwise :biggrin: https://www.google.com/maps/@42.4407435,-76.5106004,3a,40.7y,152.81h,91.6t/data=!3m6!1e1!3m4!1sje27aJbNbk_DP4EfTCC0IA!2e0!7i16384!8i8192
In Minnesota you have to drop all the way to Roseau County (13,500; 54th of 87). We're very well served by US and interstates.
In Michigan it would be Barry County, population 60k.
Lenawee County with 98k would be the largest without an Interstate, but it has 3 US highways.
Louisiana only has 5 parishes without an interstate or a US highway. Washington Parish, the toe of the boot, is the largest at 46,690. That's more people than I would have thought.

It's really the uniform spread of US highways across the state. The Interstates actually go through a minority of counties, but the US highways go everywhere.
Oahu -- Population: 953,207 (2010)
Kings County, NY (a.k.a. Brooklyn). 2.5 million people, no US Routes and never has had one :sombrero:. San Diego County, CA has even a larger population at 3.3 million and also no US Routes, but it had US 80, 101 and 395 in the past. However both of them have Interstates (and so does Honolulu -not Oahu- county in Hawaii), so Tulare may be currently the winner. It, however, had US 99 in the past, so I wonder what is the largest county which has never been served by a nationally-numbered route.

The state's second-most populous county, Hawaii County (the "Big Island") works, with no Interstate or US routes, and a population of about 185,000.
The OP specified population, but Hawaii County is also largest in Hawaii for land area (about 4028 square miles, depending on what Madame Pele has been up to lately). That would be among the larger counties in land area, though it's well behind Alaska's North Slope Borough (over 88,000 square miles, larger than most U.S. states), which also has no Interstate or US routes.
Upstate New York is tailor-made for this thread!
My home county of Monroe (NY) has about 750,000 residents and zero (0) US Routes! We do, of course, have interstates, and many state routes.
Neighboring Wayne County (https://www.google.com/maps/place/Wayne+County,+NY/@43.3479995,-77.6057481,9z/data=!3m1!4b1!4m5!3m4!1s0x89d722fb1aa17da3:0x80be1ddf921081e5!8m2!3d43.2020024!4d-77.010385!5m1!1e1) fits the OP's criteria: no Interstates OR US routes, and a population of 90,064.

And... nothing downstate qualifies, so I guess that's it!
There are 8 qualifying counties out of 62 total counties.
Population-wise, Tompkins is 16th of 62, and the only county with a population over 100K to qualify.
Wayne County is 18th of 62, while Hamilton County is dead last, 62nd of 62.
All population figures are 2018 US Census estimates.
Only one of these in Vermont...Lamoille. None in New Hampshire.
So here's what we've got so far:
California: Tulare County pop. 442,000
Texas: Brazoria County pop. 370,200
Hawaii: Hawaii County pop. 185,000
Georgia: Fayette County pop. 107,500
New York: Tompkins County pop. 102,793
Rhode Island: Newport County pop. 82,888
Wisconsin: Wood County pop. 74,000
Michigan: Barry County pop. 60,000

Illinois: Randolph County pop. 32,546
Missouri: Polk County pop. 31,137
Alabama: Geneva County pop. 26,421
Arkansas: Cleburne County pop. 25,230
Indiana: Fayette County pop. 24,277
South Dakota: Clay County pop. 13,864
Minnesota: Roseau County pop. 13,500
North Carolina: Pamlico County pop. 13,144
Utah: Wayne County pop. 2,690
States with no counties either serviced by a US Route or an Interstate:
New Hampshire, Nevada, Delaware, Connecticut
I'll keep adding to this list once we get more states.
Edit: This list is no longer being kept up to date. See my list on page 2 of this thread for accurate information.
Alabama has 3 counties without a US Route or Interstate Highway:
Geneva: pop. 26,421
Clay: pop. 13,932
Wilcox: pop. 11,670
...so Geneva County would be Alabama's most-populous county in this category, ranked 40th out of 67 by population in the state.
In Illinois,
Counties without either:
Stark
Menard
Crawford
Wabash
Edwards
Randolph
Hardin
Pope
The answer is Randolph at 32,546.

In Minnesota you have to drop all the way to Roseau County (13,500; 54th of 87). We're very well served by US and interstates.
The largest by area today is Lake County, but for counties that have never had a US route, it's Roseau again.
As far as physical size in TX, Brewster is the biggest county (6,193 square miles), and it has no interstates (I-10 would be the closest), but it has US 67, US 90, and US 385.
The biggest in physical size without either interstates or US highways, is Brazoria (yes, again): 1,387 square miles.
Brazoria might be as well as the most populated county to never have had any nationally-numbered routes (be it US Routes or Interstates).

Brazoria might be as well as the most populated county to never have had any nationally-numbered routes (be it US Routes or Interstates).
I think there might be a couple reasons why.
1. Its population has only just recently skyrocketed, after interstates stopped being built en masse.
2. It's in a weird place south of Houston, a city allergic to US highways and Interstates in general.
So it Tulare County the largest by population presently without a US Route or Interstate? Brazoria is the second highest so far from what I've seen listed.

I-45 comes within 2 miles, but none within the county itself.
In Iowa, it's Marion County, with 33,309 population. They did have US 63 and US 163 historically. The county which never had a US or Interstate highway is Appanoose County, with only 12,884.
Arkansas has only 5 counties without a US highway: Yell, Perry, Cleburne, Stone and Izard. A sixth county, Logan, has a tiny loop of US 71 cutting across a corner, and the same is true for Newton County and US 65. Cleburne (25,230) is the most populous of all of them.
There are no counties in Arkansas with an interstate but no US highway. Of the counties with no Interstate, the largest is Garland, which includes Hot Springs.

What? Greater Houston has I-10, 45, 69, and 610, and US 59, 90, and 290 today. That's a ton compared to a place like, say, Phoenix which just has I-10, I-17, and US 60.
I wouldn't say Texas in general is allergic to interstates and US highways, but they certainly do use them sparingly. Just look at DFW's freeways.

The Houston metro is about
7 times more populous than the Rochester, NY metro, yet it has just 1 single 3di serving the area, while Rochester has 3. Houston has tons of freeway mileage, too. They've got quite a few US routes, but not near the concentration of interstates we're used to east of the Mississippi. Houston is much closer to the Phoenix end of the spectrum than the NYC end.
Every county in Nevada has at least one US highway or interstate within its borders. Even tiny 264 square mile Storey County, which is basically the Virginia City mining district, just barely creeps to the north side of I-80 at its northeast corner near Wadsworth and Fernley.
https://en.wikipedia.org/wiki/Santa_Cruz_County%2C_California
Santa Cruz, County California has to be the largest in the Monterrey Bay Area to not have a US Route or Interstate.
Believe Virginia is pretty well covered with only a couple of counties and independent cities without either an interstate or US highway. Of these, Westmoreland County would be the winner with a population of just under 18,000. After the Coalfields Expressway (US-121) is eventually completed in Dickenson County, the counties of Craig, Mathews, Lancaster, and the City of Poquoson would be the other localities left.
Polk County, MO (pop 31,137) is the largest county in the state without the two types of highways. However, State Route 13 is a four-lane divided highway throughout the county, and a freeway through Bolivar, the County Seat of about 10k.

Oh jeez, how could I forget Manassas and Manassas Park :banghead: practically in my own backyard! Guess I forgot that I-66 doesn't actually enter the city limits and just serves the adajent and still highly populated area of Bull Run (commonly reffered to still as Manassas).
BTW, all 3 Delaware counties and all 8 Connecticut counties do have a US highway. In Rhode Island, Birstol and Newport have no Interstates or US Highways. Newport is the largest at 82,888.
For South Dakota, Clay County (population 13,864) is served by three state highways only. I-29 runs north-south less than half a mile past the county line.

Houston was also on US 75 before it was decommissioned in favor of I-45.
Phoenix was also on US 80 and 89 before they were decommissioned, and US 70 before it was truncated west of Globe. In fact, US Highways 60, 70, 80, and 89 were multiplexed from Florence Junction west to the corner of Grand and Van Buren in Phoenix.
Florida: Union County - population 15,535.
It's also home to many institutionalized individuals from the Department of Corrections, which skews the population of the county.

I stand corrected! It does indeed miss by a half mile. So that means Cumberland County, NJ, estimated population 150,972, does meet the criteria of having no US or Interstate routes!

A new thread would be better; this thread has a purpose for including both.
Oregon has Wallowa County.
Kind of an old thread, but since no one did Washington, I'll chip in. The largest county without a US or interstate highway is Kitsap County (pop. 271,473) mainly due to its peninsular nature.
Looks like no one covered Maryland yet either.
Only 3 of 24 counties/independent city qualify: St. Mary's, Calvert & Caroline. St. Mary's is the largest of these 3 (pop. 108,987).
Carroll County almost wins, but I-70/US 40 just barely clips the southwestern corner for a mile and a half near Mt. Airy. (US 140 also ran thru Carroll prior to being downgraded.)

Lane County – pop. 1704 (3rd-least populous county in Kansas)
Greeley County – pop. 1298 (least populous county in Kansas)

Arkansas has only 5 counties without a US highway: Yell, Perry, Cleburne, Stone and Izard. A sixth county, Logan, has a tiny loop of US 71 cutting across a corner, and the same is true for Newton County and US 65. Cleburne (25,230) is the most populous of all of them.
To my previous, Arkansas can have 98% US Highway coverage simply by extending US 266 along AR 22 and US 425 up AR 5. (Perry County will have to figure something else out.)

Here's all the states we have so far again.
Some expected states are near the top, but there are a few surprises, such as Rhode Island.
California: Tulare County pop. 442,000
Texas: Brazoria County pop. 370,200
Hawaii: Hawaii County pop. 185,000
Georgia: Fayette County pop. 107,500
New York: Tompkins County pop. 102,793
Rhode Island: Newport County pop. 82,888
Wisconsin: Wood County pop. 74,000
Michigan: Barry County pop. 60,000
Louisiana: Washington Parish pop. 46,690
Virginia: Independent City of Manassas pop. 41,641
Iowa: Marion County pop. 33,309
Illinois: Randolph County pop. 32,546
Missouri: Polk County pop. 31,137
Alabama: Geneva County pop. 26,421
Arkansas: Cleburne County pop. 25,230
Indiana: Fayette County pop. 24,277
South Dakota: Clay County pop. 13,864
Minnesota: Roseau County pop. 13,500
North Carolina: Pamlico County pop. 13,144
Utah: Wayne County pop. 2,690
States with no counties either serviced by a US Route or an Interstate:
New Hampshire, Nevada, Delaware, Connecticut
Wood County for Wisconsin is wrong. US 10 runs east-west south of Marshfield. I'd have to do some looking to see which county qualifies for Wisconsin, but it's not Wood County.
If your doing both then it's Green County population 36,000. Wood county is still the largest without an interstate at 74,000 on population. Sheboygan is the largest just without a US route at 116,000 in population though it once had US-141 before I-43 came in.
I think Wisconsin's winner (loser?) is Door. #44 out of 72.

Nope Door only has 27,000 in population it would be in 2nd place. Although Green County does have 8 state routes to Door County's just 2.

I counted Big Island for Hawaii because Oahu has the H-Interstates.
Dukes County, Massachusetts has a population of 16,535, with no numbered routes.
By my count, only 3 counties in Ohio qualify, with the largest being Carroll (26,914)

Why might that be the case with Ohio, I wonder? Maybe it's because of the state's abundance of US routes, including several that run diagonal (looking at you, US 33, 35, 42, 52, and 62).

Louisiana only has 5 parishes without an interstate or a US highway. Washington Parish, the toe of the boot, is the largest at 46,690. That's more people than I would have thought.

I counted 6 parishes. Am I overlooking a highway?
Washington
St. Bernard
Plaquemines

Yes, it must be 6 then. I'm not sure which one i wasn't thinking of. Maybe St Bernard because I always tend to think that I-510 goes that far south. It's just LA 47.

define 'large' -- if you mean physically large, i believe jackson county, co has no us highways, and know for a fact no interstates.. and is fairly large physically, but might have like 3 people and a cow living in walden or something.
Fayette County is not the most populous county in Georgia without an Interstate. Forsyth County is. GA 400 is a controlled-access highway in most of Forsyth County, but it doesn't have a red and blue shield, so it's still not an Interstate.
Paulding County and Clarke County also have larger populations than Fayette County, but no Interstates.

US 19 disqualifies Forsyth County.
