Los Angeles artist and photographer Jason Paul Bennett embarked on a Route 66 trip from Chicago to L.A. last year, and shot more than 5,400 images to document it.
Bennett has a dedicated site, Passenger Side, to those photos. For a donation, yYou can download all 5,40o or so high-definition photos. You also can see about 170 of those photos in a slide show, or in these two YouTube videos below.
I found a number of the images to be quite striking.
