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.

Slow down on ice and snow.

It's easier to skid or lose control traveling at higher speeds. Give yourself more time to stop.

Carry chains, practice installing them.

Winter conditions could mean chains are required on your route. Practice putting them on your vehicle ahead of time.

Pack your winter car kit.

Carry extra supplies like warm clothing, ice scraper and brush, jumper cables and other emergency items.
