The National Highway System consists of roadways important to the nation's economy, defense, and mobility. The National Highway System (NHS) includes the following subsystems of roadways: Interstate - The Eisenhower Interstate System of highways, Other Principal Arterials - highways in rural and urban areas which provide access between an arterial and a major port, airport, public transportation facility, or other intermodal transportation facility, Strategic Highway Network (STRAHNET) - a network of highways which are important to the United States' strategic defense policy and which provide defense access, continuity and emergency capabilities for defense purposes, Major Strategic Highway Network Connectors - highways which provide access between major military installations and highways which are part of the Strategic Highway Network, Intermodal Connectors - highways providing access between major intermodal facilities and the other four subsystems making up the National Highway System. A specific highway route may be on more than one subsystem. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529838 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.

Users are advised to read the rest of the metadata record carefully for additional details. An inclusive work plan is developed including a project management plan, detailed work breakdown structure, project schedule, and performance metrics. The extent of this responsibility includes the arrangement of an initial meeting to facilitate coordination and planning, addressing any emerging matters or concerns, establishing clear roles and responsibilities, and establishing a platform for inquiries and responses among FHWA, FHWA resource center, and the State DOT representative. This involves processing technical corrections to the NHS geospatial nework, including updates, additions, or removals using the latest HPMS geospatial entity or ARNOLD geospatial entity as applicable. The main tasks involve the analysis and updating of the NHS network, and the utilization of custom geospatial tools for improved efficiency, such as carrying out various edits like updating route numbers, NHS classification, and geometries. Deliverable for this task include a finalized NHS network in digital format that include all technical corrections on existing NHS designation, adding new and approved NHS segments, technical correction to STRAHNET. data is updated as deemed necessary Edward Starks Federal Highway Administration (FHWA) Transportation Specialist 1200 New Jersey Ave. SE Washington DC 20590 United States edward.starks@dot.gov party that accepts accountability and responsability for the data and ensures appropriate care and maintenance of the resource
