Georgia Tourism is currently rewriting the Black Heritage Trail tourism brochure product in February 2019. It is a cultural trail of 20-30 visitable sites that lie near or on the Dragonfly Trail Network of Columbus. The NRT symbol is affixed to the 14th Street pedestrian bridge that brings one across the Chattahoochee River from Alabama to Georgia where one can begin visiting the black heritage sites such as Springer Opera House, Black Art in America gallery, Primus King Site, Prince Hall Masonic Lodge where MLK Jr. spoke, Ma Rainey Museum, and many more. Tours are intended to be offered via biking, walking, and tour vehicle. Loads of lunch stops along the way include black-owned businesses like the Royal Cafe, Chesters BBQ, and Skipper's seafood. Check with the Columbus CVB for final brochures/website in later 2019.
