State Route 79 (SR 79) is an approximately 91-mile (146 km) north-south state highway in the U.S. state of California. The highway's southern terminus is at Interstate 8 (I-8) at the Descanso Junction in San Diego County. Its northern terminus is at Interstate 10 (I-10) in the city of Beaumont in Riverside County. In San Diego County, SR 79 connects with Lake Cuyamaca and Cuyamaca Rancho State Park, the communities of Julian and Warner Springs. In Riverside County, the highway runs through the cities of Temecula, Murrieta, Hemet, and San Jacinto before reaching Beaumont. Though some maps and signs may still mark SR 79 as continuous through the cities of Temecula and San Jacinto, control of segments within those cities were relinquished to those local jurisdictions and are thus no longer officially part of the state highway system.
