The state highway system of the U.S. state of California is a network of highways that are owned and maintained by the California Department of Transportation (Caltrans).
Route 710, consisting of the non-contiguous segments of State Route 710 (SR 710) and Interstate 710 (I-710), is a major north–south state highway and auxiliary Interstate Highway in the Los Angeles metropolitan area of the U.S. state of California. Also called the Los Angeles River Freeway prior to November 18, 1954, the highway was initially planned to connect Long Beach and Pasadena, but a gap in the route exists from Alhambra to Pasadena through South Pasadena due to community opposition to its construction.
The Santa Ana Freeway is one of the principal freeways in Southern California, connecting Los Angeles and its southeastern suburbs including the freeway's namesake, the city of Santa Ana. The freeway begins at its junction with the San Diego Freeway, called the El Toro Y, in Irvine, signed as I-5. From there, it generally goes southeast to northwest to the East Los Angeles Interchange, where it takes the designation of U.S. Route 101 (US 101). It then proceeds 2.95 miles (4.75 km) northwest to the Four Level Interchange in downtown Los Angeles. Formerly, the entirety of the route was marked as US 101 until the 1964 highway renumbering, which truncated US 101 to the East Los Angeles Interchange and designated the rest of the freeway as I-5.
State Route 13 is a state highway in the U.S. state of California. It runs entirely in Alameda County, connecting Interstate 580 in Oakland to Interstate 80/Interstate 580 in Berkeley.
State Route 82 is a state highway in the U.S. state of California that runs from Interstate 880 (I-880) in San Jose to I-280 in San Francisco following the San Francisco Peninsula. It is the spinal arterial road of the peninsula and runs parallel to the nearby Caltrain line along much of the route. For much of its length, the highway is named El Camino Real and formed part of the historic El Camino Real mission trail. It passes through and near the historic downtowns of many Peninsula cities, including Burlingame, San Mateo, Redwood City, Menlo Park, Palo Alto, Mountain View, Sunnyvale, and Santa Clara, and through some of the most walkable and transit-oriented neighborhoods in the region.

SR 39's northern terminus is at Islip Saddle on Angeles Crest Highway in the Angeles National Forest, but its northernmost 4.5-mile (7.2 km) segment has been closed to public highway traffic since 1978 due to a massive mud and rockslide.
State Route 61 is a state highway in the U.S. state of California, running along the eastern edge of Oakland International Airport and through Alameda. Two additional "hidden" state highways, State Route 112 and State Route 260, are also signed as part of SR 61, despite having legal descriptions separate from Route 61.

The combined route is a north–south four-to-six lane suburban roadway, lying east of the Long Beach Freeway and west of the San Gabriel River Freeway, and connecting the eastern parts of Long Beach and Pasadena via the Whittier Narrows. Under their legal descriptions, SR 19 runs north to Gallatin Road in Pico Rivera, then SR 164 goes from Gallatin Road to Pasadena. Since 1998, several pieces have been relinquished to local governments, and more transfers are authorized by state law.

It serves as a short freeway connection between the Interstate 80/Interstate 80 Business junction and Auburn Boulevard. SR 244 was first added to the state highway system in 1959 as Legislative Route 288, and was renumbered as SR 244 in the 1964 renumbering. Portions of this route have been removed from the system as recently as 1994.

State Route 213 is a state highway in the U.S. state of California, in Los Angeles County. The California State Legislature has designated the route as Western Avenue from 25th Street in San Pedro north to the San Diego Freeway in Torrance. From 25th Street to Carson Street, the California Transportation Commission has officially adopted Western Avenue as a state highway. The segment of Western Avenue from 25th Street south to Paseo del Mar may have SR 213 signage but is not legally part of the highway. The northerly two miles from Carson Street to Interstate 405 has also not yet been adopted and remains a city street. Beyond Interstate 405, Western Avenue, continues through Torrance, Gardena, and Los Angeles to Los Feliz Boulevard in Hollywood as a city street.
