State Route 1 (SR 1), more often called Highway 1, is a state highway that runs along much of the Pacific coast of the U.S. state of California. It is famous for running along some of the most beautiful coastlines in the world, leading to its designation as an All-American Road.
Highway 1 does not run over the entire Pacific coastline of California. It starts at Interstate 5 (I-5) near Dana Point in Orange County and runs north to U.S. Highway 101 (US 101) near Leggett in Mendocino County. Highway 1 also at times runs concurrently with US 101, most notably through a 54-mile (87 km) stretch in Ventura and Santa Barbara Counties, and across the Golden Gate Bridge. It also serves as a scenic alternative in several locations; and a major thoroughfare in the Greater Los Angeles Area, the San Francisco Bay Area, and other coastal urban areas along its route.
Highway 1 has several portions designated as either Pacific Coast Highway (PCH), the Cabrillo Highway, the Shoreline Highway, or the Coast Highway.

Highway 1 is part of the California Freeway and Expressway System[2] and is eligible for the State Scenic Highway System.[3] However, only a few stretches between Los Angeles and San Francisco have officially been designated as a scenic highway.[4] The Big Sur section from San Luis Obispo to Carmel is an official National Scenic Byway.[5]
The entire route is also designated as a Blue Star Memorial Highway to recognize those in the United States armed forces. In Southern California, the California Legislature has designated the segment between Interstate 5 (I-5) in Dana Point and US 101 near Oxnard as the Pacific Coast Highway (commonly referred to as "PCH"). Between U.S. 101 at the Las Cruces junction (8 miles south of Buellton) and U.S. 101 in Pismo Beach, and between U.S. 101 in San Luis Obispo and Interstate 280 in San Francisco, the legislature has designated State Highway 1 as the Cabrillo Highway, after Portuguese explorer Juan Rodríguez Cabrillo. The legislature has also designated the route as the Shoreline Highway between the Manzanita Junction near Marin City and Leggett. Smaller segments of the highway have been assigned several other names by the state and municipal governments.[6]
In addition to connecting the coastal cities and communities along its path, Highway 1 also provides access to numerous beaches, parks, and other attractions along the coast, making it a popular route for tourists. The route runs right besides the coastline, or close to it, for the most part, but it also turns several miles inland to avoid several federally-controlled or protected areas such as Vandenberg Air Force Base, Diablo Canyon Power Plant and Point Reyes National Seashore.
At its southernmost end in Orange County, Highway 1 terminates at I-5 in Capistrano Beach in Dana Point. It then travels north into the city center, where, for about 1 mile (1.6 km), northbound traffic continues along the original PCH alignment and southbound traffic is diverted onto the parallel Del Prado. After the two roads merge back, Highway 1 continues north along the coast through Laguna Beach and Crystal Cove State Park.
Highway 1 then enters Newport Beach, where it is known as simply Coast Highway. It passes through several affluent neighborhoods, including Newport Coast and Corona Del Mar, and spans the entrance to the Upper Newport Bay. Upon entering Huntington Beach, Highway 1 regains the Pacific Coast Highway designation. It passes Huntington State Beach before reaching Bolsa Chica State Beach and the Bolsa Chica Ecological Reserve. PCH then continues along the coast into Seal Beach, the final city on its journey in Orange County.
PCH enters Los Angeles County and the city of Long Beach after crossing the San Gabriel River. Highway 1 then continues northwest through the city to its junction with Lakewood Boulevard (State Route 19) and Los Coyotes Diagonal at the Long Beach Traffic Circle, more than 2 miles (3.2 km) from the coast. From the traffic circle, it continues inland west through Long Beach, including approximately one mile adjacent to the southern boundary of Signal Hill. PCH then passes through the Los Angeles districts of Wilmington and Harbor City. While bypassing the immediate coastline of Palos Verdes, Highway 1 continues to head west into the cities of Lomita and Torrance.
PCH then turns north through Redondo Beach and Hermosa Beach. Upon entering Manhattan Beach, it becomes Sepulveda Boulevard and continues through El Segundo and Los Angeles International Airport (LAX), passing under two runways via the Sepulveda Boulevard Tunnel.
After leaving LAX, State Highway 1 turns northwest, becoming Lincoln Boulevard and passing through the Los Angeles neighborhoods of Westchester, Playa Vista, Marina Del Rey, and Venice. It then enters the city of Santa Monica, where Highway 1 turns southwest, merging onto the final segment of the Santa Monica Freeway. Passing through the McClure Tunnel, Highway 1 emerges along the beachfront in Santa Monica and continues along the coast; it is known locally also as Palisades Beach Road and formerly as Roosevelt Highway. Upon leaving Santa Monica, it once again regains the name PCH as it follows the coast, curving west through the Pacific Palisades neighborhood before becoming Malibu's main thoroughfare, spanning the entire 21 miles (34 km) of that city.
After leaving Malibu, Highway 1 crosses into Ventura County and continues along the coast through Point Mugu State Park to just beyond the park's western boundary. Approaching the Oxnard Plain, it passes through a notch in the mountain that forms Point Mugu. The road cut left a very large rock formation at the tip of the point that is called the Mugu Rock. At that point, PCH leaves the coast and heads north, and then northwest as a freeway along the northeastern boundary of Naval Base Ventura County Point Mugu for several miles to an interchange at Rice Avenue, Pleasant Valley Road, and Oxnard Boulevard in Oxnard. From there, Highway 1 continues northwest onto Oxnard Boulevard to Wooley Road, then heads due north further inland to US 101, where it begins its first concurrency with that U.S. Route.
After traveling through Ventura, Highway 1 separates from US 101 to travel along the beach from Emma Wood State Beach to the Mobil Pier Undercrossing, where it rejoins US 101 about 3 miles (4.8 km) south of the Santa Barbara County line near La Conchita.
The US 101/Highway 1 concurrency (although actual signage mentioning Highway 1 through this segment is nonexistent) from the Mobil Pier Undercrossing runs for 54 miles (87 km), passing through the City of Santa Barbara and its neighboring communities along the coast of Santa Barbara County. Afterwards, Highway 1, now named Cabrillo Highway, splits again from US 101 north of the Gaviota Tunnel, and heads to the coastal city of Lompoc. It is briefly joined with Highway 246 along Lompoc's east-west Ocean Avenue, before turning north as H Street to Harris Grade Road, where it then regains the Cabrillo Highway name.
After reaching Vandenberg Air Force Base, Highway 1 turns inland, northeast, to join Highway 135. Route 135 then splits from Route 1 south of Orcutt, and the Cabrillo Highway turns northwest back towards the coast to Guadalupe. It then enters San Luis Obispo County, passing through Grover Beach before joining US 101 for the third time at Pismo Beach.
Highway 1 then splits from US 101 at San Luis Obispo and resumes as the Cabrillo Highway. It runs through Morro Bay as a freeway, where it crosses Morro Creek at the site of a prehistoric Chumash settlement dating to the Millingstone Horizon.[7] From there, Highway 1 proceeds north to Cayucos until it again becomes a winding, two lane road with occasional passing lanes. It then continues along the coast through San Simeon and past the elephant seal colony at Piedras Blancas Light.
Highway 1 then enters the Big Sur region, crossing the San Carpoforo Creek just south of the Monterey County line. For about 90 miles (140 km) from the San Carpoforo Creek to the Carmel River, the road winds and hugs the cliffs of Big Sur, passing various coastal parks in the area. This segment of the highway, built between 1919 and 1937, also crosses several historic bridges, including the scenic Bixby Creek Bridge, a reinforced concrete arch with a 320-foot (98 m) span that passes over the Bixby Creek gorge, and the Rocky Creek Bridge.
After crossing the Carmel River, Highway 1 runs along just outside the eastern boundary of Carmel before becoming a freeway in Monterey. The freeway then heads north along the coast of Monterey Bay through Sand City, Seaside, and Marina. At the interchange with Highway 156 near Castroville, Highway 1 continues north as a two-lane rural road to Moss Landing.
Highway 1 becomes a freeway once again just before entering into Santa Cruz County. This four-lane freeway continues up the Monterey Bay through Watsonville to its interchange with Highway 17 in Santa Cruz (the Highway 1/17 interchange is locally known as The Fishhook due to its tight loop ramps that resemble a fishhook when viewed from above). Upon reaching downtown Santa Cruz, it continues as Mission Street and Coast Road, before regaining the Cabrillo Highway name after it leaves the city and continues north as a two lane road up the coast.
Entering San Mateo County, Highway 1 follows the west coast of the San Francisco Peninsula, passing by the marine mammal colonies at the Año Nuevo State Reserve, and the historic Pigeon Point Lighthouse, before reaching Half Moon Bay. Between Half Moon Bay and Pacifica, the highway travels through a treacherous stretch known as Devil's Slide, known for periodic landslides and closures.
Highway 1 then becomes a freeway once again at Sharp Park in Pacifica before turning inland to join Interstate 280 in Daly City. Just short of reaching the City and County of San Francisco, Highway 1 splits from Interstate 280, where the road becomes Junipero Serra Boulevard. Shortly thereafter, the highway makes a slight left, becoming the six-lane wide 19th Avenue. Highway 1 then turns into Park Presidio Boulevard after it passes through the city's Golden Gate Park. Then after entering the Presidio of San Francisco, it goes through the MacArthur Tunnel before joining US 101 for a fourth time on the approach to the Golden Gate Bridge known as Doyle Drive.
After crossing the bridge and entering Marin County, Highway 1 then splits from US 101 again near Marin City, where it leaves the city and, as the Shoreline Highway, returns to a winding, two lane road as it passes over the Marin Hills to rejoin the coast at Muir Beach. Leaving the Golden Gate National Recreation Area, the highway passes the Point Reyes National Seashore and Tomales Bay, eventually entering Sonoma County just south of Bodega Bay, where its name changes to Coast Highway past the Sonoma Coast State Beaches. After bridging the Russian River at Jenner, Highway 1 winds along the rugged coast to Fort Ross and Salt Point State Parks.
Highway 1 then crosses the Gualala River and enters Mendocino County. The highway enters the city of Point Arena, in which it becomes Main Street, before following School Street to the northwest and then becoming Shoreline Highway once again. It bridges the Garcia River and then, near Elk, the Navarro River, where it meets Highway 128.
At the town of Albion, the Albion River is spanned by the Albion River Bridge, the only remaining wooden trestle bridge on the highway. Highway 1 then passes through Little River and Van Damme State Park, crosses Big River and passes through Mendocino Headlands State Park and the Victorian community of Mendocino. Continuing north, Highway 1 crosses Russian Gulch State Park on the Frederick W. Panhorst Bridge, and passes through the town of Caspar. It passes through a roundabout just south of the intersection with the western terminus of State Highway 20,[8][9] where it widens to two lanes, then bridges the Noyo River at Noyo, becomes Main Street of Fort Bragg, and crosses the California Western Railroad.
North of Fort Bragg as a single-lane highway again, the highway passes MacKerricher State Park and the towns of Cleone and Inglenook before crossing Ten Mile River. At Rockport the highway turns away from the Lost Coast to avoid steep and unstable highlands created by Mendocino Triple Junction uplift. The highway follows Cottaneva Creek inland through redwood-forested mountainous terrain before terminating at US 101 just outside Leggett.
California Highway 1 has become a famous brand around the world, but California 1 was called several other names and numbers prior to 1964. When the road was first envisioned in the World War I era, California highways were referred to either by a highway name or by a "Route Number". The route numbers were used by state highway planners and the Legislature from 1915 until 1964, but were never posted on highways, referred to by the auto clubs or public, nor used on maps. The Highway 1 designation was first designated in 1939. Various portions of State Highway 1 have been posted and referred to by various names and numbers over the years. State construction of what became Highway 1 started after the state's third highway bond issue passed before 1910.
One of the most difficult routes to build was along the Big Sur coast. The state first approved building Route 56, or the Carmel-San Simeon Highway,[10] to connect Big Sur to the rest of California in 1919. Federal funds were appropriated and in 1921 voters approved additional state funds. San Quentin Prison set up three temporary prison camps to provide unskilled convict labor to help with road construction. One was set up by Little Sur River, one at Kirk Creek and a third was later established in the south at Anderson Creek. Inmates were paid 35 cents per day and had their prison sentences reduced in return. The route necessitated 33 bridges constructed, the largest of which was the Bixby Creek Bridge. Six more concrete arch bridges were built between Point Sur and Carmel, and all were listed in the National Register of Historic Places in 1986.[11]
After 18 years of construction, aided by New Deal funds during the Great Depression, the paved two-lane road was completed and opened on June 17, 1937.[12] The road was initially called the Carmel-San Simeon Highway (Route 56), but was better known as the Roosevelt Highway, honoring the current President Franklin D. Roosevelt. A 1921 law extended Route 56 south over the county road to Cambria.[13]
Route 60, from Oxnard via the coast to San Juan Capistrano, was extended from Oxnard to El Rio (midway to Ventura, now the site of the Oxnard Boulevard interchange with US 101), in 1925. The 1921 legislation, in theory, made Route 60 a continuous coastal loop, with both ends at what became US 101 in Oxnard and at Capistrano Beach (since 1964 the southern terminus of Highway 1 at Interstate 5 in Orange County).[14] Route 56 was extended further south from Cambria to connect to present-day US 101 in San Luis Obispo in 1931.[15]
The route from San Simeon to Carmel (connecting with existing county highways at each end) was one of two sections designated as Highway 1. It and Route 60 were intended as links in a continuous coastal roadway from Oregon to Mexico,[16][17]
A large expansion of the state highway system in 1933 resulted in Route 56 being extended in both directions. To the south, a second section was added, beginning at Pismo Beach on US 101 (Route 2) and heading south through Guadalupe and Lompoc to rejoin US 101 at a junction called Los Cruces (sic), just north of Gaviota Pass. (A short piece near Orcutt and Los Alamos had been part of Route 2, which originally followed present Highway 135 from Los Alamos to Santa Maria.) To the north, Route 56 was continued along the coast from Carmel through Santa Cruz to San Francisco. Several discontinuous pieces were added north of San Francisco, one from Route 1 (US 101) north of the Golden Gate to the county line near Valley Ford, another from the Russian River near Jenner (where the new Route 104 ended) to Westport, and a third from Ferndale to Route 1 near Fernbridge. Except for the gaps in Route 56 north of San Francisco, these additions completed the coastal highway, with other sections formed by Routes 1, 2, and 71.[18][19]
The section of Highway 1 from Santa Monica to Oxnard, via Malibu, went out to contract in 1925 as "Coast Boulevard" but was designated "Theodore Roosevelt Highway" when it was dedicated in 1929. Before the completion of its present alignment in 1937, a narrow, winding, steep road known as Pedro Mountain Road connected Montara with Pacifica. That highway was completed in 1914 and provided competition to the Ocean Shore Railroad, which operated between San Francisco and Tunitas Creek from 1907 to 1920. Highway 1 also used to run along the coast between Pacifica and Daly City but this segment was damaged and rendered unusable after a 5.3 magnitude earthquake on March 22, 1957. A small stub remains near Thornton Beach.
Route 56 along Big Sur was incorporated into the state highway system and re-designated as Highway 1 in 1939. The section ofroad along the Big Sur Coast was declared the first State Scenic Highway in 1965, and in 1966 the first lady, Mrs. Lyndon B. Johnson, led the official designation ceremony at Bixby Creek Bridge.[20] The route was designated as an All American Road by the US Government.[11]
California Highway 1 signs first went up after California decided to number its highways, in 1934. But only the section from Santa Barbara County north was posted as Highway 1, that section of the road known Route 56 (Las Cruces to Fernbridge, including the gaps). In Ventura, Los Angeles and Orange counties, Route 60 (San Juan Capistrano to the Oxnard area) became California Highway 3, and a few Route 3 signs were actually posted.[21] But the Route 3 signs were replaced by "U.S. Route 101 Alternate" shields and strips by 1936, as the road was built out; this change also allowed the extension of US 66 to end at another U.S. Route, in Santa Monica.[22]
The gaps of non-state highway along the northern coast were finally filled in by the Legislature in 1951, though the State Department of Public Works was not required to maintain the newly-added portions immediately. A short connection from near Rockport to Highway 1 at Leggett was also included,[23] as the existing county road north from Rockport to Ferndale had not yet been paved.[24] The Leggett connection became State Route 208.[25]
The state Legislature in 1963 tossed out the old conflicting Legislative Route Numbers (1964 renumbering), got rid of some famous old U.S. routes (like U.S. 66), and renumbered many state highways. It abolished US 101A in Los Angeles, Orange and Ventura counties and renumbered it as state Highway 1. The cover of "California Highways" magazine in fall 1964 shows state engineers posting the new shield at Point Mugu.[26] The same year, the Legislature by state law named Highway 1 "Pacific Coast Highway" in Orange, Los Angeles and Ventura counties, and "Cabrillo Highway" from San Luis Obispo north to San Francisco. Many cities, however, did not change the name of city streets that are part of Highway 1, such as Lincoln and Sepulveda boulevards in Los Angeles, Santa Monica and El Segundo; Oxnard Boulevard in Oxnard; and Junipero Serra and Park Presidio boulevards in San Francisco.
The freeway portion of Highway 1 from Highway 68 in Monterey to Munras Avenue opened in 1960. The segment from Munras Avenue to the northern border of Sand City and Seaside opened in 1968, and bypasses the original highway alignment of Munras Avenue and Fremont Street in Monterey, and Fremont Boulevard through Seaside. North of Seaside, the freeway was built over the original Highway 1 alignment through Fort Ord in 1973. North of Fort Ord, Highway 1 now veers to the left of the original alignment and bypasses Marina to the west. This segment including the interchange with Highway 156 and the short, 2-lane Castroville Bypass opened in 1976. Originally Highway 1 followed the Highway 156 alignment to the Highway 183 intersection in Castroville, then turned northwest, following the present-day Highway 183 through Castroville before rejoining its existing alignment at the northern terminus of the Castroville Bypass.
In 1980, another section was added northwest of Ventura, when several miles of the old two-lane alignment of US 101 were posted as Highway 1 where the freeway had bypassed it in about 1960. At its northern terminus, in 1984 State Highway 1 replaced State Highway 208, with the old alignment to Fernbridge, never constructed south of Ferndale, becoming State Highway 211.[27] This part of the Pacific coast, the only long section in California not served by a state highway, has been termed California's "Lost Coast".
For the 1932 Summer Olympics, the segment of the Highway 1 between Oxnard and Santa Monica (then known as the Theodore Roosevelt Highway) hosted part of the road cycling events.[28]
Frequent California landslides and erosion along the coast have caused portions of Highway 1 to either be closed for long periods of time, or be re-routed entirely. Some of these examples include:
There is a future plan to re-route Highway 1 in Oxnard. Once a new Rice Avenue-US 101 interchange is completed, PCH between Pleasant Valley Road and US 101 will be moved from Oxnard Blvd onto Rice.
