Piedra Road is an 8.6-mile highway corridor which runs mostly along the Kings River in Fresno County. The corridor as presently configured begins at Live Oak Avenue near California State Route 180 and terminates Trimmer Springs Road at the former quarry town of Piedra. Piedra Road was developed in 1911 as a frontage facility of the Wahtoke District Branch of the Atchison, Topeka & Santa Fe Railway. The railroad branch was withdrawn to Minkler in 1965 and Piedra Road would begin to become a major Fresno County highway connecting to numerous recreational locales.
