The railroad bridge over the Black River had a swinging section in order to let the tall steamboats pass through, as did most railroad bridges of this era.  The St. Louis, Iron Mountain, and Southern Railway Company built a branch line at the little town of Diaz that led from the main line between St. Louis and Newport northwesterly to Batesville and on to Springfield, Missouri.
