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

Since the 1964 state highway renumbering, which established the current state route system, the Washington State Department of Transportation has decommissioned some state routes. Once a highway has been decommissioned, the highway is turned over to the local county or city that it is in, they are then responsible for all maintenance on the former highway. All former highways are codified in Washington law under the Revised Code of Washington, chapter 47.17, section 420.^{[ citation needed ]}

Other highways during the transition between the 1964 renumbering and codification of the new system in 1970 are not listed here.

Following the completion of the North Cascades Highway in 1972, SR 20 was extended east to form a cross-state route under a single number. SR 30 and SR 294 were decommissioned in 1973 and incorporated into the extended highway, which became the state's longest. ^{[4] [5]}

State Route 110 was established in 1967 as SSH 1F, a short connector between Chuckanut Drive (SR 11) and I-5 (formerly PSH 1) that had been planned to be built. ^[10] The route was intended to provide automobile and truck access to the freeway from the Fairhaven neighborhood and nearby industrial areas, bypassing residential areas in Bellingham. ^[11] The city government had proposed the highway in 1966 and studied several routings for the 1.2-mile (1.9 km) highway, ^[12] ultimately recommending route that generally followed the former Fairhaven and Southern Railroad; ^[13] state highway engineers recommended against a limited-access road due to the corridor's development potential. ^[14]

The state government approved plans in 1969, despite local opposition, and the highway was named the Valley Parkway by the city government in January 1972. ^{[15] [16]} Construction began later that year and the highway opened to traffic in November 1972 at a cost of $615,479. ^{[17] [18]} SR 11 was routed onto the new highway upon its completion as part of a provision added by the state legislature in 1971. ^{[18] [19]} SR 110 was repealed and decommissioned in 1975; ^[20] the designation was later assigned to a separate route in 1991. ^[21]
