This fact sheet provides an overview of Indiana Department of Transportation's (DOT’s) Member-level Redundancy in Built-up Steel Members Transportation Pooled Fund (TPF) study. It is one of the winners of the inaugural 2024 TPF Excellence Awards. This study, selected from a competitive field of 11 applicants, advanced research that addressed the analysis, design, evaluation, and safety inspection of internal redundant built-up steel bridge members. As a result of extensive collaboration and research, the study team created two new American Association of State Highway and Transportation Officials (AASHTO) guide specifications. Transportation agencies around the country already use the guides to evaluate existing steel bridges and inform new designs.
