I've grown up in this area and thought this series would be fun. I use this road at least once a day and sometimes more. Make sure you get the number and letter from each of the other caches. You will be collecting 8 different ones for the coords to the final. Enjoy. State Route 507 (SR 507) is a Washington state highway in Lewis, Thurston and Pierce counties that extends 43.52 miles (70.04 km) from Interstate 5 (I-5) and U.S. Route 12 (US 12) in Centralia to SR 7 in Spanaway. The highway also intersects SR 510 in Yelm and SR 702 in McKenna. The first appearance of the roadway on a map was in 1916 and since, two highways, Secondary State Highway 5H (SSH 5H) and SSH 1N, were established on the current route of SR 507 in 1937 and 1943. They both became SR 507 during the 1964 highway renumbering. The first appearance of a highway located on the current route of SR 507 was in a 1916 map of the Chehalis area. A road extending northwest from Centralia to Roy was shown serving the communities that SR 507 currently serves. In 1937, during the creation of the Primary and secondary highways, Secondary State Highway 5H (SSH 5H) was established, running from Tenino to Spanaway. A section of 507 houses the Tenino Downtown Historic District. In 1943, SSH 1N, running from Centralia to Tenino, was created. In 1964, a highway renumbering replaced both SSH 5H and SSH 1N with SR 507. A left turn lane was installed at the Yew Street intersection east of the Interstate 5 (I-5) and U.S. Route 12 (US 12) interchange in Centralia on 24 May 2007. SR 704, when completed, is predicted to reduce congestion on SR 507.
