Roadways Named in Honor of Rev. Martin Luther King Jr.

Back in 2018, National Geographic ran a story on Where the Streets Have MLK's Name, which attempted to identify the locations of roadways named in honor of Rev. Martin Luther King Jr. The article wasn't clear on its methodology, noting that "No comprehensive global index of the streets named for King exists, but there are more than a thousand entries for such eponymous streets in OpenStreetMap." So, while certainly less-than-perfect, here's a SAS ODS Graphics attempt at a Continental U.S. map of the JSON latitude/longitude results of an Overpass query of OpenStreetMaps nodes, ways, and relations containing "Martin Luther King" in the address field. Btw, Wikipedia also has a list of streets named after Martin Luther King Jr.
