So I got to thinking the other day about what state I have been to, but have not visited for the longest time. I came up with New Jersey in 1983. (Though I was just across the Hudson from it last year.)
So how does this apply to highways? Like New Jersey, most of these date back to my childhood when I would visit my mother's family out east. These are reasonable guesses.
2-digit interstate: I-87 (Business trip to upstate New York in 1994)
3-digit interstate: I-287 in New York (1984. Drove this from I-95 to I-87 when we drove back to the midwest via Niagara Falls.)
US highway: US-9 (1981-ish. Drove from Tarrytown to West Point. I don't believe I have been on it since, though I have crossed it at least once.)
For 3di it's I-680 in California, I haven't been to the Bay Area in more than 2 decades. 2di is probably I-17, from the same trip.
2di: I-4 in 1986
3di: I-395 in 1985
US: US 56 in 1987
2di: I-5 in 2018
3di: OR-WA I-205 in 2013
US: US 18 in 2008

2dus: US 46*, in 2013
2di: I-82, in 2016
* probably the oldest
US 201 which I was last in 1991 for US Route. Probably some far flung 3d Interstate in New York in the 1993-95 era.

3di: I-680 (CA) Jan 1976

I-55, by virtue of not having been to Illinois since 2007.
2DI I-93 near Manchester NH 1990
(honorable mention: I-44 which, except for the formerly concurrent part on the Poplar Street Bridge and the extension that I took when it used to be I-70 in Downtown St. Louis, I haven't been on since 1980)
3DI I-475 Georgia 1985
US probably US 4 near Concord by a hair over US 202, both in 1990
2di: I-4, 2008 (though did pass it in 2019)
3di: I-189, 2005
US: No idea.
2di: I-H1, 2005
3di: I-H201, 2005
Mainland 2di: I-64 in VA, 2009
Mainland 3di: I-710 in CA, 2007
2DI: I-4, last traveled on in 2009
3DI: I-126, last traveled on in 2009 or 2010, not sure
2DUS: US 92, last traveled on in 2009
3DUS: US 192, last traveled on in 2009
Wow, you are all making me feel old. There were a lot of contenders for this thread, but here's my best answer:
Interstate: I-16 (1987)
US Route: US-129 (1983)
Interstate: Either I-65 or I-59, depending on our routing we took on a trip to NC in 2007.
US Route: Apart from anything that was multiplexed with the above routes (US 280, perhaps?), my concrete answer would be US 29, which I haven't been on since 2012 or 2013.
Interstate
2DI: I-75 (1986). I-4 one day shorter
3DI: I-190 NY (1990). I-290 NY about 15 minutes shorter
US: 192 (1982). US 58 one day shorter.
Interstate: Probably I-30. Last time I was on it was in 2011 when I was visiting friends that had moved. I-820 would be the last of the 3dis.
US: Same trip, most likely US 81 and 287. Friends lived near Decatur, TX at the time.
I’m pretty sure all of mine are from a trip to Seattle in 2010...
2di: I-82
3di: I-405 WA
2dus: US 97
3dus: US 395
Quote from: US 89 on August 02, 2022, 11:54:13 PM
3di: I-405 WA
Depending on how soon you return to WA, the I-405 you remember will have long since changed. HOT lanes have necessitated a complete rebuild of the corridor, with the north half already done and the south half underway.
2DI - I-80 - 2001 (crossed it last November)
3DI - I-580 - 2001
US - US87 - 2004
Off the top of my head, it would be I-4, US 92, and US 192. Last time I was in Florida was 1978.
Sticking with since I've been driving...
2di - I-29 (2000)
3di - I-195 (ME) (1990)
2dus - US 91 (1997)
3dus - US 160 (2013)?
In terms of what I have logged in TM (>99% certainty that I've traveled it), I guess it would be I-696 (MI). I don't remember exactly when, but it was around 2004. I'm pretty sure every 2di I've been on, I've been on since 2017. I'm drawing a blank on I-83 but that might be 2016. If so, that would be it.
US Route would be US 8, last traveled in 2012.
I haven't been on I-5 since 2005, before I was 2 years old.
I try to revisit routes before too many years pass, but its been since September 2006 for I-82 and OR/WA in general. For 3di's was last on I-105 in Oregon in April 2005. Maine's 3dis are June 2005.
US Highway, likely US 201 in Maine from June 2005, edit US 199 in Oregon in April 2005.
The last section of Interstate I had not been on since childhood was I-90 between Buffalo and I-86 near Erie. Finally took that again last August; was on it previously in August 1989.
The last sgnificamt section of Interstate I did solely at night was I-84 between I-380 and Newburgh, NY in October 2004. I have at least some photos of every other Interstate otherwise and I only have 88 miles of I-81 and I-781 left to clinch...that's not including the AK and PR legislative ones.
I haven't been on the western I-76 since a family vacation to Colorado when I was 12. This was in 2002.
The only time I've been on the Puerto Rico unsigned Interstates was over the Labor Day long weekend in 2002. I'm pretty sure I've been on part of every other Interstate (including Alaska's unsigned Interstates) since then.
US routes, I'm not sure.
