In 1971, the largest civil engineering feat of the US Army Corps of Engineers was completed, a project which turned one of the largest rivers in the United States into a commercially navigable waterway.

Join me today to learn about the McClellan-Kerr Arkansas River Navigation System and why it might be one of the most economically significant construction projects in Arkansas history.
