Road conditions feature layers

NDDOT ArcGIS feature layers that provide real-time road condition information via polylines for select roadways within the State of North Dakota.

NDDOT provides this data through their Road Conditions Reporting System (RCRS) service, split across two geographic regions to improve performance and data management. North Dakota uses a dual-layer system covering different road directions (north & east, south & west).

  • Base Service URL: https://gis.dot.nd.gov/arcgis/rest/services/external/rcrs_dynamic/MapServer
  • Layer 31 (N,E): https://gis.dot.nd.gov/arcgis/rest/services/external/rcrs_dynamic/MapServer/31
  • Layer 32 (S,W): https://gis.dot.nd.gov/arcgis/rest/services/external/rcrs_dynamic/MapServer/32
  • Update frequency: realtime by operator
  • Source endpoint type: ArcGIS REST
  • Availability: Public
  • Source geometry: esriGeometryPolyline
  • Projection: EPSG:3857
  • Supported Query Formats: JSON, geoJSON, PBF

Both layers share identical schemas but contain segmented data for different roadway directions in North Dakota.
