State Route 109 (SR 109) is a short, unsigned state highway in the U.S. state of California. It forms part of University Avenue in San Mateo County between U.S. Route 101 in East Palo Alto and State Route 84 in Menlo Park just west of the Dumbarton Bridge. Although the route is unsigned, it may be noted on some online maps.
SR 109 begins at U.S. Route 101 in East Palo Alto. It continues north, paralleling the city border with Menlo Park before entering Menlo Park and crossing a railroad. SR 109 passes by salt evaporators before terminating at SR 84 just west of the Dumbarton Bridge. [1]
In April 1958, I-109 was proposed as a name for the route that is now Interstate 280. This proposal was rejected by AASHTO. [2] The California State Route 109 designation was first defined in 1963, running from Sunset Cliffs Boulevard to Interstate 5 in San Diego. In 1972, that route was deleted and was renumbered as a western extension of Interstate 8. Later in 1984, SR 109 was defined as a route in Palo Alto.
The segment in East Palo Alto between US 101 and Notre Dame Avenue remains in local control. Under Cal S&HC § 409 (b), the state will not take control over this section until Caltrans and the city determine that it is in an "acceptable state of repair".
Except where prefixed with a letter, postmiles were measured on the road as it was when the route was established, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary ( ). [2] Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in San Mateo County.

The Bayshore Freeway is a part of U.S. Route 101 in the San Francisco Bay Area of the U.S. state of California. It runs along the west shore of the San Francisco Bay, connecting San Jose with San Francisco. Within the city of San Francisco, the freeway is also known as James Lick Freeway, named after the California philanthropist. The road was originally built as a surface road, the Bayshore Highway, and later upgraded to freeway standards. Before 1964, it was mostly marked as U.S. Route 101 Bypass, with US 101 using the present State Route 82.
State Route 58 is a major east-west state highway in the U.S. state of California that runs across the Coast Ranges, the southern San Joaquin Valley, the Tehachapi Mountains, which border the southern Sierra Nevada, and the Mojave Desert. It runs between U.S. Route 101 near Santa Margarita and Interstate 15 in Barstow. It has junctions with Interstate 5 near Buttonwillow, State Route 99 in Bakersfield, State Route 202 in Tehachapi, State Route 14 near Mojave, and U.S. Route 395 at Kramer Junction. SR 58 also provides access to Edwards Air Force Base.

State Route 92 is a state highway in the U.S. state of California, serving as a major east-west corridor in the San Francisco Bay Area. From its west end at State Route 1 in Half Moon Bay near the coast, it heads east across the San Francisco Peninsula and the San Mateo–Hayward Bridge to downtown Hayward in the East Bay at its junction with State Route 238 and State Route 185. It has interchanges with three freeways: Interstate 280, U.S. Route 101 in or near San Mateo, and Interstate 880 in Hayward. It also connects indirectly to Interstates 238 and 580 by way of Hayward's Foothill Boulevard, which carries Route 238 and flows directly into Route 92.
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.
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.

U.S. Route 101 Business is a business loop of U.S. Route 101 that runs along Wildwood Avenue in Rio Dell in Humboldt County, California. Its southernmost section between US 101 near Scotia to the north end of the Eel River Bridge is legally defined as an unsigned state highway, State Route 283. The route was defined in 1970 as a transfer from a realigned US 101 after a freeway bypass was built.
State Route 130 is a state highway in Santa Clara County, California that connects San Jose with the Lick Observatory on Mount Hamilton. The highway follows Mount Hamilton Road, a narrow two-lane highway that goes through the Diablo Range. Legislatively, SR 130 extends east from Mount Hamilton to Patterson in Stanislaus County, forming a route between the Santa Clara and San Joaquin valleys, but the traversable route via San Antonio Valley Road and Del Puerto Canyon Road is maintained at the county level and has not yet been formally adopted by the California Department of Transportation (Caltrans).
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 103 is a state highway in the U.S. state of California that forms part of the Terminal Island Freeway in Los Angeles and Long Beach.

Heim Bridge to its end at Ocean Boulevard on Terminal Island, at the former Long Beach Naval Shipyard. SR 47 then turns west there to its end at Interstate 110.
State Route 129 is a state highway in the U.S. state of California, connecting State Route 1 in Watsonville in Santa Cruz County with U.S. Route 101 near San Juan Bautista in San Benito County.

Also, in conjunction with SR 58 and SR 41, it provides a slower, more scenic route between the Central Coast and the San Joaquin Valley.
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.
State Route 222, named Talmage Road along its entire length, is an unsigned state highway in the U.S. state of California. It was originally constructed as a short spur route of U.S. Route 101 in Mendocino County to what was the Mendocino State Hospital in Talmage. The road has remained a state highway after the hospital closed down and the City of Ten Thousand Buddhas monastery was established on the former site in 1976. The SR 222 designation legislatively ends at its intersection with East Side Road, where the road continues as Bodhi Way into the monastery complex.
State Route 223, locally known as Bear Mountain Boulevard, is a state highway in the U.S. state of California that runs west to east through the agricultural land south of Bakersfield in Kern County. Running from Interstate 5 (I-5) to State Route 58 near the city of Arvin, it also intersects with State Route 99 near Greenfield. SR 223 forms a truck route for transporting goods to the three main corridors in the area, I-5, SR 58 and SR 99, without having to drive through Bakersfield.
