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

[gr8daynegb]

I-90 from WI/IL border to the I-69(frm US 27) exit with I-80/90 in Indiana

[I-55]

Out of State: I-75 MM 61-110 (I-70 Vandalia to US-33 Wapakoneta, OH)

If it's simply the segment of Interstate I've been on the most outside Virginia, it's easily I-395 in DC between the 14th Street Bridge and the 12th Street exit. I used that road to commute to work for many years and in non-pandemic times I use it regularly to go to Caps games.

If it's the Interstate that doesn't exist in Virginia that I've been on the most, it's likely I-270 in Maryland. I don't know that for certain, but I'm positive I've been on I-270 more often than unsigned I-595. Less sure about I-895 in Baltimore, which is a road we used on trips to New York when I was a little kid and the Fort McHenry Tunnel wasn't open yet.

(Edited to fix a typo.)

Gotta be a toss up in North Carolina between the I-40/85 overlap and I-95 south of US-64.

If it's a road that doesn't enter Virginia at all... than either I-40 between I-85 and I-87, then I-87 for its entire current length.

[SkyPesos]

I-71/75 in KY between I-275 and OH border.

I read the OP differently than others it appears.  I read it as "which interstate that doesn't exist at all in your state have you been on the most", not which stretch outside of your state.

I'll answer this one too: I-64 between MO 340 (exit 19B) and MO 141 (exit 22), but that was from when I used to live in the St Louis area. If excluding states that I used to live in too, along with all interstates that go through those states, then it's I-465's southern loop between I-70 and I-74 for me. If excluding 3dis too, then I-65 between I-865 and IN 38.

One of the following:
I-4 in the Orlando area
I-75, I-280, and I-475 in the Toledo area
I-80/90 (Toledo to Sandusky)

From going to Myrtle Beach almost every year to visit my maternal grandmother, mine would be most of I-95 in both Virginia and North Carolina. Between Dumfries (my paternal grandparents' old exit) and Carmel Church (the entry point for those coming in from 301 via 207), I have been on it less frequently, because when we went with our dad he preferred 301 to avoid Northern Virginia's congestion. After my parents split, my mom preferred 95 because she didn't like the endless traffic lights on 301. Additionally, my dad would take 295 around Richmond and Petersburg while my mom would take 95 through them.

My exception for North Carolina is the 13 miles between I-74 and the South Carolina line. Leaving 95 at 74 was always hassle-free for us, especially once the new interchange opened.

1. I-495, Virginia
2. I-66, Virginia
3. I-95, Virginia
4. I-395, Virginia

[SEWIGuy]

I-94 Illinois

Ditto

[davewiecking]

The few feet on I-495 between the MD/VA state line and the GW Pkwy exit.

[mgk920]

I-94 Illinois

Ditto

Same, most specifically the non-Tollway parts of I-94 north of the Stevenson (I-55).

I 65 from Mobile to Gary. We had regular loads from Armstrong to Shitcargoland.

[GaryV]

If we are talking about a section of Interstate that is outside MI, then I-75 in OH.
If we are talking about an Interstate that is not in MI at all, it could be I-80, various sections.  Or maybe I-465 or I-469 in IN.

[zzcarp]

Since I moved to Colorado in 2006, it would be easily be I-80 from the east terminus of I-76 (W) near Big Springs, NE to Des Moines, IA.

[wanderer2575]

Going with the "which stretch outside of your home state" interpretation, mine by far would be the whopping 3.4 miles of I-75 between the Michigan/Ohio line and I-280 in Toledo.

Going with "which interstate that doesn't exist at all in your home state," that would be I-80 in Ohio between I-280 and I-76.  If plans hold, I will be driving it again this coming Saturday.

[jp the roadgeek]

I-91 between the CT line and the MA I-291.

[bwana39]

Clearly I-20 in Louisiana. I-49 in Arkansas and Louisiana is passing it soon.

Outside my region, Probably I-40 in Arkansas or Maybe I-20 in Mississippi.

[hbelkins]

Out-of-state portion of interstate that enters your state: I-64 east of the KY/WV state line to varying departure points (WV 10, US 60/29th Street, WV 193, I-77). In my youth, it was I-75 south of the state line to Knoxville.

Interstate that does not enter your state: I-77 or I-79 in West Virginia, I-81 in Virginia or Tennessee, or I-26/former I-181 in Tennessee. At one time, I-640 in Tennessee would probably have been the leader.

[sparker]

If limited to Interstates that don't enter CA, my present residence, it would be the western I-84.  Disclaimer: I lived in Portland for 4 1/2 years in the early/mid '90's while attending grad school.  If the OP refers primarily to sections of any Interstate existing outside of CA it would definitely be I-5 in OR and WA, partially travels relating to the aforementioned academic stint and partially business and recreational travels to the Seattle area before, during, and after my Portland residence.

[SEWIGuy]

NOT in my state for an interstate that doesn't enter Wisconsin....

I would guess I-80 between I-294 and I-65.

[kphoger]

My guess is I-57 between Mount Vernon and Ina, IL.  Either that or between Ina and Whittington.

I used to drive a delivery route in that region, and almost every single day's route would have used that stretch of highway, no matter what other routes I drove that day.

[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?

[KCRoadFan]

I-35 between Des Moines, IA, and Minneapolis, MN (visiting relatives in Minnesota).
I-70 between Troy, IL (I-55 junction east of St. Louis) and Columbus, OH (family trips out east).

Beyond Columbus, the route depends on where our destination is:

• Going to places in NY State or New England (Buffalo, Boston, etc.): I-71 north to I-271 to I-90 east near Cleveland.
• Going to Philadelphia: I-70 east through Washington, PA, to the Turnpike at New Stanton.
• Going to DC: I-70 east to Washington, PA, then to I-68 in Maryland (either via I-79 south to Morgantown or US 40 through Uniontown to Keyser's Ridge); east through Cumberland to I-70 at Hancock, then through Hagerstown to pick up I-270 at Frederick).

[dkblake]

I've lived in four different states (MA/NY/OH/VT). Not counting the interstate sections of those states, I would probably say I-95 in CT between Bridgeport and New Haven.

If we're doing the more restrictive definition and not counting any interstates that pass through any of those states, then probably either I-696 between I-275 and Telegraph or the I-69/I-94 multiplex in Port Huron.
