GIS Unit is pleased to announce release of the GIS Data layers on the GIS unit
webpage specified below for Second Quarter 2022. Future Quarter releases for this year are tentatively scheduled
for the following months: August and November 2022 and February and May of 2023.
1. The NCDOT Rail Division
data for Crossings, Track and Facility locations have been updated.
2. The Road
Characteristics, Road Arcs and Road Routes layers are updated and includes both
System and Non-System routes. The HighwayExit point feature class is
included in the Road Characteristics File Geodatabase.
3. The NCDOT Structure Locations for Bridge data has been updated.
4. The following listed boundary layers have been updated: County Boundary Shoreline, County Boundaries, DOT Division Boundary
Route Data Updated this Quarter:
This layer is a visual representation of public roads in North Carolina. State maintained roads are current through March 2022 for changes by NCDOT Petitions and Municipal Agreements processes.
All represented non-system roads are sourced from local government datasets and are reflective of the last uploaded datasets. Non-system roads specifically updated this quarter: Alamance, Brunswick,
Buncombe, Cumberland, Durham, Forsyth, Iredell, Johnston, Mecklenburg,
Mitchell, and Northampton counties.
For more detailed information about available NCDOT data and possible known data issues, please
see document NCDOT GIS Unit Announcements.
The Structures layer contains all features previously found in the NCDOTBridgeLocations shapefile, plus 3 types of signs currently maintained by the NCDOT Structures Management Unit.
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
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
Review the following before downloading the Road Characteristics files:
Railroad layers from the NCDOT Rail Division including track, crossings and facility data.
The track dataset includes current in-service rail track as well as NCDOT-owned rail track. The crossings dataset includes public rail crossings , both at grade and grade separated. The facility dataset includes Amtrak station, Amtrak bus stops, yards, intermodal facilities and transload locations. The track, crossing and facilities layers can be downloaded individully as shapfiles or as a single geodatabase.

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
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.
The LRS Integration Guide is available to assist users with the LRS and referencing methods in the "Road Data" layers.
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.
Polygon layer representing county boundaries for use in depicting the boundaries with a shoreline.
Polygon layer representing the NCDOT Division boundaries.
Polygon layer representing County Boundaries developed by North Carolina Geodetic Survey to facilitate planning, siting, and impact analysis in the 100 individual counties of North Carolina.
Polygon layer primarily consisting of municipalities that participate in the Powell Bill.
