The main objective of this study was to review a Bridge Priority Ranking System for Bridge Replacement developed by the Kentucky Transportation Cabinet Division of Maintenance. The system ranked bridges for improvement (rehabilitation or replacement) based on a benefit/cost ratio.
The system was used to rank a large data base consisting of 267 bridges. Analysis of the rankings revealed that the ranking system gave priority to bridges having low improvement costs. Many of those had low traffic volumes and subsequently, they had high costs of improvement per vehicle served.
The equation used to compute bridge deficiency points was revised. Several proposed alternate ranking systems were analyzed. Those systems and their analyses are discussed.
