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: ~302 ​MB​, Uncompressed SHP file size: ~ 1.11 GB​

Release: Second Quarter 2021 Release
Statewide System & Non-System Road Routes

A Route Layer for visual representation of attributes stored by County/Route/Milepost linear reference. 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: ~ 176 MB, Uncompressed SHP file size: ~ 477 MB​

Release: Second Quarter 2021 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: ~ 389 MB, Uncompressed SHP file size: ~ 1.78 GB​

Smoothed 2010 Census Urbanized Boundaries

Polygon layer representing the smoothed boundaries for the 2010 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.　  

Release: First Quarter Annually
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 2010 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 2010 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: First Quarter Annually
