The End of the Steel Era in Infrastructure For nearly 100 years, steel rebar dominated infrastructure construction in the United States. From bridges and highways to marine structures and tunnels, steel shaped modern America. But time and science have revealed steel’s irreversible weakness: corrosion. Today, corrosion-related failures cost the U.S. economy over $22 billion annually, according to the Federal Highway Administration.Saltwater exposure, freeze-thaw cycles, chemicals in concrete, and environmental conditions steadily attack steel — weakening structures from within.
