Bridge inventory information collected by each State transportation department, Federal agency and Tribal government is reported to the Federal Highway Administration (FHWA), as requested, in accordance with the National Bridge Inspection Standards (NBIS) reporting requirements (23 CFR 650.315). The resulting information is maintained in the National Bridge Inventory (NBI) database, which enables state-level and national-level analyses and reporting, supports Federal funding programs, and facilitates the identification of freight and defense-critical corridors and connectors. By having a complete and thorough inventory, an accurate report can be made to the Congress on the number, condition, and performance of the Nation’s bridges. The data also support FHWA’s programs, and the efforts of the Military Surface Deployment and Distribution Command (SDDC) Transportation Engineering Agency (TEA).

The Manual for Bridge Evaluation (MBE), produced by the American Association of State Highway and Transportation Officials (AASHTO), discusses the various items of information that are to be recorded as part of bridge inspections. That manual and the FHWA’s Bridge Inspector’s Reference Manual (BIRM) discuss inspection procedures and the preparation of detailed reports about bridge members. These reports are the basis for reporting values for many of the data items shown in these specifications.
The proper assessment of element-level bridge conditions and the ability to use condition data to efficiently and effectively manage bridge inventories are cornerstones to providing a safe and efficient highway transportation system. These specifications include the description of bridge condition rating data for both component-level (deck, superstructure, substructure, and culvert) and element-level evaluation.
The reporting of inventory data for all highway bridges subject to the NBIS, and their related features, are based on the definitions, explanations, and data items supplied in these specifications and supplemented by the NBIS, AASHTO Manual for Bridge Element Inspection (MBEI), MBE, and BIRM. State transportation departments, Federal agencies, and Tribal governments use the data items and instructions in these specifications when reporting NBI data to FHWA. These agencies are responsible for the accuracy and completeness of the reported data, using agency data quality control and quality assurance procedures. Agencies may use their own data item names and codes for their agency inventory, but must report NBI data to FHWA in accordance with these specifications.
It is expected that coordination is needed between various personnel, in various infrastructure disciplines of an agency, to obtain and report the data in accordance with these specifications, and does not solely rely on bridge inspection personnel.
All possible combinations of actual bridge characteristics may not be addressed in these specifications. Consult with the local FHWA division office contact for an acceptable solution when a special situation is encountered that is not addressed by these specifications.
