It was completed in 1913 under engineer A.D. Foote.","why_significant":"The road is significant as an engineering achievement, especially its dry-laid rock wall in Nevada County (Criterion C). It is also a notable work of mining engineer A.D. Foote (Criterion B). It served as a crucial transportation link to the Alleghany mines, and the form states it retains a high degree of integrity.","narrative":"Foote's Crossing Road is a 15.1-mile unpaved route linking the site of Columbia Hill in Nevada County with Alleghany in Sierra County. Completed in 1913, it drops into the Middle Fork of the Yuba River canyon at an even seven percent grade and climbs the far side, averaging about fifteen feet wide. Its most admired feature is roughly one mile of dry-laid stone wall that forms the bed and retaining wall along a steep cliff, built by skilled stone masons working from hanging stagings. Mining engineer A.D. Foote conceived the project to replace a nearly impassable route to the Alleghany mines, cutting a five-day supply trip to three days and allowing year-round travel. Funding came from both counties, the Forest Service and the Tightner Mine, and costs rose from an estimate of $7,000 to $85,000, much of it paid by Foote. The road remains in use and largely unchanged, which supports its recognition for engineering, its link to Foote and its role in mining transportation.","period_of_significance":"1913 (Completed)","architect_builder":"A.D.
