I'm sure this subject may have been mentioned within another thread (maybe?), if not a whole thread of its own, but oh well, here goes................
Got distracted the other day with GSV (that seems to be a developing habit), and came across this:
Without warning, no JCT, no city limit, no state-maintenance-ends, no county line, no END signs, no state line, not even a county road or other intersection of any kind -- none of those -- this happens
FM 1993 => FM 1001: http://goo.gl/maps/pcBE7
2 clicks down, then turn around....
FM 1001 => FM 1993: http://goo.gl/maps/moQro
Yes, the pavement appearance changes, which would make it look like a county or state line, but it's not. There is a CR turnoff nearby, but it is away from this transition point. I think there are probably 1 or 2 other similar spots elsewhere in TX, but not exactly like this. If the local district wanted 2 different FMs, to me it would have been more logical to wait on a transition until an intersection with another numbered road (most likely another FM).
Are there any examples elsewhere like this (no smooth transition, no warning)?
VA 33 changes into US 33 somewhere near the Siegel Center in Richmond, however the transition is not marked at all
FL 826 changes at a 90 degree curve NW of Miami along the Palmetto Expressway. It is signed N-S and E-W where it runs those directions, but no signage to inform you at the exact location.
NY 7 silently becomes a N-S to E-W route near Binghamton, NY.
I believe US 101 silently changes orientation in the Olympic Peninsula. At least on GSV I could not find where it goes N to E and E to S and the other way N to W and then W to S.

There are plenty of examples of changes in posted direction, with US 321 in Tennessee being the oddest example I know of.
The OP is inquiring about one route randomly changing numbers at some arbitrary spot.
Closest example I can think of was --
WAS -- KY 211 and KY 1722 north of the Licking River (not sure if it was in Bath, Rowan or Fleming county) but after driving through there last fall for the first time in about 30 years, I noticed that the road is now entirely KY 1722, and the switchover is at an intersection of a county road.
US-21 turns into SC Secondary S-7-406 at an arbitrary point on Hunting Island.

Florida we have many. https://www.google.com/maps/@29.143359,-80.987032,3a,75y,90t/data=!3m4!1e1!3m2!1sFNUtnvimd2-whGvUtYcLCw!2e0 Here SB FL A1A becomes WB FL 421 at US 1 without warning as you can see in the photo that only a NB and SB US 1 assembly is present with no END sign nor another straight through shield for FL 421 either.

Sorry I do not know why I thought direction. Anyway, US 211 becomes VA 211 at New Market.

Oh yes, FL A1A does it along the Beachline Expressway in Cocoa, FL where it ends at US 1 without a warning sign anymore. https://www.google.com/maps/place/Cocoa,+FL/@28.401172,-80.747426,3a,75y,270h,90t/data=!3m4!1e1!3m2!1s_EvofC7sdhR58P3Rc7an5g!2e0!4m2!3m1!1s0x88e0ab9dbaf097fb:0x27f09eeda673701e There used to be a TO FL A1A NORTH assembly at the point of diverge for US 1 exit that directed motorists off the freeway, but no more.

It looks arbitrary because it is posted in the wrong location. US 21 ends at the entrance to the State Park, which was moved from where the END sign is currently. US 21 used to go over to the beach...
Note that the current online Beaufort County map shows US 21 ending 2.4 miles from Fripp Inlet (http://206.74.144.9/gismapping//pdfs/County/Beaufort_County.pdf) which corresponds to the current state park entrance.

Usually, A1A doesn't have post "END" signs, because there's many segments. Never saw one at the northern terminus at US 301/23/1, nor the last section at Key West. Sometimes you see a trailblazer that it becomes another road, most times there's not much notice.
You don't see much of this behavior in Florida, although some of the more rural county roads do this from time to time. CR709 and CR609 used to do this at the St. Lucie/Martin county line, but there's no evidence of the change anymore. Probably has to do more with a nonchalant attitude towards replacement signage than anything else.
QuoteSorry I do not know why I thought direction. Anyway, US 211 becomes VA 211 at New Market.
Yeah, but that one's signed. The OP is looking for examples that AREN'T signed...
Virginia does have some posted primary routes I believe meet the OP intent:
VA 142
VA 149
VA 154
VA 179
VA 184
VA 187
VA 203
VA 213
There may be others...

Does VA 68 become a secondary at the county line? I don't remember it being signed the one time I was there, but if it's at the county line, that's not an arbitrary spot.
VA 78's conversion to secondary is signed.

Yes...VA 68 ends at the Lee County line. Route change signed in both directions when I visited in 2008.

VA 69 does apply, it is not posted at its west end in Austinville.
Once upon a time, to drive from the eastern suburbs of Pittsburgh to Pittsburgh International Airport, you had to use I-376, I-279, U.S. 22/U.S. 30 and PA 60, all on one alignment. More ridiculously, the exit numbers decreased from the teens to 1 on I-376, and from 6 to 1 on I-279, with two or three unnumbered exits on U.S. 22/U.S. 30, and increasing exit numbers from 1 to 6 on PA 60.
Thankfully, that was changed in 2009, when the entire highway was designated I-376, and the exit numbers decreased from the 80's to 53.
