Longest Interstate Clinched NON-STOP??

[CtrlAltDel]

I-4 is the winner for me. It's also the only one I'm sure of.

[dgolub]

I-195 (RI/MA)

Others I've clinched at once:

I-276 (PA)
I-280 (NJ)
I-395 (MD)
I-495 (DE)
I-684 (NY)
I-691 (CT)
I-695 (NY)
I-695 (DC)
I-787 (NY)

Also, if we're counting unsigned interstates, then I-595 (MD).  If we're counting things that are recognized in some places as interstates but signed as state routes, then I-878 (NY).

[epzik8]

Probably I-97. Which isn't impressive at all.

[The Nature Boy]

This was a difficult question but I think that mine would be:

Interstate 93: Canton, MA to St. Johnsbury, VT

[andrewkbrown]

I do I-68 all the time going back and forth between DC and Ohio.

[SectorZ]

I actually realized I had to correct my own facts in this thread, I've done all of (eastern) 84 in one sitting from Sturbridge to Wilkes-Barre this summer.

I just remembered I-865 is its own Interstate now, and it would be awkward to do that one without clinching it non-stop. And I've done it at least once.

[DevalDragon]

All of interstate 57, at least once, southbound.

You drove all 386 miles of Interstate 57 without stopping once? You are hardcore!

[Darkchylde]

Before the Arkansas and Missouri segments opened up, I pulled off a clinch of I-49 (between Shreveport and Lafayette) in one shot with the Civic in '06. With that no longer counting, I-12.

[mariethefoxy]

did I-684 before and I-290 (Worcester Freeway) without stopping.

[Bickendan]

I-210 California, back when its eastern end was at the Kellogg Interchange with I-10, CA 57 and 71. Technically, it's still valid as the 210 extension is CA 210, not I-210...
Can't count I-205 California because of a construction detour.
I-505
I-405 Oregon
I-705
I-210 Louisiana
I-510
I-115
I-515
I-675 Michigan
I-580 Nevada pre-Carson City extension

I'm sure a pattern's noticeable, lol

[jbnati27]

I'm fairly sure I've done I-68

Others less impressive 3dis:
I-270 (OH)
I-670 (OH)
I-540 (NC)
I-495 (NC, soon to be defunct)
I-240 (NC)
I-126 (SC)
I-475 (GA)
I-471 (KY-OH)
I-405 (CA)

[vtk]

Others less impressive 3dis:
I-270 (OH)

I'm curious as to why exactly you would drive a full circle around Columbus without exiting even once.  Did you forsee this thread?

Interstate clinching's a hobby.  If anything, the only place in the Universe it isn't surprising that someone would drive the entire loop is on this forum.

I-580 California from I-5 to Oakland, before 580 was extended to Richmond.

[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.

That's not a clinch.

   You are correct. Despite being told to "READ CAREFULLY" right in the OP, apparently I did not read the OP carefully enough and misunderstood the premise of this thread. I humbly acknowledge my error. (I still think 230 miles non stop is pretty impressive though.)

   Probably my longest "clinch" following the rules of the OP would be I-280 (CA) at 57 miles.

[Avalanchez71]

I-12
I-68
I-73
I-97

I-335 in Kansas is like this.  It goes through zero towns between endpoints.  I have, however, stopped at a median service area at least once.  Speaking of this, how many of y'all have clinched I-238 without doing it in one shot–i.e. getting gas at Mission Blvd or stopping at the Jack-in-the-Box (not on Glenoaks, where they keep the pools of old poison gas and obsolete germ bombs) for lunch.

I forgot I-238 on my list. Wow. I suppose it doesn't count as being part of CA 238? lol

238 is defined as one road for the purpose of California's legislative route definitions, but I-238 is particularly distinct (as one needs to turn off from Route 238 north to reach I-238 west, and vice versa from I-238 east to Route 238 south).

I-680 southbound (71 miles)
I-880 southbound (45 miles)

I  have certainly done them both Northbound non-stop. If you were of a mind to, you could certainly do SB I-680 and NB I-280 back-to-back non-stop. With only a brief interuption by a few hundred meters of surface streets and the Bay Bridge, you could then do SB I-880 in the same non-stop trip.
I-580 has a routing (Central Valley to Marin via Oakland) such that it is unlikely to be traversed non-stop except by someone deliberately trying to accomplish the feat, but, for all I know, some truckers might do it every day (but isn't there a truck restiction on some part of it in Oakland?).

Yes, there's a truck restriction on 580.  There have been times it was lifted, such as when 880 was closed post-Loma Prieta.  Anyone who's clinched 580 in a truck should raise their hand.

There are people who drive between the Central Valley and Marin, and for them 580 would be the obvious way to go.

[paulthemapguy]

I-76 (west) ought to be a popular one.  And the new I-41 which I accidentally clinched last weekend heh

I'm assuming that you didn't drink anything (including water) for prior to making that stretch.
