SR-46 begins at La Sal Junction, a T intersection with US 191 about 22 miles (35 km) south of Moab in northeastern San Juan County, Utah.

From its western terminus SR-46 heads easterly for about 2.2 miles (3.5 km) before entering the census-designated place (CDP) of La Sal.

Just before leaving the National Forest, SR-46 enters the unincorporated community of Old La Sal.

(The roadway continues east as Colorado State Highway 90 toward Bedrock and Naturita.)
