The photograph below is of a portion of the 1926 alignment of U.S. Route 66 just east of Ash Fork, Arizona. This alignment of the road is several miles north of the post-war alignment that was replaced by I-40.
The road is much narrower than later versions. It has two traffic lanes but the paved portion of the road would have just been wide enough for passenger cars of the era to pass each other. Encountering a truck would have required a drive to pull over to the side of the road to allow it to pass. Pavement is the typical reddish colored macadam of the era. There are no paved shoulders or curbs throughout this section.
