Rare BOA mural discovered.
The Broadway of America was an important highway. Formed in the fall of 1927, it was the “last” named highway, and learned from the mistakes of its predecessors. As an organization, it continued (regionally) until the late 1970s.
The BOA started in New York City and ended in San Diego. It didn’t follow US 70 all the way. Making the cross-country trip, the BOA stitched together eleven different US highways that had already been improved; this is how it succeeded where other named highways failed.
Tennessee is the only place along the BOA that still retains the name. And this find contributes to our understanding of the highway.
