Longest Interstate Clinched NON-STOP??

[Mapmikey]

I've clinched a few 2dis with the OP criteria: I-12, I-17, I-82, I-86(w), I-97

The longest is I-17 at 146 miles

[DandyDan]

It depends on whether you consider I-88 in Illinois clinched if you end up taking the I-294 north exit instead of going straight onto I-290.  If not, I believe it is the Iowa/Nebraska I-680, at 43 miles.

[OracleUsr]

I-97.  I-275 Knoxville, TN

[NWI_Irish96]

I-88(IL) 141 miles

Also I-41 (176 miles) but before it was actually called I-41 so I guess that doesn't count.

[SectorZ]

395 in MA/CT for me would be the longest, with bonus points for I-190 in MA well over a thousand times with my old Fitchburg to Worcester commute.

[pianocello]

I was going to say I-24 overnight on a bus (school trip to Florida), but then I remembered we stopped at the welcome centers at the TN/KY border both ways.

It should be I-88 Illinois, but I'm not sure if I've ever gone without stopping in DeKalb. I suppose that makes my longest I-294, then. 54 miles.

[roadman]

I've clinched I-476, I-99, I-190 (MA), I-195 (MA/RI), I-290 (MA), and I-295 (MA/RI) in single non-stop trips.

[SP Cook]

I-68 113 miles.

[cappicard]

I-470 in Topeka (less than 14 miles long) and in Lee's Summit (16 3/4 miles long). Both are within 67 miles of each other. Probably the closest unrelated 3di's with the same number.

I-670 in Kansas City (less than 2 miles long)

I-635 in Kansas City (12 miles long)

[cappicard]

I-335 between Topeka and Emporia.  I remember when this stretch of the Kansas Turnpike didn't even have a highway number until '87.

[KEVIN_224]

If it's completely in one pass, no stops or exiting? No 2-digit interstates for me. I-84 is the only one I've completed, but never all at once since A- I live within 3 miles of it and B- Sturbridge, MA to Dunmore, PA is quite a hike!

If talking 3-digit interstates?

I-278 (NY/NJ)
I-290 (MA)
I-291 (CT and MA)
I-293 (NH)
I-295 (ME)
I-384 (CT)
I-676 (PA/NJ)
I-684 (NY/CT)
I-691 (CT)

[Doctor Whom]

I-68, shortly after construction was completed.

[akotchi]

I-470 in Topeka (less than 14 miles long) and in Lee's Summit (16 3/4 miles long). Both are within 67 miles of each other. Probably the closest unrelated 3di's with the same number.

The I-395 segments (and I-695 segments, for that matter) in Baltimore and Washington are closer together, at 35 miles, give or take.

[hbelkins]

I-68 several times.

Also I-99 and the eastern I-88. Can't count I-66 because of the temptation of the Haymarket Sheetz.

Can't remember if my clinch of I-12 was non-stop or not.

I've also done I-97 but it's hardly the longest.

I've clinched a number of 3di's nonstop, including a complete counterclockwise circumnavigation of DC on I-495.

I stand corrected.

[bzakharin]

I-195 in NJ for me too, though only Westbound

[1995hoo]

Either I-4 or the Delaware/New Jersey I-295. I'm not sure about I-4, but I know I've done this on I-295.

I-68 comes close, but the only time I've been all the way to the west end, we made a toilet stop at the West Virginia welcome center and that violates the thread rules.

[Thunderbyrd316]

   Personal Best: December 1998, I-70 from Clifton Exit 37 to Kipling Street Exit 267. Total 230 miles non-stop. In a 1974 Mercury Cougar XR-7.

   

[bassoon1986]

I-12 many times going from Louisiana to Florida, and I-49 many times from Shreveport to Lafayette. I would have I-45 but for the stop at Buc-ee's in Madisonville.

[kphoger]

I've also drove I-135 from Salina to Wichita once.  That's about 95 miles.

Even though I live in Wichita, I've never gone from endpoint to endpoint on I-135. That would require coming down from I-70 and then continuing on the Turnpike towards Oklahoma (or the other way round). I've never had reason to do that.

My longest would have to be I-88 in Illinois, continuing onto the Eisenhower towards Chicago, but that's been a good 17 years now.

I've also one-shot clinched I-35W through Fort Worth eight times, I-35W through Minneapolis once, I-335 in Kansas once or twice, and I-635 around KC countless times. I probably did I-27 in Texas with my dad back in high school a couple of times, but my memory of fuel and meal stops back then is fuzzy.

That's not a clinch.

[PHLBOS]

I-295 in NJ; about 67 miles.

[wphiii]

This is tough for me; I'm a big Stopper. I like to, at the very least, keep my blood flowing every couple of hours. My longest true non-stop clinch is probably I-68.

Edit: though that wouldn't have been the first time I'd clinched the road, so I'm not sure if that's what the OP was going for or not.

[jwags]

Would I-99 in New York count? Technically it isn't connected to I-99 in PA.

[doorknob60]

Depends on if I'm the driver or the passenger. If passenger counts, I-82 would be the winner for me (143 mi). If we're talking me as the driver, besides I-82 (which I've driven about 98% of myself but not clinched), I've only really driven on long 2dis. You're not gonna clinch I-84 (W), I-90, or I-5 in one non-stop sitting. I've only been on I-86 (W) as a passenger so that one's out.

So, for me as a driver, that leaves 3dis. I-205 comes to mind, but I've never driven it end-to-end in one sitting, so that's out. I-405 (OR), only time I use that is to access US-26/Sunset Highway, so that's out. So that leaves the measly short ones: I-105 (OR) - 3.5 mi, and what I suppose is the winner, which I also happen to clinch non-stop nearly every day, I-184 (3.6 mi). Yeah, pretty lame winner  But add up all the times I've clinched it and it's a large number .
