A database for the 950 highway, railway, and pedestrian bridges on and over interstate highways I-5, I-205, and I-405 in western Washington State and northwestern Oregon was developed. The data recorded for each bridge will assist future database users in estimating bridge replacement costs, in performing finite element seismic analyses, and in other research and engineering activities. To develop this multipurpose database, multiple records were used for each bridge. The total number of records used for a given bridge was based on the larger of the number of spans, deck cross-sections, deck segments, supports, joints, soil borings, or bridge geometric datapoints. This technique of using multiple records per bridge permitted the storage of detailed information for a variety of bridges including several long viaducts in Seattle and Portland, some of which have 100 or more spans. This new bridge database structure should facilitate future development of comprehensive bridge inventories and databases for other highway networks in the United States and other countries.
