State Highway Log
The State Highway Log is annually published and designed to provide a record of current highway system information and a source for computing distances between major points.
The State Highway Log contains roadway data and mileage statistics for more than 7,000 miles of Washington state highways and includes such items as: the number of lanes; the length and width of turn lanes; shoulder, roadway and median widths; roadway surface pavement type; legal speed limits; and state route milepost locations for such physical features as intersecting roads, bridges and underpasses, county and corporate limits and on/off ramps.
Our Linear Referencing Storymap will help you learn about how we use unique route id and milepost information to describe locations on the State Highway system.
The technology used to manage the State Highway Log data limits the accessibility of the files provided here. Contact roadway@wsdot.wa.gov for accessible format versions of the information found in these State Highway Log documents.

Slow down – lives are on the line.
Excessive speed was a top cause of work zone collisions in 2024.
Phone down, eyes up.
Work zones need our undivided attention.
It's in EVERYONE’S best interest.
96% of people hurt in work zones are drivers, their passengers or passing pedestrians, not just our road crews.
