According to Max Rockatansky on AAroads in December 2016, Route J1 is deceptive. This route looks pretty good from Fresno County west from I-5 for a couple miles and east from Route 25 in San Benito County but really isn't. This is the second longest signed county route in California at 70 miles only behind County Sign Route J16. County Sign Route J1 basically is falling apart and is in terrible shape, you're in for a hell of a drive if you come this way. County Sign Route J1 gets pretty nasty eastwards after the first one-lane bridge about a half dozen miles from Route 25. Panoche Pass Summit is only 2,250 feet above sea level but the road is in terrible shape getting there. The advertised limit is 55 MPH but 35-45 MPH is really all you ought to be going for in the straights. The pavement is bad enough shape that 20-25 MPH is often necessary in sharp turns. If you're a one-lane bridge fan this is your road.

He also noted: J1 is closely signed to the original proposed alignment of Route 180 west of Mendotta to Route 25. Back in 1938 several maps show Route 180 actually on an alignment to Route 25 via Panoche Road. It would seem that many routes like US 101 in San Francisco, CA 33 in Fresno County, and even parts of Route 49 were actually signed on County/City maintained roadways.
