Statewide System & Non-System Road Arcs
An Arc Layer for visual representation of the state road system where each arc/record is split at each road intersection. This is a digital file of the North Carolina Department of Transportation's Linear Referencing System that represents the routes and attributes of the NCDOT state road system. The state road system is comprised of Interstate, US, NC, Secondary Routes, and Ramps and all non-state maintained and projected roads required for reporting purposes. Uncompressed GDB file size: ~391 ​MB



Release: 2024 End of Year Release
Road Characteristics Arcs
An Arc Layer for visual representation of a subset of road characteristics for the state road systems. Each arc/record is split where road characteristics change along a route. This is a digital file of the North Carolina Department of Transportation's road inventory database that represents a subset of road characteristic attributes of the NCDOT state road system. The state road system is comprised of Interstate, US, NC, Secondary Routes, and Ramps. This layer also includes all non-state maintained and projected roads that are required for reporting purposes. Uncompressed GDB file size: ~ 544 MB​

MPO/RPO Boundaries

Polygons depicting the various MPO and RPO boundaries, covering the entire state of North Carolina. These planning area boundaries, called Metropolitan Planning Areas (MPAs) for MPOs or planning area boundaries for RPOs, represent the geographic areas likely to become urbanized within 20 years. They are the areas that MPOs and RPOs are responsible for conducting long range transportation planning.​

Smoothed 2020 Census Urbanized Boundaries

Polygon layer representing the smoothed boundaries for the 2020 Census urban areas in North Carolina. The boundaries were originally generated by the US Census Bureau and have been adjusted (smoothed) by the North Carolina Department of Transportation, in cooperation with North Carolina’s Metropolitan Planning Organizations. Data has been republished as part of 2024 End of Year Quarter Publication to include updated 2023 population estimates.
