Longest Interstate Clinched NON-STOP??

[frankenroad]

I-68 multiple times
I-88 (NY) - possibly - although I used to like to stop at the diner in Unadilla, which is no longer there.
I-86 (CT/MA) - now part of 84, so not sure if it counts.

I-290 (MA)
I-395 (CT/MA)
the two above should be one continuous route, IMHO.
I-270 (MD)
I-684 (NY/CT)
I-275 (MI)
I-275 (OH/KY/IN) - right after the last segment opened in the late 70s
I-271 (OH)
I-471 (KY/OH) - many times
I-264 (KY) - by accident -- this was pre-GPS and I was given bad directions and never found my exit and went all the way to the end.  The person giving me directions had left out the critical step of taking I-64 - the exit they named was off 64 not 264.
I-865 (IN) - probably the shortest
I-395 (VA/DC)

I-195 in NJ (about 34 miles)

Same as me... I have done the entire Jacksonville beltway (295)-- inner loop-- when the east beltway was finally signed, however i fail the challenge.. I entered and exited from Blanding Blvd(SR 21)

LGMS428

Like many others, my longest nonstop clinch is I-4 (from west to east). I have also clinched I-57 in a day, but I did get off the road for gas.

[paulthemapguy]

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

Just to be clear, this post was meant to indicate that I-41 is my answer.  Longest Interstate clinched with no stops whatsoever. All my other non-stop clinches are probably 3dis, most notably I-294.

I-275, 475 and 675 in Michigan.

Despite having driven all of I-696, I doubt I've ever done it's entire length in one shot.

I can't remember whether I did I-196 non-stop.  If so, that would be my longest.

Then there's these - I-375, I-194, I-296.  Those were grueling.

You'd be hard pressed to even see another vehicle at times on I-375.

I-83 from Baltimore to Harrisburg it's only like 60 miles tho.

Doesn't matter.  It's not the length, it's the function.

That's what she said!

Serious answer, I want to say Sacramento-Wheeler Ridge on I-5, for about 300 miles.

I feel like I-5 is substantially longer than 300 miles...

Not an Interstate but CA 99 from Sacramento south to Wheeler Ridge is all freeway and every bit the 300 miles that I-5 is.  I've done that one in a single sitting....again not an Interstate, but that damn thing has so much traffic moving fast sometimes you might average 80 MPH the entire way.

I-5 is almost 1,400 miles long, not 300. I don't know of any vehicle that would let you clinch that non-stop!

Diesel Passat?

I'd still recommend stopping to get some sleep or switch drivers, though...

Not to mention restroom stops.

Meh, nothing a couple bottles couldn't handle.

If one's a passenger, sure; but if one's the driver...

That's where the skill factor comes in.  Figure on that 1,400 miles on I-5 you might optimistically be able to drive that in 23.33 hours of you maintained a speed of 60 MPH.  To be conservative for comfort reasons figure "potty break" would be between 2-3 hours.  That being the case someone would need to carry at least 12 twenty ounce bottles to make the journey in full. 

Now all those assumptions are based of not having a need for a bowel movement.  Also the bottle method would generally only work for male drivers. But the again race car drivers manage to do stuff like this...I'll leave it to your imagination as to how.  I guess it would all come down to how much you really wanted that non-stop clinch with the properly prepared vehicle.

Depends on the driver!!!

They make 'adapters' for gals.

[PHLBOS]

Keep in mind, per the OP's criteria, non-stop means no stopping even for potty/bathroom breaks.

Certainly at least I-88 in Illinois. I am pretty sure that is it.

[Roadgeekteen]

I-295 D.C.

[TheHighwayMan3561]

I figure it has to be I-494. I can't think of any other candidate at this point.
