This service provides a quarterly snapshot of the North Carolina state-maintained road network centerlines. Here, the route network is divided into three layers with symbolized Route Classifications listed below.State Maintained RoadsInterstateUS RouteNC RouteSecondary RouteRampsRest AreasOther State Agency RouteState Maintained Roads - Primary RoadsInterstateUS RouteNC RouteState Maintained Roads - InterstatesInterstateNorth Carolina’s route network is comprised of Interstate, US, NC, Secondary Roads, Ramps, and non-state maintained and projected roads required for federal reporting purposes. Route attributes include Route Class, Route Qualifier, Route Inventory, Route Number, Route Name, and County name. The Route ID attribute is an 11-digit composite route number, the identifier for the Dominant Route. It uniquely identifies routes statewide and should be used as the route identifier when performing LRS analysis using route/milepost referencing.NCDOT adopted the road centerline based Linear Reference System (LRS) Network as it’s official Enterprise LRS, to which multiple road inventory attributes are referenced along measured routes throughout North Carolina. These routes are classified as either System or Non-System routes. System routes are routes within the state-maintained road network, and are comprised of Interstates, US Routes, NC Routes, Secondary Routes, Ramps, and Non-System Routes. Non-System routes are routes that are typically not maintained by NCDOT, but instead by a local agency (county, city or MPO/RPO). The local agency is the source for updating these Non-System routes in NCDOT’s LRS. The collection of routes, System and Non-System, is the NCDOT LRS Network referred to as MilePoint.MetadataThe metadata for the contained layers of the NCDOT State Maintained Roads service is available through the following links:NCDOT Route ArcsPoint of Contact North Carolina Department of Information Technology -Transportation, GIS UnitGIS Data and Services ConsultantContact information:gishelp@ncdot.govCentury Center – Building B1020 Birch Ridge DriveRaleigh, NC 27610Hours of service: 9:00am - 5:00pm Monday – FridayContact instructions: Please send an email with any issues, questions, or comments regarding the State Maintained Roads data.

An arc layer for visual representation of the state road system where each arc/record is split at each state maintained 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. This layer also includes some non-state maintained and projected roads that are required for reporting purposes. This layer also contains some additional routes to meet the Federal Highway Administration's (FHWA) data requirements for the Highway Performance Monitoring System (HPMS). HPMS is a national level highway information system that includes data on the extent, condition, performance, use, and operating characteristics of the Nation's highways. States are required to submit an HPMS report to FHWA annually. The additional routes include: Projected Routes - generalized locations of projected routes that will become part of the National Highway System (NHS) when they are built. Non-state maintained roads - generalized locations of roads that are owned by local, state and federal entities. Only non-state maintained roads that are eligible for federal aid are included. Currently there is no connectivity enforced between the state-maintained roads and the non-state maintained roads. Data quality is tracked using the revision document fields (REVDOC_TYP_CD and REVDOC_NUM). Legacy data are coded as not verified. These data are updated on an ongoing basis to improve data quality and the revision document fields are updated accordingly. As new data are added the geometry and spatial location are verified with the most current information available.

This service provides lines representing designated secondary routes in North Carolina where truck traffic with axle weights exceeding 13,000 pounds is prohibited by ordinance. These roads are shown as symbolized centerlines aligned to NCDOT’s route network. The Posted Route attribute value is the ordinance number; any value present indicates that the segment is part of the Posted Route system. Roads are posted to avoid damage to the roadway. As roads are improved and strengthened, they may be removed from this list.More information about North Carolina's Posted Roads can be found here:https://connect.ncdot.gov/resources/Asset-Management/Pages/Posted-Roads.aspxDetailed information regarding NCDOT ordinances, including truck restrictions, can be found here:https://connect.ncdot.gov/resources/safety/Pages/Safety-Ordinances.aspxA Posted and Restricted Roads lookup system can be accessed at this link:https://apps.ncdot.gov/PRR/RoadSearch.aspxMetadataThe metadata for the contained layer of the NCDOT Posted Roads Service is available through the following link:Posted RoutesPoint of Contact North Carolina Department of Information Technology -Transportation, GIS UnitGIS Data and Services ConsultantContact information:gishelp@ncdot.govCentury Center – Building B1020 Birch Ridge DriveRaleigh, NC 27610Hours of service: 9:00am - 5:00pm Monday – FridayContact instructions: Please send an email with any issues, questions, or comments regarding the Posted Roads data.

This service provides lines representing statewide road centerlines on publicly accessible roads segmented by a subset of road characteristics for the state road system. The state road system is comprised of Interstate, US, NC, Secondary Routes, and Ramps. Each arc/record is split where road characteristics change along a route. This data supports the Federal Highway Administration's (FHWA) data requirements for the Highway Performance Monitoring System (HPMS). HPMS is a national level highway information system that includes data on the extent, condition, performance, use, and operating characteristics of the nation's highways. States are required to submit an HPMS report to FHWA annually. This data also contains projected routes, generalized locations of routes that will become part of the National Highway System (NHS) when they are built. The non-system roads are consumed and conflated from authoritative sources, including local (i.e., county), state (i.e., parks) and federal (i.e., Forest Service) entities.This data is updated quarterly, usually February, May, August, and November.MetadataThe metadata for the contained layer of the NCDOT Road Characteristics Service is available through the following link:Public Road CharacteristicsPoint of Contact North Carolina Department of Information Technology -Transportation, GIS UnitGIS Data and Services ConsultantContact information:gishelp@ncdot.govCentury Center – Building B1020 Birch Ridge DriveRaleigh, NC 27610Hours of service: 9:00am - 5:00pm Monday – FridayContact instructions: Please send an email with any issues, questions, or comments regarding the Road Characteristics data.

This feature layer spatially represents DriveNC//NCDOT’s TIMS incident data feed by Road Condition. The TIMS Incidents data contains the general location of and details about incidents that affect or will affect travel on roads maintained by the North Carolina Department of Transportation.This hosted feature layer view is intended for public viewing.NCDOT TIMS Incidents Points - Contains a point reference for all incidents, point and line.NCDOT TIMS Incidents Lines - Lines representing linear incidents. Generally, only select incidents types and road closed conditions will be represented as lines. A point feature will represent the same incident.This data includes all incidents including those recorded on concurrent routes. To remove these from the data, filter where "CreatedFromConcurrent = False".The data is provided through an automated routine that pulls data from the TIMS geojson feed every 5 minutes. Note that the data may disappear for a few moments while being refreshed.The feature layer contains all incidents; current and future. To only view current incidents in your web map, create a filter using the "StartDate" field. For example, filter by Start Date "in the last" 6 years. Note: DateTime fields are in UTC (as indicated in the field name). Text fields contain data/time values in Eastern Time.
