Primary State Highway 1, the Pacific Highway, was a highway in the state of Washington, U.S.A., from 1937 to 1964. The Pacific Highway was the primary north-south route through Washington, with the main (trunk) route of the highway extending from Blaine in the south through Vancouver in thesouth, terminating at the Oregon state line.
PSH 1 was originally established as "State Road No. 1" by the state legislature in stages between 1905 and 1909. State Road No. 1 would later share its routing with portions of two major highways: US 99 for the state road's entire length and the I-5 at various portions. State Road No. 1 was designated Primary State Highway 1 by the state legislature when it created the primary and secondary state highways systems in 1937. When commissioned, PSH 1 coincided with U.S. Route 99 for all of its length. By the early 1940s, US-99 between Everett and Tacoma had been rerouted onto the more western alignment currently used by SR 99; the western route was initially designated Alternate US-99 and then, in 1964, SR 99.
In South Everett, PSH 1 turned southwest and followed Everett Mall Way on a diagonal course through the South Everett Commercial Area, turning south on Evergreen Way. Then stays on SR 99 until Fife. While in Fife PSH 1 becomes the Pacific Hwy. SR 99 goes onto I-5
Highways in Washington were renumbered in 1964, and PSH 1 was removed from the state highway system. Today, PSH 1 is I-5, SR 99, and other state routes.
