    • Adjusted Urban Areas

    Metadata Updated: July 17, 2025

    The 2020 Adjusted Urban Areas dataset was compiled on December 31, 2020 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 2020 Federal Highway Administration (FHWA) Adjusted Urban Areas layer delineates the boundaries of adjusted urban areas as defined by the FHWA, based on the 2020 U.S. Census urban area boundaries. This nationwide geospatial dataset represents urbanized areas that have been modified through coordination between FHWA Division Offices, State Departments of Transportation (DOTs), and Metropolitan Planning Organizations (MPOs), in accordance with FHWA's Urban Area Boundary Adjustment guidelines. These boundaries are used for transportation planning and programming, eligibility determinations, and analysis purposes related to Federal-aid highway programs.
