US 60/US 84 passes through Tolar near the De Baca–Roosevelt county line. The two routes do not stay in Roosevelt County for long, however, proceeding into Curry County west of Melrose. The highways pass through Melrose, St. Vrain, and Grier before widening out to a four-lane highway as they approach Clovis, the Curry County seat. In Clovis, the home of Cannon Air Force Base, the highways meet up with US 70, which joins the concurrency. The three highways proceed through Texico, and just before the Texas state line, US 60 leaves the concurrency and heads northeast while US 70/US 84 continues eastward. For the distance of more than 300 miles (480 km) between Abo Pass and Amarillo, the highway parallels the Southern Transcon, one of the busiest transcontinental railroads in the west.
