the official state highway map. The route number conversion was completed by 1982—by that time, the entire highway was completely paved. At the request of White Pine County's Board of Tourism and Recreation, the Nevada Board of Transportation renamed SR 318 from "Sunnyside Road" to the "Silver State Classic Challenge Highway" on May 24, 2012. More than 100 miles of the highway, between Lund, Nevada and Hiko, Nevada are closed twice a year for the Nevada Open Road Challenge and Silver State Classic Challenge road races. On June 24, 2020, part of the highway was closed near Lund, Nevada as the Brown Fire grew, burning almost parallel to the highway. Major intersections Note: Mileposts in Nevada reset at county lines; the start and end mileposts for each county are given in the county column.
