Trona-Wildrose Road and Trona Road is a combined highway corridor which traverses some of the most remote regions of the Mojave Desert. Both roads are heavily tied to the founding of the community of Trona in 1913 but functionally existed all the way back to the plight of the Death Valley 49ers. The combined highway corridor is approximately 66.7 miles long from Panamint Valley Road in Inyo County and US Route 395 near Johannesburg of Kern County. Trona Road from Poison Canyon westward approximately 7.8 miles is carried as part of California State Route 178.
