Each SR is symbolized with a single line whether or not the highway is divided. The data provide a small-scale cartographic rendition of Washington State highways. This LRS enables the use of dynamic segmentation to position features along the highway system according to the features' route measure position. State route numbers and accumulated route mileage values were obtained from the 2000 State Highway Log.
Nodes represent SR endpoints.
Also, nodes occur where SR's intersect with other SR's, with county boundaries, and with Washington State Department of Transportation region boundaries. The data set contains all of the mainline State Routes in Washington state. Positional accuracy has not been determined. Srclean.dgn contains state.dgn state routes depicted as single lines. In cases where highways are divided and intersect with other SR's, the intersection of the increasing sides were chosen for depiction.
