'''State Route&nbsp;1''' ('''SR&nbsp;1''') is a major north–south [[state highway]] that runs along most of the [[West Coast of the United States|Pacific coastline]] of the U.S. state of [[California]]. At {{convert|656|mi|km}}, it is the longest state route in California, and the [[List of longest state highways in the United States|second-longest in the US]] after [[Montana Highway 200]]. SR&nbsp;1 has several portions designated as either '''Pacific Coast Highway''' ('''PCH'''), '''Cabrillo Highway''', '''Shoreline Highway''', or '''Coast Highway'''. Its southern terminus is at [[Interstate 5 in California|Interstate 5]] (I-5) near [[Dana Point, California|Dana Point]] in [[Orange County, California|Orange County]] and its northern terminus is at [[U.S. Route 101 in California|U.S. Route 101]] (US&nbsp;101) near [[Leggett, California|Leggett]] in [[Mendocino County, California|Mendocino County]]. SR&nbsp;1 also at times runs [[concurrency (road)|concurrently]] with US&nbsp;101, most notably through a {{convert|54|mi|km||adj=mid}} stretch in [[Ventura County, California|Ventura]] and [[Santa Barbara County, California|Santa Barbara]] counties, and across the [[Golden Gate Bridge]].

The highway is designated as an [[National Scenic Byway|All-American Road]]. In addition to providing a scenic route to numerous attractions along the coast, the route also serves as a major thoroughfare in the [[Greater Los Angeles Area]], the [[San Francisco Bay Area]], and several other coastal urban areas. Though some maps and signs mark SR&nbsp;1 as continuous through the cities of [[Dana Point, California|Dana Point]], [[Newport Beach, California|Newport Beach]], [[Santa Monica, California|Santa Monica]], and [[Oxnard, California|Oxnard]], control of segments within those cities were relinquished to those local jurisdictions and are thus no longer officially part of the state highway system. The Golden Gate Bridge is also officially not included in the state highway system because it is maintained locally by the [[Golden Gate Bridge, Highway and Transportation District]].

SR&nbsp;1 was built piecemeal in various stages, with the first section opening in the [[Big Sur]] region in the 1930s. However, portions of the route had several names and numbers over the years as more segments opened. It was not until the [[1964 state highway renumbering (California)|1964 state highway renumbering]] that the entire route was officially designated as SR&nbsp;1. Although SR&nbsp;1 is a popular route for its scenery, frequent landslides and erosion along the coast have caused several segments to be either closed for lengthy periods for repairs, or re-routed inland.

==Route description== <!--Route descriptions should be written in a present-day perspective. Any changes or significant events may be indicated in the History section.-->
Due to its fragmented nature and piecemeal relinquishments, the [[California Codes|California Streets and Highways Code]] defines Route 1 across several subdivisions of section 301 as follows:<ref name="CSHC301">{{Cite web|url=https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=SHC&sectionNum=301.|title=Section 301|work=California Streets and Highways Code|publisher=California Office of Legislative Counsel|location=Sacramento|access-date=August 17, 2025}}</ref>
<blockquote>Route 1 is from:

(a) [[Interstate 5 (California)|Route&nbsp;5]] south of [[San Juan Capistrano, California|San Juan Capistrano]] to [[U.S. Route 101 in California|Route 101]] near [[El Rio, California|El Rio]] except for the portions of Route 1 relinquished:

(b) Route 101 at [[Emma Wood State Beach]], 1.3 miles north of [[California State Route 33|Route 33]], to Route 101, 2.8 miles south of the [[Ventura County, California|Ventura]]-[[Santa Barbara County, California|Santa Barbara]] county line at Mobil Pier Undercrossing.<br/>(c) Route 101 near [[Las Cruces, California|Las Cruces]] to Route 101 in [[Pismo Beach, California|Pismo Beach]] via the vicinity of [[Lompoc, California|Lompoc]], [[Vandenberg Air Force Base]], and [[Guadalupe, California|Guadalupe]].<br/>(d) Route 101 in [[San Luis Obispo, California|San Luis Obispo]] to [[Interstate 280 (California)|Route 280]] south of [[San Francisco]] along the coast via [[Cambria, California|Cambria]], [[San Simeon, California|San Simeon]], and [[Santa Cruz, California|Santa Cruz]].<br/>(e) Route 280 near the south boundary of the [[San Francisco|City and County of San Francisco]] to Route 101 near the approach to the [[Golden Gate Bridge]] in San Francisco.<br/>(f) Route 101 near the southerly end of Marin Peninsula to Route 101 near [[Leggett, California|Leggett]] via the coast route through [[Jenner, California|Jenner]] and [[Westport, California|Westport]].</blockquote>

The definition omits Route 1's [[Concurrency (road)|concurrencies]] with Routes 101 and 280 instead of duplicating those segments in the other routes' definitions in the code. And while the former portions of Route 1 have been relinquished by the state to the cities of Dana Point, Newport Beach, Santa Monica, and Oxnard, section 301 subdivision (g) further mandates that those cities must still "maintain within their respective jurisdictions signs directing motorists to the continuation of Route 1".<ref name="CSHC301"/> In addition to the relinquished portions listed under subdivision (a), sections 301 subdivision (h), 301.1, 301.3, 303.4 and 301.5 of the code permit the state to relinquish select or all portions of Route 1 in the cities of [[Los Angeles]], [[Torrance, California|Torrance]], Newport Beach, [[Laguna Beach, California|Laguna Beach]] and Pismo Beach respectively.<ref name="CSHC301.1">{{Cite web|url=https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=SHC&sectionNum=301.1.|title=Section 301.1|work=California Streets and Highways Code|publisher=California Office of Legislative Counsel|location=Sacramento|access-date=August 17, 2025}}</ref><ref name="CSHC301.3">{{Cite web|url=https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=SHC&sectionNum=301.3.|title=Section 301.3|work=California Streets and Highways Code|publisher=California Office of Legislative Counsel|location=Sacramento|access-date=August 17, 2025}}</ref><ref name="CSHC301.4">{{Cite web|url=https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=SHC&sectionNum=301.4.|title=Section 301.4|work=California Streets and Highways Code|publisher=California Office of Legislative Counsel|location=Sacramento|access-date=August 17, 2025}}</ref><ref name="CSHC301.5">{{Cite web|url=https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=SHC&sectionNum=301.5.|title=Section 301.5|work=California Streets and Highways Code|publisher=California Office of Legislative Counsel|location=Sacramento|access-date=August 17, 2025}}</ref>

The entire route is designated as a [[Blue Star Memorial Highway]] to recognize those in the United States armed forces; this designation is sponsored by the California Garden Clubs, but the organization has not erected such markers along SR&nbsp;1 yet.<ref>{{cite web |author = California Department of Transportation  |url = https://dot.ca.gov/programs/design/lap-landscape-architecture-and-community-livability/lap-liv-a-blue-star-memorial-highways |title = Blue Star Memorial Highways |publisher = California Department of Transportation|access-date = November 2, 2021 |archive-url = https://web.archive.org/web/20210827040720/https://dot.ca.gov/programs/design/lap-landscape-architecture-and-community-livability/lap-liv-a-blue-star-memorial-highways |archive-date =August 27, 2021 |url-status = live }}</ref> In 1959, the legislature officially designated the segment in Southern California between [[Interstate 5 in California|Interstate 5]] (I-5) in [[Dana Point, California|Dana Point]] and [[U.S. Route 101 in California|US&nbsp;101]] near [[Oxnard, California|Oxnard]] as the Pacific Coast Highway (commonly referred to as "PCH", without the definite article "the", unlike other [[California English#Freeways|freeway numbers in the Los Angeles area]]). Between US&nbsp;101 at the Las Cruces junction ({{convert|8|mi|disp=sqbr}} south of [[Buellton, California|Buellton]]) and US&nbsp;101 in [[Pismo Beach, California|Pismo Beach]], and between US&nbsp;101 in [[San Luis Obispo, California|San Luis Obispo]] and [[Interstate 280 (California)|Interstate 280]] in San Francisco, the legislature also designated SR&nbsp;1 as the Cabrillo Highway in 1959, after the explorer [[Juan Rodríguez Cabrillo]] who sailed along the coast line. The legislature also designated the route as the Shoreline Highway in 1957 between the Manzanita Junction near [[Marin City, California|Marin City]] and [[Leggett, California|Leggett]]. Smaller segments of the highway have been assigned several other names by the state and municipal governments.<ref>{{cite book |author = California Department of Transportation  |url = http://www.dot.ca.gov/hq/tsip/hseb/products/Named_Freeways.pdf |title = 2007 Named Freeways, Highways, Structures and Other Appurtenances in California |publisher = California Department of Transportation |pages = 5, 69, 115–116 |access-date = March 28, 2007 |archive-url = https://web.archive.org/web/20130523161116/http://dot.ca.gov/hq/tsip/hseb/products/Named_Freeways.pdf |archive-date = May 23, 2013 |url-status = live }}</ref>

For the most part, SR&nbsp;1 runs parallel to the coastline, or close to it, but does turn several miles inland at various locations to avoid several federally controlled or protected areas such as [[Vandenberg Space Force Base]], [[Diablo Canyon Power Plant]] and [[Point Reyes National Seashore]]. In addition to connecting the coastal cities and communities along its path, the route provides access to beaches, parks, and other attractions along the coast, making it a popular route for tourists. The route annually helps bring several billion dollars to the state's tourism industry.<ref>{{cite magazine |last = Miller |first = Heather |date = June 1999 |title = The Ups and Downs of Highway 1 |url = http://www.smithsonianmag.com/travel/highway-abstract.html |archive-url = https://archive.today/20130702053412/http://www.smithsonianmag.com/travel/highway-abstract.html |url-status = dead |archive-date = July 2, 2013 |magazine = [[Smithsonian (magazine)|Smithsonian Magazine]] |access-date = July 2, 2013 }}</ref> Segments of SR&nbsp;1 range from urban freeway to simple rural two-lane road.

===Orange County===
At its southernmost end in [[Orange County, California|Orange County]], SR&nbsp;1 terminates at I-5 in [[Capistrano Beach, Dana Point, California|Capistrano Beach]] in [[Dana Point, California|Dana Point]]. It then travels west into the city center. After leaving Dana Point, Pacific Coast Highway (PCH) becomes simply "Coast Highway" while at the same time continuing northwest along the coast through [[Laguna Beach, California|Laguna Beach]] (where it meets the southern terminus of [[California State Route 133|SR&nbsp;133]]) and [[Crystal Cove State Park]].<ref name="CA2010map" /><ref name="google" />

SR&nbsp;1 then enters [[Newport Beach, California|Newport Beach]] and passes through several affluent neighborhoods, including [[Newport Coast]] and [[Corona del Mar, Newport Beach, California|Corona Del Mar]], spans the entrance to the [[Upper Newport Bay]], which marks the boundary between East Coast Highway and West Coast Highway, and crosses [[California State Route 55]] near its southern terminus. Upon crossing the [[Santa Ana River]] mouth and entering [[Huntington Beach, California|Huntington Beach]], SR&nbsp;1 regains the Pacific Coast Highway designation. It passes [[Huntington State Beach]] and the southern terminus of [[California State Route 39]] before reaching [[Bolsa Chica State Beach]] and the [[Bolsa Chica Ecological Reserve]]. PCH then continues along the coast into [[Seal Beach, California|Seal Beach]], the final city on its journey in Orange County.<ref name="CA2010map" /><ref name="google" />

===Los Angeles and Ventura counties===
[[File:The Pacific Coast Towers.jpg|thumb|The Pacific Corporate Towers alongside PCH in El Segundo, California]]
PCH enters [[Los Angeles County, California|Los Angeles County]] and the city of [[Long Beach, California|Long Beach]] after crossing the [[San Gabriel River (California)|San Gabriel River]]. SR&nbsp;1 then continues northwest through the city to its junction with [[California State Route 19|Lakewood Boulevard]] (State Route 19) and Los Coyotes Diagonal at the [[Los Alamitos Circle]], more than {{convert|2|mi|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, California|Signal Hill]]. PCH is marked as such in Long Beach, but originally bore the name of Hathaway Avenue east of the traffic circle and State Street west of there. PCH then passes through the [[List of districts and neighborhoods of Los Angeles|Los Angeles districts]] of [[Wilmington, Los Angeles|Wilmington]] and [[Harbor City, Los Angeles|Harbor City]]. While bypassing the immediate coastline of [[Palos Verdes]], SR&nbsp;1 continues to head west into the cities of [[Lomita, California|Lomita]] and [[Torrance, California|Torrance]] along the route of the former Redondo-Wilmington Boulevard.<ref name="CA2010map" /><ref name="google" />

PCH then turns north through [[Redondo Beach, California|Redondo Beach]] and [[Hermosa Beach, California|Hermosa Beach]]. Upon entering [[Manhattan Beach, California|Manhattan Beach]], it becomes [[Sepulveda Boulevard]] and turns back into PCH designation through [[El Segundo, California|El Segundo]].<ref>{{cite news|url=https://www.dailybreeze.com/2018/06/04/el-segundo-says-goodbye-to-sepulveda-boulevard-hello-to-pch/|title=El Segundo says goodbye to Sepulveda Boulevard, hello to PCH|first=Megan|last=Barnes|newspaper=[[Daily Breeze]]|date=June 4, 2018|access-date=June 5, 2018|archive-url=https://web.archive.org/web/20180719053910/https://www.dailybreeze.com/2018/06/04/el-segundo-says-goodbye-to-sepulveda-boulevard-hello-to-pch/|archive-date=July 19, 2018|url-status=dead}}</ref> At Imperial Highway, it regains the name Sepulveda Boulevard as it descends and passes under two runways of [[Los Angeles International Airport]] (LAX) via the [[Airport Tunnel (Los Angeles)|Airport Tunnel]].<ref name="CA2010map" /><ref name="google" />

[[File:Ca-1 between Santa Monica and LAX.JPG|thumb|left|Southbound SR&nbsp;1 near the intersection of Lincoln and Sepulveda Boulevards north of LAX]]
After leaving LAX, SR&nbsp;1 splits from Sepulveda and turns northwest, becoming [[Lincoln Boulevard (Southern California)|Lincoln Boulevard]] and passing through the Los Angeles neighborhoods of [[Westchester, Los Angeles|Westchester]], [[Playa Vista, Los Angeles|Playa Vista]], and [[Venice, Los Angeles|Venice]], as well as the unincorporated community of [[Marina del Rey, California|Marina Del Rey]]. This portion of SR 1 suffers heavy congestion at most times due to the shortage of alternate north-south arterial roads west of [[Interstate 405 (California)|Interstate 405]].  It then enters the city of [[Santa Monica, California|Santa Monica]], where SR&nbsp;1 turns southwest, merging onto the westernmost segment of the [[Interstate 10 in California#Santa Monica Freeway|Santa Monica Freeway]]. Passing through the [[McClure Tunnel]] (which also serves as the national western terminus of [[Interstate 10]]), SR&nbsp;1 emerges along the beachfront in Santa Monica as PCH again and continues along the coast, separated from Downtown Santa Monica by the palisades north of [[Santa Monica Pier]]; this portion is also known locally as Palisades Beach Road and formerly as Roosevelt Highway. Upon leaving Santa Monica, PCH continues to follow the coast, curving west through the [[Pacific Palisades, Los Angeles|Pacific Palisades]] neighborhood of Los Angeles before becoming the main thoroughfare of the city of [[Malibu, California|Malibu]] while traversing the entire {{convert|21|mi|km}} of that city.<ref name="CA2010map" /><ref name="google" />

[[File:Mugu Rock on California Route 1.jpg|left|thumb|PCH passing Mugu Rock at Point Mugu]]
SR&nbsp;1 crosses the county line and continues through the [[Ventura County, California|Ventura County]] portion of the Malibu coast through [[Leo Carrillo State Park]] and [[Point Mugu State Park]]. After passing through a notch in the promontory that marks [[Point Mugu, California|Point Mugu]], the western end of the [[Santa Monica Mountains]], and the beginning of the [[Oxnard Plain]]. 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 Air Station Point Mugu|Naval Base Ventura County Point Mugu]] for several miles to an interchange at Rice Avenue, Pleasant Valley Road, and Oxnard Boulevard in [[Oxnard, California|Oxnard]].<ref name="CA2010map" /><ref name="google" /> The reconstructed interchange at Rice Avenue and Pleasant Valley Road channels traffic north on the surface street, Rice Avenue, towards the interchange with US&nbsp;101. The historic route along Oxnard Boulevard was relinquished in 2014. Truck traffic to and from the [[Port of Hueneme]] also uses this designated route at the Rice Avenue/Hueneme Road connector to connect with Route 101 at the Rice Avenue Interchange.<ref>{{cite news |url = https://www.latimes.com/archives/la-xpm-1996-01-26-me-28792-story.html |title = City, County to Jointly Seek U.S. Funds for Freeway Link |work =Los Angeles Times |date = January 26, 1996 |first = Nick |last = Green |access-date = April 8, 2015 |archive-url = https://web.archive.org/web/20150418125338/http://articles.latimes.com/1996-01-26/local/me-28792_1_county-action |archive-date = April 18, 2015 |url-status = live }}</ref>

After traveling through [[Ventura, California|Ventura]], SR&nbsp;1 separates from US&nbsp;101 to travel the [[Rincon Sea Level Road|historic beach route]] along the Rincon coast that was originally opened up by the construction of the [[Coast Line (Union Pacific Railroad)|Railroad Coastal Route]] from [[Emma Wood State Beach]] to the Mobil Pier Undercrossing near [[Sea Cliff, California|Sea Cliff]], where it rejoins US&nbsp;101 about {{convert|3|mi|km}} south of the [[Santa Barbara County, California|Santa Barbara County]] line near [[La Conchita, California|La Conchita]].<ref name="CA2010map" /><ref name="google" />

===Central Coast===
The US&nbsp;101/SR&nbsp;1 concurrency (although actual signage mentioning SR&nbsp;1 through this segment is nonexistent) from the Mobil Pier Undercrossing runs for {{convert|54|mi|km}}, passing through the City of [[Santa Barbara, California|Santa Barbara]] and its neighboring communities along the coast of Santa Barbara County. The route then turns away from the [[Gaviota Coast]] at [[Gaviota State Beach]], avoiding [[Point Conception]], and heads due north through [[Gaviota State Park]] and the [[Gaviota Tunnel]]. In [[Las Cruces, California|Las Cruces]], SR&nbsp;1, now named Cabrillo Highway, splits again from US&nbsp;101 and heads northwest to the city of [[Lompoc, California|Lompoc]]. It is briefly joined with [[California State Route 246|SR&nbsp;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.<ref name="CA2010map" /><ref name="google" />

After reaching the main entrance to [[Vandenberg Space Force Base]], SR&nbsp;1 turns northeast, away from the immediate coastline of the base, to join [[California State Route 135|SR&nbsp;135]]. SR&nbsp;135 then splits from SR&nbsp;1 south of [[Orcutt, California|Orcutt]], and the Cabrillo Highway turns northwest back towards the coast to [[Guadalupe, California|Guadalupe]]. It enters [[San Luis Obispo County, California|San Luis Obispo County]], avoiding the immediate coastline of the protected [[Guadalupe-Nipomo Dunes]], before passing through [[Grover Beach, California|Grover Beach]] and subsequently joining US&nbsp;101 for the third time at [[Pismo Beach, California|Pismo Beach]]. The US&nbsp;101/SR&nbsp;1 concurrency then avoids the immediate coastline of [[Avila Beach, California|Avila Beach]] and [[Diablo Canyon Power Plant]], and instead heads straight inland to [[San Luis Obispo, California|San Luis Obispo]].<ref name="CA2010map" /><ref name="google" />

SR&nbsp;1 then enters the [[Big Sur]] region, crossing [[San Carpóforo Canyon|San Carpóforo Creek]] just south of the [[Monterey County, California|Monterey County]] line. For about {{convert|72|mi|km}} from San Carpóforo Creek to [[Malpaso Creek]], the road winds and hugs the cliffs of Big Sur, passing various coastal parks in the area, with no connection to the other side of the [[Santa Lucia Mountains]] except for [[Nacimiento-Fergusson Road]]. The road briefly leaves the coast for a few miles, passing through a redwood forest in the Big Sur River valley. The Big Sur segment of the highway, built between 1919 and 1937, also crosses a number of historic bridges, including the scenic [[Bixby Bridge]], a reinforced concrete arch with a {{convert|320|ft|m|adj=on}} span that passes over the Bixby Creek gorge, the [[Rocky Creek Bridge (California)|Rocky Creek Bridge]],<ref name="CA2010map" /><ref name="google"/> and the [[Big Creek Bridge (California)|Big Creek Bridge]].<ref name="Big Creek Bridge Data">{{cite web|url=https://bridgehunter.com/ca/monterey/440056/|title=Big Creek Bridge|website=Bridgehunter.com|access-date=September 3, 2018|archive-url=https://web.archive.org/web/20180903215455/https://bridgehunter.com/ca/monterey/440056/|archive-date=September 3, 2018|url-status=dead}}{{self-published inline|certain=yes|date=August 2021}}</ref>  The segment of SR 1 through Big Sur is "considered one of the most beautiful drives in the world" and "attracts tourists from all over the world".<ref name="Steakley_Page9">{{cite book |last1=Steakley |first1=Douglas |title=Photographing Big Sur: Where to Find Perfect Shots and How to Take Them |date=2011 |publisher=The Countryman Press |location=Woodstock, Vermont |isbn=9781581579413 |page=9 |url=https://books.google.com/books?id=zKm2SxU1FK4C&pg=PA9}}</ref>

===Monterey Bay Area===
After crossing the Carmel River, SR&nbsp;1 turns inland and runs along the eastern boundary of [[Carmel-by-the-Sea, California|Carmel]] and the western boundary of [[Carmel Valley, California|Carmel Valley]] before becoming a freeway in [[Monterey, California|Monterey]]. After bypassing the immediate coastline of [[Pebble Beach, California|Pebble Beach]] and the rest of the [[Monterey Peninsula]], the freeway heads north along the coast of [[Monterey Bay]] through [[Sand City, California|Sand City]], [[Seaside, California|Seaside]], and [[Marina, California|Marina]]. At the interchange with [[California State Route 156|SR&nbsp;156]] near [[Castroville, California|Castroville]], SR&nbsp;1 continues north as a two-lane rural road to [[Moss Landing, California|Moss Landing]].<ref name="CA2010map" /><ref name="google" />

SR&nbsp;1 becomes a freeway once again just before entering into [[Santa Cruz County, California|Santa Cruz County]]. This four-lane freeway continues up the Monterey Bay coast through [[Watsonville, California|Watsonville]] to its interchange with [[California State Route 17|SR&nbsp;17]] in [[Santa Cruz, California|Santa Cruz]]. (This [[Interchange (road)#Trumpet interchange|trumpet interchange]] is locally known as The Fishhook due to its tight loop ramps that resemble a fishhook when viewed from above). After a short expressway section, it skirts downtown Santa Cruz as four-lane Mission Street, regaining the Cabrillo Highway designation (local/historic name is "Coast Road") after it leaves the city and continues north-west as a two-lane road (with occasional four-lane sections) up the coast through [[Davenport, California|Davenport]].<ref name="CA2010map" /><ref name="google" />

===San Francisco Bay Area===
[[File:Hfb-scene.jpg|left|thumb|Scene from SR&nbsp;1 near Half Moon Bay at [[Tunitas Creek Beach]]]]
Entering [[San Mateo County, California|San Mateo County]], SR&nbsp;1 follows the west coast of the [[San Francisco Peninsula]], passing by the marine mammal colonies at [[Año Nuevo State Park]], and the historic [[Pigeon Point Lighthouse]], before reaching [[Half Moon Bay, California|Half Moon Bay]]. Between Half Moon Bay and [[Pacifica, California|Pacifica]], the highway bypasses a treacherous stretch known as [[Devil's Slide (California)|Devil's Slide]] via the [[Tom Lantos Tunnels]].<ref name="CA2010map" /><ref name="google" />

[[File:Golden Gate Bridge Front Traffic.jpeg|thumb|left|The Golden Gate Bridge, which SR&nbsp;1 shares with US&nbsp;101]]
[[File:California State Route 1 in Marin County.jpg|thumb|left|SR&nbsp;1 winds along the Marin County coast]]
SR&nbsp;1 then becomes a freeway once again at Sharp Park in Pacifica before turning inland to join [[Interstate 280 (California)|Interstate 280]] in [[Daly City, California|Daly City]]. Just short of reaching the City and County of [[San Francisco]], SR&nbsp;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 (San Francisco)|19th Avenue]]; the [[San Francisco Municipal Railway]]'s [[M Ocean View]] [[streetcar]] line runs in the median from this point until a junction to a rail only right-of-way near Rossmoor Drive. SR&nbsp;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&nbsp;101 for a fourth time on the approach to the [[Golden Gate Bridge]] known as Doyle Drive.<ref name="CA2010map" /><ref name="google" />

After crossing the bridge and entering [[Marin County, California|Marin County]], SR&nbsp;1 then splits from US&nbsp;101 again near [[Marin City, California|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, California|Muir Beach]]. After passing [[Stinson Beach, California|Stinson Beach]] and the [[Bolinas Lagoon]], SR&nbsp;1 avoids the immediate coastline of [[Point Reyes National Seashore]] and the rest of the [[Point Reyes|Point Reyes Peninsula]], and instead heads towards, and then along, the eastern shore of [[Tomales Bay]].<ref name="CA2010map" /><ref name="google" />

Leaving Tomales Bay, SR&nbsp;1 heads further inland to intersect with Valley Ford Road just north of the [[Sonoma County, California|Sonoma County]] border. It then rejoins the coast in [[Bodega Bay, California|Bodega Bay]], where its name changes to Coast Highway past the [[Sonoma Coast State Beach]]es. After bridging the [[Russian River (California)|Russian River]] at [[Jenner, California|Jenner]], SR&nbsp;1 continues to wind along the rugged coast to [[Fort Ross, California|Fort Ross]], [[Salt Point State Park]]s, and the planned community of [[Sea Ranch, California|Sea Ranch]].<ref name="CA2010map" /><ref name="google" />

===Mendocino County===
[[File:Russian Gulch Beach.jpg|thumb|SR&nbsp;1 crosses Russian Gulch State Park on the Frederick W. Panhorst Bridge]]
SR&nbsp;1 then crosses the [[Gualala River]] and enters [[Mendocino County, California|Mendocino County]]. The highway enters the city of [[Point Arena, California|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, Mendocino County, California|Elk]], the [[Navarro River]], where it meets [[California State Route 128|SR&nbsp;128]].<ref name="CA2010map" /><ref name="google" />

At the town of [[Albion, California|Albion]], the [[Albion River]] is spanned by the [[Albion River Bridge]], the only remaining wooden trestle bridge on the highway. SR&nbsp;1 then passes through [[Little River, California|Little River]] and [[Van Damme State Park]], crosses [[Big River (California)|Big River]] and passes through [[Mendocino Headlands State Park]] and the Victorian community of [[Mendocino, California|Mendocino]]. Continuing north, SR&nbsp;1 crosses [[Russian Gulch State Park]] on the [[Frederick W. Panhorst Bridge]], and passes through the town of [[Caspar, California|Caspar]]. It passes through a [[roundabout]] just south of the intersection with the western terminus of [[California State Route 20|SR&nbsp;20]],<ref>{{cite news |title = Fort Bragg's $4.4 million roundabout |work = [[The Press Democrat]] |url = http://roadwarrior.blogs.pressdemocrat.com/12572/fort-braggs-4-4-million-roundabout/ |date = May 18, 2011 |access-date = July 8, 2011 |archive-url = https://web.archive.org/web/20110824124454/http://roadwarrior.blogs.pressdemocrat.com/12572/fort-braggs-4-4-million-roundabout/ |archive-date = August 24, 2011 |url-status = dead }}</ref><ref>{{cite web |url = http://www.dot.ca.gov/dist1/d1projects/simpson_lane/ |title = Simpson Lane Intersection |author = California Department of Transportation  |publisher = California Department of Transportation |access-date = July 7, 2011 |url-status = dead |archive-url = https://web.archive.org/web/20100823145427/http://dot.ca.gov/dist1/d1projects/simpson_lane/ |archive-date = August 23, 2010}}</ref> where it widens to two lanes, then bridges the [[Noyo River]] at [[Noyo, California|Noyo]], becomes Main Street of [[Fort Bragg, California|Fort Bragg]], and crosses the [[California Western Railroad]].<ref name="CA2010map" /><ref name="google" />

North of Fort Bragg as a two-lane highway again, SR&nbsp;1 passes [[MacKerricher State Park]] and the towns of [[Cleone, California|Cleone]] and [[Inglenook, California|Inglenook]] before crossing [[Ten Mile River (California)|Ten Mile River]]. After passing [[Westport-Union Landing State Beach]], the road goes through a series of redwood-forested switchbacks before reaching [[Rockport, California|Rockport]]. North of 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&nbsp;101 just outside [[Leggett, California|Leggett]].<ref name="CA2010map">{{cite map |publisher = California Travel & Tourism Commission |year = 2010 |title = Official State Map |author = California Travel Media |scale = Scale not given |section = E2–M7, N1–X11, AA3–HH8}}</ref><ref name="google">{{google maps |url= https://www.google.com/maps/dir/33.4654009,-117.6715683/Leggett,+CA/@36.5639519,-121.3861828,1051847m/data=!3m1!1e3!4m66!4m65!1m55!3m4!1m2!1d-119.3992678!2d34.3314612!3s0x80e9a9c6e4d4512d:0x8e854ab2970d526!3m4!1m2!1d-119.743221!2d34.4318117!3s0x80e9151fd0ff67a5:0xe5a3d118c7b971a!3m4!1m2!1d-120.1939774!2d34.4726531!3s0x80eeb2ec455ddb9b:0xcf4c63fac8e6343d!3m4!1m2!1d-120.4575528!2d34.6653912!3s0x80ec194a95a80c2b:0xf2cb30ddd9c003fa!3m4!1m2!1d-121.6985489!2d36.1770126!3s0x808d810b2e374b2b:0xdd37d56561c7b227!3m4!1m2!1d-122.5118093!2d37.5971495!3s0x808f7a98dd88438b:0x89543020290f0a38!3m4!1m2!1d-122.4904785!2d37.6574322!3s0x808f7b9f3efa1ff9:0xecafa6b2bea3f3bd!3m4!1m2!1d-122.4712362!2d37.7112309!3s0x808f7c49b3a0c873:0x73f16c9814efde48!3m4!1m2!1d-122.5873801!2d37.8668995!3s0x80858e2c016a57ed:0x81e09fbaf6791ef5!3m4!1m2!1d-122.8022825!2d38.0746818!3s0x8085c67c33de0d3b:0x4019e880ed00209a!3m4!1m2!1d-123.6854295!2d39.0428901!3s0x8081049556d90c41:0x4059ea7363d49184!1m5!1m1!1s0x54d4cc1fffa328f9:0x28dffafca0e1592e!2m2!1d-123.7148275!2d39.8654841!2m1!1b1!3e0 |title= Overview Map of State Route 1 |access-date= January 24, 2015}}</ref>

==History==
SR&nbsp;1 has become famous worldwide,<ref name=pogash/> but the highway was signed as several other routes prior to 1964. When the road was first envisioned in the World War I era, California highways were referred to by either a highway name or 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 SR&nbsp;1 designation was first assigned in 1939. Various portions of SR&nbsp;1 have been posted and referred to by various names and numbers over the years. State construction of what became SR&nbsp;1 started after the state's third highway [[Bond (finance)|bond issue]] passed before 1910.

Eager for a direct coastal route between [[Ventura, California|Ventura]] and [[Santa Barbara, California|Santa Barbara]], civic boosters used locally raised funds to begin building the [[Rincon Sea Level Road]] in 1911. The route between the [[Ventura River]] and [[Carpinteria, California|Carpinteria]] had been an unimproved route along small alluvial fan beaches that skirted coastal bluff rock outcroppings at low tide.<ref>{{cite magazine |last = Yates |first = Morgan P. |date = September 2009 |title = Drive the Planks |url = http://ww1.calif.aaa.com/westways/archives/2009-09/Pages/off-ramp.asp |magazine = Westways |publisher = [[Automobile Club of Southern California]] |location = Santa Ana, California |url-access=subscription|access-date=December 18, 2014}}{{Dead link|date=November 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> Construction of the [[Southern Pacific Transportation Company|Southern Pacific]] [[Coast Line (UP)|Coast Line railroad]] had created a road flanked by [[riprap]] along this area.

One of the most difficult routes to build was along the [[Big Sur]] coast.

Federal funds were appropriated and in 1921 voters approved additional state funds. [[San Quentin State Prison]] set up three temporary prison camps to provide unskilled [[Unfree labour|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 Canyon|Anderson Creek]]. Inmates were paid 35 cents per day and had their prison sentences reduced in return. The route necessitated construction of 33 bridges, the largest of which was the [[Bixby Bridge]]. Six more concrete arch bridges were built between Point Sur and Carmel.<ref name="cambria">{{cite web |title = The Building of Highway One |url = http://cambriahistoricalsociety.com/history_highway1.html |work = Historical Moments |publisher = Cambria Historical Society |access-date = December 16, 2011 |archive-url = https://web.archive.org/web/20120123035538/http://cambriahistoricalsociety.com/history_highway1.html |archive-date = January 23, 2012 |url-status = dead }}</ref>

Route 60, from [[Oxnard, California|Oxnard]] via the coast to [[San Juan Capistrano, California|San Juan Capistrano]], was extended from Oxnard to [[El Rio, California|El Rio]] (midway to Ventura, now the site of the Oxnard Boulevard interchange with [[US&nbsp;101 (CA)|US&nbsp;101]]), in 1925. At [[Point Mugu, California|Point Mugu]], a path for the highway was cut through the mountains using surplus World War I explosives, thus creating Mugu Rock.<ref name="Modern Marvels">{{cite episode |title = Pacific Coast Highway |series = [[Modern Marvels]] |credits = [[Jupiter Entertainment]] |network = [[History (U.S. TV channel)|The History Channel]] |airdate = 2004}}</ref> The 1921 legislation, in theory, made Route 60 a continuous coastal loop, with both ends at what became [[US&nbsp;101 (CA)|US&nbsp;101]] in Oxnard and at Capistrano Beach (since 1964 the southern terminus of SR&nbsp;1 at [[Interstate 5]] in Orange County).<ref>{{Cite California statute|year=1925|ch=309|p=508}}</ref> Route 56 was extended further south from Cambria to connect to present-day US&nbsp;101 in [[San Luis Obispo, California|San Luis Obispo]] in 1931.<ref>{{Cite California statute|year=1931|ch=82|p=103}}</ref>

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, California|Pismo Beach]] on US&nbsp;101 (Route 2) and heading south through [[Guadalupe, California|Guadalupe]] and [[Lompoc, California|Lompoc]] to rejoin US&nbsp;101 at a junction called Los Cruces (sic), just north of Gaviota Pass. (A short piece near [[Orcutt, California|Orcutt]] and Los Alamos had been part of Route 2, which originally followed present [[California State Route 135|SR&nbsp;135]] from Los Alamos to Santa Maria.) To the north, Route 56 was continued along the coast from Carmel through [[Santa Cruz, California|Santa Cruz]] to [[San Francisco]]. Several discontinuous pieces were added north of San Francisco, one from Route 1 (US&nbsp;101) north of the [[Golden Gate]] to the county line near [[Valley Ford, California|Valley Ford]], another from the [[Russian River (California)|Russian River]] near [[Jenner, California|Jenner]] (where the new [[Legislative Route 104 (California pre-1964)|Route 104]] ended) to [[Westport, California|Westport]], and a third from [[Ferndale, California|Ferndale]] to Route 1 near [[Fernbridge, California|Fernbridge]].

The section of SR&nbsp;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, California|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. SR&nbsp;1 also used to run along the coast between Pacifica and Daly City, but this segment was damaged and rendered unusable after [[1957 San Francisco earthquake|a 5.3 magnitude earthquake]] on March 22, 1957.

Route 56 along Big Sur was incorporated into the state highway system and re-designated as SR&nbsp;1 in 1939. The section of road along the Big Sur Coast was declared the first State Scenic Highway in 1965, and in 1966 the first lady, [[Lady Bird Johnson]], led the official designation ceremony at [[Bixby Bridge]].<ref name="pavlik">{{cite web |last = Pavlik |first = Robert C. |title = Historical Overview of the Carmel to San Simeon Highway |url = http://www.dot.ca.gov/dist05/projects/bigsur/pdfs/chmp_hist.pdf |work = Historic Resource Evaluation Report on the Rock Retaining Walls, Parapets, Culvert Headwalls and Drinking Fountains along the Carmel to San Simeon Highway |publisher = California Department of Transportation |access-date = December 17, 2011 |date = November 1996 |archive-url = https://web.archive.org/web/20161226175643/http://www.dot.ca.gov/dist05/projects/bigsur/pdfs/chmp_hist.pdf |archive-date = December 26, 2016 |url-status = live }}</ref> The route was designated as an All American Road by the US Government.<ref name="cambria" />

SR&nbsp;1 signs first went up after California decided to number its highways, in 1934. The section for [[Humboldt County, California|Humboldt]], [[Mendocino County, California|Mendocino]], [[Sonoma County, California|Sonoma]], [[Marin County, California|Marin]], [[San Francisco]], [[San Mateo County, California|San Mateo]], [[Santa Cruz County, California|Santa Cruz]], [[Monterey County, California|Monterey]], [[San Luis Obispo County, California|San Luis Obispo]] and [[Santa Barbara County, California|Santa Barbara]] counties was posted as SR&nbsp;1, that section of the road known Route 56 (Las Cruces to Fernbridge). For [[Ventura County, California|Ventura]], [[Los Angeles County, California|Los Angeles]] and [[Orange County, California|Orange]] counties, Route 60 (San Juan Capistrano to the Oxnard area) became SR&nbsp;3, and a few SR&nbsp;3 signs were actually posted.<ref>{{cite journal|first=T.H.|last=Dennis|date=August 1934|url=https://archive.org/details/californiahighwa193436calirich/page/n275/mode/2up/|title=State Routes Will Be Numbered and Marked with Distinctive Bear Signs|journal=[[California Highways and Public Works]]|volume=11|issue=8|pages=20–21, 32|issn=0008-1159|via=Internet Archive}}</ref> The SR&nbsp;3 signs were replaced by US&nbsp;101 Alt. shields by 1936, as the road was built out; this change also allowed the extension of [[U.S. Route 66 in California|US&nbsp;66]] to end at another U.S. Route, in Santa Monica.<ref>{{cite map |author = Automobile Club of Southern California |author-link = Automobile Club of Southern California |publisher = Automobile Club of Southern California |url = http://digitallibrary.usc.edu/cdm/search/searchterm/acsc-m20/order/nosort |title = Automobile Route Along the Pacific Coast from Seal Beach to Santa Monica |year = 1936 |access-date = January 27, 2013 |archive-url = https://archive.today/20130217110556/http://digitallibrary.usc.edu/cdm/search/searchterm/acsc-m20/order/nosort |archive-date = February 17, 2013 |url-status = dead }}</ref>

The gaps of non-state highway along the northern coast were finally filled in by the Legislature in 1951, though the [[Department of Public Works (California)|State Department of Public Works]] was not required to maintain the newly added portions immediately. A connection from near Rockport to Legislative Route&nbsp;1 (signed US&nbsp;101) at [[Leggett, California|Leggett]] was also added to the Legislative Route 56 definition,<ref>{{Cite California statute|year=1951|ch=1588|p=3585|quote=Route 56 is from ... to Route 1 near Fernbridge via the coast route through Jenner, Westport and Ferndale, including lateral connection with Route 1 near Leggett Valley}}</ref> as the existing county road north from Rockport to Ferndale had not yet been [[paved road|paved]].<ref>{{cite map |author = H.M.

The state Legislature in 1963 tossed out the old conflicting Legislative Route Numbers ([[1964 renumbering (California)|1964 renumbering]]), got rid of some famous old U.S. routes, and renumbered many state highways. It abolished US&nbsp;101A in Los Angeles, Orange and Ventura counties and renumbered it as SR&nbsp;1. The Rockport to Leggett connection then became State Route 208.<!--was it signed as such or as SR&nbsp;1?--><ref>{{Cite California statute|year=1963|ch=385|p=1171, 1186}}</ref> The cover of "California Highways" magazine in fall 1964 shows state engineers posting the new shield at Point Mugu.<ref>{{citation |title = California Highways |date = September 1964}}{{Full citation needed | date= December 2014}}</ref> The same year, the Legislature by state law named SR&nbsp;1 "Pacific Coast Highway" in Orange, Los Angeles and Ventura counties, "Cabrillo Highway" from Santa Barbara north to San Francisco, and "Shoreline Highway" from Marin County to its northern terminus. Many cities, however, did not change the name of city streets that are part of SR&nbsp;1, such as Lincoln and Sepulveda boulevards in Los Angeles, Santa Monica and El Segundo; and Junipero Serra and Park Presidio boulevards in San Francisco. Several other cities and communities like Newport Beach, Laguna Beach and Bodega Bay merely named their respective city streets as "Coast Highway".

===Modern alignments===

[[File:End of CA 1 Leggett.JPG|thumb|left|Signs marking the northern terminus of SR&nbsp;1 near Leggett; the route was originally proposed to run further north, but these plans were abandoned to avoid the steep and unstable highlands of the Lost Coast region.]]

The freeway portion of SR&nbsp;1 from Highway 68 in Monterey to Munras Avenue opened in 1956–1960. 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 SR&nbsp;1 alignment through [[Fort Ord]] in 1973. North of Fort Ord, SR&nbsp;1 now veers to the left of the original alignment and bypasses Marina to the west. This segment including the interchange with [[California State Route 156|SR&nbsp;156]] and the short, 2-lane Castroville Bypass opened in 1976. Originally SR&nbsp;1 followed the SR&nbsp;156 alignment to the [[California State Route 183|SR&nbsp;183]] intersection in Castroville, then turned northwest, following the present-day SR&nbsp;183 through Castroville before rejoining its existing alignment at the northern terminus of the Castroville Bypass.

Plans to upgrade SR&nbsp;1 to a freeway from its southern terminus all the way to Oxnard, including building an offshore causeway from the [[Santa Monica Pier]] to [[Topanga Canyon Boulevard]] south of Malibu, were ultimately killed by 1971 due to local opposition.<ref>{{cite web |url = http://www.kcet.org/updaily/socal_focus/history/la-as-subject/from-the-roosevelt-highway-to-the-one-a-brief-history-of-pacific-coast-highway.html |title = From Roosevelt Highway to the 1: A Brief History of Pacific Coast Highway |first = Nathan |last = Masters |publisher = [[KCET]] |date = May 2, 2012 |access-date = November 17, 2013 |archive-url = https://web.archive.org/web/20131116095333/http://www.kcet.org/updaily/socal_focus/history/la-as-subject/from-the-roosevelt-highway-to-the-one-a-brief-history-of-pacific-coast-highway.html |archive-date = November 16, 2013 |url-status = dead }}</ref> In 1980, another section was added northwest of [[Ventura, California|Ventura]] near [[Emma Wood State Beach]], when several miles of the old two-lane alignment of [[U.S. Route 101 in California|U.S. Route 101]] were posted as SR&nbsp;1 where the freeway had bypassed it in about 1960. Then in 1988, the segment from Purisima Road in Lompoc to SR&nbsp;135 was re-routed from Harris Grade Road to the former County Route S20 so it could directly serve [[Vandenberg Space Force Base#Vandenberg Air Force Base|Vandenberg Air Force Base]].

Construction to bridge the gap in the [[Lost Coast]] region between Rockport and Ferndale was eventually abandoned. The steepness and related geotechnical challenges of the coastal mountains made this stretch of coastline too costly for highway builders to establish routes through the area.<ref name="King Range">{{cite web |title = King Range National Conservation Area |url = http://www.blm.gov/ca/st/en/fo/arcata/kingrange/index.html |publisher = [[Bureau of Land Management]] |access-date = June 25, 2012 |archive-url = https://web.archive.org/web/20120702104826/http://www.blm.gov/ca/st/en/fo/arcata/kingrange/index.html |archive-date = July 2, 2012 |url-status = dead }}</ref> In 1984, SR&nbsp;1 was then re-routed to replace State Highway 208, connecting Rockport and Leggett, while the segment between Ferndale and Fernbridge was renumbered as [[California State Route 211|State Highway 211]].<ref>{{Cite California statute|year=1984|ch=409|p=1769, 1774}}</ref> Most of the coastline in the area is now part of [[Sinkyone Wilderness State Park]] and the [[King Range National Conservation Area]].

The roadway along [[Devil's Slide (California)|Devil's Slide]], south of [[Pacifica, California|Pacifica]], became the site of frequent deadly crashes and roadway-closing [[landslide]]s. Beginning in 1958, [[California Department of Transportation|Caltrans]] supported a plan to construct an inland bypass over [[Montara Mountain]] as an alternate route, but was eventually opposed by community and environmental groups who supported a tunnel instead. After decades of legal disputes, the [[Federal Highway Administration]] ordered Caltrans in 1995 to re-evaluate the proposed tunnel. Then on November 5, 1996, San Mateo County voters approved Measure T to change the county's official preference from the bypass to the tunnel. Ground eventually broke in 2005, and the [[Tom Lantos Tunnels]] opened in April 2013.

In 2014, two-way traffic was restored along the original PCH segment from Copper Lantern to Blue Lantern streets in the Dana Point city center after 25 years of one-way operation.<ref>{{cite news |url = http://www.ocregister.com/articles/coast-635311-pacific-highway.html |title = Dana Point sees two-way traffic flow on Pacific Coast Highway |last = Zhou |first = Kelly |newspaper = [[Orange County Register]] |date = September 16, 2014 |access-date = January 1, 2015 |archive-url = https://web.archive.org/web/20160304112642/http://www.ocregister.com/articles/coast-635311-pacific-highway.html |archive-date = March 4, 2016 |url-status = live }}</ref> During that period, only northbound traffic had flowed along this section of PCH while southbound traffic had been diverted onto the parallel Del Prado Avenue.

SR&nbsp;1 has never been planned to extend south into [[San Diego]], or north into [[Crescent City, California|Crescent City]], where I-5 (which replaced the US&nbsp;101 designation and signage between Los Angeles and San Diego) and US&nbsp;101 serve as the coastal highways in those areas, respectively.

===Landslides===
Frequent [[California landslides|landslides]] and erosion along the coast have caused portions of SR&nbsp;1 to either be closed for long periods of time, or be re-routed entirely. Some of these include:

* A segment along the coast between Pacifica and Daly City in what is now [[Thornton Beach, California|Thornton Beach]] was damaged and rendered unusable after a 5.3 magnitude earthquake on March 22, 1957. SR&nbsp;1 was then eventually re-routed to turn inland to join Interstate 280.
* The Piedras Blancas Realignment Project plans to re-route the road up to {{convert|475|ft|m}} further inland to avoid the expected coastal erosion from the [[Piedras Blancas Light Station]] to the Arroyo de la Cruz Bridge in San Luis Obispo County.<ref>{{cite web|author=District 5|url=http://www.dot.ca.gov/dist05/projects/slo1_piedras/index.htm |title=Piedras Blancas Realignment Project|publisher=California Department of Transportation|access-date = November 29, 2011|archive-url=https://web.archive.org/web/20111221070337/http://www.dot.ca.gov/dist05/projects/slo1_piedras/index.htm|archive-date=December 21, 2011|url-status=live}}</ref>
*Big Rock Mesa landslide in September 1983 in [[Malibu, California|Malibu]] was one of the worst in state history. A total of 250 homes collapsed, cracked or slid off their foundation with 30 homes being condemned.
