I have used these grid maps for Kimble, Sutton, Edwards, Kerr, Gillespie, Mason and Menard counties. They only show Interstate, US, SH, FM, RR, RM, LP and county roads. I have seen a few named roads, which I assume to be county or state maintained like Old Segovia Rd in Kimble County. My guess is TxDOT does not recognize Bofecillos Rd as any of those road designation types I mention above. Admittedly that doesn't make sense considering it is a state park. I only use them as one source to help keep me off ghost county roads that show up on some mapping apps. They are lacking in some ways for sure.
