A methodology for a span-based approach to bridge network characterization is presented. Spans are organized and evaluated by using five distinguishing factors, namely, size, type of service, continuity, superstructure material, and design type. Emphasis is placed on making the methodology useful for a wide range of bridge management tasks. Network characterization is pursued through the aggregation of spans with similar characteristics into "span families". The historical trends of various condition measures are evaluated for bridges, spans, and families of spans, and preliminary network-level trends are investigated. The methodology is applied for the case of the New York State Thruway bridge network. It is concluded that the decomposition of bridges into their constituent spans and the classification of spans into families provide a viable approach to the development of detailed condition prediction models.
