Longest Interstate You Haven't Been On

[TEG24601]

I-40.


Been on 90, 80, but have never once traveled on I-40.  The one chance I had, at age 5, my parents were driving only on US Routes, until we got to I-70.

[cenlaroads]

I-80, followed by I-70.

[ozarkman417]

I-10.
Second place would be I-25 but I was on it for a half mile in Downtown Denver.

[TheGrassGuy]

I-40

[deathtopumpkins]

I started to say I've never been on I-10, but then remembered New Orleans...

So for me it's I-15, and I don't anticipate that changing any time soon.

As for US highways, it's US 87. Though several longer ones I only have a small concurrency on an interstate.

I-95.  Believe it or not I have yet to see the Atlantic Ocean in person.  On the other hand the Pacific Ocean gets seen regularly and when the Cascadia Subduction Zone quake breaks loose, I will see the ocean come to within a stone's throw of my place.  Good thing that I live on the highest point of land for this end of town!

Not difficult when you live on the opposite coast, to not see the other ocean.

I have only seen the Pacific Ocean once in person, in 2000.  I made sure and dipped my bare feet into it so that I could say that I have been "in" the ocean!

I have been on I-5.

For the Great Lakes, I have dipped my feet into Lake Erie and Lake Ontario, and have done full body swimming in Lake Michigan.

Have not yet seen Lake Huron or Lake Superior in person.

[Rothman]

Huh...Great Lakes:

Touched Superior, swam in Huron, boated on Erie, but I don't think I've actually touched Michigan or Ontario.  Seen them and been right up to the water, though.

[Brandon]

Longest ones I haven't been on include I-16, I-19, I-27, I-78, & I-82, & the eastern I-84.  Of these, The eastern I-84 is the longest.

Since then things have changed.  It's now I-16.

I've only seen the Pacific Ocean twice, Hawaii and Southern California, both in the past decade. Never been to any other western state.

The furthest west my regular (at least once per year) travels take me is Texas.

Very off-topic...

I've been swimming in Lake Michigan @ Chicago (IL), the Indiana Dunes, and Manistique (UP Michigan)
I've been swimming in Lake Erie @ Rondeau Prov. Park (ON)
I've been swimming in the Pacific Ocean @ Newport Beach & some other beach (CA) and San Francisco (Nay)
I've been to the beach at the Gulf of Mexico but didn't go swimming because of riptide @ Galveston (TX)
I've never been in the Atlantic Ocean, although I have been on a ferry across the Nantucket Sound.

I don't recall ever having been to Lake Superior, Lake Huron (unless you count I-75 over the Straits of Mackinac, or Lake Ontario.

I've been in the Atlantic (Virginia Beach, Outer Banks) and Pacific (Honolulu) Oceans, along with the Gulf of Mexico (Corpus Christi / Padre Island). Have yet to go inside the Great Lakes.

Edit to add: Also have been to Pensacola Beach and Gulf of Mexico there. Very nice beaches, some of the best I've ever been to.

How about surfing ... where have you surfed?  As in board surfing.

I have in the Atlantic Ocean, Melbourne FL area, in the 1960s as a teenager; never was very good at it.

Nowhere else ...  The Atlantic and Pacific have many good surfing places, and (don't laugh) in certain weather Lake Superior and Lake Michigan have enough surf to make it feasible.

I have been to the Gulf of Mexico, Captiva Island near Fort Myers, FL.

[Rothman]

At least in Superior, WI, half the surfers end up hypothermic.  Lake Superior is cold.

[Beltway]

Lake Michigan even in the summer and even at the southern end is cold.

I remember as a teenager going in an inch at a time, took about 10 minutes before I would be in up to my neck, at the beach in Chicago.

I-95.  Believe it or not I have yet to see the Atlantic Ocean in person.

It could be worse - I'm much, much closer to the Atlantic, and I haven't seen it in person either.

Huh...Great Lakes:

Seen and been in both Lake Erie and Lake Ontario at multiple different locations.
Seen the other three Great Lakes, but not touched them (at least not that I can recall).

It's funny, visitors often question whether Lake Ontario actually is the ocean.

[KEVIN_224]

I have only been within sight of Lake Michigan at ground level maybe twice. I never went into it.

Longest N/S interstate I've never been on? Probably I-85. I-89 is the one I'm missing in New England.
Longest E/W interstate I've never been on? Probably I-94. I've been in it's median in Chicago via the CTA Subway though. Otherwise, it'd likely be the current I-86 in PA and NY.

Oregon surfing is done with wet suits.  Guess what that makes you look like to a shark?  FOOD!  Seals are a protected species here even though they gobble up fish like crazy and in due turn the sharks swarm in to eat the seals and on occasion a surfer gets a not so friendly encounter.  A friend of mine who also went to the same high school as I did was surfing here on the South Coast and had a chunk of his board removed by a shark.  This was noteworthy to make the news in USA Today when I was living in Utah during the mid 90's. 

Glad he survived the encounter.  "Death by shark" is not something most people think of but you do have to watch out over here for just such a thing happening.

It'd have to be I-94 for me.

Been on I-90 in the Cleveland metro, I-80 on the Ohio Turnpike, I-40 in Barstow & between Greensboro and I-95, I-10 in the Los Angeles metro & between Pensacola and Houston, I-70 between I-81 and the Pennsylvania Turnpike, I-95 in many different sections between Miami and New York City, and I-75 in the Atlanta metro.

Being more specific...

For east/west - I-94
For north/south - I-25

Been on I-35 between San Antonio and Dallas, I-15 between San Diego and Barstow, and I-5 between Wheeler Ridge and San Diego.

[Beltway]

Oregon surfing is done with wet suits. 

Wintertime in Florida the water is cold enough that they usually use a wet suit.

Granted it is far about the hypothermia level, but it is cold enough to be rather uncomfortable.

[HTM Duke]

As far as north-south interstates go, mine would be I-15.  I-5 is a very close second, given the short difference in total length between the two.

In terms of east-west overall, it would be I-44.  However, if I were to break down I-84 into two segments given the gap between them, then the western half of I-84 would be the winner.

[TheGrassGuy]

For US Routes, it's US 60.
And for NJ State Routes, it's NJ 47.

[Roadsguy]

I almost would've said I-90, the most boring answer to this question, but I was almost certainly on at least a small part of it (albeit not driving) as a kid during a trip to Niagara Falls, so that would leave I-10.

[roadman]

For me, that would be Interstate 10.

[amroad17]

I-82.
