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.

The NBI System is the collection of bridge inspection information and costs associated with bridge replacements of structurally deficient bridges on and off the NHS. This data is collected under the auspices of the National Bridge Inspection Standards (NBIS) as prescribed by law. The NBI System collects the information that is used to determine eligibility for NHS projects, performance measure reporting, NHS penalty determination, and reporting to Congress. It supports oversight of the NBIS through various report tools, and provides data reporting that supports agency strategic goals.

The National Bridge Inventory (NBI) is a database, compiled by the Federal Highway Administration (FHWA), with information of all the bridges and tunnels in the United States that have roads passing above or below them.This Excel Workbook contains a separate sheet for each year from 2016 to 2024 for the bridges on the National Highway System (NHS). The NHS includes the Interstate Highway System as well as other roads important to the nation's economy, defense, and mobility. It was developed by the Department of Transportation (DOT) in cooperation with the states, local officials, and metropolitan planning organizations (MPOs). TPB Staff downloads NBI data annually from the FHWA. TPB staff extracts NHS bridges in the TPB Planning Region, assigns a regional unique ID, calculates the bridge condition according to the federal rule, calculates the deck area, and summarizes the bridge condition data by jurisdiction to use as input to the federally-required Performance-Based Planning and Programming (PBPP) target setting and monitoring process.TPB staff use the geographic coordinates in the NBI file to calculate the latitude and longitude in decimal degrees. Several of the latitude and longitude coordinates were incorrectly located and have been updated by the TPB staff. Each bridge has a unique ID and can be linked to the annual files by the field PBPP ID.

Staff applied the final rule to the region’s latest bridge condition data for the TPB Planning Region. The data are reported per the required performance measures (good and poor conditions), see the rule and National Bridge Inventory Guide for more information.For more information:FHWA PBPP FHWA Transportation Performance Management TPM Frequently Asked QuestionsTPM Bridge Performance Measures

The NBI is an aggregation of State, Federal agency and Tribal government bridge and associated highway data submitted to and maintained by the Federal Highway Administration (FHWA). It contains inspection and appraisal data of more than 600,000 of the Nation’s highway bridges located on public roads in accordance with the National Bridge Inspection Standards. The NBI data is used to determine the condition of the Nation’s bridges that is included in reports to Congress, as a data source for executing various sections of the Federal-aid program which involve highway bridges, for assessing the bridge penalty provisions of Title 23 United States Code (U.S.C.) section 119, as the data source for the evaluation of bridge performance measures established in Title 23 U.S.C. section 150, to assist in the oversight of the National Bridge Inspection Program, as a data source to assess and inform the condition and funding needs of highway bridges, and for strategic national defense needs.

Bridges-Rail in the United States According to The National Bridge Inspection Standards published in the Code of Federal Regulations (23 CFR 650.3), a bridge is: A structure including supports erected over a depression or an obstruction, such as water, highway, or railway, and having a track or passageway for carrying traffic or other moving loads. Each bridge was captured as a point which was placed in the center of the "main span" (highest and longest span). For bridges that cross navigable waterways, this was typically the part of the bridge over the navigation channel. If no "main span" was discernable using the imagery sources available, or if multiple non contiguous main spans were discernable, the point was placed in the center of the overall structure. Bridges that are sourced from the National Bridge Inventory (NBI) that cross state boundaries are an exception. Bridges that cross state boundaries are represented in the NBI by two records. The points for the two records have been located so as to be within the state indicated by the NBI's [STATE_CODE] attribute. In some cases, following these rules did not place the point at the location at which the bridge crosses what the user may judge as the most important feature intersected. For example, a given bridge may be many miles long, crossing nothing more than low lying ground for most of its length but crossing a major interstate at its far end. Due to the fact that bridges are often high narrow structures crossing depressions that may or may not be too narrow to be represented in the DEM used to orthorectify a given source of imagery, alignment with ortho imagery is highly variable. In particular, apparent bridge location in ortho imagery is highly dependent on collection angle. During verification, TechniGraphics used imagery from the following sources: NGA HSIP 133 City, State or Local; NAIP; DOQQ imagery. In cases where "bridge sway" or "tall structure lean" was evident, TGS attempted to compensate for these factors when capturing the bridge location. For instances in which the bridge was not visible in imagery, it was captured using topographic maps at the intersection of the water and rail line. TGS processed 784 entities previously with the HSIP Bridges-Roads (STRAHNET Option - HSIP 133 Cities and Gulf Coast). These entities were added into this dataset after processing. No entities were included in this dataset for American Samoa, Guam, Hawaii, the Commonwealth of the Northern Mariana Islands, or the Virgin Islands because there are no main line railways in these areas. At the request of NGA, text fields in this dataset have been set to all upper case to facilitate consistent database engine search results. At the request of NGA, leading and trailing spaces were trimmed from all text fields. At the request of NGA, all diacritics (e.g., the German umlaut or the Spanish tilde) have been replaced with their closest equivalent English character to facilitate use with database systems that may not support diacritics. The currentness of this dataset is given by the publication date which is 09/02/2009. A more precise measure of currentness cannot be provided since this is dependent on the NBI and the source of imagery used during processing.
