Counties in your State without a State Route

[Hunty2022]

Is there any counties in your state/province that don't have any State Routes? This excludes County Routes, Secondary Routes, or any route in Texas that doesn't have the word Texas at the bottom and a number on top .

For Virginia, Page County and Essex County lack a state route, though both have two US Highways.

[SD Mapman]

Nope, none in WY either.

[Scott5114]

I don't believe there are any in Oklahoma.

[jlam]

None in Colorado, but there are a few with only state highways (no Interstates or US Routes)

In Massachusetts, we have Dukes and Nantucket Counties, Martha's Vineyard and Nantucket respectively.

The only two counties in all of New England without one.  Pretty sure we can also eliminate NY, NJ, PA, DE, and MD. 

[webny99]

None in NY, and I'd be pretty surprised if there's a lot elsewhere in the country aside from oddities like islands, etc. That's because a state route system that doesn't serve all counties in the state really doesn't really make much sense.

Speaking of islands, Rhode Island has Block Island, which has no state routes, but it's also not it's own county.

[Max Rockatansky]

None in California, Arizona and Nevada.

In Hawaii, only Kalawao County doesn't have any numbered and posted state routes. But AFAIK Hawaii DOT helps the state department of health (which with the National Park Service co-administers the county) with any major maintenance of its small and isolated road network.

In Alaska, the state DOT maintains most of the road network. But the small subset that has (usually) posted route numbers with one or two digits, in addition to five- or six-digit internal inventory numbers, doesn't include anything in the Aleutians East, Lake and Peninsula, Bristol Bay, Northwest Arctic, Kodiak Island, Yakutat, Sitka, and Wrangell boroughs, or the Aleutians West, Kusilvak, Nome, Bethel, Dillingham, Hoonah-Angoon, or Prince of Wales-Hyder census areas.

I'm pretty sure that there is at least one state highway in all 83 Michigan counties.

TX pretty much legislated the possibility of this ever happening out of existence in the very early days of numbered roads in the state.  They wanted at least 1 numbered road to connect a county seat in 1 county, to a county seat in a neighboring county.  So even in the farthest-flung, sparsest-populated counties in TX, there's at least 1 numbered road.

Cross-posting some edge cases:

Massachusetts has two counties with no signed state routes (Dukes and Nantucket), but both have state-maintained roads.

Technically, San Juan County in Washington.  It is only served by SR 20 Spur... and that is only if you count the ferry landings as part of the route, even though it never actually travels onto any of the Islands, but the ferry route is part of the State Route.

[Dirt Roads]

All of West Virginia's 55 counties have state routes, and I'm pretty sure that each of the county seats are served by a state route.  Almost all of these counties also have a U.S. Route in addition to the state routes.

Only 1 State Route

• Lewis (plus 1 Interstate route plus 4 U.S. Routes)
• Morgan (plus 1 U.S. Route)

Only 2 State Routes

• Ohio (plus 2 Interstate routes plus 2 U.S. Routes)
• Pendleton (plus 2 U.S. Routes)
• Roane (plus 1 Interstate route plus 2 U.S. Routes)
• Taylor (plus 3 U.S. Routes)
• Upshur (plus 3 U.S. Routes)

No U.S. Routes

• Pleasants (3 state routes)
• Summers (1 Interstate route plus 4 state routes)
• Tyler (5 state routes)
• Webster (3 state routes)
• Wirt (4 state routes)

[NWI_Irish96]

No Indiana county has fewer than 3 state highways.

[flan]

Billings County, ND, has no state routes within its borders, but I-94 and U.S. 85 go through the county.

No county in Minnesota is without a state route–Cook County is the closest, only served by MN 61.

[US 89]

There is no county in Utah with fewer than two state routes or three numbered highways. That would be Daggett, which has US 191, SR 43, and SR 44.

All but one have a US and/or Interstate, too. The only one that doesn't is Wayne, and it has four state routes (12, 24, 72, and 95).

There are five more counties that lack a US route, but do have an interstate because the US route was decommissioned in favor of it. Those are Beaver, Iron, Washington (US 91 to I-15), Tooele (US 40 to I-80), and Morgan (US 30S to I-84).

San Juan County, WA only has a ferry route that is part of the state highway system (SR 20 Spur), so it has/lacks a state route depending on how you want to county ferries and bannered routes.

The fewest number of routes for a normal county is 2 (Wahkiakum and Skamania are tied).

[mgk920]

None here in Wisconsin, either.

Since all highways are actually state highways, including Interstate and US highways, no county in America, short of Alaska and Hawaii would have 'no state "routes', with the exception of of some urban areas, where surface roads might be posted for continuity, like NYC, and even then there are two exceptions: NY 9A(in reality a 9xx route) and NY 440 which is a freeway, but not an Interstate.

And don't forget San Juan County, too.

Kenedy County, Texas only has US 77 and Concho County (also in Texas) only has US 83 and US 77. Unless you count FM routes.

[wanderer2575]

I'm pretty sure that there is at least one state highway in all 83 Michigan counties.

Correct, although two or three are just barely.

[bulldog1979]

I'm pretty sure that there is at least one state highway in all 83 Michigan counties.

Correct, although two or three are just barely.

I come up with four counties that each have just two:

• Keweenaw: US 41 and M-26
• Lake: US 10 and M-37
• Montmorency: M-32 and M-33
• Oscoda: M-33 and M-72

Those last three, all in the Lower Peninsula, essentially have a single north—south and a single east—west highway, while Keweenaw has a single central highway with a loop off it.

None in AL

Holy shit, it's Otto Yamamoto. I feel like I just saw a celebrity...
