The majority of the route is known as Fish Lake Valley Road, with the northern portion referred to as the Dicalite Cutoff.

From there, the highway follows Fish Lake Valley Road north to pass through the small community of Dyer.

As the route heads north from Dyer through Fish Lake Valley, Boundary Peak, the highest point in the state of Nevada, comes into view on the west side of the highway.

The route reaches its terminus at US 6, approximately 5 miles (8.0 km) east of Basalt.

[3] The route's northern terminus appears to have been shifted 8 miles (13 km) west of Coaldale around 1937.
