WSDOT - Highways of Statewide Significance

This is an extract from the State Highway Log that shows Highways of Statewide Significance along State Routes. State Route identifiers and locations based on State Route Mileposts and Accumulated Route Mileage are also included for geographic reference and for use with the Washington State Department of Transportation's 24k and 500k Linear Referencing Systems.本数据集为《州级公路日志》的节选内容，收录了沿州级公路（State Routes）布设的全州重要性公路（Highways of Statewide Significance）路段。数据集同时包含基于州级公路里程桩（State Route Mileposts）与累计路线里程（Accumulated Route Mileage）的州级公路标识与位置信息，可用于地理参照，同时适配华盛顿州运输部（Washington State Department of Transportation）的24k与500k线性参考系统（Linear Referencing Systems）。
