What section of Interstate in your state have you been on the least?

[Roadgeekteen]

If you haven't clinched every interstate in your state (like me), that would be your answer. But if you've clinched them all, which part have you been on the least?

[Max Rockatansky]

For some reason I don't hit I-710, I-605 and I-105 very often.

[sprjus4]

Haven't been on I-77 between I-81 and the West Virginia state line, I-66 between US-29 and US-17, nor I-381.

I've hit all the other interstate highways in their entirety in the state, including all of I-64, I-81, I-85, and I-95, plus the other segments of I-66 and I-77. Additionally, all of the 3di's except I-381 - I simply have no reason to drive on it.

[NWI_Irish96]

There are a couple segments of I-469 that I've only been on once.
I-64 west of IN 69 only twice.

[Roadgeekteen]

Here are the one's I haven't been on:

I-190
I-291
I-391
Most of I-91 (except the MA 2 multiplex)
Parts of I-93 near Boston
I-195 (except the MA 24 multiplex)
Much of I-495

I'll order all Ohio's interstates from my most driven to least. Note that this includes Ohio's section only, otherwise I-70 would be my #1 due to me living in St Louis for some time.

1) I-71
2) I-275
3) I-75
4) I-74
5) I-270
6) I-70
7) I-670
8) I-471
9) I-675
10) I-470
Past this point, these are interstates I've only been on once or twice, so they're about equal on how often I use them.
11) I-90
12) I-271
13) I-76
14) I-80
15) I-77 (only on concurrency with I-76)
16) I-480 (only on concurrency with I-271)
17) I-475
18) I-280 (took a detour onto 280 just to drive on the Skyway bridge)
Past this point are the interstates in the state I've never been on.
19) I-277
20) I-490
21) I-680
Though not an interstate, I haven't been on the Ohio Turnpike at all.

I'm surprised that you've made it onto I-90, I-80, and I-76 but never the Ohio Turnpike.

[doorknob60]

For me it's I-15 between Idaho Falls and Dubois, never been on that at all. In that general region I'm going to either be on US-20 or ID-22 on any road trip from Boise, unless I need to stop somewhere else along the way, which is not very likely (eg. stopping in Idaho Falls on the way to Butte for whatever reason).

Honorable mentions:

• I-15 between Pocatello and Tremonton I've only been on once, very unlikely to change (since going to Utah I'm almost always going to take I-84).
• Most of I-90 I haven't driven myself (I've been a passenger on it twice), and living in Boise that's not likely to change soon. Eg. if I am driving to Missoula I'm going to take US-12 or US-93, not I-90.
• I personally avoid I-86 when I can in favor of US-20 or I-84 (unless my destination is Pocatello or continuing on US-30), but I still end up on it on occasion (eg. avoiding winter weather on US-20 driving to Idaho Falls), I think I've been on it 3 times now (only once as the driver).

I'm surprised that you've made it onto I-90, I-80, and I-76 but never the Ohio Turnpike.

Yea only been on the free sections of those 3. The Ohio Turnpike runs in a somewhat NW-SE alignment, which isn't really helpful for someone like me living in the southwestern portion of the state. I got I-76 and I-80 by convincing my dad to use the I-71/I-76/I-80 routing instead of the standard I-70/I-78 on a trip to NYC, as I was bored of the PA turnpike at that point. For I-90, it goes in a SW-NE direction east of Cleveland, sort of like a continuation of I-71's alignment, so it helped us on a trip to Niagara Falls, and maybe Boston if we drive that far in the future.

[TheHighwayMan3561]

I've been struggling to come up with a concrete answer that I'm happy with, but in general it's I-90 between Austin and the US 14/61 split near La Crescent, and I keep zeroing in specifically on the section between MN 16 and US 52. Due to better options from the north to get to destinations along/in the orbit of I-90 (US 52 to Rochester, US 61 to Winona, US 63 to Stewartville, US 218 to Austin), there's little reason for me to get on 90 unless I'm up to something specific; I've also now clinched everything in southeastern Minnesota, so there's no further reason for me to use 90 either.

I've clinched the Interstates in VT (not super hard to do), but there are three stretches I've done only once:
I-89- Exit 21 (VT 78) to Canadian border
I-91- Exit 11 (US 5/WRJ) to Exit 26 (VT 58); Exit 28 (VT 105) to Canadian border

If you haven't clinched every interstate in your state (like me), that would be your answer. But if you've clinched them all, which part have you been on the least?

I believe that I have driven every section of Interstate in California that can be driven (not necessarily the last couple meters on I-5 before the Mexican frontier). I am not sure that I have clinched I-215 and I-8 while they were called by those names. I have driven the fewest number of times on the eastern sections of I-8.

[wanderer2575]

I-69 between Flint and Port Huron.  Close second would be I-69 between Lansing and Flint.

[WillWeaverRVA]

In Virginia, I haven't been on I-81 south of I-581 and north of the southern end of VA 37, I-64 west of US 11, or I-77.

[jmacswimmer]

I think the only section in MD I haven't driven myself (though I have been a passenger) is the brief <1 mile piece of I-295 heading north into DC from I-95/495 by National Harbor.

[GaryV]

Much of I-69 from Marshall to Port Huron.

Honorable mentions (I have been there but not lately and not often):
I-96 west of Grand Rapids
I-196 from Holland to Benton Harbor
I-94 west of Kalamazoo

[OCGuy81]

Interstate 82 in Oregon. 

[gr8daynegb]

Only I-535 in Wisconsin have I yet to drive on 

[US 89]

I have driven every mile of interstate in Utah. The only segment I haven't been on more than once is the bit of I-70 over the San Rafael Swell, between US 89 in Salina and US 6 west of Green River.

[sprjus4]

Haven't been on I-77 between I-81 and the West Virginia state line, I-66 between US-29 and US-17, nor I-381.

I've hit all the other interstate highways in their entirety in the state, including all of I-64, I-81, I-85, and I-95, plus the other segments of I-66 and I-77. Additionally, all of the 3di's except I-381 - I simply have no reason to drive on it.

If I'm answering the question based on where I have driven... only been on I-85 and I-95 between Petersburg and US-58 once, and it was specifically to clinch. I have no reason to logically drive those roads. Also I-66 between US-17 and I-81.

[Big John]

I-94 between Eau Claire and Elk Mound.

[tigerwings]

Never been on 76, 490, 670, 675, 680 in Ohio. 75 and 475 the most. 70, 71 and 270 several times around the east side of Columbus. Only on the others once or twice.

Been on all freeways in Michigan and Colorado

[Ned Weasel]

Definitely I-70 west of I-135/US 81.

[ctkatz]

granted, I may have been on this part of highway when I was younger and just don't remember, but I 24 between the western kentucky parkway and I 65 I don't recall being on.  the only sections I have only been on once are I 75 between I 71 and 64, I 64 east of 75, and I 24 west of the purchase parkway.  note: I am not counting I 69 as it is not connected to any other part of constructed 69 or the parkways redesignated as 3di interstates.

[gr8daynegb]

Only I-535 in Wisconsin have I yet to drive on 

Have driven I-39, 41, 43, 90, 94, 794, 894 their whole distance in WI so really just a few miles to complete the whole thing(for right now)
