I was often wondering which US route transits the most counties in a single state? So far I have come up with US 1 in Florida transiting 13 counties. However US 90 does 16 in the Sunshine State and you can say 18 if you count two of them twice as US 90 enters Holmes and Washington counties two times.
Is there any other roads that go through more than these?
I would guess that the answer is in Texas somewhere. US-83, the longest US highway in the state, goes through 27 counties.
In Iowa, it's a tie between US 6 and US 18, with 13 counties apiece.
I forgot that Texas, despite it being rural has small area counties unlike its neighbors in the west that have large counties due to sparse population.
A surprising 2nd place may be US 64 in North Carolina: 25 counties

Can US 9 in New Jersey get an honorable mention for running through 10 of the 21 counties?
US 60 gets 23 counties in Kentucky. US 62 gets 20. US 68 gets 19.
How many counties and independent cities does US 58 get in Virginia? I'd think it would be a lot.

If I counted correctly US 58 gets 25 counties and independent cities...

US 87 goes through 28 counties in Texas.
I count 26 for US 67 in Texas. Third place so far, with the top three in Texas.
Currently in Nevada, US 95 hits the most counties of any other US highway--8. Considering there's only 17 counties in Nevada, that's pretty good. A related interesting fact is that US 95 serves the county seat of every county it traverses, except Lyon county (which it only clips the unpopulated eastern tip of).
Formerly, Old US 40 (now mostly supplanted by I-80) hit 9 of 17 counties.
In California, the easy winner is: US 101: Los Angeles, Ventura, Santa Barbara, San Luis Obispo, Monterey, San Benito, Santa Clara, San Mateo, San Francisco, Marin, Sonoma, Mendocino, Humboldt, Del Norte = 14 counties. Historically this also included Orange and San Diego for 16.
99 probably had more though (excluding when the 99W/99E splits existed): Imperial, Riverside, San Bernardino, Los Angeles, Kern, Tulare, Fresno, Madera, Merced, Stanslaus, San Joaquin, Sacramento, Yolo, Sutter, Butte, Tehama, Shasta, Siskiyou, for 18 total.
In Indiana, US 421 enters 14 counties northbound and 13 counties southbound. US 231 enters 13 counties both directions.
US-41 goes through 22 counties in Georgia.

That is an interesting point. US 95 actually travels through almost half of the state's counties which means in another sense it is going through the most counties.
However, US 13 in Delaware goes through all 3 of its state's counties. It, unfortunately, does not go through all 3 county seats, but it goes through 2 of them. Hey 2 out of 3 ain't bad.

No US routes go through all five counties in RI. In fact, two of the five (Bristol, Newport) do not have any US routes in them at all. US 1 does pass through the other three (Kent, Providence, Washington).
Michigan's highest is US 31, with 14 counties (just barely entering Cheboygan before its northern terminus), followed by US 23 and US 131 at 13 each. I don't think any past route has gone higher. US 27 may have also been 14 if it entered Emmet County, which I don't think it did.
US 98 goes though 20 counties in Florida, and seems to brush Gilchrist County (northbound) (https://www.google.com/maps?hl=en&ll=29.5907,-82.925534&spn=0.010636,0.038581&sll=42.244785,-75.06958&sspn=5.098736,9.876709&t=m&z=15&layer=c&cbll=29.590866,-82.925931&panoid=CVc7Tr_BdOsReH_GOFWrdQ&cbp=12,307.25,,0,16.66) for 21 in total.
I believe that US Route 76 wins in S.C. It goes through 13 counties.

Michigan's highest is US 31, with 14 counties (just barely entering Cheboygan before its northern terminus), followed by US 23 and US 131 at 13 each. I don't think any past route has gone higher. US 27 may have also been 14 if it entered Emmet County, which I don't think it did.
At various times, US-27 and US-31 both went into the UP, but only in Mackinac County. And US-27 would have been in Emmet County on the approaches to the Mackinac Bridge. That makes 15 for each of them.
US 31 in Alabama goes through 14 counties.

I wondered about US 460, but it only gets 23 by my count (though you would have to travel through a 24th, but Mercer County, WV isn't within Virginia, so not counted)

101 goes through all their county seats with the exception of San Benito County. 13 out of 14 ain't bad.
US 51 goes through 15 Mississippi counties. US 49 also goes through 15 counties, though some are due to an east/west split from Yazoo City to Tutwiler.
I see that US 98 in Florida goes through 20 counties, which is awesome considering that Florida has 67 of them. Granted, the route runs within Florida for 670 miles.
US 90 hits 14 of Louisiana's parishes (crossing Jefferson and Orleans parish lines twice) and US 190 clinches 11. They are the only 2 to cross the state lengthwise and traverse through the "boot."

I
was counting Mackinac for US 27:
- Branch
- Calhoun
- Eaton
- Ingham
- Clinton
- Gratiot
- Isabella
- Clare
- Roscommon
- Crawford
- Otsego
- Cheboygan
- Emmet
- Mackinac
...but you're right about US 31. I forgot it once entered the UP. Oops!
US 67 in Arkansas traverses 14 or 15 counties
US 65 goes through 14
US 40 goes through 10/24 counties in Maryland (counting Baltimore City as a county): Garrett, Allegany, Washington, Frederick, Carroll, Howard, Baltimore, Baltimore City, Baltimore again, Harford, Cecil.
In Oklahoma, US 412 goes through 16 counties. US 62, US 64, and US 270 each go through 15.
