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: ~ 501 MB, Uncompressed SHP file size: ~ 2.10 GB​

MPO/RPO Boundaries

Polygons depicting the various MPO and RPO boundaries, covering the entire state of North Carolina. Existing MPOs expanded their Metropolitan Planning Areas (MPAs) to include all territory in Census 2020 UZAs. All boundary adjustments are approved by the Governor(s) and submitted to the FHWA Division Office(s). The MPA boundaries include the entire UZA boundary identified in the 2020 decennial Census and the contiguous geographic area likely to become urbanized within 20 years. RPOs were created for transportation planning in rural North Carolina areas not within an MPO.

Release: Third Quarter 2021 Release
