which early pioneer took advantage of the national network of industrial systems to construct a bridge across the mississippi river?

The early pioneer who took advantage of the national network of industrial systems to construct a bridge across the Mississippi River was James Buchanan Eads. He designed and built the Eads Bridge, which spans the Mississippi River at St. Louis, Missouri, connecting to East St. Louis, Illinois. This bridge was constructed from 1867 to 1874 and was a groundbreaking engineering feat utilizing steel and pioneering caisson technology for its deep underwater foundations. Eads Bridge was the first bridge across the Mississippi south of the Missouri River and symbolized the integration of railroad and vehicle transportation at a time when railroads were expanding nationally after the Civil War.
