State Route 99 (SR 99) is a major north–south state highway in the U.S. state of California, stretching almost the entire length of the Central Valley. From its southern end at Interstate 5 (I-5) near Wheeler Ridge to its northern end at SR 36 near Red Bluff, SR 99 goes through the densely populated eastern parts of the valley.

State Route 120 is a state highway in the central part of California, connecting the San Joaquin Valley with the Sierra Nevada, Yosemite National Park, and the Mono Lake area. Its western terminus is at Interstate 5 in Lathrop, and its eastern terminus is at U.S. Route 6 in Benton. While the route is signed as a contiguous route through Yosemite, the portion inside the park is federally maintained and is not included in the state route logs. The portion at Tioga Pass at Yosemite's eastern boundary is the highest paved through road in the California State Route system. This part is not maintained in the winter and is usually closed during the winter season.
The State Scenic Highway System in the U.S. state of California is a list of highways, mainly state highways, that have been designated by the California Department of Transportation (Caltrans) as scenic highways. They are marked by the state flower, a California poppy, inside either a rectangle for state-maintained highways or a pentagon for county highways.

State Route 35, generally known as Skyline Boulevard for most of its length, is a mostly two-lane state highway in the U.S. state of California. It runs along the ridge of the Santa Cruz Mountains from the high point of State Route 17 near Lexington Reservoir in Santa Clara County to State Route 1 just south of Daly City in San Mateo County, where it crosses SR 1 and loops around Lake Merced to become Sloat Boulevard in San Francisco. SR 35 then continues along Sloat Boulevard until it reaches its terminus when it meets SR 1 again at 19th Avenue.

State Route 49 is a north–south state highway in the U.S. state of California that passes through many historic mining communities of the 1849 California gold rush and it is known as the Golden Chain Highway. The road was initially lobbied in 1919 by the Mother Lode Highway Association, a group of locals and historians. The highway begins at State Route 41 in Oakhurst, Madera County, in the Sierra Nevada. It continues in a generally northwest direction, weaving through the communities of Goldside and Ahwahnee, before crossing into Mariposa County.

Its southern terminus is at the Cabrillo Highway in Morro Bay, and its northern terminus is at SR 140 in Yosemite National Park.

State Route 33 is a north–south state highway in the U.S. state of California. It runs north from U.S. Route 101 in Ventura through the Transverse Ranges and the western side of the San Joaquin Valley to Interstate 5 at a point east of Tracy. SR 33 replaced part of U.S. Route 399 in 1964 during the "great renumbering" of routes. In the unincorporated sections of Kern County it is known as the West Side Highway. In addition, the California Legislature designated the entire Kern County portion as the Petroleum Highway in 2004. The southernmost portion in Ventura is a freeway known as the Ojai Freeway, while it is known as the Maricopa Highway from Ojai to Maricopa.

State Route 132 is a state highway in the U.S. state of California that connects the Central Valley with the Sierra Nevada foothills and the California Gold Country. Its western segment also connects the city of Modesto with the San Francisco Bay Area via I-580, although this route is discouraged due to it being a two-lane road between Modesto and Interstate 5. East of Modesto, the road climbs the foothills and eventually ends at SR 49 at Coulterville.

It generally runs northeast from downtown Modesto near the SR 99/SR 132 interchange, to U.S. Route 395 near the Nevada state line. The route was once recommended to continue south of Modesto to Interstate 5, although today that portion exists as a county road. Parts of SR 108 are closed annually during the winter due to inclement weather along the summit.
State Route 127 is a state highway in the U.S. state of California that connects Interstate 15 in Baker to Nevada State Route 373 at the Nevada state line, passing near the eastern boundary of Death Valley National Park. The entire length of the highway closely follows the central portion of the former Tonopah and Tidewater Railroad and loosely follows the Amargosa River.

The gap in between segments is connected by various local roads and State Route 190 through Death Valley National Park. The western segment runs from State Route 99 in Bakersfield and over the Walker Pass in the Sierra Nevada to the turnoff for the Trona Pinnacles National Natural Landmark. The eastern segment runs from the southeasterly part of Death Valley to Nevada State Route 372 at the Nevada state line.
The Ferguson landslide, also commonly called the Ferguson Slide, is an active landslide in the Merced River canyon in Mariposa County, California, United States. In 2006, rocks and debris slid off Ferguson Ridge, blocking California State Route 140, a primary access road to Yosemite National Park. The slide still blocked the original road as of June 2024, although temporary bridges allow one-way traffic around the slide and into the park. The slide is a natural phenomenon, and resulted from the erosion dynamics of the river valley.
