Download NBI Element Data
The following datasets represent bridge element data submitted annually to FHWA by the States and Federal agencies as required by 23 U.S.C. 144 and the Specification for the National Bridge Inventory Bridge Elements. Each dataset is submitted in the spring, and may be corrected or updated throughout the year. The data is considered final and is published on this website at the end of each calendar year.
Collection of element level bridge condition data is required for all bridges on the National Highway System (NHS). Collection of element data is optional for bridges that are not on the NHS. All element data submitted is included in these downloads.
