I'll even accept that google gave it a number when <Minor Highway> signs only give us the name.
You mean like the highway near here which Grgle Maps calls "NJ State Highway 444", which everyone else in the known universe calls "the Garden State Parkway"?
Heck, now I'm wondering how come they don't call the Belt Parkway "NY State Highway 907c".
(For the benefit of the non-roadgeeks here, if any, these are "reference route" numbers, not actual signed highway numbers. See here

That "road" has been overgrown and pothole ridden for a couple of decades and is completely undrivable (you can't even turn onto it from one end anymore). It's a private road, not maintained by the county and the people who live on it a) don't care, and b) don't like other people using their road as a short cut out of the neighborhood which is probably why they let it go to rot.
Sounds like Clark Rd north out of Eldred NY. The maps all show it's there; even the current print maps have it. But there's no road anymore, just a sort of longitudinal clearing through the trees. You can take a look at it on the satellite view, and if not for the line on the map you would never know there had ever been a road there.
Many years back, say about 1988, before GPSen or Google Maps existed, my parents tried to drive this non-road up to visit my sister in summer camp, this being the most direct route I could find. (I was the one with the map collection, so I navigated.) The road gets narrower and narrower, eventually we find a sign "Road Closed". So what, the Connecticut Turnpike always had "Road Closed - Proceed At Your Own Risk" signs up during construction, so we figured it was just the local road department CYAing. Keep proceeding north. Pavement goes. Then the dirt road goes too. Nothing but two ruts with a huge hump in between, overgrown with grass. My dad was driving with one wheel on the hump and the other in the forest, and you could have gotten under the car and changed the oil. I was actually walking in front of them with a long stick to poke into the various ponds that covered the right-of-way from time to time, disturbing frogs etc. just in case the thing was deep enough to swallow the car. Finally we get to the end of the abandoned stretch, and whaddaya know, there's an old wooden bridge...
Thank G_d it was still strong enough to hold the car.
We get to the camp, and I tell one of the staff there how we'd come. He looks at my mother's car, a 1986 Chevy Celebrity with about three inches ground clearance, and he says "You took that
over the Blind Pond Turnpike? You're nuts."
A few weeks later, we had the car in for service, and the mechanic wants to know how come the bottom of the chassis is full of grass. My mother told him "We got lost in the woods." About six years later, when I'd finally gotten a 4x4 with higher clearance and shield plates, I went back up there and drove the road again, this time at about five times the speed: 15mph rather than 3....
