Longest US Highway that you have not been on

[Rothman]

Looks like US 278 for me, too, but I need to check to see if I touched it in the Tupelo area.

[WillWeaverRVA]

US 20.

[Mapmikey]

US 285 for me

[US 89]

Looks like mine is US 212. To be honest I'm surprised I made it that far down the list.

Some of the longer ones barely count, though. I've only been on US 52 and 81 because I exited onto them once from an interstate to get gas. US 14 I have from its very brief concurrency with IL 43. Maybe a couple other close calls but those are the big ones that come to mind.

Well, I did.  So, that takes me to US 18, which I probably did not drive in the Madison area...

Only if you were on the Beltline.

Excluding concurrencies: US 20 (concurrency with I-39)

Including: US 2, followed by US 12

I haven't been on US-70 (#7) since before I was old enough to drive, on a camping trip with my dad in junior high.  But I was old enough to remember it, so I'm not going to count that as my answer.

I may have been on US-1 (#8) at some point during a childhood vacation to New England, but it was long enough ago that I don't remember much of where we went.  So that's what I'm going with.

If I've been on US-1, then my answer would be US-11 (#23).

Like many others, US 60.

[Big John]

US 50

[kphoger]

Like many others, US 60.

...which is so strange to me, considering I've driven approximately 375 miles of it, in six different states, over the course of multiple years.

I'm similar to you. 368 miles.

It's a dispute between two routes. If the implied routes through Yellowstone are counted, then US 20. If not, then US 6.

[formulanone]

US 191, but that may change next week.

Now I haven't been on any section of US 95.

For me, it is the western segment of US 2 based on Wikipedia.

[adventurernumber1]

I was initially going to say US 20 (the longest US Highway of all), but then I got to thinking I might have actually been on the unnumbered part of the road at some point while in Yellowstone. Should this not be true (or count), there's a miniscule possibility I may have been on part of the route in either Boston or the Chicago area, but my memory is too fuzzy, and the chance is almost 0.

But if I have in fact been on US 20, then the longest US Highway I haven't been on would likely be US 60 -- unless by chance I have been on a short portion via a detour in downtown Louisville (but the memory fails me) -- if that is true, then the longest US Highway I haven't been on would be US 12 or US 2 (neither segment).

US-50

[Bruce]

US 6, though I have crossed it a few times in Ohio and Connecticut.

I recently drove the westernmost segment of US 20, so that's one off the bucket list.

[dlsterner]

We've had this thread before, back in 2019.  I'll just link my answer from then; it is still the same answer today.

Longest never driven would be US 12, but I have crossed it.  Never driven and never crossed would be the western US 2.

[Flint1979]

US-87

[Hobart]

US 6 passes through my town, US 30 passes to the south, and US 20 passes to the north. Because the south suburbs of Chicago have an absurd number of US Highways on them, many of the longest routes are just part of a daily commute, or a road I have to take to buy something off of Craigslist.

A lot of the other routes I've barely been on. US-40, 64, and 70 I've only been on because they share a bridge with I-55 in a city I've been on I-55 through. The only portion of US 60 and US 62 I've been on is the weird concurrency between them where they enter Illinois on one bridge, intersect US-51, and immediately leave the state again.

Working down the list on Wikipedia, the longest route I haven't been on is US-84, because my family doesn't travel east and west as far south as US-84 runs.

You should link the old thread.

I'll have to take a closer look at the mileages and concurrencies of some of the western routes, but off the top of my head, my winner is probably 395. My trip across the Golden Gate Bridge when I was in San Francisco a couple of years ago took care of 101 for me.

Somehow, that thread wasn't one of the search results when I attempted to search for it using this thread's title (and similar to the other two thread's title, except for US routes of course). If a mod sees this, feel free to merge this thread into the other one.
