5244-453: The San Joaquin Valley via the Mojave Desert and Tehachapi Pass . In 1910, Beale's Cut was bypassed by the Newhall Tunnel. Constructed by Los Angeles County, it was too narrow for two trucks to pass each other inside. As a result, in 1939, the tunnel was completely removed (or " daylighted ") when the road was widened to four lanes. Additionally, by 1930, a bypass road was constructed to avoid Newhall Pass via Weldon and Gavin canyons, which

5358-409: The Sproul Brothers in Oregon. They recalled the fertile land and huge sycamore trees they saw during an earlier visit to the Southern California area.

5928-431: The West Side Freeway and the Golden State Highway. The third phase, completed in 1979, extended the freeway to Sacramento and connected it to the northern I-5. When the second phase of the freeway opened in 1972, it was a long and lonely route with no businesses alongside. Services were not easily available as the nearest towns were miles away and generally out of sight. It was common for cars to run out of fuel. Over time

6042-404: The area became increasingly residential. In February 1958, two military aircraft, a Douglas C-118 A military transport and a U.S. Navy P2V -5F Neptune patrol bomber, collided over Norwalk at night.

I-5 then enters Commerce , passing the Citadel Outlets shopping center, and intersects I-710 before entering

7296-433: The county line. At an OCTA board meeting in August 2024, it was discussed that preliminary engineering is ongoing and will be complete next year. However, a timeline for actual construction was not provided. This extension would give way for I-5 to have carpool lanes for its entire length in Orange County, plus the newly widened section in Los Angeles County, for a total of 50 miles. OCTA and Caltrans are expected to work with

7410-451: The driving wheels, except 4WD vehicles with snow tires. Additionally, during the winter season, trucks are required to carry chains whether or not controls are in force.

7752-511: The founder of Norwalk, Gilbert Sproul. He and his family lived there while he founded Norwalk. His descendants lived in the house continually until 1962 when it was donated to the city. Today it houses the Gilbert Sproul Museum which covers Norwalk history through artifacts, photos, documents and other interpretive elements. Norwalk is located at 33°54′25″N 118°5′0″W  /  33.90694°N 118.08333°W  / 33.90694; -118.08333 (33.906914, -118.083398). According to

7866-443: The freeway from the Sacramento River. However, the system slowly clogged up over the years with sand and silt buildup Major repair work of the Boat Section began on May 30, 2008. The construction was to take 40 days to complete, requiring complete northbound and southbound closures on an alternating schedule. In 1992, Caltrans finished upgrading the final 13 mile segment north of Lakehead . I-5 through north San Diego County

7980-475: The highway, forming an infrastructure corridor along with the California Aqueduct . After the Grapevine, I-5 crosses the California Aqueduct. This is first time out of 5 times that I-5 crosses the aqueduct. North of the Grapevine, I-5 intersects SR 166 , SR 119 and SR 43 before meeting SR 58 , a highway that continues east to Bakersfield, near the town of Buttonwillow . I-5 then intersects SR 46 before entering Kings County . From

8094-536: The intersection of Routes 166 (Indiana Street, soon moved to Downey Road) and 2 (US 101 along Whittier Boulevard), and following Routes 166 and 174 to Route 2 (US 101) in Anaheim. The connection between Routes 166 and 174 was made via Route 168 (Rosemead Boulevard, then and now SR 19 ). This resulted in SR 10 being truncated further, to the intersection of Firestone and Rosemead Boulevards, though SR 26 continued to extend east on Routes 166 and 171 to Buena Park. A freeway connecting downtown Los Angeles with Orange County

8208-677: The large unincorporated community of East Los Angeles and later the city proper of Los Angeles . When the freeway reaches the East Los Angeles Interchange 1 mi (1.6 km) east of downtown Los Angeles, I-5 becomes the Golden State Freeway as US 101 takes over the Santa Ana Freeway designation. At this interchange, I-10 , SR 60 , and US 101 intersect; I-10 continues north on I-5 for about 2 mi (3.2 km) before continuing east towards San Bernardino and points farther east. On

8322-616: The last three miles from SR 78 to Oceanside Harbor Drive, however, there is a lack of funding for them, and there are no plans to set aside funding from the state to construct them. In Orange County, the HOV lane opened in the mid-1990s between SR 1 and SR 91, following the widening of the freeway between SR 55 and SR 91, between SR 91 and Artesia Boulevard in 2010, and between SR 1 and Avenida Pico in 2018. Multiple carpool flyovers were constructed during this time to connect motorists from one freeway's carpool lanes to

8436-555: The latter. I-5 then intersects SR 55 and enters Santa Ana , the county seat of Orange County. Towards the northern side of Santa Ana, I-5 intersects both SR 57 and SR 22 in what is known as the Orange Crush interchange . Following this, I-5 briefly enters the city of Orange and then traverses Anaheim , passing along the north side of Disneyland . I-5 then intersects SR 91 , passes through Buena Park and crosses into Los Angeles County . After crossing

8550-556: The longest for a north-south Interstate) with a single designation within a single state after I-10 in Texas . It is the more important and most-used of the two major north–south routes on the Pacific Coast, the other being U.S. Route 101 (US 101), which is primarily coastal. I-5 links the major California cities of San Diego, Santa Ana , Los Angeles , Stockton , Sacramento , and Redding . The San Francisco Bay Area

8664-410: The money in 1882. Norwalk's prosperity was evident in the 1890s with the construction of a number of fine homes that were located in the middle of orchards, farms and dairies. Headstones for these families can be found at Little Lake Cemetery, which was founded in 1843 on the border between Norwalk and Santa Fe Springs at Lakeland Road. At the turn of the 19th century, Norwalk had become established as

8778-597: The most congested freeways in Southern California. The infamously busy intersection of the Santa Ana, Garden Grove , and Orange freeways in southwestern Orange is nicknamed the Orange Crush . The freeway is officially defined as Routes 101 and 5 from Route 110 ( Four Level Interchange ) to Route 405. The Santa Ana Freeway is a bypass of the original state highway from Los Angeles to Santa Ana, which passed through Whittier and mostly became SR 72 in

8892-681: The name was chosen in a public contest in 1927, but was never officially adopted. Since the construction of I-5, it has taken over the term "Golden State Freeway" from 99 south of the latter's southern terminus in Kern County. The Golden State Freeway was proposed by the California Highway Commission in 1953. The proposal drew strong criticism from East Los Angeles residents as it would dissect and eliminate large residential and commercial areas of Boyle Heights and Hollenbeck Heights. The proposal also seemed to indicate

9006-406: The new Route 172 (now SR 60 ), at the corner of Indiana and Third Streets, and headed south on Indiana Street and east and southeast on Mines Avenue ( Olympic Boulevard ) and Anaheim-Telegraph Road (now Telegraph Road) to Route 171 (now SR 39 ) at the intersection with Los Nietos Road near Santa Fe Springs . Route 174 began at Route 60 (then signed Alternate U. S. 101 now SR 1 ) in what now

9120-520: The newspaper The Eastside Sun wrote the freeway led to the "eradication, obliteration, razing, moving, ripping asunder, demolishing of Eastside homes." A widowed Edendale resident, Lomie Puckett, resisted the condemnation of one of her rental properties in August 1958 by using a rifle to threaten state workers and police. After a five-day standoff with police, the home was seized and later demolished. The section between Orange County and Los Angeles

9234-536: The next (see Exit List for a list of them). In 2013, ground broke on a major expansion of the freeway through La Mirada and Norwalk in neighboring Los Angeles County to the I-605 interchange, which included a carpool lane to Florence Avenue. The carpool lane fully opened in 2023. Currently, in San Clemente, there are studies to extend the carpool lanes from their current terminus at Avenida Pico to Cristianitos Road at

9348-701: The north side of downtown, the Golden State Freeway follows the Los Angeles River , intersects SR 110 and SR 2 and passes along the eastern side of Griffith Park . The route continues through the San Fernando Valley , intersecting the Ventura Freeway (SR 134). It briefly enters the city of Glendale and then Burbank , passing near Burbank Airport before reentering the Los Angeles city limits and intersecting

9462-737: The northern end of the Hollywood Freeway (SR 170). Near the city of San Fernando , I-5 intersects SR 118 . Following this, I-5 intersects three routes in succession: the northern end of I-405, the western end of I-210 , and the southern end of SR 14 at the Newhall Pass interchange . It then crosses the Newhall Pass through the Santa Susana Mountains into the Santa Clarita Valley . I-5's carpool lanes also have direct connectors with

9576-408: The old Ridge Route, but was not enough to satisfy demand, and a conversion to a four-lane expressway was needed. The outbreak of World War II delayed this until 1948 and the fourth lane was completed in 1952. However, just three years later, plans were begun for converting the four-lane expressway to a six-lane freeway. The last major alteration to the Ridge Route began in the early 1960s. By then,

9690-635: The opportunity to visit the "country" from across the nation. The families referred to as the "first families" of Norwalk (including the Sprouls, the Dewitts, the Settles, and the Orrs) settled in the area in the years before 1900. D.D. Johnston pioneered the first school system in Norwalk in 1880. Johnston was also responsible for the first real industry in town, a cheese factory, by furnishing Tom Lumbard with

9804-521: The original overpasses were retained, and some undercrossings also have no right hand shoulder as a result. A third phase saw the widening between SR 134 and Buena Vista Street, and the carpool lane opened in 2022. This phase gave room for the replacement of the Burbank Boulevard bridge, and the opening of a new interchange at Empire Avenue, which replaced the Scott Road and Lincoln Street interchanges. The Empire Avenue interchange opened in 2019 and

9918-457: The plan for a six-lane freeway had expanded to eight lanes. This construction project made the most changes to the route. Many of the curves that followed the mountainside were cut through. To climb the mountain on the south side of Castaic more easily, traffic lanes were reversed (southbound lanes to the east and northbound lanes to the west). To prevent head-on collisions , the two ends of the route were separated on two different mountainsides, and

10032-657: The population) lived in households, 315 (0.3%) lived in non-institutionalized group quarters, and 1,300 (1.2%) were institutionalized. There were 27,130 households, out of which 13,678 (50.4%) had children under the age of 18 living in them, 15,190 (56.0%) were opposite-sex married couples living together, 5,045 (18.6%) had a female householder with no husband present, 2,348 (8.7%) had a male householder with no wife present. There were 1,712 (6.3%) unmarried opposite-sex partnerships , and 178 (0.7%) same-sex married couples or partnerships . 3,417 households (12.6%) were made up of individuals, and 1,631 (6.0%) had someone living alone who

10146-565: The population) lived in owner-occupied housing units and 33,754 people (32.0%) lived in rental housing units. During 2009–2013, Norwalk had a median household income of $ 60,770, with 12.9% of the population living below the federal poverty line. As of the census of 2000, there were 103,298 people, 26,887 households, and 22,531 families residing in the city. The population density was 10,667.6 inhabitants per square mile (4,118.8/km ). There were 27,554 housing units at an average density of 2,845.5 per square mile (1,098.7/km ). The racial makeup of

10260-431: The residents of San Clemente during the process, as several bridges may have to be replaced with wider ones, and buildings may have to be demolished for the widening. North of downtown Los Angeles, the freeway is currently going widening, which includes the addition of HOV lanes in four phases. The first phase was the opening of a carpool lane between carpool lane between SR 170 and SR 14 in 2011. A flyover between

10374-561: The rest of the San Francisco Bay Area. Original plans also called for a loop Interstate with a directional suffix, I-5W. This route now roughly corresponds to I-580 from I-5 south of Tracy to Oakland, I-80 from Oakland to Vacaville, and I-505 from Vacaville to I-5 near Dunnigan. I-5W and most of the other Interstates around the country with directional suffixes were eventually renumbered or eliminated, except I-35E and I-35W in Texas and Minnesota. Nevertheless, San Francisco

Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines;

10602-466: The second-largest median in California after I-8 's In‑Ko‑Pah grade. In Siskiyou County , I-5 passes through Dunsmuir before intersecting SR 89 near Lake Siskiyou and entering the city of Mount Shasta . North of here, US 97 intersects I-5 in Weed , providing access to Klamath Falls, Oregon . The Interstate then continues to Yreka , intersecting SR 3 and SR 96 before crossing

10716-632: The section of highway between Castaic and Grapevine, through the Tejon Pass. The highway had its origins in the early 1910s, when a route was needed to connect Los Angeles to the Central Valley. Some believed that the only option was the route through the Mojave Desert and the Tehachapi Mountains, but a new route was discovered through the Tejon Pass. This route became known as the Ridge Route and saw almost constant planning, construction, and improvement from 1914 to 1970. The first road

10830-487: The section through Piru Canyon was moved to an entirely new alignment to make room for Pyramid Lake. The project was completed by 1970 and brought the Ridge Route to its current alignment. When the Interstate Highway System was created in 1956, there was discussion about which way to route the interstate through the San Joaquin Valley (Central Valley). Two proposals were considered. One was to convert

10944-516: The spot of the accident, today a mini-mall at the corner of Firestone Boulevard and Pioneer Boulevard. Built in 1891 by the D.D. Johnston family, the Hargitt House was built in the architectural style of Victorian Eastlake . The Hargitt House Museum, located at 12426 Mapledale, was donated to the people of Norwalk by Charles ("Chun") and Ida Hargitt. The Sproul House is a Stick Style -influenced, Victorian farm house built in 1870 by

11058-458: The spur into the Bay Area) connecting I-80 out of Vacaville to near Dunnigan, previously known as I-5W , was renamed I-505 . Interstate 580 running between I-5 and I-80 was also once designated 5W; what is now I-5 (the stretch that runs through Sacramento) had been originally designated I-5E . The term "Golden State Highway" was the popular name for US 99 through the length of California;

11172-719: The start and end postmiles in each county are given in the county column. Golden State Freeway Interstate 5 ( I-5 ) is a major north–south route of the Interstate Highway System in the United States, running largely parallel to the Pacific Coast between the Mexican border and the Canadian border . The segment of I-5 in California runs across the length of the state from

11286-739: The station also provided contracted police services to Santa Fe Springs , but those services ended when the city entered into a contract with the Whittier Police Department. The station is staffed with 206 sworn personnel. Fire protection in Norwalk is provided by the Los Angeles County Fire Department with ambulance transport by Care Ambulance Service . Norwalk is the home of the Los Angeles County Registrar/Recorder. The Los Angeles County Registrar's Office

11400-567: The top employers in the city are: Although Norwalk is credited with being the home to Cerritos College , only the east half of the campus is actually in Norwalk, the west half is in Cerritos. Founded in 1955, Cerritos College is a public community college serving an area of 52 square miles (130 km ) of southeastern Los Angeles county. The college offers degrees and certificates in 87 areas of study in nine divisions. Over 1,200 students complete their course of studies each year. Most of Norwalk

11514-581: The towns of Saugus and Newhall , and then crossed Newhall Pass (current route of SR 14, the Antelope Valley Freeway). In 1862, Beale's Cut was made in the construction of a toll wagon road. The 15 ft wide (4.6 m) by 60 ft deep (18 m) "slot" was dug with picks and shovels. That road would become part of the Midway Route. At the turn of the century, it was the most direct automobile route between Los Angeles and

11628-658: The western end of SR 905 , a route that connects with the Otay Mesa border crossing . I-5 then continues northward and joins the southern end of SR 75 , a highway connecting to Coronado via the Silver Strand . I-5 then enters Chula Vista , briefly leaving the San Diego city limits. It continues along the east side of San Diego Bay where it intersects with SR 54 and enters National City . From there, I-5 veers around Naval Base San Diego and reenters

11742-592: The works, but there are no near plans to construct it. The same plan includes a southerly extension of the HOV lanes to the San Bernardino Split interchange, but there are no near plans to construct that as well. Widening that segment of the freeway will require several overpass demolitions, as well a major widening through the area, as the freeway is too small to handle the widening. The widening would also result in hundreds of homes and commercial buildings to be demolished. Norwalk, CA Norwalk

The median age

12198-400: Was completed in 1915. It was a slow, winding, two-lane road through the mountains with a speed limit of 15 mph (24 km/h) in some places. However, the need for improvements was realized soon after it was completed. The road was paved after World War I , and several blind turns were opened up ("daylighted"). Even with these improvements in the 1920s, it became clear that a new route

12312-402: Was flooded with 15 ft (4.6 m) of water. Caltrans began constructing this section during the 1960s and 1970s. The freeway was engineered below grade so it would be out of the view of offices and shops in downtown Sacramento. To achieve this, the site was excavated and the seeping water was pumped from the area. An intricate drainage system, water pump and retaining wall are used to protect

12426-401: Was marked as part of Sign Route 6 (which continued along Route 171 to Buena Park ), and the entire length of Route 174 became Sign Route 10 . (SR 6 was renumbered to SR 26 in 1937, when US 6 entered California; SR 10 was soon truncated to Anaheim Boulevard, as US 101 had moved from Route 2 to the shorter Route 174 in Santa Ana.) A U.S. Route 101 Bypass was created by 1941, beginning at

12540-442: Was needed to keep up with increasing demand. In 1927, plans were drawn up for a "Ridge Route Alternate", named as it was planned as an addition to the existing Ridge Route and not as a replacement. It opened in 1933 as a three-lane highway through the mountains. The middle or "suicide lane" was used as an overtaking lane for cars in both directions. This route was a great improvement, faster and 9.7 mi (15.6 km) shorter than

12654-483: Was originally designed to have three lanes in each direction. Due to high traffic demand, the freeway started undergoing major extensions and widening in the early 1990s in Orange County. Work from SR 91 north through the Los Angeles–Orange County line was completed in 2010. Reconstruction between the county line and Interstate 605 began in 2013 and was completed by early 2023. The original route went through

12768-477: Was originally signed as US 99. From 1964 to 1968, the I-105 designation was used on a stretch of road linking I-5/I-10, US 101, and SR 10 (former I-110) north of downtown Los Angeles, now known as the East Los Angeles Interchange. In 1968, this I-105 was decommissioned , and that portion of the Santa Ana Freeway was folded into US 101. Except where prefixed with a letter, postmiles were measured on

12882-696: Was planned by 1939, and was included in A Transit Program for the Los Angeles Metropolitan Area , published that year by the Metropolitan Transportation Engineering Board. To allow for its construction by the state, the definition of Route 166 was modified in 1941, changing the southeast end to Route 174 near Norwalk ; at the same time, the northernmost piece was changed from Indiana Street to Downey Road. The entire Santa Ana Freeway began construction in 1947 and completed in 1956. Originally it

12996-604: Was signed as US 101 before the segment of 101 between the East Los Angeles Interchange and the United States–Mexico border in San Ysidro, California was decommissioned in favor of Interstate 5 . It was approved as a chargeable interstate in 1961. The Santa Ana Freeway and also portions of San Diego Freeway (before the freeway was built) south of El Toro Y went up changing the U.S. 101 signs to Interstate 5 in 1964, including full length of Golden State Freeway which
