As some of you may recall, a few months ago I made a post about highways that went through two or more cities or towns of the same name in different states. Well, I figured that I might ask the same question, albeit for counties instead of cities.
I know for a fact that both Kansas and Missouri have a Saline County, and I-70 goes through both of them. Farther east, I-70 also goes through Clark County in Illinois and Ohio, as well as Montgomery County in Missouri and Ohio.
I-55 goes through Madison County, IL (Metro East) as well as Madison County, MS (north Jackson suburbs).
I-35 serves both Franklin County, KS and Franklin County, IA. Somewhat closer to home, US 50 goes through Johnson County, KS (KC suburbs) as well as Johnson County, MO (Warrensburg).
What other Interstate and US highways are there that traverse multiple counties of the same name along their path? I'm sure there are numerous examples of that throughout the country.
I-90: Rock County, MN and WI
I-90: Jackson County, SD and MN
US 41, I-94 - Lake County, IL and Lake County, IN.

US 1 goes through RichmondCounty, GA and Richmond County, NC.
I-95 (and US 1): 3 Middlesex Counties (NJ, CT, MA). Also Essex County NJ and MA.
I-75 goes through Hamilton County, Ohio; Hamilton County Tennessee and Hamilton County, Florida. I-75 also goes through Monroe County, Michigan and Monroe County, Tennessee. I-75 also goes through Crawford County, Michigan and Crawford County, Georgia.
Fun fact: I-75 is in Crawford County, Georgia for less than a quarter of a mile.

US 1 goes through RichmondCounty, GA and Richmond County, NC.
If you wanted to throw independent cities into the mix, you could also add the City of Richmond.
I-94 goes through Jackson County, Michigan and Jackson County, Wisconsin as well.

In that case, I'll take the easy one and say that US 50 goes through Fairfax City and Fairfax County, Virginia.

As does US-29.

Technically, Middlesex County in CT hasn't existed since the 1960s. US 1 definitely went through it when it was a county. Not sure if 95 was commissioned through there before Connecticut got rid of counties.
As a Nutmegger, it blew my mind when I learned that other states had areas that weren't part of an incorporated town or city.

US 36: Marion County, IN and MO
Too bad US 60 runs too far North upon entering Virginia from West Virginia, otherwise it would have hit both Craig County and craIG county.
Back when the original US 331 existed, it only existed in Escambia County, despite running through two states. Of course, they are two different, neighboring counties by the same name in different states. To this day, US 29 (which absorbed US 331) still runs through Escambia County, FL and AL.
US-31 surprisingly has no repeat counties. It barely misses Shelby County IN but goes through Shelby County AL.
However, I-65 qualifies as it clips the corner of Shelby County IN then goes through Shelby County AL.
I found another (kind of) pair for I-75, as it passes through Miami County OH and Miami-Dade County FL
Although West Virginians don't think of it this way, I-64 is technically routed through both Fayette County, Kentucky and Fayette County, West Virginia (that part is on the West Virginia Turnpike). I-64 also runs through Wayne County, Illinois and Wayne County, West Virginia. Additionally, I-64 runs through Jefferson County, Illinois and -uhh- Louisville. In a quirk of fate, I've been through all of these after taking a detour from Centralia, Illinois down US-51 to catch an tiny extra slice of I-64 when I was working in on a project in Western Illinois back in the mid-1980s.
US 30 travels through both Allen County, Indiana and Allen County, Ohio.
US 89 travels through Teton County, WY and Teton County, MT. And if you count the implied segment through Yellowstone, it also hits both Park County, WY and MT.

CT's counties may not have any government anymore, but that doesn't mean they don't exist as far as I'm concerned. Some federal agencies still use them - for example, the National Weather Service issues alerts by county, and the census bureau still has them for statistical purposes (although that may not last too much longer since the state is now proposing to use the 9 councils of government as county-equivalents). It appears CT court districts also correspond to the county lines, so even in a governmental sense they aren't just random lines on a map now.
