Exit 47, the new exit, merges onto Highway 61 South (also known as Burkesville Street/Road) and drivers can choose to go north and visit the new Holladay Place Shopping Center, home of Columbia's Super Wal-Mart or go to Burkesville to the south. The Louie B. Nunn Cumberland Parkway runs through Columbia as it extends from Bowling Green, KY to Somerset, KY. This Parkway is a future Corridor of Interstate 66. The addition of an interchange with a 2006 reconstruction of Highway 61 South, Columbia now has two exits on the Parkway.
