In 1963, a law was passed authorizing a new numbering for sign routes. In 1970 the legislative definitions were changed to use the sign route numbers but renamed state routes. Those definitions, with amendments, are still in use today.
In 1964, the Washington State Department of Transportation (WSDOT) created a new numbering system, the State Route system, out of the existing Primary State Highways (PSH) and Secondary State Highways (SSH) system. The new system, called State Routes or Signed Routes (SR), consolidated and created a more organized and systematic method of numbering the highways within the state. The system also introduced accordance with the new Interstate Highway system, with the creation of Interstate 5 within the state.
Famous quotes containing the words state and/or highway:
“A multitude of causes unknown to former times are now acting with a combined force to blunt the discriminating powers of the mind, and unfitting it for all voluntary exertion to reduce it to a state of almost savage torpor.”
—William Wordsworth (1770–1850)
“The improved American highway system ... isolated the American-in-transit. On his speedway ... he had no contact with the towns which he by-passed. If he stopped for food or gas, he was served no local fare or local fuel, but had one of Howard Johnson’s nationally branded ice cream flavors, and so many gallons of Exxon. This vast ocean of superhighways was nearly as free of culture as the sea traversed by the Mayflower Pilgrims.”
—Daniel J. Boorstin (b. 1914)
