It connects U.S. Route 101 (US 101) at Sappho to SR 112 near Clallam Bay, traveling north along Beaver Creek and the Pysht River for 10 miles (16 km).

It was part of Secondary State Highway 9A (SSH 9A), which connected Sappho to Port Angeles along the Strait of Juan de Fuca.

The north–south section of SSH 9A was removed from the state highway system in 1955 and was transferred back to Clallam County and renamed Burnt Mountain Road.

The county road gained Forest Highway status in 1961 and was rebuilt and paved with federal and state funds over the following decade.

[5] The corridor is also served by a Clallam Transit bus route that connects Forks to Neah Bay, with intermediate stops at both termini of SR 113.

[18] Construction of the road's new alignment began in 1962 near Sappho after the county agreed to contribute $220,000 (equivalent to $1.54 million in 2023 dollars)[17] to the project.
