What's the Closest Interstate to you that you Have Never Been on Any of it?

[freebrickproductions]

I-169 (KY) is probably the closest one I have not been on any part of.

For 2dis only, it'd be I-44 for the closest that I ain't been on.

[Sapphuby]

I-255 (IL) is the closest 3di I've never touched, and as for 2di, I-74 is the closest one I've never even gotten close to.

[NWI_Irish96]

Overall: I-380
2di: I-49

My closest overall is now I-480 in Ohio.

[TheStranger]

The closest 3di I've never been on is I-105 in Eugene, and the closest 2di I haven't been on is (western) I-84 in Portland.

[I-55]

Overall: I-280 (OH): 92 miles
2di: I-43 & I-41: 188 miles

I have been on the Ohio Turnpike at I-280's southern terminus, and I have never been to Wisconsin

Closest Interstate Overall I Haven't Traveled On - I-110 (TX) - 633 miles
Closest (Kind of) 2di That I Haven't Traveled On - I-35W (TX) - 752 miles
Closest 3di (Unsigned) That I Haven't Traveled On Nor Intersected - I-315 (MT) - 786 miles
Closest 2di That I Haven't Traveled On Nor Intersected - I-14 - 878 miles
Closest 3di (Signed) That I Haven't Traveled On Nor Intersected - I-474 (IL) - 933 miles

Looks like when it's designated, I-344 in OK will be the closest now at 626 miles.

2di: I-70 (possibly I-68)

3di: I-395 (VA/DC)

[Great Lakes Roads]

2di: I-99 (PA/NY)
3di: I-165 (KY)

[Scott5114]

I'm roughly equidistant from both I-17 and I-210 in CA.

[FrCorySticha]

2di: I-86(w)
3di: I-215 (Utah)

[Roadgeekteen]

Somehow never answered this one:

3 digit: I-391 (I think)

2 digit: I-99

[-- US 175 --]

I-37 would be my closest guess.

[Quillz]

Probably I-19. I've been on: 5, 15, 17, 25 at various points in my life. But I don't recall ever driving on any part of 19. Been on: 8, 10, 40, 80, 84, 86, 90. I've never been on I-82, but it would be farther away from me than I-19.

[JayhawkCO]

I'm probably one of few people on this forum whose first interstate clinch was I-19.

[BJ59]

I am in DFW. I have not been on I-369, in Texarkana. After that, its probably I-69 in the Houston metro

[ran4sh]

From my North Georgia location: I-12 for 2di, I-140 TN for 3di

From my Central Illinois location: I-88 for 2di, I-155 IL for 3di

Edit - I've never been on either I-88 but obviously the one in IL is closer to my home in IL.

[Hunty2022]

Edited for today:

2di: I-70 (possibly I-68)

3di: I-270 (MD) (possibly I-381 VA)

[74/171FAN]

I want to say right now that it is I-481 in NY or I-291 in CT.  Probably the former for another year or two.

[cockroachking]

I-291 and I-391 in the Springfield, MA, area for me.

I-878 in Queens for unsigned routes.

[thspfc]

Either I-88 (IL) or I-280 (IL/IA)
