Rising two stories, the gray steel framework of BNA Bank's downtown Tupelo location is in its early stages. When complete, the 18,000-square-foot building will be home to the New Albany-based bank as well as a couple of other tenants. Bank officials, joined by city of Tupelo and Lee County officials and others, had a ceremonial groundbreaking Tuesday at the site on West Main Street next to the railroad tracks. "We've done well in those years," CEO Bo Collins said. "Northeast Mississippi is our golden spot on earth. We feel like it's a diamond in the rough." With some $678 million in assets, BNA Bank has expanded into Lee and Lafayette Counties in recent years. Its first foray outside its home market was in Tupelo in the Belden area in 2007, followed by an opening on Tom Watson Drive in 2015.
