System description

See also: List of state routes in Washington

All state highways are designated by the

U.S. Route 101 Alternate.[1][2] WSDOT has also defined some spurs that mainly serve to provide full access between intersecting routes.[a]

Although most state highways as defined by law are open to traffic,

public highways".[13][14][15]

Most state routes are numbered in a grid, with even-numbered routes running east–west and odd-numbered routes running north–south.

SR 41 are extensions of highways in adjacent states.) Three-digit routes (and SR 92 and SR 96) are usually numbered by taking the first one or two digits of a route it connects to and adding another digit or two.[16] In some cases, instead of using the two-digit route's actual number, a number that would fit the grid is used instead.[17]
Three-digit routes have been numbered as follows:

History

Main article:
History of Washington's state highway system
Washington's first connected state highway system, 1913

After passing several early laws designating state roads starting in 1893, the

Chuckanut Drive and a road around the west side of the Olympic Peninsula.[18] Under a 1909 law, the State Highway Board surveyed a connected network of proposed state roads,[19] The legislature added most of these routes to the state highway system in 1913, when they formed a two-tiered system of primary and secondary roads. Primary roads were completely controlled by the state, including maintenance, and received only names, while secondary roads kept their numbers and county maintenance. Unlike the earlier state roads, these primary roads mostly followed existing passable county roads.[20][21][22]

A 1923 restructuring of the system reassigned numbers to almost all the primary state highways,

final renumbering[26][27] was authorized by law in 1963 and posted in January 1964, when new "sign route" numbers were assigned that matched the inter-state systems and otherwise formed the present grid. Until 1970, these numbers coexisted with the older primary and secondary state highways, when the legislature adopted the sign route numbers as "state routes",[citation needed] finally eliminating all vestiges of the 1905 numbering.[c]

The state legislature adopted new standards for designating state highways in 1990, following a three-year study from the Road Jurisdiction Committee. Among the changes were recommending highways serving state parks and ferry terminals be added to the system.[28] A major restructure was passed by the legislature in 1991 and took effect on April 1, 1992.[29]
