Arizona State Route 78 (SR 78) and New Mexico State Road 78 (NM 78) are a pair of adjoining state highways located in eastern Arizona and western New Mexico linking U.S. Route 191 (US 191) and Arizona State Route 75 near Greenlee County Airport to US 180 northwest of Cliff, New Mexico. It is also known in its Arizona stretch as Mule Creek Road and the A.M. "Curley" Traynor Memorial Highway.

Route description

NM 78 at mile marker 7

The western terminus of Arizona State Route 78 (SR 78) is located at a junction with U.S. Route 191 (US 191) and SR 75 at Three Way, Arizona near Greenlee County Airport. The highway heads northeast from this intersection along Mule Creek Road. There are a few hairpin turns along this stretch of highway as it follows the surrounding terrain, before crossing the Arizona–New Mexico state line.[1][3] Now called New Mexico State Road 78 (NM 78), the highway heads eastward through desert, passing through the community of Mule Creek, New Mexico. The road continues eastward until terminating at US 180 northwest of Cliff, New Mexico.[4]

History

State Road 78 (NM 78) in New Mexico was designated along its current route between the Arizona state line and NM 11 (now US 180) in the late 1920s.[5] It was extended to U.S. Route 60 via Mogollon by the mid-1940s.[6] The route between US 666 (now US 191) in present-day Three Way, Arizona and NM 78 at the New Mexico state line was originally an undesignated gravel road.[7] This section was not designated as State Route 78 (SR 78) until February 17, 1959.[8] SR 78 would remain a gravel road until 1961, by which point NM 78 had already been paved.[9] By 1971, nearly the entire highway had been paved with the exception of a portion near the New Mexico border.[10] In 1974, SR 78 was designated the A.M. "Curley" Traynor Memorial Highway.[11] During the 1988 New Mexico state road renumbering, NM 78 was truncated from US 60 back to its original eastern terminus at US 180 east of Mule Creek. The former eastern segment of NM 78, where the highway wasn't concurrent with US 180, is now designated as NM 159, NM 163 and part of NM 52.[6]
