context_page_description: There are 34 routes assigned to the "S" zone of the California Route Marker Program, which designates county routes in California. The "S" zone includes county highways in Imperial, Orange, Riverside, San Diego, and Santa Barbara counties.
context_section_description: County Route S6 is a county route in San Diego County, California. It connects Del Mar with Palomar Mountain across San Diego County. It is one of a few San Diego County Routes with a discontinuity in its routing.
  S6 starts at San Diego County Route S21 in Del Mar as Via de la Valle.  It crosses Interstate 5 and meets with S8 in Rancho Santa Fe at the intersection of Via de la Valle and Paseo Delicias.  At El Camino Del Norte the name changes to Del Dios Highway, past the community of Del Dios and into Escondido, California.
  In Escondido, S6 runs along West and East Valley Parkways, to Valley Center Road through Valley Center, California. S6 ends at State Route 76.
  About four miles (6.4 km) east on SR 76, S6 begins again as South Grade Road, which winds northward on Palomar Mountain. It intersects with S7, then continues north until it ends at the Palomar Observatory.
  The route was defined in 1959.
