You can find NM 469 on maps of the state. It's a highway that goes from Ute Lake on the Canadian River to Grady on the Caprock 35 miles north of Clovis. However, NM 552 is more mysterious. It appears on no map of New Mexico that I know of.
This intersection is on US 54 two miles southwest of Logan (22 miles northeast of Tucumcari).
