U.S. Route 84 (US 84) is a part of the U.S. Highway System that travels from Pagosa Springs, CO to Midway, GA.

US 84 enters New Mexico at Rio Arriba County 28 miles (45 km) south of its terminus at US 160.

15 miles (24 km) further south, the two return to surface street status and then travel past downtown Santa Fe via St. Francis Drive.

All four highways head east and slightly to the south to avoid the Sangre de Cristo Mountains.

Here, about 280 feet (85 m) before the Texas–New Mexico state line, US 60 splits from US 70/US 84 with US 70/US 84 continuing east into Farwell, Texas.

[2] Despite being a west-east route, US-84 is signed as north-south between Fort Sumner and the Colorado border.
