The data provide a small-scale cartographic rendition of proposed Washington State highways that are described in RCW 47.17 but have no active plans to be built. This dataset is part of the the linear reference system (LRS) used by Washington State Department of Transportation. This dataset is used: 1) for general-purpose base mapping; 2) as a Linear Referencing System (LRS); 3) for locating features on the proposed State Routes for which there are no active plans to be built by State Route Accumulated Route Mileage (dynamic segmentation). This dataset is a snapshot of the roadway system, effective 12/31/2022.
