Primary State Highway 5 (Washington) (Paperback)

High Quality Content by WIKIPEDIA articles! Primary State Highway 5, the National Park Highway, was a highway in the state of Washington, U.S.A., from 1937 to 1964. The National Park Highway was the primary north-south route through Washington, with the main (trunk) route of the highway extending from Seattle in the west through the Cascade Mountains in the east, terminating at PSH 3 in Yakima. PSH 5 was originally established as "State Road No. 5" by the state legislature in stages between 1905 and 1909. State Road No. 5 would later share its routing with portions of one major highways: US 12 for the Naches-Yakima section. State Road No. 5 was designated Primary State Highway 5 by the state legislature when it created the primary and secondary state highways systems in 1937. Highways in Washington were renumbered in 1964, and PSH 5 was removed from the state highway system. Today, PSH 5 is US 12, and other state routes.
