A sign saying "Cemetery Road" – maybe you'd want to steal that. But who wants a sign that reads "Route 320"?
Today's Route 320 was a originally a pair of locally maintained roads. In 1960, the state Committee to Reclassify All Public Roads recommended adding them to the state highway system. In 1962, they were given the unsigned designation SR 520; a year later, SR 520 became Route 320.
