Safe and Cost-Effective Reduction of Load Postings for South Carolina Bridges

A portion of South Carolina’s transportation infrastructure contains an aging bridge inventory with bridges that were designed for lower traffic loads (i.e., H-10 and H-15 load designs). For many of these bridges, it is difficult to assess the capacity of substructure elements, and rehabilitation methods are needed to address damage to caps and superstructure elements. Currently, an estimated 300 bridges in the state have load postings due to these structural and design considerations. To address this need, this research strives to: (1) identify and classify common load rating issues associated with families of bridges; and (2) address these issues through improved and more appropriate load rating analysis procedures and/or cost-effective rehabilitation strategies.
