Does the report mention a fabricator or contractor, perchance?
This is not a deck plate girder bridge. It is a steel box bridge. According to a report by the The National Academies of Sciences, Engineering, and Medicine, here is the description.
The 2110-ft single-track Kansas City Southern Railroad bridge over the Arkansas River near Redland, Oklahoma is a continuous box-girder structure having nine spans. Approximately 2400 tons of ASTM A588 weathering steel, left unpainted, were used. The 24 individual box units, ranging in length from 42 feet to 117 feet and in weight from 44 tons, were shop-fabricated by welding. Web and flange erection strengthening and stiffening were found necessary. Pier and abutment stresses and stability were reviewed.
