U.S. Route 70 (US 70) is a part of theU.S. Highway System that travels fromGlobe, Arizona, east toAtlantic, North Carolina. In the U.S. state ofNew Mexico, US 70 extends from the Arizona state line south ofVirden and ends at the Texas state line inTexico.
After entering the state ofNew Mexico, US 70 heads southeast signed as the Duncan Highway. Five miles (8.0 km)[2] after crossing the state line, it serves as the southern terminus forNew Mexico State Road 92 (NM-92). US 70 does not have another highway junction for 21 miles (34 km),[2] where it meetsNew Mexico State Road 464 (NM-464) andNew Mexico State Road 90 (NM-90) three miles (4.8 km)[2] north ofLordsburg. At Lordsburg, US 70 joinsBusiness Loop 10 and Motel Drive heading east, and joinsInterstate 10 eastbound just outside the city. US 70 and I-10 will run concurrently for the next 114 miles (183 km) before splitting off inLas Cruces at exit 135. Signed as Picacho Avenue, US 70 passes through the unincorporated community ofFairacres and crosses theRio Grande before meeting Main Street, where it follows it northbound. US 70 then junctionsInterstate 25, signed as the Bataan Memorial Highway, and continues as acontrolled-access highway until the town of Organ, before entering the foothills of theOrgan Mountains.

As a divided highway, US 70 crosses theOrgan Mountains via the San Augustin Pass and descends to the valley floor of theTularosa Basin, crossing theWhite Sands Missile Range. Overhead missile tests can close the highway for a few hours; this generally happens once or twice a week, and typically only for an hour at a time.[3][4] Shortly after the interchange withNew Mexico State Highway 213 (NM-213), the speed limit raises to 75 miles per hour (121 km/h) and will continue until a border control checkpoint 1 mile (1.6 km) south of the entrance toWhite Sands National Park. The road then passes the entrance to White Sands National Park, and shortly after that passes the southern end ofHolloman Air Force Base. It then turns northbound, and picks up a concurrency withUS 54 upon enteringAlamogordo, and continues north on the Charlie Lee Memorial Relief Route, a bypass west of the city. On the north end of Alamogordo, US 54/US 70 intersects the western terminus ofUS 82 nearLa Luz, and US 54/US 70 continues north. The concurrency with US 54 lasts untilTularosa, and the highway remains divided until US 70 and US 54 diverge. Continuing northeast, US 70 begins the ascent into theSacramento Mountains and enters theLincoln National Forest. The road then runs across theMescalero Apache Indian Reservation and into the resort towns ofRuidoso and neighboringRuidoso Downs. InHondo,US 380 joins for a concurrency. US 70/US 380 then entersRoswell, signed as 2nd Street, with a bypass heading northeast with the US 70/US 285 Truck Route as part of the Roswell Relief Route. US 70 then meetsUS 285 at Main Street, and joins it northbound for a short concurrency. US 70 then heads northeast at the northern interchange with the Relief Route, continuing as a divided highway. Signed as 2nd Street, US 70 entersPortales, and splits into two one way roads in downtown before rejoining at Boston Avenue. US 70 then turns northeast towardsClovis. Signed as Prince Street, US 70 enters Clovis from the south. Once downtown, US 70 joinsUS 60/US 84 heading east, and will run concurrently with all three highways untilTexico, where US 60 leaves just before the state line, and US 70/US 84 enterTexas.
When commissioned in 1926, ran from present day US 70 inClovis, New Mexico throughVaughn,Willard all the way toHolbrook, Arizona. In 1932, US 70 was rerouted toEl Paso, Texas, and the old routing was transferred to US 60 and US 260.[5] In 1934, the routing of US 70 was changed again, toLas Cruces; the old route was transferred to US 54.[6]
On July 12, 2021, US 70 between NASA Road and the entrance of White Sands Missile Range was closed to traffic. The night before, heavy rain from thunderstorms caused about 4 feet (1.2 m) of mud to close the 7-mile (11 km) section. The highway was reopened the next day.[7]
