Interstate). The earlier route of former US 66 (used through 1940), and current route of US 89, continue northeast from this intersection towards the Flagstaff suburb of Townsend. Flagstaff to Winslow On the outskirts of the Flagstaff metropolitan area in Townsend, US 66 split from US 89. US 89 heads north towards the Glen Canyon Dam and Page, while old US 66 took an abandoned gradual curve to the east onto Townsend–Winona Road. The highway proceeded to wind through small pine forest wilderness, passing several small communities along the way, heading first east, then southeast near Sunset Crater and several other extinct volcanic cinder cones of the San Francisco Volcanic Field. Shortly before reaching the current route of I-40 east of Flagstaff, US 66 passed through a small unincorporated community called Winona, made famous in the song "(Get Your Kicks on) Route 66". In Winona, US 66 crossed an abandoned steel bridge. Today, the modern road uses a concrete bridge built right next to the older structure. US 66 proceeded to cross over the Santa Fe Railway on an overpass heading out of Winona. Where Townsend–Winona Road continues south to end at I-40 exit 211, US 66 continued east along the southern side of the railroad on Coconino County Route 394. Approximately southeast of exit 211, the county route dead-ends at the westbound lanes of I-40. US 66 continued on an abandoned highway grade southeast of this point (some of which has been overlaid by I-40), then zig-zagged northward, crossing a concrete bridge over a small gulch. North of the gulch, US 66 turned southeast, passing north of the abandoned Twin Arrows travel center. The old highway continued on an abandoned roadway and part of the south frontage road, before gradually being subsumed into the route of present-day I-40. This is also the area where US 66 left the pine forest area which started near Ash Fork and re-entered high desert terrain. Near Exit 225, US 66 diverted from I-40 southeast on Buffalo Range Road. Around southeast of the Interstate, US 66 curved east on an abandoned highway grade to rejoin the route of I-40, where Buffalo Range Road turns sharply to the southwest. US 66 proceeded to follow I-40 east for , then split off again to head straight southeast, followed by a sharp curve to the north to cross the Canyon Diablo Bridge over Canyon Diablo into Two
