U.S. Route 80 (US 80) was a major transcontinental highway in the U.S. state of New Mexico from November 11, 1926, to October 12, 1991. Nationally, US 80 stretched from San Diego, California to Tybee Island, Georgia, going through southern New Mexico from El Paso, Texas, through the towns of Las Cruces, Deming and Lordsburg before entering Arizona. US 80 was a modest 191 miles (307 km) long (compared to US 80 in Arizona which was almost 500 miles (800 km) long) and was eventually replaced by Interstate 10 leading to the complete removal of US 80 in New Mexico. State Road 80 is a remnant of this route.
