support. The efforts of the new association paid off in November 1987, when the Arizona State Transportation Board designated several sections of old US 66 as Historic Route 66. The victory was marked by a ceremonial ribbon cutting for the new historic route in Seligman on April 23, 1988. This event was also the beginning of the first annual Route 66 Fun Run, an event where historic cars drive together down Historic Route 66 from Seligman to Kingman. The success of Historic Route 66 made Angel Delgadillo a popular figure among Route 66 enthusiasts around the world. Delgadillo has since been hailed as the "Guardian Angel of Route 66" and "Mayor of the Mother Road", among other nicknames. The ADOT Parkways, Historic and Scenic Roads program continues to recognize certain sections of former US 66 as Historic Route 66. The longest sections of the designated historic route follow the original US 66 between Topock and Seligman through Oatman and from Flagstaff to Winona. Other smaller sections of Historic Route 66 comprise former US 66 segments that are currently or were once designated as I-40 Business. This is the case in Ash Fork, Williams, Winslow and Holbrook. Flagstaff is the only city in Arizona where the Historic Route splits into two alignments, the first along the aforementioned route to Winona and the second taking a small section of later US 66 to a junction with I-40 immediately east of Flagstaff. The discontinuous sections of Historic Route 66 are all connected by I-40. As there are no designated sections between Holbrook and New Mexico, the Arizona historic route officially has its eastern terminus in Holbrook. Former US 66 also has the honor of being designated part of the Historic Route 66 National Scenic Byway. The designation means the old highway is protected and preserved as both a National Scenic Byway and All-American Road under the supervision of the Federal Highway Administration. There is also a museum dedicated to Historic Route 66 at the Powerhouse Visitor Center in Kingman. A further byway designation was granted to the original section of US 66 through Oatman, designated the Route 66 Historic Back Country Byway by the Bureau of Land Management as part of the BLM's Back Country Byways system. The overall length of all combined sections of Historic Route 66 is . Until the addition of Historic U.S. Route 80 in 2018, Historic Route 66
