State Route 6 (SR 6) is a 51.37-mile (82.67 km) long state highway in Pacific and Lewis counties in the U.S. state of Washington. The highway, which extends from U.S. Route 101 (US 101) in Raymond east to Interstate 5 (I-5), co-signed with US 12, in Chehalis. Major communities located on the highway include Raymond, Pe Ell, Adna and Chehalis. The first state highway that used the current route of SR 6 was State Road 19, established in 1913. State Road 19 became State Road 12 in 1923, which became Primary State Highway 12 (PSH 12) in 1937. In 1964, PSH 12 became SR 6 and since, three minor construction projects have been arranged, only two have been completed.
