State Road 531 (NM 531) is a state highway in Rio Arriba County, New Mexico, United States, that connects New Mexico State Road 572 (NM 572) and County Road 340 (CR 340) in La Puente with New Mexico State Road 162 (NM 162) in Tierra Amarilla.
NM 531 begins at a T intersection with NM 572 and CR 340 in the unincorporated community of La Puente. (CR 340 heads northwesterly to Los Ojos and northbound NM 572 officially heads west to promptly ford the Rio Chama and on through Plaza Blanca to end at New Mexico State Road 95 [NM 95]. However, after NM 95 was extended west from Rutheron in 1969, the state has not maintained the river crossing [nor the adjacent sections of dirt road] along NM 572. Therefore, the ford of the Rio Chama is likely impassable.)
From its western terminus NM 153 heads easterly as a two-lane asphalt paved road to pass through the La Puente Historic District and leaves La Puente. Just over along its route, NM 153 crosses New Mexico State Road 112 (NM 112) at an intersection on the westernmost edge of the census-designated place of Terria Amarilla, immediately west of the Tierra Amarilla Elementary School. (NM 112 heads north toward Los Ojos and south toward El Vado.)
East of its NM 112 junction, NM 153 enters Tierra Amarilla and, just after passing the Escalante High School, enters the Tierra Amarilla Historic District. NM 531 then crosses U.S. Route 64 / US 84 (US 64 / US 84) later. (Eastbound US 64 / US 84 heads south toward Tres Piedras, Española, Taos, and Santa Fe. Westbound US 64 / US 84 heads north toward Chama.) farther east NM 153 reaches its eastern terminus at a T intersection with NM 162 in downtown Tierra Amarilla, and still within the Tierra Amarilla Historic District. (NM 162, which forms an eastern loop off of US 84, heads north toward 64 / US 84 and south toward 64 and then US 84.)
Mile markers increase from east to west.
