What Section of Interstate NOT in your state have you been on the most?

[Hot Rod Hootenanny]

I-55 between Hammond, La & Jackson, Ms. Goes back to when I was attending LSU, and driving back n' forth from Baton Rouge to Jackson concerning field work for my thesis.
PA Turnpike (traveling between Ohio and Philly for family) would be 2nd.

[jp the roadgeek]

For an interstate not in my state: definitely I-90 between I-84 and I-290/I-395. 

[JCinSummerfield]

I-280 in Toledo.  I drive it 1 mile every day to work and home.

[CoreySamson]

I'll do it by state (in order from most traveled to least traveled)

LA: I-10 across the Horace Wilkinson Bridge
AR: I-30, I-440, and I-40 from Texarkana to Memphis
TN: I-40 between exits 14 and 18
MS: I-55 (pretty sure most of it)
AL: I-10 through the Mobile tunnel
FL: Probably I-10 through the Panhandle
NC: I-85 between Charlotte and Kannapolis
CA: Probably I-5 between I-8 and downtown San Diego
SC (and GA): I-85

Other states I either can't remember or didn't use an interstate.

[DJDBVT]

Sections of Interstates that don't enter my state (VT): I-495 between MA 2 and MA 123
Sections of Interstates that do enter my state: I-91 between MA 2 WB and the MA/VT line
I've been on the latter much more than the former for reasons that should be obvious 

[jdb1234]

Easy one for me:

I-75 in Florida between Lake City and Naples.

[Skye]

It would be too easy for me to list one in Kentucky or Indiana so I'm going to skip those states and list mine as I-75 in Tennessee between I-640 and TN/KY. Childhood trips from Cincinnati to Florida and trips as an adult from Cincinnati to Myrtle Beach.

[ethanhopkin14]

This is a tough one.  I might say I-20 between the Louisiana/Texas state line and Shreveport because I made a lot of trips that way as a kid.  But, it might be a toss up between I-10 from the Louisiana/Texas state line to New Orleans and The Texas/New Mexico state line to Las Cruces.  I have taken several trips to Las Cruces plus the ones with points beyond.  also lots of trips to New Orleans plus points beyond. 

[sbeaver44]

Probably I-83 and I-695 in Maryland, and I-86 in New York near Corning.

Still many times but not as many:  I-68, I-81, and I-70 in Maryland.  I-78 in New Jersey.

[DandyDan]

Since I moved here to Mason City, the easy answer to this is I-35 in Minnesota up to the split in Burnsville.

When I lived in Nebraska, the easy answer was I-80 east to Des Moines.

If only states I never lived in were considered, it would have to be I-90 in Wisconsin from Tomah eastward.

[Tom958]

I-24 through Chattanooga. I live near Atlanta and I've worked in Nashville on three separate occasions, plus some incidental travel that way.

[catch22]

The short stretch of I-75 in Ohio between the Michigan state line and the I-280 split in Toledo.  It's part of almost every trip from here in the western Detroit suburbs to points south and east. 

[ctkatz]

easily I 71 from the spence bridge to exit 104.  we took that exit to get to grandma's house.  since then I've taken 71 to get to cleveland and upstate new york and back multiple times.

[EpicRoadways]

I-94 from the MN/WI state line to the WI-29/US-12 interchange in Elk Mound.

[jmacswimmer]

For interstate that also passes thru my state: I-95 in Delaware
For interstate that doesn't exist in my state: A few miles further to I-495 in Delaware

[SSR_317]

For me it would have to be I-17 & I-10 in Arizona. I used to visit Phoenix most every year from 1983-2004 to attend IndyCar races at what used to be known as Phoenix International Raceway (PIR).

If you include FUTURE Interstates, I would say I-11 (US 93), as I made the drive up from PHX to Las Vegas many times. Haven't been there since parts of I-515 officially became I-11, but have driven it all (except the Boulder City Bypass portion). And the last time I was in the area ten years ago I did get to drive (and walk) across the Tillman-O'Callaghan Memorial Bridge.

[Sctvhound]

I-95 in North Carolina. Probably have clinched that interstate 25 times minimum.

[ChiMilNet]

Probably because of traveling to and from college on it so much, I-70 in Missouri (and sadly, it is my understanding that it hasn't been upgraded much since then).

[ET21]

I-90 from IL border to Tomah WI
I-94 from Madison WI to the WI/MN border
I-94 from WI/MN border to downtown Minneapolis

[Nacho]

I suppose counting I-69 north of Bloomington, Indiana would be cheating as it was just SR 37 for the vast majority of the trips I've been on it. Setting that aside it'd probably be I-65 north of Indianapolis. If we further restrict to states I've never lived in, then most likely it's I-295 north of Portland, Maine. As that was formerly designated I-95 I'm not sure whether or not it would still win out if we only count trips when it had the I-295 designation.

[WillWeaverRVA]

Probably all of I-270 in Maryland, and the segment of I-495 between the MD/VA state line and I-270.

[frankenroad]

Hard question to answer, because I have lived in multiple states.  If I exclude all interstates that enter into any of those states, the road most travelled is probably I-86 in NY/PA and I-88 in NY.

If I only exclude interstates that do not enter into my current state (Ohio) it is probably I-96 in Michigan, or I-68 in WV/MD.

What about any section of interstate outside of your state?

That would most likely be I-71/75 in Kentucky from Dixie Hwy to the Ohio River.

[JayhawkCO]

I started thinking today about which highway it would be in a state I've never lived in (I've in 5) and I think it's probably I-29 between I-35 and I-435 in Kansas City.

[allniter89]

K 65 from Mobile, AL to Gary, IN.

[kennyshark64]

Oh, that's easy.  I-80/90 (Indiana Toll Road) between Exit 144 (I-69) and Exit 77 (South Bend), mainly for Notre Dame football.  Even in a pandemic, the campus is great for occasional mental health trips.
