 But it was never a fully formed road, and its route has shifted many times over the years. And so the Lincoln Highway, as the U.S. Army said as it tried to cross it in 1919, really exists more in the imagination than it does on paper. I'm sure glad that you brought up that 1919 episode, because I didn't really know what the Lincoln Highway was, but I have a vague memory of hearing this story when I was a kid in school about Dwight Eisenhower in 1919. What did he do?
