context_page_description: State Route 123 is a state highway in the Gifford Pinchot National Forest and Mount Rainier National Park east of Mount Rainier in the U.S. state of Washington. Located in the counties of Lewis and Pierce, the 16.34-mile long roadway extends through a heavily forested canyon from U.S. Route 12 to SR 410. First established as a branch of State Road 5 in 1923, the designation of SR 123 has changed from a branch of Primary State Highway 5 in 1937 to SR 143 during the 1964 highway renumbering and SR 123 in 1967. The northern terminus of the highway, Cayuse Pass, is closed annually and in late 2006, the Hanukkah Eve windstorm of 2006 washed out a 10.90-mile long segment of the roadway.
context_section_description: The history of SR 123 begins with the establishment of the Pacific Forest Reserve in 1893, which became the Mount Rainier Forest Reserve on in 1897, both included the area near the present highway. The Mount Rainier National Park was established as the fifth national park on March 2, 1907. The Mount Rainier National Forest Reserve became the Rainier National Forest in 1907 and Columbia National Forest in 1908. In 1923, a renumbering and restructuring of the state highway system occurred and a branch of State Road 5, later named the Cayuse Pass–Yakima branch, was added to the system. The northern terminus of the roadway at Cayuse Pass became U.S. Route 410 (US 410) during the creation of the United States Numbered Highways. The Columbia National Forest replaced the Rainier National Forest in 1933. The branch of State Road 5 became the Cayuse Pass branch of Primary State Highway 5 (PSH 5) in 1937. Between 1946 and 1959, a ski resort operated at Cayuse Pass. In 1949, the Columbia National Forest was renamed to the Gifford Pinchot National Forest to honor a pioneer of the same name. During the 1964 highway renumbering, the Cayuse Pass branch of PSH 5 became SR 143, an auxiliary route of SR 14. SR 14 became US 12 on June 20, 1967 and SR 143 became SR 123, while US 410 became SR 410. Since 1974, the Washington State Department of Transportation (WSDOT) has recorded the opening and closing dates of Cayuse Pass. The only season when the pass was not closed was between 1976 and 1977. The earliest closure was on October 7, 1996 and the earliest opening was on March 30, 1992. The latest closure was on January 4, 1990 and the latest opening was June 21, 1996. After the Hanukkah Eve windstorm of 2006, a 10.90-mile (17.54 km) long segment of SR 123, which is only 16.34 miles (26.30 km) long, was washed out and need reconstruction. Construction started on June 21, 2007 and the road reopened on September 28, 2007.
