Henness Pass Road was the primary emigrant trail from Virginia City, Nevada as early as 1849 and the only mountain pass that existed at the time. During the Gold Rush, this often forgotten highway served as a supply road for the Comstock silver mines in Nevada. In 1852, Henness Pass Road was a wagon toll road from Nevada to the gold field of California. Between 1860 and 1868, traffic was so heavy at times during its heyday that freight wagons traveled by day and stagecoaches drove at night. The road continued to be used until the the completion of the transcontinental railway in 1868.
