Known as a site on the Lewis and Clark National Historic Trail, the North Dakota capital sits across the Missouri River from Mandan. It landed in the top 50 in two categories: Prosperity (#41) and Product (#45). Bismarck landed #23 for Household Income (median $63,608) with the state government being its largest employer, followed by the healthcare industry, public schools, and the federal government. A major agricultural distribution center the city also made our top 10 for Convention Center Size, at #9. The Bismarck Event Center features a 10,000-seat arena, recently expanded 100,000 square foot exhibit hall, and the Belle Mehus Auditorium, a historic structure dating back to 1914. As the Bismarck Mandan Chamber EDC sets three key industries as targets for future business attraction—value-added energy, value-added agriculture, and equipment manufacturing—the city has more than $15-million in road upgrades planned for 2020 alone, while two new modern apartment complexes are to be complete by 2021 at a cost of $10-million and $7.7-million each.
