National Transportation Atlas Database
The National Bridge Inventory dataset is as of June 27, 2024 from the Federal Highway Administration (FHWA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The data describes more than 615,000 of the Nation's bridges located on public roads, including Interstate Highways, U.S. highways, State and county roads, as well as publicly-accessible bridges on Federal and Tribal lands. The inventory data present a complete picture of the location, description, classification, and general condition data for each bridge. The element data present a breakdown of the condition of each structural and bridge management element for each bridge on the National Highway System (NHS). The Recording and Coding Guide for the Structure Inventory and Appraisal of the Nation's Bridges contains a detailed description of each data element including coding instructions and attribute definitions. The Coding Guide is available at: https://doi.org/10.21949/1519105.
Data in the NBI is used to meet legislative reporting requirements and provide bridge owners, the Federal Highway Administration (FHWA) and the general public with information on the number and condition of the Nation’s bridges.

Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
23 CFR 650 Subpart C (National Bridge Inspection Standards) requires that States, federal agencies, and tribal governments maintain an inventory of all public highway bridges within their jurisdiction, and submit that data to the Federal Highway Administration (FHWA) annually or as requested. Bridges that are not federally or tribally owned (i.e. local or privately owned bridges) are submitted by the State. Regulation requires data to be submitted March 15th of each year, though there may be updates throughout the year. The dataset is archived on December 31st and typically published in January.
