Topock. The section of US 66 through Arizona remained unaltered until 1979, when AASHTO approved a request from California and Arizona to truncate US 66 from Needles to a junction with I-40 and US 666 in Sanders. However, the Arizona Department of Transportation (ADOT) continued to recognize the US 66 designation west of Sanders, establishing a signed western terminus at I-40 in Kingman. Following the completion of the Williams bypass in 1984, ADOT approved a plan to deal with the remains of the highway in Arizona. All of US 66 in Arizona was no longer recognized as an active U.S. Highway. The sections of US 66 that were not concurrent with I-40 were re-designated as multiple Business Loops of I-40 and the section of highway from Kingman to Seligman was re-designated State Route 66. The section from Seligman to Crookton was abandoned to Yavapai County. On June 26, 1985, AASHTO approved a request by the states of Arizona, New Mexico, Texas, Oklahoma, Kansas and Missouri to retire the US 66 designation from the U.S. Highway System. Historic Route 66 A Seligman-based small business owner named Angel Delgadillo had observed the impact that the decline of US 66 and establishment of the I-40 bypass had on his town. Delgadillo, a Seligman native, had been operating his privately owned barbershop since 1950. When I-40 had been completed around Seligman, the number of cars traveling through Seligman substantially decreased from thousands per day to only a handful per day. This also meant a great decrease in Delgadillo's business. By 1986, Delgadillo had been attempting for years to get former US 66 in Arizona designated as a historic route with little to no success. The same year, the Atchison, Topeka and Santa Fe Railway ended employee layovers in Seligman, decreasing Delgadillo's business even further. On February 18, 1987, Delgadillo organized a meeting of 15 small business owners with establishments along old US 66. Among the attendees was Delagdillo's older brother, Juan Delgadillo, who owned Delgadillo's Snow Cap Drive-In just down the street from Angel's barber shop. The businessmen met at the Copper Cart Canyon restaurant in downtown Seligman and agreed to form the Historic Route 66 Association of Arizona. The new association began lobbying and meeting with state level politicians as well as multiple chambers of commerce for support. Delgadillo even began selling US 66 themed merchandise at his barber shop to gather further
