The Indiana Bridge Company digital collection contains records of the Indiana Bridge Company including drawings, photographs, and documents from 1886 to 1981. Headquartered in Muncie, Indiana, the Indiana Bridge Company built thousands of steel structures throughout the state and around the country. The earliest contracts were for bridges, trestles and bridge abutments, but the company soon expanded to other types of engineering structures and provided structural steel for buildings. The drawings in this collection are stock plans, engineering tables, patterns and standards for bridges and other steel structures. Also included are photographs of construction projects, facilities, and employees, as well as agreements between the company and the United Steelworkers of America Local Union No. 3124.
