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.
