Description:

Abstract:

This dataset represents county roads open to the public in Washington State as listed in the County Road Administration Board (CRAB) Road Log compiled as a GIS Linear Referencing System (LRS) using County Road Numbers and county milepost values. Route measure values are valid as of 12/31/2024. Please direct questions about this dataset to: TransportationGISDataSteward@wsdot.wa.gov.

Purpose:

This dataset is used for general-purpose mapping and as a linear referencing system.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Road numbers and milepost values were obtained from the CRAB Road Log and checked against county maps where available. Orthoimagery was used for determining route alignments.

Logical_Consistency_Report:

This dataset represents County Roads open to the public with county milepost values as shown in the CRAB Road Log.

Completeness_Report:

This dataset contains all county roads open to the public as of the dataset's calendar date under time period.
