19 of the Oregon state highway system,[2] named after John C. Frémont.

The northern terminus of the highway is at an intersection with U.S. Route 97 south of the city of La Pine.

The road then runs east near the south shore of Summer Lake, then southeast through Paisley.

A previous routing from a 1916 map shows the highway's northern terminus near Millican on U.S. 20, proceeding down Forest Road 25, then down Forest Road 18/Cabin Lake Road to the community of Fort Rock and continuing south on Pitcher Lane and Picture Lane to Silver Lake.
