State highways in Washington Interstate US State Scenic Pre-1964 1964 renumbering Former

The U.S. state of Washington has over 7,000 miles (11,000 km) of state highways maintained by the Washington State Department of Transportation (WSDOT). The highway system is defined through acts by the state legislature and is encoded in the Revised Code of Washington as State Routes (SR). It was created in 1964 to replace an earlier numbering scheme and ratified by the state legislature in 1970. The system's 196 highways are almost entirely paved, with the exception of a gravel section on SR 165.

The state's Interstate and U.S. Highways are also defined as part of the state route system, but are omitted from this list.
