Kentucky Transportation Center Research Report
Kentucky’s 14,000+ bridges are key nodes within the state’s surface transportation network. They facilitate the movement of freight, commercial vehicles, and personal vehicles alike. Historically, the Kentucky Transportation Cabinet (KYTC) has prioritized bridge maintenance projects using sufficiency ratings. These ratings are based on three factors — structural adequacy and safety, design obsolescence, and an asset’s importance within the roadway network. Although useful, sufficiency ratings do not account for factors that should be considered during the prioritization process (e.g., condition factors, risk). To address the shortcomings associated with using sufficiency ratings, KYTC — with the assistance of the Kentucky Transportation Center …

Kentucky Transportation Center Research Report
Adopting a comprehensive suite of methods to track, analyze, and maintain data on bridge construction costs can help state transportation agencies identify and implement strategies to mitigate the influence of factors which escalate project costs. This report discusses how the Kentucky Transportation Cabinet (KYTC) should approach updating, maintaining, and analyzing its bridge construction cost data. Based on a review of practices introduced at other agencies and interviews with public and private industry stakeholders, the report catalogues practical strategies for improving estimating procedures and tracking cost data as well as the most important cost drivers of bridge construction. Analysis of KYTC …
