Granite City's history: from 1890s steel to Route 66
Granite City was founded in 1896 by William and Frederick Niedringhaus, two brothers from St. Louis who established a steel and graniteware (enameled cookware) manufacturing operation on what was then undeveloped Madison County farmland just east of the Mississippi River. The brothers chose the location for its proximity to the river (for shipping access), the railroads, and the available agricultural land for industrial expansion. They platted the original town site to support their workers and named it Granite City after the graniteware product line that was the original manufacturing focus.
By the early 1900s the steel-and-graniteware operation had grown into one of the larger industrial complexes in southern Illinois. The Granite City Steel Works expanded substantially through the 1900s-1920s, and supporting industries (rolled metal products, manufactured equipment, related supply chains) developed in the surrounding area. By 1920 Granite City had grown to roughly 14,000 residents — most of whom were direct or indirect employees of the steel operations.
The Route 66 era (1926-1980s) overlapped substantially with the steel-industry peak. Route 66's original 1926 alignment passed through Granite City along what is now Madison Avenue and 20th Street, and the 1936 realignment to the Chain of Rocks Bridge cemented Granite City's role as the last Illinois Route 66 city before the Mississippi crossing. The combination of steel-industry employment and Route 66 traveler traffic produced a robust mid-century Granite City economy with substantial downtown commercial development, multiple movie theaters, churches, schools, and the worker-housing neighborhoods that still define the city's character today.
