The industrial and agricultural heart of Michigan's Thumb region is captured here during the mid-1950s, showing the major urban centers of Flint, Saginaw, and Bay City before the full expansion of the modern interstate system. These cities, clustered near the base of Saginaw Bay, were supported by a dense network of railroads including the Grand Trunk and Chesapeake and Ohio lines. The map illustrates the era's reliance on both the river systems, such as the Flint River and Cass River, and the heavy maritime traffic of Lake Huron.
