The dataset exists to serve the Federal Highway Administration (FHWA) needs in highway planning, policy analysis, and visualization of the NHS database. It is intended for use in understanding and managing the National Highway System, which includes roadways crucial to the nation's economy, defense, and mobility. Also, the dataset is being used by the US DOT to reflect the FHWA-approved technical correction for NHS and STRAHNET.
