Route description

Fishlake Scenic Byway is a route of 29.6 mi (47.6 km) that traverses mainly through the Fishlake National Forest, Utah. The byway comprises SR-25 and County Roads FAS-2554 and FAS-3268, beginning at SR-24, and running to SR-72. The byway starts at an intersection with SR-24 and immediately turns north-northeast through mountainous terrain before descending into a basin where Fish Lake is located. The route continues northeast and passes the west shore of Fish Lake, Johnson Valley Reservoir, and ending at the junction of SR-72, just nine miles northeast of the township of Loa in southeast Utah.

History

The road from SR-24 at Plateau Junction east to Fish Lake was added to the state highway system in 1918,^[2] and numbered SR-25 by the state legislature in 1927.^[3] The west end was moved south to Fish Lake Junction in 1935 as a federal aid project,^[2] but the legislative description was not changed until 1953.^[4] The Fishlake Scenic Byway was designated on April 9, 1990 on SR-25 between SR-24 and Johnson Valley Reservoir. The Byway was extended in August 1992 between Johnson Valley Reservoir and SR-72 to comprise the southern portion of the Gooseberry/Fremont Road Scenic Backway.
