1964 state highway renumbering (Washington)

Highway renumbering in Washington July 2025 December 2015 x70px x70px 1964 state highway renumbering Interstate X (I-X) U.S. Route X (US X) State Route X (SR x) WA The 1964 state highway renumbering was a reorganization of state highways in the U.S. state of Washington. The new system, based on sign routes (SR, later changed to state routes), replaced the primary and secondary highway system implemented in 1937. It was first signed in January 1964 and codified into the Revised Code of Washington in 1970. History The former numbering system of primary and secondary state highways, using lettered suffixes and unnamed branches, created confusion for motorists as the system expanded. The system also ignored, or conflicted with, the federal highway system and the then-developing Interstate Highway System.Hauptli Jack July 1, 1962 2B or not 2B—Maybe it is 2A 3 The Seattle Times The state highway department originally planned for a major highway renumbering in 1957, expanding on the existing primary and secondary system with numbers as high as 59, but serious consideration of a full-scale renumbering began in 1962.March 1957 Plan for Renumbering State Highways Goes to Legislature 19–20 Washington Highways Washington State Department of Highways 6 9 29654162 https://cdm16977.contentdm.oclc.org/digital/collection/p16977coll1/id/2468/ WSDOT Library Digital Collections September 12, 2018 It had the specific goal of replacing letter suffixes with two- and three-digit numbers, which would not repeat or conflict with each other or with federal route numbers.September 18, 1962 New Numbers For Highways In-State Urged 4 The Seattle Times Associated Press In 1963, the Washington State Legislature passed a law authorizing the creation of a new state highway numbering system under the direction of the Washington State Highway Commission.March 9, 1963 Session Laws of the State of Washington, 1963 Chapter 24: Highways—Routes—Numbering 316–318 http://leg.wa.gov/CodeReviser/documents/sessionlaw/1963c24.pdf Washington State Legislature June 2, 2017 The law came in response to confusion experienced by tourists visiting during the 1962 World's Fair, held in Seattle.Hauptli Jack February 23, 1964 Highway Department Plays The Numbers Game! 10–11 The Seattle Times The highway commission approved its numbering plan on June 19, 1963, using even numbers for east–west routes and odd numbers for north–south routes; primary routes would have lower numbers, while secondary routes would use the first digit to indicate its parent route.Smith Lee January 12, 1964 Days Numbered For State Highway Daze—New Designations Scheduled 14 Seattle Post-Intelligencer Associated PressJune 19, 1963 Renumbering Of Roads Set 24 The Seattle Times Associated Press Federal highways, including Interstate highways, would retain their designations and be incorporated into the system.June 19, 1963 Renumbering of roads set 24 The Seattle Times Associated Press The new numbering system took effect on January 15, 1964,January 7, 1964 New Road Numbering Is Started 5 Walla Walla Union-BulletinHannula Don November 29, 1963 Just Ignore Signs On New Freeway 2 The News Tribune https://www.newspapers.com/clip/98405565/just-ignore-signs-on-new-freeway/ Newspapers.com March 25, 2022 and new signs were posted at a cost of $115,000.January 16, 1964 Times Troubleshooter: New Route Numbers 10 The Seattle Times Route renumbering New Sign Route numbers New numberPrahl C.
