The construction of a new Coal Gasification Plant in Edwardsport, Indiana required transportation of super loads of heavy plant components that weighed between 306,000 and 1,117,000 pounds. These loads needed to cross 8 elevated bridges, 7 of which featured 2 to 5 spans with advanced deterioration. The remaining bridge consisted of a 16-span, 2,408-foot-long structure across the White River, a major river crossing.

Moving such heavy loads requires a state permit to assess safety and the bridges’ ability to withstand the weight. Lochmueller Group (Lochgroup) provided preliminary bridge load rating analysis and weight distribution of various load configurations. Bridges were inspected before, during, and immediately following completion of a super-load crossing. During the construction of the plant, Lochgroup engineers oversaw more than 70 moves, including the heaviest load ever to be permitted on Indiana highways.
