Washington State Route 8 west of the US 101 interchange, and is scheduled to begin this season and last 2 months. In 2010, WSDOT aims to rebuild the columns that support the SR 8/US 101 interchange and reduce the risk of failure in an earthquake, such as the 2001 Nisqually earthquake. Washington State Route 8 State Route 8 (SR 8) is a state highway in Grays Harbor and Thurston counties, of the U.S. state of Washington. It extends from U.S. Route 12 (US 12) in the city of Elma, east to an interchange with US 101 about northwest of the state capital, Olympia. SR
Washington State Route 8 Washington State Department of Transportation (WSDOT) replaced the previous system of Primary and Secondary Highways with a new system called State Routes, which is still in use today. Later in 1967, US 12 was extended from Lewiston, Idaho westward to Aberdeen. It was approved on June 20, 1967, and it replaced the route of US 410, therefore making the highway obsolete. Since US 12 used the all-weather White Pass and SR 8 from Elma to Grand Mound, and US 410 used Chinook Pass, which was closed during the winter, US 12 bypassed US 410 and what is now SR 8.
