By 1934, despite budget cuts to US 66, the construction work between Seligman and Crookton had extended to the previously paved section of US 66 northwest of Crookton. Construction work was also underway on US 66 between Ash Fork and Williams, part of the route from Williams to Flagstaff and the unpaved section of highway between Kingman and Peach Springs through Hackberry. Most of the highway between Holbrook and Lupton through Sanders and Navajo was also undergoing construction. road surfacing work was complete on US 66 between Williams and Bellemont, on a small section going through Peach Springs, between Oatman and Kingman and a small piece heading a few miles northeast of Holbrook. At this point, most of US 66 through Arizona was paved or undergoing resurfacing. The first known use of natural landscaping by the Arizona State Highway Department was performed along US 66 the same year.
