State Road 485 (NM 485) is a 3.9-mile-long (6.3 km) state highway in the US state of New Mexico. NM 485's southern terminus is near the small town of Jemez Pueblo, at NM 4. The route passes through land belonging to the pueblo near the Nacimiento Mountains and follows the canyon of the Rio Guadalupe until the pavement ends. The highway intersects and adjoins the Jemez Mountain Trail National Scenic Byway.
The road through the Rio Guadalupe box canyon bears the designation Forest Road 376 in Santa Fe National Forest near the unincorporated town of Cañones (or Gilman). The continuation as Forest Road 376 eventually terminates at New Mexico State Road 126 east of San Pedro Parks Wilderness. The route incorporates the Gilman Tunnels (1 mi (1.6 km) beyond the transition to Forest Road 376) which was part of the former Santa Fe Northwestern Railway (SFNW) through the canyon which was used to haul lumber from the Jemez Mountains. The railway opened in 1924 but never recovered financially from the Wall Street Crash of 1929, and ceased operations in May 1941 following flood damage from the Rio Guadalupe.
The entire route is in Sandoval County.
