The reason I put a star next to Bay County, FL, is because we're trying to determine if larger-populated Clay County truly doesn't include a piece of I-295.

A lot of these are on track to be served by Interstates soon: Jonesboro, AR will get I-555, Cass County, MO will get I-49, Carson City, NV will get I-580.

Sussex passed Kent sometime in the late 1980s.

NORTH CAROLINA: Union (201,292) I 485 parallels the county line.

For Alaska, the largest county equivalent not served by any of Alaska's unsigned Interstates is Juneau City and Borough (population 31,275).  That borough doesn't even have road access to the rest of Alaska or North America (and won't get it in the foreseeable future), just auto ferries.

Forum member ethanman62187 insists that VA-28 is to become I-366, thus remedying that situation.

I'm gonna call it a night. I'll finish this later.

Clay County FL has  population of 190,865  and no interstates... right now there isnt even a limited access freeway in the county.  If the First Coast Outer Beltway is ever build it will have a Limited Access  Highway... parts of it are now a Super 2 with traffic lights      

[rawmustard]

MICHIGAN: Lenawee (99892)--includes Adrian

I would never have guessed Lenawee would have almost 13,000 more than Grand Traverse (ultimately the second-most-populated county here without a freeway of any sort), but then Traverse City (14,674) must only seem larger than its population indicates. (Adrian's population is 21,133, also higher than I would expect.)

This was a bit of a surprise for me, but in Ohio it's Columbiana County coming in with 107,841 people.  I-76 misses the NE corner by not much.  Honorable mention goes to Fairfield Co with 146,156 and about a mile and a half of I-70. 

[luokou]

In Oregon, it's Deschutes County with 157,733 residents, which includes Bend.

[Revive 755]

A lot of these are on track to be served by Interstates soon: Jonesboro, AR will get I-555, Cass County, MO will get I-49, Carson City, NV will get I-580.

You forgot Bloomington, IN, which is likely getting I-69 over its NIMBYism.  Owensboro, KY, is trying to get and will likely receive at least a spur off future I-69.

Carbondale, IL, would likely have one had the supplemental freeway between Marion and East St. Louis not been cancelled.  Dubuque, IA, also could have gotten one or two interstates had the freeways once planned for the US 61 and/or US 20 corridors in Iowa not been downgraded to expressways.

Somehow, I missed Delaware. I'll fix that.

While that is true, at this very moment, those communities are not served by an interstate. Once that happens, Garland County, AR (Hot Springs), Cole County, MO (Jefferson City) and Nye County, NV will be next in line for their respective states.

As far as Clay County, FL, my atlas shows an extremely small sliver of I-295 does dip into the county. Is there anyone either in the area or familiar with that area confirm this?

I wondered about that too, so I checked a map on the county's website. It appears as though the county line runs literally right next to part of I-295, but none of the road itself is inside the county.

LOUISIANA: Terrebonee (104,503)--includes Houma

Well...when I-49 South gets finished sometime in the 24th Century, Terrebone Parish will be off the list.  

Who would then be next in line in Louisiana?? Vermillion Parish (Abbeville)?? West Feliciana Parish (St. Francisville)?? Pointe Coupee Parish (New Roads)??


Anthony

[golden eagle]

Yes, it would be Vermilion Parish, population 58K. Had Katrina not happened, St. Bernard Parish would be next in line. St. Bernard had a pre-Katrina population of about 67K. Now, it's around 33K.

[mgk920]

Right now for Wisconsin, it is Outagamie County (my home county) - 176,295 (2010 USCensus).  Once the proposed US 41 promotion to full interstate happens, the largest Wisconsin county without an interstate will be Wood County - 74,749 (2010 USCensus).

From my experience, the Duval/Clay County line, and its signs, are roughly half a mile from I-295.

The border is the ROW near the junction US 17 in Orange Park... The border was originally a bit father south but once 295 was built in the lat 60s early 70s the border was moved to the edge of the ROW so there wouldnt be a sliver of Duval south of the Interstate.  There is a one neighborhood between NAS Jax and 295 that has an Orange Park Mailing address but it is in Duval County

IOWA: Dubuque (93,653)--includes namesake Dubuque

US-20 in Iowa is pretty darn close, and it probably will become an interstate (no idea of number) if a southern bypass is built and IDiOT gets their act together between Dubuque and Rockford.

The reason I put a star next to Jackson County, IL is because I'm trying to determine if a small section of I-80 does cross into upstate Kendall County. If no interstate passes through Kendall, then it would be the most populated in Illinois without an interstate. Same with Bay County, FL, if Clay County truly doesn't include a piece of I-295.

If you go to mapquest and zoom in really, really close, you will find that I-80 does in fact go into Kendall county.

IDiOT, act, together?  Surely you must be joking!

I-80 does indeed go through Kendall County.  Even has the sign on the westbound (but not eastbound) side.  Half of Exit 122 (Ridge Rd) is in Kendall County.

[Scott5114]

I figured Enid would be the result for Oklahoma. Maybe US-60/412 should be upgraded to I-735.

True. I prefer to call it wishful thinking.
