Interstates that Barely enter a county or come close to but not enter

[NWI_Irish96]

Hendricks County on I-65 in Indiana. Enters the county, but there is no interchange.

Same with Jasper County in NW Indiana. Although if you were to exit at the famous Exit 220 for Fair Oaks Farms while the interchange itself is in Newton County Fair Oaks is in Jasper County.

You have that reversed. Newton is the county that contains Fair Oaks farms and a short segment of I-65 but no interchanges. Jasper County has interchanges for IN 10, IN 14, IN 114, and two interchanges with US 231.

I-49, when completed, will barely clip Bowie County, Texas, and just Texas in general.

Now that it's official according to the AASHTO spring 2021 thread, I-587 in NC dips into the northern corner of Greene County.

I 80/90 misses St Joseph County, MI, by about 1/2 mile.   

Going across from Toledo, OH to Gary, IN, it doesn't wander too far away from the Michigan line, and the southernmost tier of counties.  In some places, it's measured in yards or feet, not miles.

Your right but the overall idea still stands. Fair Oaks is such a popular stop it's often advertised on the INdot maps. Although not an interstate but as been discussed as a potential future one WI-29 briefly enters Outagamie County before reentering Brown County.

I-35 is only in Washington County, MN for around 3 miles and down in Iowa it comes within 530 ft of Madison Co.
I-94 comes in/ around a mile from Adams County, WI.

WI 29 ticks the NE corner of Outagamie County, WI.  In fact, before the interchange for the NW WI 29/32 split was completed 20-25 years or so ago, its presence in Outagamie County was nearly twice as long.

In skimming county maps for my upcoming trip, I saw that US 2 appears to run right along a county boundary in either Minnesota or North Dakota (I think the former, but not positive.) I wonder how accurate the mapping is.
