The Humboldt Wagon Road, or the Humboldt Road, was a freight wagon road in northern California. Constructed in the 1860s, it connected Chico, near the Sacramento River, with Susanville, near Honey Lake, east of the Sierra Nevada crest. From there, extensions continued to the Humboldt silver mines in Nevada and the Owyhee Mines near Silver City, Idaho.[1] The road was surveyed and financed by prominent settler John Bidwell and carried passengers, mail, and freight between logging and ranching communities of northeastern California. It also contributed to the settlement of the region and the displacement of the native Maidu population. Portions of the Humboldt Road are now followed by California State Route 32 and California State Route 36.
