State Route 109 (SR 109) is a Washington state highway in Grays Harbor County. Beginning at its terminus at U.S. Route 101 (US 101) in Hoquiam, the highway travels west to intersect SR 115 near Ocean Shores and then turns north to continue along the Pacific coastline, terminating at the Quinault River Bridge in Taholah, located in the Quinault Indian Reservation. The Washington State Legislature extended the roadway north to end at US 101 south of Queets through tribal lands, although this segment has yet to be built. SR 109 was first established as Secondary State Highway 9C (SSH 9C) in 1937, which was on a more northern alignment until 1947, when it was switched to a Hoquiam to Quinault Indian Reservation route. In 1964, SSH 9C was renumbered to SR 109 and in 1983, a spur route of SR 109 that bypasses Hoquiam was added. SR 109 itself was extended by the legislature to US 101 near Queets in 1985, but the road has not been built.
