Columbia's Main Street, which was in the original town plan, was present Jamestown and Greensburg Streets. The name of Main and Market, which was also an original street, now Burkesville and Campbellsville Streets, were renamed about a quarter century later, upon use of different "important" routes to nearby towns.

Main was so named, heading toward Greensburg, because Greensburg was the seat of Green, the parent county of Adair, and the original settlers of the village that came to be Columbia had to travel to Greensburg for any legal business and for additional trading.

There is much old history in this town and county. - MW
