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.

The technology used to manage the State Highway Log data limits the accessibility of the files provided here. Contact for accessible format versions of the information found in these State Highway Log documents.

Traction tires are a special type of tire

manufactured with at least 1/8 of an inch tread. Traction tires are usually marked with a mountain/snowflake symbol, the letters M+S or “All Season.”

Carry chains, practice before leaving

Requiring chains keeps traffic moving during storms rather than closing a pass or roadway.

Prep your car. Fill up your gas tank,

pack jumper cables, ice scraper, warm clothing, snacks and water.
