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 S1, also known as Sunrise Highway for a portion of its length, is a 34.08 mi (54.85 km) long county route located entirely in San Diego County, California. It begins at SR 94 near Barrett and moves northward across Interstate 8, just west of the Laguna Summit. This segment is also known as Buckman Springs Road. North of I-8, it is the Sunrise Scenic Byway, a National Forest Scenic Byway.
  Route description
  The route begins at SR 94 near Barrett not far from the Mexican border. From there, it heads northward along Buckman Springs Road. Soon afterwards, it enters the Cleveland National Forest. When the road reaches Interstate 8, while Buckman Springs Road continues northeastward across the freeway, CR S1 continues in a northwest direction along Old Highway 80, the original alignment of U.S. Route 80 in California. It then closely parallels I-8 for several miles. Upon crossing the freeway at Laguna Junction, CR S1 separates from Old Highway 80 and becomes Sunrise Scenic Byway.
  From Interstate 8, it begins its ascent into the Laguna Mountains. The route here was built along a cliff overlooking Pine Valley to its west. Around here, the vegetation still consists of chaparral and sagebrush. As the route gains elevation through Cleveland National Forest, the route becomes more heavily forested. Around here, numerous campgrounds dot the side of the road. There is a picnic area overlooking Anza-Borrego Desert State Park near the Burnt Rancheria Campground, which is often said to deeply contrast the forest scenery along the route. Upon passing the settlement of Laguna Mountain, the vegetation along the route mostly consists of dead trees devastated by the 2003 Cedar Fire.
  As the route approaches its north end at SR 79, Lake Cuyamaca is visible. The north terminus is located just north of Cuyamaca Rancho State Park where it meets State Route 79.
  History
  The route was established by the county in the year 1959, where the entire route was designated as it is now. No major numbering or routing changes occurred throughout its history. The northern segment of the route was also established as a Scenic Byway in 1959.
