The Federal Highway Administration is turning to risk-based, data-driven ways of evaluating and rating bridges. Shay Burrows, team leader for structures safety and management for the FHWA, said that the agency is replacing traditional sufficiency rating numbers with simpler terms such as “good,” “fair,” and “poor” in describing bridges.
Speaking to attendees of the International Bridge Conference last month, he noted the recently issued “Refined Analysis in Bridge Design and Evaluation” manual from the FHWA, which provides guidelines for engineers to use “refined” analysis in modeling bridges.
