Since I happened across one of these today, this seems like a trivia category I haven't seen yet.
The road: Sandy Valley Road in southern Nevada (accessible from NV 161 beginning near Goodsprings off I-15). It crosses the California line and continues paved as Kingston Road, but with no paved intersections, for only about 3 miles before the pavement ends. There's no pavement that connects to any other part of the California road network.
Any other roads are like this? State lines only, so you can't count Alaska, Point Roberts, or Minnesota's Northwest Angle.
ETA: Another one I thought of later today would be Harpers Corner Road in the Dinosaur National Monument, as it crosses from CO into UT and back into CO with no other connections after that point.
I don't know if this counts but there are dead end roads off of MN 23 in Wisconsin where the only access to this area is by going through Minnesota.

Va. Secondary Route 601 (Raven Rock Road [also seen references to it as Raven Rocks Road]) runs north off of Va. 7 (Harry Byrd Highway) in Loudoun County at Snickers Gap, across a tip of Jefferson County, West Virginia (where it is briefly county route 35), back into Virginia (but hugging the state line pretty closely) and then dead-ends in Virginia. Several homes in Jefferson County, W.Va. and a few dead-end streets can only be reached from the public highway network of Virginia.

Not sure if that is what you had in mind or not.
Alta Ski Road in Alta, WY comes to mind.
There is a dead end that crosses the MA/NH border between I-93 and MA/NH 28.

Can't tell for sure (no Street View there), but the north end of 601 would definitely count, and Kimble Road might seem to count for a crossing into WV. Nice!
There are a couple examples along the Virginia Beach, VA/Currituck County, NC line.
CA 299 is paved all the way to the Nevada state line. I wouldn't say that it doesn't go anywhere since the Nevada side used to be NV 8A but really the only place of substance is a ghost town called Vya. I'm fairly certain the road is still good even for a car all the way to NV 140.
There's a handful between New York and Vermont. In almost every case, the pavement ends somewhere on the Vermont side and the road continues as dirt/gravel, but there are a couple of dead ends as well.
None of the paved crossings dead end into Vermont. I checked this when I was counting how many paved crossings there for that earlier thread.
I believe the Pond Eddy Bridge crossing the Delaware River from NY 97 to dead-end roads on the PA side qualifies...

The continuation of Providence/New London Turnpike (CT 184 to its junction with CT 216) dead ends just across the RI line. It originally connected to RI 3, but was bypassed by I-95.

It looks like VDOT maintains the WV part of CR 35 per ftp://gis.transportation.wv.gov/2014CountyMaps/Jefferson_2_of_2.pdf

Or for that matter, anywhere outside the USA, as there are many subnational lines, but none are state lines. This disqualifies a part of Catalonia, Spain that is only connected by paved roads to Aragon, as neither are states.
There are some dead end roads that cross the Tennessee/Alabama state line (sometimes multiple times).

"State" or its equilvant in Portugese or Spanish is the name of the first level political subdivision in Australia, Mexico, Venezuela, Palalu, and Brazil. In at least the first two it has a similar meaning as in the US in a federal political system of twin soverignty and checks and ballances.
Germany's first level political subdivisions, which are "Land" or in plural "Lander" in German are generally translated as "states" rather than "lands" in English.

Last time I was there (quite a few years ago), I did find a West Virginia-spec sign at the state line, where County Route 35 begins (and then immediately ends).
Makes sense that VDOT would maintain this almost crazy-short section of West Virginia road. Imagine the time and fuel that would be wasted if a WVDOH truck had to make the long trip from someplace on the other side of the Shenandoah River, down Va. 7 and then north on 601 just to reach this.
I-684 enters Connecticut, but has no interchanges in that state. Ditto I-95 and DC.
Outside of the USA, there are a small handful of local roads in Lithuania that cross into and transit Russia for very short distances. They have ample signage warning of no pedestrians nor any other non-motorized traffic allowed and no stopping.
There is also a secondary local highway in Slovenia that transits about 2 km of Italy. It was fenced and so forth before Slovenia became part of the Schengen zone.

There are two streets in far Northwest DC not far from Sibley Hospital that cross into Maryland, join into a single street, and then dead-end, but I'm not sure they count because they're not open to the public. They serve the Dalecarlia Reservoir.
Regarding the routes cpzilliacus mentions between Virginia and West Virginia, I vaguely remember a newspaper article once talking about how those roads were problematic for residents because they had trouble getting emergency services and the like–ambulance drivers, for example, would hit the state line sign and would not continue further.
Would US-160 in far northwestern New Mexico count for purposes of this thread? It crosses in from Arizona and exits into Colorado a short distance later and the only turnoff is the short road to the Four Corners monument (and that road carries a fee to get to the monument). It's not a dead end. I wouldn't count the road to the monument because, while you could drive across the state lines on at least two sides of the monument, it's really just the parking area that lets you do that.
There are a few between New York and Massachusetts north of the Pike. All have no road connection to the rest of Massachusetts. Makes me wonder who does the plowing when the snow falls.
Here's an interesting possible example (https://www.google.com/maps/@34.9936286,-89.8884345,660m/data=!3m1!1e3) on the MS/TN border: a subdivision road that straddles the state line and has two roads that branch off of it, both of which dead-end before reaching another road in the same state.
You could probably find something on one of the oxbows of the Mississippi River. I assume the road to Kaskaskia doesn't count. :)
Probably one of several instances along Kentucky's land border, but I've been here.

The map is incorrect. KY 2060 is not a state road. It's been turned over to Pike County. This route is a Virginia secondary that briefly crosses into Kentucky, back into Virginia, then back into Kentucky.
