When originally commissioned on 11 November 1926, U.S. Route 70 ran between Beaufort, North Carolina and U.S. Route 66 in Holbrook, Arizona. This older route ran from present day US 70 in Clovis, New Mexico through Vaughn, Willard (where former child route U.S. Route 470 branched off to Albuquerque) and Springerville, Arizona before finally reaching US 66 in Holbrook. In 1932, US 70 was rerouted to El Paso, Texas from Clovis along what is today U.S. Route 54. The re-routing temporarily removed US 70 entirely from Arizona. The old route to Holbrook was replaced by U.S. Route 60 and U.S. Route 260. That same year, the eastern terminus of US 70 was extended to Atlantic, North Carolina, where it remains to this day (albeit in a slightly different location). In 1934, the routing was changed yet again and US 70 was rerouted to California through Las Cruces, New Mexico, Deming, Globe, Arizona and Phoenix to a junction with U.S. Route 99 around Mecca. Between Globe and its new western end in California, US 70 was paired with US 60. A year later, US 70 was extended along Valley Boulevard and reached downtown Los Angeles at U.S. Route 101 running concurrent with US 99 and/or US 60 throughout its course west of Globe. Beginning in 1964 it was decommissioned in favor of Interstate 10 or US 60. After being removed from California, US 70 ended at the California/Arizona state line in Ehrenberg until 1969, when it was further truncated to its current endpoint in Globe. US 70, unlike many other decommissioned US Highways in California, doesn't have a state route that was numbered after it and taking over its path (unlike US 60, which had State Route 60 to replace it), since the current State Route 70 bears no relation to this highway.
