BeginStateRouteMilepost
A logical number, assigned by a Linear Referencing Method, to the beginning of a roadway segment along a State Route. This value will always match the Accumulated Route Mileage value unless there has been a realignment or jurisdictional transfer which changes the length of a route.

BeginAccumulatedRouteMile
The measure of a point at the beginning of a roadway segment along the length of a route in which the distance is measured as an accrual of mileage from the beginning of the route. The Accumulated Route Mile Begin may define the starting point for a business activity or measurement. For example, project location or roadside event.

The data contained within the State Highway Log is collected and updated using contract plans, field reviews and information provided by numerous WSDOT Regional and Headquarters offices as well as other county and city sources over the course of a year. This data may have changed since the publication date. Only those records that have a RouteID (Route Identifier) found in the Washington State Highways at 24K Linear Referencing System can be graphically placed as events. RouteIDs that have been added or revised since the completeness date of the LRS will not place, nor will RouteIDs for road features not carried by the LRS.
Values were obtained from the Transportation Information and Planning Support (TRIPS) database.
Positional accuracy of this data set has not been determined
The Roadway Datasets are extracted from the Roadway Datamart using SQL queries and stored as Excel spreadsheets. These spreadsheets are placed as events on the StateRouteLRS data layer using the ArcGIS Display Route Events function with route names that include the direction of travel ( i, d). The event layers are converted to feature classes and loaded into an SDE database for publication.
