New Mexico State Road 6 (NM 6) is an east - west state highway in the state of New Mexico. NM 6's western terminus is at Interstate 40 (I-40) west of Albuquerque, and the eastern terminus is at NM 47 in Los Lunas.
NM 6 begins at an intersection with Interstate 40 (I-40) about 30miles west of Albuquerque. The road travels to the southeast and then to the east. It has an interchange with I-25 in Los Lunas. The road passes through the village of Los Lunas as Main Street, crossing the Rio Grande before its eastern terminus at NM 47. Some maps show NM 6 continuing south concurrently with NM 47 through Belen and onward to U.S. Route 60 (US 60). This alignment is not reflected in the state highway log.
Much of NM 6 follows the historic alignment of US 66 and is signed as such.
