SR 79, SR 371, and SR 74 form a heavily-used, scenic shortcut from Temecula in southwestern Riverside County to the Coachella Valley in central Riverside County. This provides a shorter corridor from San Diego to the Coachella Valley, avoiding the heavily congested freeway route via Interstate 15 to Murrieta, Interstate 215 to Riverside, SR 60 to Beaumont, and then Interstate 10.
SR 371 was part of SR 71 until 1973, when SR 79 and SR 71 were co-signed from Temecula to Aguanga to Temecula. In 1974, the portion of SR 71 from Temecula to Corona along I-15's current alignment was deleted, and the orphaned route from Aguanga to Anza was re-signed as SR 371.
