Old US 66 continued in a straight southeasterly direction for , then made a long curve south and east around a large volcanic bluff. After curving around the bluff, US 66 continued into Seligman, becoming Chino Street (today part of the Seligman I-40 Business Loop) into the center of town. Seligman is the birthplace of the first Historic Route 66 Association of Arizona, established by local barber Angel Delgadillo in 1987. The association obtained the first "Historic Route 66" designation, which the state initially placed on the segment of US 66 between Kingman and Seligman. East of Seligman, old US 66 diverged from the current business route. Where the business route turns south to return to I-40, US 66 headed southeast on Crookton Road. US 66 proceeded to follow Crookton Road through high desert towards Ash Fork.
