Retrofit Design of Seismically Deficient Bridges on and Over the Interstates and Parkways in Western Kentucky

Over 6,600 Kentucky bridges will experience ground accelerations between 0.10 g and 1.00 g during the American Association of State Highway and Transportation Officials (AASHTO) Maximum Credible Earthquake. These structures are being evaluated as part of another study (SPR 24-656) to identify bridges that require retrofits to increase their capacities and meet the demand based on AASHTO’s 2022 Specifications. Most bridges on and over the interstates and parkways in Western Kentucky are expected to exhibit deficiencies ranging from inadequate seat support to lack of foundation capacity. Ongoing research, however, is not developing a retrofit design. Kentucky Transportation Cabinet (KYTC) can use project findings to generate construction cost estimates and prioritize funding for retrofit or replacement of seismically vulnerable bridges.
