County Road S1
Location	San Diego County
Tourist routes	Sunrise Scenic Byway

County Route S1 (CR S1), also known as Sunrise Highway for a portion of its length, is a 34.08 mi (54.85 km) long county highway located entirely in San Diego County, California, United States. It begins at State Route 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.^[2][3]

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.^[4]

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.^[5] 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.^[3] Upon passing the settlement of Mount Laguna, the vegetation along the route mostly consists of dead trees devastated by the 2003 Cedar Fire.

As the route approaches its north end at State Route 79, Lake Cuyamaca is visible. The north terminus is located just north of Cuyamaca Rancho State Park where it meets SR 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.^[6] The northern segment of the route was also established as a Scenic Byway in 1959.^[7]

County Route S2 (CR S2) is a county highway in the U.S. state of California. It runs for 65 miles (105 km), north–south, in Imperial County and San Diego County. CR S2 is the third longest county route in California and is almost exclusively a two-lane rural road. It largely follows the route of the former Southern Emigrant Trail and Butterfield Overland Mail.

Route description

Starting at mile marker zero, the highway begins at a junction with State Route 79 near the community of Warner Springs. As it descends southeast toward the desert floor it becomes San Felipe Road until it crosses State Route 78 at Scissors Crossing in Shelter Valley (formerly called Earthquake Valley).^[8] South of SR 78, the name of the highway changes to the Great Southern Overland Stage Route of 1849, then further south, it forks at a remote junction with the historic dirt road to become to Sweeney Pass Road. East of the San Diego/Imperial County Line of this segment is also called Imperial Highway. The highway runs south through an interchange with Interstate 8 then ends at a junction with State Route 98 near Ocotillo.

Location	San Diego County

This section needs expansion. You can help by adding to it. (February 2010)

County Route S7 (CR S7) is a county highway in San Diego County, California, United States, that provides access to Palomar Mountain.

Route description

CR S7's western terminus is at State Route 76 east of Pauma Valley, California. It begins as a dirt road known as the Nate Harrison Grade. Then it returns to pavement as it ascends Palomar Mountain and meets San Diego County Route S6. It enters Palomar Mountain State Park. Then, it descends to end at SR 76 near Lake Henshaw.

Nate Harrison Grade is not signed as County Route S7, but it is a logical westward extension of the signed portion. With a 10% grade, it was the only road to the top of Palomar Mountain until the 1940s, when East Grade Road ("Highway to the Stars") was built for the construction of the Palomar Observatory. The road was formerly known as "Nigger Nate Road", named after Nate Harrison, an early African-American homesteader. The name was changed in 1956 at the request of the NAACP.^{[9][10][11][12][13][14]}

On a small turnout is a monument to Gregory Pacheco and a good view to the north. According to a plaque at the monument, pictured below, Gregory Pacheco was a firefighter who died in the La Jolla Fire in 1999. The descent on the eastern side of Palomar Mountain offers panoramic views of Lake Henshaw.

Route description

CR S10 begins at Encinitas Boulevard in Encinitas, heading in a generally northward direction. It enters Carlsbad and turns eastward. This road travels into San Marcos and passes near the unincorporated area of Lake San Marcos.

County Route S12 (CR S12), also known as Palomar Airport Road, San Marcos Boulevard, Twin Oaks Valley Road, and Deer Springs Road, is a county highway in San Diego County, California, United States. It runs through the North County region of San Diego County from Carlsbad Boulevard (County Route S21) in Carlsbad to Interstate 15 near Hidden Meadows.

Route description

CR S12's western terminus is at Carlsbad Boulevard (CR S21) in Carlsbad. Almost immediately after it begins, CR S12 (this portion of which is called Palomar Airport Road) intersects with Interstate 5. It passes Legoland California and continues eastward, passing its namesake, McClellan–Palomar Airport. It intersects with El Camino Real (CR S11) before running through a number of industrial and business parks. Eventually, CR S12 enters San Marcos, where it becomes San Marcos Boulevard after an intersection with Business Park Drive. San Marcos Boulevard intersects Rancho Santa Fe Road (CR S10) and continues eastward, crossing State Route 78. Shortly thereafter, San Marcos Boulevard intersects with Twin Oaks Valley Road, which assumes the S12 designation after this junction. Shortly after becoming CR S12, Twin Oaks Valley Road passes over Mission Road (CR S14) without actually intersecting it, then continues to the northern city limits of San Marcos. At the edge of the city, Twin Oaks Valley Road narrows into a private road, and CR S12 bears right to become Deer Springs Road, which continues northward through unincorporated land. Eventually the road turns east, and CR S12 ends at an interchange with Interstate 15, though the road itself continues as Mountain Meadow Road through Hidden Meadows.

The route was established in 1961.

S13

County Road S13
Location	San Diego County

This section needs expansion. You can help by adding to it. (February 2010)

County Route S13 (CR S13), also known as Vista Village Drive, East Vista Way, and Mission Road, is a county highway in San Diego County, California, United States, that runs through the North County region of San Diego County. It is distinctive for having a three-mile (5 km) discontinuity in Bonsall.

Route description

CR S13's southern terminus is at State Route 78 in Vista, where the street is known as Vista Village Drive. This section of CR S13 is the northern boundary of the newly renovated downtown area of Vista, and in this area the road intersects with Santa Fe Avenue, which is CR S14. Shortly afterwards, the road's name changes to East Vista Way, and continues northward outside the city limits into the unincorporated community of Bonsall.

CR S13 is unusual in that, according to official legislation, its route is discontinuous. In Bonsall, East Vista Way meets State Route 76 and, from this point, loses its status as CR S13. Nearly three miles northeast on SR 76, CR S13 begins again, continuing northward, but as South Mission Road.

Mission Road cuts north through Bonsall and passes the neighborhoods of San Luis Rey Heights and Winterwarm before entering Fallbrook. In Fallbrook, South Mission Road splits off into South Main Avenue, which carries the S13 signage. These two streets run parallel to each other for several blocks; East Fallbrook Road (SR S15) begins at Mission and intersects Main. After a short distance, Mission turns east, intersecting Main; Mission then continues as S13. CR S13 continues eastward, ending at an interchange with Interstate 15.

Almost all of S13, except for later realigned portions, is an old alignment of U.S. Route 395, and Historic Route signs are posted in unincorporated areas.

The route was established in 1968.
