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

[jdb1234]

For me:

2di: I-16
3di: I-675 (GA)

[Rothman]

I've traveled at least some segment of all 2dis.*

The closest completely untraveled 3di looks to be I-478, the Brooklyn-Battery Tunnel (which was also my closest untraveled segment of any Interstate when I just updated the thread on that topic).  I'm also missing all of I-878 near JFK.  I don't believe either of those is signed.  To get a signed 3di that I'm missing, I think we need to go down into Maryland, where I've never been on I-795.  That looks to be about 370 miles from home.

*Edit: Since some are making this distinction, I'll point out that my travels on I-11, I-22, and the southern I-87 were before they were signed as those routes but on the same pavement, best I can tell.

How can you have been on a route before it existed?

I guess that it may depend on your Travel Mapping goals - are you clinching "numbers", or are you clinching "stretches of asphalt"?  IMHO either way is fine.  Depends how you treat any routes that are re-numbered or re-routed.

No, clinching routes is the only acceptable approach.  This is the Way.

I live near San Diego, and the closest Interstate I haven't been on is I-380 in San Bruno, which is less than two miles long and more than 450 miles away. After that, I think it's probably I-215 around Salt Lake City, over 630 miles away.

Agreed.  I say I haven't been on Interstate 11 even though I have driven it but it was 2015 (minus the Boulder City Bypass that wasn't complete).  I will have to return to clinch I-11.

I never counted I-14 to my tally until I drove it, despite having driven that stretch of US-190 so many times I lost count.  Now I have driven I-14 so many times I have lost count.

For 2DI, it's likely I-49 for N-S interstates and I-44 for E-W interstates. It's possible I-96 is closer in straight line distance.

For 3DI, I assume it's I-535, with I-172 ready to take over that title when (and if) I go to Duluth in August.

[Roadgeekteen]

3DI- probably I-393
2DI- I-86

[Concrete Bob]

2 DI - I-86 in Idaho.  Though I have been at either end travelling on both I-84 and i-15.

3DI - I-380 in San Mateo County.  Though I have crossed I-380's path by travelling on both US 101 and I-280.

[pderocco]

This is a lot less interesting if you don't tell us where you are to begin with.

[Ted$8roadFan]

I-280 in New Jersey
I-86 in New York: was last on it when it was NY-17.
I-88 in New York
I-99 in Pennsylvania: was last on it when it was PA-26.
I-68

It can be derived from the information given, generally.

This thread, unlike most others, uses your current location as a reference point, not where you live. If you're on a road trip, your answer will probably be different.

[signalman]

2di: 26 (I have driven the section that was formerly 181) Edited answer: 30
3di: 480 OH

Heh.  The level of pedantry on this board never fails to amuse.

[elsmere241]

Probably a couple of 3dis in the Bronx or Queens for me.  As far as 2dis, I'd have to think really hard and pull out the atlas or something.

[jmacswimmer]

The ones I came up with are closer by than what I was expecting:

2di: I-85
3di: I-195 (VA)

[DesertedHighwayz]

As far as I know, the closest I have never driven on is I-195 in Richmond, I may be incorrect. If I am incorrect, I-564 in Norfolk, VA.
2-digit closest is probably I-77 (which is pretty far away)

In that case I-75 is the only 2di that I've crossed without ever going on.

[doorknob60]

I've been on I-182 (~300 mi) and I-105 (~440 mi) many many times as a kid (I've lived in Eugene, Springfield, Pasco, and West Richland), but I've never driven on them myself as an adult, so I don't count them driven on Travel Mapping.

I've never been on I-115 in MT at all, ~420 miles away, so that's the closest interstate I've truly never been on.

The closest 2di I've never been on is I-70, ~475 miles away. Though I have crossed I-70 in both Columbus, OH and Frederick, MD.

I've also not been on I-94 or I-25, which came to my mind first, but I-70 is closer.

[Dough4872]

Closest Interstate I haven't been on is I-380 in Pennsylvania.

[cstp3103]

For highways I've never driven personally:
2di: I-89 (110 miles away)
3di: I-295, RI/MA (30 miles)

For highways I've never been on, period:

2di: I-78 (174 miles)
3di: I-384, CT (81 miles)

I'm assuming I had been on I-89 as a small child as I had gone to Vermont with my family a few times, but it was (slightly) too early for me to be paying attention to which roads I was on.

Update: I ended up driving the entirety of I-384 less than a week after this was posted, as well as a segment of I-295 on the same trip. This means that now the closest 3di I've never driven on is I-395 in CT (51 miles away) and the closest I've never been on at all is I-495 on Long Island (107 miles as the crow flies).

[Streetman]

There's a stretch of a 3di in Connecticut that most of its residents including myself have never been on: I-684, which is mostly in NY with just a tiny stretch grazing a corner of Greenwich. Probably no reason anyone going from any place in CT to anywhere else would use it.
Closest 2di for me is I-87.

[tmoore952]

I was heavily into travel in the 1990s, not so much since after I got married. Some highways have appeared since then.

My 2di answer at that time would have been I-16 in Georgia. But since then I-73 has appeared in NC and that would be my answer now.

3-di - never been a big fan of driving many of these since they are usually very short and one has to be careful at the termini especially if you are terminating in the middle of a big city. But some have been very useful to me (I-276, I-476, I-287, I-684, I-180 and I-380 (latter 2 in PA)). Since I am in DC now I am certain my 3-di answer is I-195 in Richmond.

EDITED - removed incorrect statement I made about I-73.

[PColumbus73]

2di: I-10

3di: I-795 (NC)

[flan]

From Twin Cities
2di: I-74 in Davenport, IA
3di: I-380 in Waterloo, IA

From Fargo
2di: I-74 in Davenport, IA
3di: I-229 in Sioux Falls, SD

I-74 just barely beats out I-88 in Illinois and I-76 in Nebraska
