A Context For Common Historic Bridge Types

This study covers bridges built in the United States through 1955, up to the year of the passage of the Federal Aid Highway Act of 1956, which created the Interstate Highway System. It is intended to provide assistance to practitioners with assessing the historic significance of bridge types within the context of the United States, and can improve the significance evaluation process through providing a picture of the bridge types that are very common and those that are much less common, as well as providing an assessment of the technological and historical significance of the individual types. The study lays the foundation for evaluating whether a bridge to be removed requires additional documentation. (It is important to note that the study does not address one-of-a kind and other rare historic bridges.)
