State Route 78 (SR 78) is a state highway in the U.S. state of California that runs from Oceanside east to Blythe, traversing nearly the entire width of the state. Its western terminus is at Interstate 5 (I-5) in San Diego County and its eastern terminus is at I-10 in Riverside County. The route is a freeway through the heavily populated cities of northern San Diego County and a two-lane highway running through the Santa Rosa Mountains to Julian. In Imperial County SR 78 travels through the desert near the Salton Sea and passes through the city of Brawley before turning north and passing through an area of sand dunes on the way to its terminus in Blythe. SR 78 was one of the original state highways designated in 1934, although portions of the route existed as early as 1900. However, it was not designated east of Brawley until 1959. The freeway section in the North County of San Diego that connects Oceanside and Escondido was built in the middle of the twentieth century in several stages, including a transitory stage known as the Vista Way Freeway, and has been improved several times. There are many projects slated to improve the freeway due to increasing congestion in that region. An expressway bypass of the city of Brawley is also under construction.

The Ridge Route, officially the Castaic-Tejon Route, was a two-lane highway running between Los Angeles and Kern counties in California. Opened in 1915 and paved with concrete between 1917 and 1921, the road was the first paved highway directly linking the Los Angeles Basin with the San Joaquin Valley over the Tejon Pass and the rugged Sierra Pelona Mountains ridge south of Gorman. Most of the road was bypassed in 1933 by the Ridge Route Alternate (then U.S. Route 99), which has since been upgraded to a modern freeway, Interstate 5. The portion of the road within the Angeles National Forest was added to the National Register of Historic Places in 1997 and is closed pending repairs; other remnants of the road still remaining are used by local traffic.

U.S. Route 199 (US 199) is a U.S. highway in the U.S. states of California and Oregon. The highway was established in 1926 as a spur of U.S. Route 99, which has since been replaced by Interstate 5 (I-5). US 199 stretches 80 miles (130 km) from US 101 near Crescent City, California, northeast to I-5 in Grants Pass, Oregon. The highway is the northern portion of the Redwood Highway. In Oregon, US 199 is officially known as Redwood Highway No. 25. The majority of the road in California is the Smith River Scenic Byway, a Forest Service Byway. This route is part of the California Freeway and Expressway System and is eligible for the State Scenic Highway System. The first roadway, a plank road, from Crescent City was established in May 1858, and before the US 199 designation was applied to the highway, the roadway was designated Highway 25 and Route 1.

The Arroyo Seco Parkway, formerly known as the Pasadena Freeway, is the first freeway in California and the western United States. It connects Los Angeles with Pasadena alongside the Arroyo Seco. It is notable not only for being the first, mostly opened in 1940, but for representing the transitional phase between early parkways and modern freeways. It conformed to modern standards when it was built, but is now regarded as a narrow, outdated roadway. A 1953 extension brought the south end to the Four Level Interchange in downtown Los Angeles and a connection with the rest of the freeway system. The road remains largely as it was on opening day, though the plants in its median have given way to a steel guard rail, and it now carries the designation State Route 110, not historic U.S. Route 66. Between 1954 and 2010, it was officially designated the Pasadena Freeway. In 2010, as part of plans to revitalize its scenic value and improve safety, Caltrans renamed the roadway back to its original name. All the bridges built during parkway construction remain, as do four older bridges that crossed the Arroyo Seco before the 1930s. The Arroyo Seco Parkway is designated a State Scenic Highway, National Civil Engineering Landmark, and National Scenic Byway. It was listed in the National Register of Historic Places in 2011.

State Route 57 (SR 57), also known as the Orange Freeway, is a north–south state highway in the Greater Los Angeles Area of the U.S. state of California. It connects the interchange of Interstate 5 (I-5) and SR 22 near downtown Orange, locally known as the Orange Crush, with the Glendora Curve interchange with I-210 and SR 210 in Glendora. The highway provides a route across several spurs of the Peninsular Ranges, linking the Los Angeles Basin with the Pomona Valley and San Gabriel Valley. A predecessor to this road ran through Brea Canyon by the early 20th century, and was added to the state highway system. The freeway was built in stages during the 1950s, one of which included the Brea Canyon Freeway; SR 57 was subsequently designated as part of the 1964 state highway renumbering. The final portion of the Orange Freeway that has been completed to date was not built until the early 1970s. The latest piece of SR 57 to be added was formerly part of I-210, after SR 210 was extended to San Bernardino in 1998. An unconstructed extension from Santa Ana south to Huntington Beach remains in the legal definition of Route 57, and has been studied most recently as a toll road above the Santa Ana River.

State Route 37 (SR 37) is a state highway in the northern part of California that runs 21 miles (34 km) along the northern shore of San Pablo Bay. It is built from U.S. Route 101 in Novato and runs through the southern tips of Sonoma and Napa counties to Interstate 80 in Vallejo. It serves as a vital connection between the four counties of the North Bay Area, north of San Francisco. SR 37 has been proposed to be built to freeway standards since the early 1950s. However, the proposal was met with many economic and environmental obstacles, making the task all but impossible for much of the route. Notable problems included a levee break in Vallejo which turned part of the land around the highway into a marsh that is home to endangered species, and a section of highway known as "Blood Alley" for its high rate of fatal accidents.

State Route 52 (SR 52) is a state highway in the US state of California in San Diego County, that extends from La Jolla Parkway at Interstate 5 (I-5) in La Jolla to SR 67 in Santee. It is a freeway for its entire length, and serves as a major east–west route through the northern part of the city of San Diego. The road connects the major north–south freeways of the county, including I-5, I-805, SR 163, I-15, SR 125, and SR 67. SR 52 passes north of the Rose Canyon Fault before traversing Marine Corps Air Station Miramar. East of Santo Road and west of SR 125, the highway goes through Mission Trails Regional Park, a large open space. SR 52 is also known as the Soledad Freeway and the San Clemente Canyon Freeway. Plans for a route between La Jolla and Santee date back from 1959. Construction began in 1966 with the I-5 interchange to La Jolla, and the San Clemente Canyon Road serving as an early predecessor. The freeway was complete all the way to I-805 in 1970, and to Santo Road east of I-15 in 1988. However, the road east of there faced delays from environmentalists over the endangered Least Bell's Vireo songbird, which faced habitat destruction, as well as those concerned with the destruction of homes and businesses for the right of way for the freeway. The extension to Mission Gorge Road opened in 1993, and opened all the way to SR 125 in 1998. Funding issues delayed the completion of the entire route to SR 67 until 2011, over fifty years after construction began; until then, the city of Santee faced traffic snarls. A widening project was completed in 2007 between Santo Road and Mast Boulevard; further widening has been put on hold due to state budget concerns.

State Route 56 (SR 56) is an east–west state highway in the U.S. state of California. It runs 9.210 miles (14.822 km) from Interstate 5 (I-5) in the Carmel Valley neighborhood of San Diego to I-15. The eastern terminus of the highway is also the western end of the Ted Williams Parkway. SR 56 serves as an important connector between I-5 and I-15, being the only east–west freeway between SR 78 in north San Diego County, several miles away, and SR 52 near Marine Corps Air Station Miramar. It is also named the Ted Williams Freeway, after the San Diego-born baseball player. SR 56 was added to the state highway system in 1959 as Legislative Route 278, and was renumbered SR 56 in the 1964 state highway renumbering. Plans in 1964 were to connect SR 56 to the north end of SR 125 and continue east to SR 67, but these plans did not come to fruition. The eastern end from Black Mountain Road to I-15 was completed in 1993; the western end from I-5 to Carmel Creek Road was completed in 1995 after several lawsuits filed by the Sierra Club and other community groups. The two ends were not connected until the middle portion of the freeway was completed in 2004. The delay was largely due to funding issues and environmental concerns.

State Route 67 (SR 67) is a state highway in San Diego County, California. It begins at Interstate 8 (I-8) in El Cajon and continues to Lakeside as the San Vicente Freeway before becoming an undivided highway through the eastern part of Poway. In the town of Ramona, the route turns into Main Street before ending at SR 78. SR 67 provides direct access from the city of San Diego to the East County region of San Diego County, including Ramona and Julian. The route has existed as a railroad corridor since the turn of the 20th century. A highway known as the Julian road was built by 1913, and was designated as Legislative Route 198 in the state highway system by 1935. Route 198 was renumbered SR 67 in the 1964 state highway renumbering. A freeway south of Lakeside was built in the late 1960s, and opened to traffic in 1970. Since then, the portion of the highway north of Lakeside has become known for a high number of traffic accidents and related fatalities. The California Department of Transportation (Caltrans) has made several attempts to remedy the problem and make the road safer.

State Route 75 (SR 75) is a short, 13-mile (21 km) expressway in San Diego County, California. It is a loop route of Interstate 5 (I-5) that begins near Imperial Beach, heading west on Palm Avenue. The route continues north along the Silver Strand, a thin strip of land, through Silver Strand State Beach. SR 75 passes through the city of Coronado as Orange Avenue and continues onto the San Diego–Coronado Bay Bridge, which traverses the San Diego Bay, before joining back with I-5 near downtown San Diego at a freeway interchange. Orange Avenue dates from the late 19th century, and the Silver Strand Highway was constructed and open to the public by 1924. What would become SR 75 was added to the state highway system in 1933, and designated Legislative Route 199 in 1935. SR 75 was not officially designated until the 1964 state highway renumbering. The Coronado Bay Bridge opened in 1969, and provided a direct connection between San Diego and Coronado. Since then, various proposals have taken place to relieve commuter traffic between San Diego and North Island Naval Air Station that traverses the city of Coronado. However, none of these proposals have gained support, including an attempt in 2010.

Interstate 805 (I-805) is a major north–south Interstate Highway in Southern California. It is a bypass of I-5, running along the eastern areas of the Greater San Diego region from San Ysidro (part of the city of San Diego) near the Mexico–U.S. border to near Del Mar. The southern terminus of I-805 at I-5 in San Ysidro is less than a mile north of the Mexican border. I-805 then traverses through the cities of Chula Vista and National City before reentering San Diego. The freeway passes though the San Diego neighborhoods of North Park, Mission Valley, Clairemont, and University City before terminating at I-5 in the Sorrento Valley neighborhood near the Del Mar city limit. Planning for I-805 began in 1956, and the route was officially designated in 1959 before it was renumbered in the 1964 state highway renumbering. Starting in 1967, the freeway was built in phases, with the northern part of the freeway finished before the southern part. I-805 was completed and open to traffic in 1975. Named the Jacob Dekema Freeway after the longtime head of the regional division of the California Department of Transportation (Caltrans), I-805 has been frequently cited for its complex engineering and architecture, including near I-8 on the Mission Valley Viaduct. Since then, several construction projects have taken place, including the construction of local and express lanes at the northern interchange with I-5. High-occupancy toll lanes are under construction on both the northern and southern portions of the route.

State Route 94 (SR 94) is a highway in the U.S. state of California. The western portion is known as the Martin Luther King Jr. Freeway that begins at Interstate 5 (I-5) in downtown San Diego and continues to the end of the freeway portion past SR 125 in Spring Valley. The non-freeway segment of SR 94 that continues east to I-8 near Boulevard is known as Campo Road. The Campo road served as a wagon road providing access to eastern San Diego County as well as Imperial County. The road was added to the state highway system in 1933, and signs for Route 94 were posted along local roads later that decade. Efforts to convert the western half of the route to a freeway took place in the 1950s, and the freeway was complete by 1962 west of the road that became SR 125. Construction continued east to Avocado Road over the next few years. Various proposals for widening the highway have come from Caltrans, but local opposition resulted in the delay or cancellation of many of these proposals.

Interstate 8 (I-8) is an Interstate Highway in the southwestern United States. It runs from the southern edge of Mission Bay at Sunset Cliffs Boulevard, in San Diego, California, almost at the Pacific Ocean, to the junction with I-10, just southeast of Casa Grande, Arizona. In California, the freeway travels through the San Diego metropolitan area before traversing the Cuyamaca Mountains and providing access through the Imperial Valley, including the city of El Centro. Crossing the Colorado River into Arizona, I-8 continues through the city of Yuma across the Sonoran Desert to Casa Grande, in between the cities of Phoenix and Tucson. The first route over the Cuyamaca Mountains was dedicated in 1912, and a plank road served as the first road across the Imperial Valley to Yuma. These were later replaced by U.S. Route 80 (US 80) across California and part of Arizona. The US 80 freeway through San Diego was largely complete by the time it was renumbered as I-8 in the 1964 state highway renumbering; east of San Diego, the US 80 roadway was slowly replaced by I-8 as construction progressed in the Imperial Valley. The route was completed in 1975 through California, though the bridge over the Colorado River was not completed until 1978.

State Route 282 (SR 282) is an east–west state highway entirely within the city of Coronado, California. It is a spur of SR 75 and connects the rest of the state highway system with Naval Air Station North Island. The road is part of a link connecting to the metropolitan area of San Diego via SR 75 and the Coronado Bay Bridge. The entire route uses a one-way couplet, with Third Street in the westbound direction and Fourth Street in the eastbound direction. Third and Fourth streets, as part of the Coronado street system, have existed since the 19th century, and were paved in the early 20th century. SR 282 was designated in 1968, around the time the San Diego–Coronado Bridge was opened. Attempts to build first a highway, and later a tunnel, to allow base traffic to bypass the Coronado city streets, were rejected by voters in 1974 and 2010, respectively.

State Route 76 (SR 76) is a 52.63-mile-long (84.70 km) state highway in the U.S. state of California. It is a frequently used east–west route in the North County region of San Diego County that begins in Oceanside near Interstate 5 (I-5) and continues east. The highway serves as a major route through the region, continuing east into the community of Bonsall while providing access to Fallbrook. East of the junction with I-15, SR 76 goes through Pala and Pauma Valley before terminating at SR 79. A route along the corridor has existed since the early 20th century, as has the bridge over the San Luis Rey River near Bonsall. The route was added to the state highway system in 1933, and was officially designated as SR 76 in the 1964 state highway renumbering, though the route was known as SR 76 before then. The section of the highway through Oceanside and Bonsall is mostly a four-lane expressway; east of Bonsall, SR 76 is mostly a two-lane highway. Originally, the entire highway was two lanes wide; west of Bonsall, the route was widened in stages, after decades of funding shortages, planning, and litigation. Caltrans plans to expand the entire length of the highway west of I-15 to an expressway.

State Route 54 (SR 54) is a state highway in San Diego, California that connects Interstate 5 (I-5) in Chula Vista and National City to the city of El Cajon. The westernmost part of the highway is a freeway, intersecting with I-5, I-805, and SR 125; the part of the highway east of SR 125 is undivided, and portions are maintained by the county. The first section of the freeway opened in 1963, east of I-805. The extension of the freeway west to I-5 was delayed because a flood channel for the Sweetwater River was built with the extension. While construction started in 1984, a court stopped the process for a few years, and this portion was not complete until 1992. The final section of freeway, which was upgraded from an expressway, opened in 2007, to coincide with the extension of SR 125 south to Otay Mesa.

State Route 905 (SR 905) is a state highway in San Diego, California, that connects Interstate 5 (I-5) and Interstate 805 in San Ysidro to the United States – Mexico border at Otay Mesa. The entire highway from I-5 to the international border is a freeway with a few exits that continues east from the I-805 interchange before turning southeast and reaching the border. SR 905 was formerly routed on Otay Mesa Road, which had been in existence since at least 1927. Before it was SR 905, the route was first designated as part of SR 75, before it was redesignated as SR 117. The freeway was completed between I-5 and Otay Mesa Road in 1976. The border crossing opened in 1985, after several delays in obtaining funding for the construction of what would become SR 905. After becoming SR 905 in 1986, the highway was converted to first an expressway in 2000, and a freeway in 2010 and 2011. Plans are for this highway to eventually become known as Interstate 905.

U.S. Route 80 (US 80) was a U.S. highway in California that continued east across the country to Georgia. The western terminus was in San Diego, California, and US 80 continued east through the city on several different alignments through the years. The highway went through the Cuyamaca Mountains, encountering many switchbacks, before descending to El Centro. After passing through the sand dunes, the highway crossed the Colorado River into Yuma, Arizona. The highway replaced a 1912 plank road across much of Imperial County. The winding two-lane road through the Cuyamaca Mountains was one of the factors that led to a four-hour journey from San Diego to El Centro. During the 1930s, the road was realigned through the mountains, but several curves remained. In the 1950s, work began on constructing what would become Interstate 8 (I-8) to replace the old highway in San Diego to bypass the cities of San Diego, La Mesa, and El Cajon. The construction continued across the rest of the route through the next two decades. US 80 was gradually decommissioned after 1964 as I-8, through San Diego and Imperial counties, was completed. In 2006, the highway was designated by the California State Legislature as Historic U.S. Route 80.

In the U.S. state of California, U.S. Route 50 (US 50) runs east from I-80 in West Sacramento to the Nevada state line in South Lake Tahoe. Portions within Sacramento are known as the Capital City Freeway and El Dorado Freeway. The western half of the highway in California, from I-80 through Sacramento and Placerville to Exit 60 in Pollock Pines is a four-or-more-lane divided highway, mostly built to freeway standards. US 50 continues as an undivided highway with one eastbound lane and two westbound lanes until it reaches the canyon of the South Fork American River at Riverton. The remainder of the highway, which climbs along and out of the canyon, then over the Sierra Nevada at Echo Summit and into the Lake Tahoe Basin, is a mainly two-lane road. The US 50 corridor is a historic one, used by many 49ers who came to California during the Gold Rush as well as the Pony Express. In 1895, part of the present-day route was designated as California's first state highway, and it was later considered as a scenic alternate of the Lincoln Highway. Much of US 50 was constructed during the initial construction of the California state highway system. During the second half of the twentieth century, US 50 was gradually designated and converted into a modern highway.

Sierra Highway or El Camino Sierra is a road in Southern California, United States. El Camino Sierra refers to the full length of a trail formed in the 19th century, rebuilt as highways in the early 20th century, that ran from Los Angeles to Lake Tahoe following parts of modern State Route 14, U.S. Route 395 and State Route 89. Two portions of this road are currently signed as Sierra Highway. The first is an old alignment of SR 14/U.S. Route 6 from Los Angeles to Mojave. This road is also signed with the unusual designation of State Route 14U through the city of Santa Clarita. The second part signed as Sierra Highway is a portion of US 395 in Bishop. Traversing the extremes of California, from the Mojave Desert to the Sierra Nevada, El Camino Sierra has been advertised to the world as a highway to showcase the natural beauty of California as far back as 1910. Though most of Sierra Highway was bypassed in the early 1970s with freeways, the road is still well known. The portion through the San Gabriel Mountains is noted as the primary filming location for the film Duel.

State Route 198 (SR 198) is an east–west state highway that begins at U.S. Route 101 (US 101) south of King City and ends in Sequoia National Park. It connects the California Central Coast to the mid–Central Valley through Hanford and Visalia, although the most developed portion is in the Central Valley itself. SR 198 intersects the major north–south routes in the Central Valley, including Interstate 5 (I-5), SR 33, and SR 99. The highway that would become SR 198 was approved for construction in the 1910s through three bond issues, and was added to the state highway system in 1934. Parts of the highway were upgraded to freeway during the 1960s. Another portion is being converted to an expressway in between Hanford and Visalia, with completion scheduled for late 2012.

State Route 55 (SR 55) is an 18-mile (30-km) long north–south highway in the U.S. state of California. The portion of the route built to freeway standards is known as the Costa Mesa Freeway (formerly the Newport Freeway). SR 55 runs between Finley Avenue south of Pacific Coast Highway (SR 1) in Newport Beach and the Riverside Freeway (SR 91) in Anaheim to the north, intersecting other major Orange County freeways such as SR 22, SR 73, and Interstate 405 (I-405). The freeway passes through suburban Orange County. SR 55 was first added to the state highway system in 1931, known as part of Legislative Route 43, and was routed on surface streets. It was renumbered SR 55 in 1959, and the construction of the freeway portion began in the 1960s and continued until 1992. Due to congestion, several alternatives are being discussed to expand the freeway portion past its current end in Newport Beach. SR 55 received the first carpool lane in Orange County in 1985, and the first direct carpool ramp in 1995.

State Route 20 (SR 20) is a state highway in the northern central region of the U.S. state of California, running east–west across the state north of Sacramento. Its west end is at SR 1 in Fort Bragg, from where it heads east past Clear Lake, Colusa, Yuba City, Marysville, and Nevada City to I-80 near Emigrant Gap, where eastbound traffic can continue on other routes to Lake Tahoe or Nevada. Portions of SR 20 are built near the routing of what was first a wagon road and later a turnpike in the late nineteenth century. This road was extended through the state highway system all the way to Ukiah in the early twentieth century, and the missing link near Clear Lake was completed in 1932 before the official designation of this highway as SR 20 in 1934. There have been subsequent improvements to the road, such as the conversion of the Grass Valley portion of the route to freeway standards.

State Route 46 (SR 46) is an east–west state highway in the U.S. state of California. It is a major crossing of the Coast Ranges, connecting SR 1 on the Central Coast near Cambria and US 101 in Paso Robles with SR 99 at Famoso in the San Joaquin Valley. East of Paso Robles, where it carried U.S. Route 466 until 1964, SR 46 is part of the California Freeway and Expressway System, though it is mostly a two-lane highway. The highway from SR 1 to SR 41 near Cholame is an eligible State Scenic Highway, but has not been designated as such. The road that is now SR 46 was built and improved during the 1920s and was fully paved by 1930. The majority of SR 46 was originally designated as U.S. Route 466; however, after the latter was entirely removed from the U.S. Highway system, the eastern portion of the route became SR 46.

State Route 70 (SR 70) is a state highway in the U.S. state of California. Connecting Sacramento with U.S. Route 395 (US 395) near Beckwourth Pass (lowest in the Sierra Nevada) via the Feather River Canyon. Through the Feather River Canyon, from SR 149 to US 395, SR 70 is the Feather River Scenic Byway, a Forest Service Byway that parallels the ex-Western Pacific Railroad's Feather River Route. The Beckwourth Trail was the earliest predecessor of SR 70, which was a spur of the California Trail. This was followed by the railroad, mostly built on the route of the trail; a dirt road was needed for construction that was later converted into part of the present state highway. Construction on the highway began in 1928, which involved the boring of three tunnels. Previously, the road was signed as U.S. Route 40 Alternate, crossing the Sierra Nevada at a lower elevation than Donner Pass on US 40, now Interstate 80 (I-80). The road was renumbered SR 70 in the 1964 state highway renumbering. Today, portions of SR 70 have been upgraded to a four-lane expressway, and even a freeway in a few locations.
