Yes, and it belongs in usanp. The Grant Grove segment route file is ca.kincanrd_gra.wpt, and should be in the Github master already even though it's not in the .csv files. I also have a local copy if needed.
Also, I suggest renaming that file to ca.kincanrd.wpt, after renaming the file already with that name to ca.kincanrd_ced.wpt The Grant Grove segment of Kings Canyon Rd. is used by all visitors to the park; the Cedar Grove segment is used only by those going out to the end of the highway, and is closed much of the year due to snow. In any case, the csvs should indicate that the KinCanRd segments are in different parts of the park.
One other option is a single KinCanRd file that includes the Grant Grove and Cedar Grove segments of Kings Canyon Rd., and the part of CA 180 connecting them.
I can go ahead and implement those changes, as well as a conforming relabel in the Generals Highway file (CA180 -> KinCanRd), when I have time while on the road.
