The route curves sharply east to climb up to Calavada Summit (elevation 6,254 feet [1,906 m]), and then turns northward again to pass over Petrified Summit (elevation 6,145 feet [1,873 m]) before leaving the mountain range.

[3] By 1939, the portion of the route in Mineral and Nye Counties had been realigned further east.

[4] The final alignment of SR 23, shown as a paved highway, was in place by 1946.

[5] The route remained relatively unchanged until the 1976 renumbering of Nevada's highway system.
