Last previously-untraveled road you were on?

[Max Rockatansky]

Old Stage Road south of San Juan Bautista.  On the State Highway front CA 116 a couple weeks back.

That said, the last previously untraveled road I've been on that is a state-equivalent route is A-1604. I had already been on the westernmost 10 km (6 miles) or so (about 1/5 of the way), so the rest of it was new for me. Never again unless it is renovated. Map of what I had not done previously.

Updating this. I was to say a newly opened section of A-21 freeway, but then the OP specified...

Has to be a state maintained route, not necessarily posted, but included in the state's inventory.

... and since this section is neither maintained nor included in Aragon's inventory as it is owned by the (sovereign) State, I have to exclude it. Clearly this doesn't take into account the situation in Europe, where there are many nationally-owned roads (in the USA the equivalent would be a Federal road). The last road I had not traveled before to really qualify for this thread is A-1241 near the Catalonia border.

My family's trip to visit relatives in Louisville for Thanksgiving added many such segments of I-68, I-79, I-64, I-75, and I-71–even the new segment of US 219 between Meyersdale and Somerset–but the last of these untraveled sections on the way home was I-70 from Columbus to New Stanton.

Including roads which I drove for the first time but had been on previously as a passenger, the segment of the Blue Route between the Schuylkill Expressway and the PA Turnpike is the most recent road that I myself drove for the first time just two weeks ago.

I would say a 'clinch' of WI 318 late last summer.

[Ben114]

For me it would be a clinch of MA 181 on Saturday (the 11th).

[formulanone]

Ohio Route 18, today.

[oscar]

The short, separate Mt. Harmony segment of MD 765 south of Annapolis, in early December.

For my last new whole route, the short VA 148 connector between I-77 and US 52, in late November.

My updated and now much clearer answer: US 441 Business in Franklin, NC, this past weekend.

I got my second-to-last freeway in Hampton Roads over the weekend: VA 164.

Question re Hampton Roads:  Is it possible for a civilian to clinch I-564?  Since it provides access to the naval base and then dead ends, I have always assumed that it ended at a place that only active military could access (or retired military if going to the PX).

The surface highway (VA 337) at the west terminus of I-564 is accessible by civilians.

None of the interstate goes onto the base, it's fully 100% accessible. The northern interchange provides gate access, and there's gate access on the northern end of the freeway, but that's beyond it's terminus and it intersects VA-337 before that.

Even the recently completed Intermodal Connector is accessible to the public, though doesn't go anywhere. You can take it to the end, then easily turn around and head back without reaching any gate. I did this after it opened.

Clinching M-227 in September.

[sbeaver44]

If I understand its routing correctly, NJ 165 in Lambertville.  I was following NJ 29 North from US 1 to US 202.  Another time years back, I had done US 202>NJ 29>NJ 179>PA 179>US 202>PA 32, but that shouldn't have had me actually on NJ 165...I think.

[debragga]

New mileage of US-165, as well as LA-2, LA-443, LA-15, and LA-550. All were a few weeks ago, same trip.

[sparker]

Last fall coming back from a quick trip to Eugene, OR to talk with a potential client, I decided to look up an old colleague who had semi-retired from the electronics industry to -- of all things -- craft custom fly-fishing poles in Lewiston, CA, in Trinity County.  I decided to use that as an opportunity to finally travel over CA 3 from Yreka to at least CA 299 (the farthest I'd gotten was Fort Jones about 30 years ago).  Reasonably fast road, except for some hairpin turns south of Callahan.  Unfortunately, my old buddy had moved back to his childhood home in upstate NY to be near his family because of health reasons (sadly, he was a lifelong heavy smoker!), so the detour was for naught.  But now I've clinched CA 3 north of 299; the section south to CA 36 is still untraversed.

Yesterday I drove the Pikeville, KY to Charleston, WV section of US 119 for the first time.

[Kacie Jane]

A road trip a couple of weeks ago from Regina (which I flew into), north to Humboldt, west to Rosetown, then south to Swift Current.  (The bottom of the rectangle back to Regina wasn't new mileage for me.)  So the last previously-untraveled segment would be SK-4 from Rosetown down to Swift.  Previously entirely untraveled highways would be 5, 16, and 20 to/from Humboldt and a tiny section of 14 in Saskatoon.

Ironically, for new mileage in my home state, it would be from October when we drove to Regina.  Eastbound gave me the Sumas border crossing on SR 9 for the first time, while westbound gave me US 97 between SR 20 and US 2 (not all of which was new, but I forget exactly which bits were).

For entirely new highways in my home state though, I'd have to go back a few years, it hasn't changed since the last time I posted it.  (It's SR 153, but I can't recall how long ago.)

[Thing 342]

I-97 between I-695 and MD 32 about two weeks ago, from a business trip to Baltimore and Ft. Meade.

[OracleUsr]

I-79 in WV
WV 527 in Huntington, and its extension route in Ohio (yes, we crossed the Ohio)
Back in September

[wanderer2575]

Two roads in one nonstop day trip the day after Thanksgiving:

I-76 Pennsylvania Turnpike between Breezewood and New Cumberland (I-83).  I've driven the Turnpike between the Ohio line and Breezewood a zillion times, but this was my first time driving it east of Breezewood.

Then I-83 between the Turnpike and Baltimore.

I was desperate for a different route to Baltimore, even if it took me out of the way.

Says everyone who has endured US 15 through Shamokin Dam ...

You're certainly not kidding.  CSVT can't get done soon enough.

[DJDBVT]

Either NY 9D or the eastern leg of VT 279

[sbeaver44]

Last outright new road is probably PA 402 back in Nov.
