The Kentucky Transportation Cabinet (KYTC) has previously used sufficiency ratings to prioritize bridge projects. These ratings weighted three factors – structural evaluation, design obsolescence, and asset importance – to determine eligibility for federal funding. But this approach was flawed because it omitted factors which can justifiably be used to prioritize projects. Additionally, there was no way to combine risk and condition factors in prioritization, which inhibited KYTC’s ability to rank the relative importance of its assets to the overall network. Currently, input from district personnel informs bridge project prioritization; however, the Cabinet wants to integrate a Bridge Importance Index into the process, an approach several other states have adopted. The outcome of this project will be an index that synthesizes data on bridge condition and other factors to help KYTC make project prioritization decisions as well as incorporating such information into risk-based asset management. |
