Gateway sign along U.S. Route 66 as it begins its eastward wind through Tulsa, Oklahoma,. (There’s a similar one on the eastern side of town. Called “The Mother Road” by its aficionados, Route 66 was the original paved, mostly two-lane highway that ran from Chicago, Illinois, to Santa Monica, California during the “Golden Age of Driving” in the 20th Century. Only pieces remain in many locations, including Tulsa. The diner closed in 2019. Photo by Carol Highsmith, 2020.
