资源简介：
The National Bridge Inventory (NBI) tracks the status, location, and structural health of all bridges on public roads in the U.S. Transportation agencies use the NBI to monitor infrastructure health, prioritize repairs and replacements, allocate Federal funding, and ensure public safety through standardized inspections. The links below provide highway bridges for all States in single annual files. The files are comma separated, and the text qualifier is a single quote.
