While not as historically significant as the "National Road" (US 40) or "Lincoln Highway" (US 30), U.S. 70 was one of the prominent east-west highways across America, and was known as Broadway of America. In the heart of Dickson, TN, this is all that remains of a mural that depicts the route of Broadway of America through Tennessee, however with East and West switched. Towns identified along the mural are Bristol, Kingsport, Rogersville, Rutledge, Knoxville, Kingston, Rockwood, Crossville, Sparta, McMinnville, Woodbury, Murfreesboro, Nashville, White Bluff, Burns, Dickson, Tenn City, McEwen, Waverly, Camden, Bruceton, Huntington, Jackson, Brownsville and Memphis. For those of you that are interested in such things, the route shows here follows what is now US 70S instead of US70 from Nashville to Sparta, which is an older configuration. Before it was part of Broadway of America, this route was originally known as the Memphis-to-Bristol Highway or State Route 1. I'd love to find more information about this, or see an old picture of it in it's glory days.
