The bridge inventory data were obtained from Caltrans Structure Maintenance and Investigations (SMI) Database, as of April 15, 2015. SMI performs bridge inspections in accordance with federal regulations on over 12,000 State Highway bridges and approximately 12,200 bridges owned by local government agencies. Caltrans bridge inspectors are responsible for maintaining the safety and integrity of over 24000 bridges owned by the State of California and California's local government agencies.

The state bridge dataset consists of bridge attributes collected for the purpose of reporting to Federal Highway Administration. This data was pulled on the date indicated by the file. The data was extracted from the SMI database and have been in the process of being modified when it was extracted. For official data attributes for each bridge, use the signed and stamped Bridge Inspection Reports stored in BIRIS.
