Bridges are among the most essential and important transportation assets. Since they comprise various ages, configurations, and structural features, and are exposed to different environmental conditions and service loads, evaluating their performance and managing their safety and serviceability is challenging. A number of state departments of transportation (DOTs) and federal agencies have developed and implemented several bridge performance measures in the past several decades. This study explores existing bridge performance measures through an extensive literature review, presents their concepts and applications, and discusses their unique features. The measures include metrics proposed/implemented by state DOTs, the Federal Highway Administration (FHWA), the National Cooperative Highway Research Program (NCHRP), and other researchers in the U.S. and around the world. Results of this study will assist stakeholders in choosing appropriate metrics for various performance assessment and management purposes. In addition, identified gaps in existing metrics can guide in the development of efficient performance measures for bridge systems.
