270-404: A disregard for the ethnic Mexican American population of metropolitan Los Angeles. The "Boyle–Hollenbeck Anti–Golden State Freeway Committee" was formed for the purpose of blocking or rerouting the freeway. Then– Los Angeles City Council member Edward R. Roybal chaired that committee. Despite this opposition, the construction of the freeway went ahead. When this section was completed in 1956,

360-625: A faster and more direct north–south route through the state and so was eventually chosen. Construction began in the early 1960s. There were just three phases for the 321 mi (517 km). The first phase, completed in 1967, ran from the San Joaquin County line to Los Banos. The second phase, completed in 1972, extended the freeway south to Wheeler Ridge and connected it to SR 99. The freeway then started to see traffic, as in Stockton there were only 4 mi (6.4 km) between

450-485: A new, larger bridge to replace the old M Street railroad bridge over the river with a combination rail and automobile bridge that would become the Sacramento's iconic Tower Bridge , forming a grand western gateway to the mall.

I-5 continues along the western city limits of Santa Clarita and passes Six Flags Magic Mountain , intersecting SR 126 just north of there. The Golden State Freeway then rises sharply, passing by Lake Castaic and undergoing a unique crossover resulting in

1530-467: Is still listed as a control city on northbound I-5 between SR 99 and I-580. Interstate 5 in downtown Sacramento closely follows the Sacramento River. This has resulted in complex engineering work to keep the section dry due to it being located below the water table. Locally, Caltrans refers to this part of the freeway as the "Boat Section". Due to record levels of rainfall in 1980 the Boat Section

1620-595: Is the current route of I-5. Both routes were eventually built as freeways. The Gavin Canyon route became I-5, and the main north–south route via the Ridge Route. The Newhall Pass route became SR 14, which is the main route between Los Angeles and the growing high desert communities of the Antelope Valley . It is also still a part of the important Midway Route, which is the primary alternate route when I-5

Capitol Mall - Misplaced Pages Continue

2880-464: The Capitol, Capitol Mall was once known as M Street . It was renamed Capitol Avenue by Governor C. C. Young in 1928. The Capitol Mall was previously part of State Route 275 , but was relinquished to the city in January 2006. Following California's cession by Mexico and entry into the union as a state in 1850, San Jose , Vallejo , and Benicia each briefly served as the state Capitol until

2970-579: 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 the north side of downtown, the Golden State Freeway follows the Los Angeles River , intersects SR 110 and SR 2 and passes along

3060-683: The Golden State Highway (US 99, later SR 99) into a freeway. The other was to use the proposed West Side Freeway (current Interstate 5), which had been endorsed by local groups as early as 1945. The Golden State Highway route would serve many farming communities across the San Joaquin Valley, but the West Side Freeway proposal would bypass all the Central Valley communities and thus provide

3150-585: The Pershing Drive exit. The portion of I-5 from the Mexican border to SR 94 at downtown San Diego is named the John J. Montgomery Freeway in honor of John J. Montgomery , a pioneer aviator who flew a glider from a location near Chula Vista in 1884. I-5 continues northwest from downtown as the San Diego Freeway until it reaches its junction with I-8 , then turns slightly to the north while passing SeaWorld and Mission Bay . Thereafter, I-5 intersects

3240-532: The Sacramento River into Yolo County . In Woodland , the SR 113 freeway merges with I-5 before exiting to the north. The Interstate heads northwest again toward Dunnigan , where it converges with I-505 . I-5 skirts north along the western edge of the Sacramento Valley , bypassing the larger cities of the region, including Yuba City , Oroville and Chico , before reaching Red Bluff . From Dunnigan, I-5 enters Colusa County , passing through

3330-652: 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 the city limits of San Diego. I-5 subsequently intersects with four state routes: the southern end of SR 15 (the extension of I-15 ), SR 75 and the Coronado Bridge , the western end of SR 94 , and SR 163 . In addition to serving downtown San Diego, I-5 also provides access to Balboa Park from

3420-518: The San Francisco Bay Area. From here, I-5 crosses the California Aqueduct for the final time and intersects SR 132 , a major route to Modesto and the mountains in the east, as well as the northern end of SR 33. After passing Tracy, I-5 intersects I-205 , a connector route to I-580, before intersecting the SR 120 freeway near Manteca . After passing through Lathrop , I-5 heads due north through Stockton, intersecting

3510-579: 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

3600-576: The Tejon Pass and Grapevine typically gets snow at higher elevations during the winter. Although Caltrans may require vehicles to use snow tires , snow chains , or other traction devices during and after snowstorms , the California Highway Patrol will instead usually close this segment altogether during these conditions because of the steep grade of the pass, and the amount of passenger traffic and big-rigs that generally use

3690-630: The Utica Avenue exit to I-580, I-5 parallels the eastern foothills of the Diablo Range . It crosses the California Aqueduct for the second time. In Kings County, I-5 intersects SR 41 before briefly entering the city limits of Avenal, where it intersects SR 269 .

3780-480: The West Side Freeway (I-5) saw the development of businesses serving the needs of travelers. For years, there has still been interest in designating the Golden State Highway route as its own interstate, I-7 or I-9 . The median on I-5 between Wheeler Ridge and Tracy is wide enough to accommodate widening the West Side Freeway to six or eight lanes, should the need arise. I-5's more direct Los Angeles-to-Sacramento route bypasses San Francisco, San Jose , Oakland , and

3870-431: 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

3960-426: The border, I-805 splits off to the northeast and serves as a bypass of I-5 that avoids downtown San Diego . I-5 itself continues northwest and meets 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

4050-399: The carpool lanes of SR 14 and I-5 opened in 2014. The second phase was between Buena Vista Street and SR 170, and the carpool lane opened in 2014. This phase also included a flyover between the existing carpool lane of SR 170 and the newly constructed I-5. The freeway in this phase went through no improvements, and used existing median shoulders to construct the HOV lane, thus all

4140-399: The city acquired the two additional blocks west of the Capitol for the construction of State Office Building No. 1 and the Library and Courts Building in 1913, the area between 9th street and the river continued to be developed with residential, commercial, and community properties, including Sacramento's historic Japantown , which spanned M street at 4th street from K to P streets, clogging

4230-407: The city of Williams and intersecting SR 20 . In Glenn County , I-5 intersects SR 162 in Willows and SR 32 in Orland . I-5 then crosses into Tehama County , passing through Corning before entering Red Bluff and intersecting SR 36 , which connects to the northern end of SR 99. I-5 crosses the Sacramento River twice before entering Shasta County . I-5 then enters

4320-433: The collapsed flyover ramp from SR 14 south to I-5 south. After both earthquakes, the collapsed portions were rebuilt and surviving portions reinforced. In the evening of October 12, 2007, two trucks collided in the southbound tunnel that takes the truck bypass roadway under the main lanes near the Newhall Pass interchange. Fifteen trucks caught fire, killing three people and injuring ten. The Ridge Route refers to

4410-399: The corridor. Whenever there is such a closure, traffic must either wait for it to reopen, or endure a multi-hour detour. An automated gate on the freeway's median in Castaic north of Lake Hughes Road allows drivers to turn around when such closures occur. From SR 99 at Wheeler Ridge to Woodland , I-5 is known as the West Side Freeway. I-5 parallels SR 33 , skirting along

4500-433: 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

4590-428: The docks via riverboat in Old Sacramento . The advent of the automobile and the new Legislative Route 6 leading to the Capitol further emphasized how the appearance of the Capitol from the riverfront reflected California's fortunes, as urban planning advocate Charles Mulford Robinson petitioned the city and the state to emulate Pierre L’Enfant 's ideals for the National Mall in Washington, D.C. in 1907.

It briefly enters the city of Glendale and then Burbank , passing near Burbank Airport before reentering the Los Angeles city limits and intersecting 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:

4860-441: The far more remote western edge of the Central Valley , and is largely removed from the major population centers such as Bakersfield, Fresno and Modesto ; other state highways provide connections. I-5 still runs within the vicinity of Avenal , Coalinga , Los Banos , and a handful of other smaller cities on the western edge of the Central Valley. For most of this section, the Path 15 electrical transmission corridor follows

4950-443: 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

5040-436: The freeway. After entering Kern County, the freeway sharply descends for 12 mi (19 km) from 4,144 ft (1,263 m) at the Tejon Pass to 1,499 ft (457 m) at Grapevine near the southernmost point of the San Joaquin Valley , approximately 30 mi (48 km) south of Bakersfield and 5 mi (8.0 km) south of its interchange with SR 99 at Wheeler Ridge . This stretch of I-5 through

5130-617: The gateway to downtown, the busy intersection of 3rd Street and Capitol Mall, 300 Capitol Mall stands 18 stories high with 383,238 square feet of rentable area. The tower was designed by Daniel, Mann, Johnson & Mendenhall (DMJM) and completed in 1984. 301 Capitol Mall is the site of the former home of the Sacramento Union newspaper. Construction began here in 2006 for The Towers on Capitol Mall I & II , two planned 53-story and massive 615 feet (187 m) mixed-use towers. The project had been on hold since January 2007 due to liens being filed against developer. Located at 400 Capitol Mall,

5220-475: 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

5310-567: 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

5400-433: The legislature decided Sacramento best suited their needs for the state in 1854. Their initial allocation for the construction of the dedicated Capitol building in 1860 only provided for a 4 block parcel of land bordered by L, N, 10th, and 12th streets. Previously just another minor lettered street, M Street suddenly became a focal point for visitors to the Capitol as they arrived at the Central Pacific Railroad station or

5490-570: 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 is about 80 miles (130 km) west of the highway. I-5 is known colloquially as "the 5" to Southern California residents and "5" to Northern California residents due to varieties in California English . I-5 also has several named portions:

#1732772119214

5580-538: 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

5670-467: 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

5760-423: 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

5850-485: The next 18 mi (29 km). Toward the northern end of its routing through Camp Pendleton, I-5 passes through San Onofre State Beach and near the San Onofre Nuclear Generating Station . I-5 enters Orange County at the Cristianitos Road exit. Upon entering Orange County, I-5 goes through San Clemente . At Dana Point , I-5 turns inland while SR 1 continues along the coast. I-5 then heads due north through San Juan Capistrano and Mission Viejo , intersecting

5940-424: 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 the carpool lanes on the SR 170 and SR 14 freeways (an additional direct connector with the HOV lanes on I-405 near Mission Hills

6030-408: 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,

6120-403: The only direct access to SR 56 going northbound. North of the San Diego city limits, I-5 enters the city limits of Solana Beach , and then three incorporated cities to the north: Encinitas , Carlsbad and Oceanside . In Oceanside, I-5 intersects the SR 78 freeway and the SR 76 expressway and continues through Camp Pendleton . It then follows the Pacific Ocean coastline for

6210-462: 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

6300-457: 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

6390-414: The post war era jumpstarted the city's attention towards finally creating the Mall, if only to give government the excuse to seize the overcrowed ethnic ghettos through eminent domain , such as what was then called Sacramento's "West End" filled with minorities with no place else to go. Sacramento's city council approved a plan to acquire land and create a Civic Improvement District around the Capitol all

6480-431: 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

6570-486: 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

6660-466: 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

6750-632: 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

6840-487: 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

6930-458: 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;

7020-581: 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

7110-622: The view of the Capitol such that the noted city planner Werner Hegemann wrote, "that even walking on the sidewalks of “M” street the Capitol Building cannot be seen," and that clearing such, "is of the greatest importance for the future of Sacramento." Governor C. C. Young renewed efforts for the widening of M Street into a grand mall to create “the Pennsylvania Avenue of California” in 1929. He also advocated for renaming M Street as Capitol Avenue , and building

7200-457: The war, California 's population doubled due to its strong wartime defense industry production, many who moved into the vacated Japanese areas, especially those who were prohibited from finding housing elsewhere else due to racial housing covenants , often far exceeding the capacity for those properties as affluent residents moved out to the growing suburburan migration of the 1950s. That migration and federal investment in urban renewal during

7290-538: The way down to the river in 1947, recommending a 40 foot building setback from Capitol Avenue . The Sacramento Redevelopment Agency (SRA) was created in 1950 to deal with the challenge of enforcing the State's wishes, acquiring approximately 15 square blocks for the Capitol Mall Project, and publicly demolishing an 1870's private home acquired through eminent domain by the agency in a special ceremony in what

7380-783: The westerly side of the San Joaquin Valley , Sacramento , and Yreka ; also passing near Santa Ana , Glendale , Woodland , and Red Bluff . I-5 is part of the California Freeway and Expressway System , and is part of the National Highway System , a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration . The segment of I-5 from State Route 89 (SR 89) to US 97 forms part of

7470-642: The western end of SR 52 near La Jolla before entering University City . At Nobel Drive, the San Diego LDS Temple towers over I-5. Shortly afterward, I‑5 passes through the UC San Diego campus and intersects the northern terminus of I-805 before continuing north and intersecting the western end of SR 56 . At this interchange, there is a local bypass that provides the only access to Carmel Mountain Road from both directions and provides

7560-419: Was assigned as the design engineer for the project with Donald Van Riper as the landscape architect. Unfortunately, an earlier plan to include a round-about encircling a monument or obelisk on the western end of The Mall was abandoned due to the unanticipated construction of Interstate 5 to run along the river through the city, and deliberately built below grade so not to interrupt the clear line of sight between

7650-400: 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

7740-402: 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

7830-442: 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

7920-546: 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

8010-490: Was publicized as a “slum clearance project,” and opening those parcels up to private investment compatible with the State's mall concept. By 1961, the initial plan to create a 52 foot grassy median separating 2 wide streets with an 8 footwide landscape setback planted with Linden trees for a total of 180 feet between the buildings north and south of the Mall was underway. J. W. Wilson from the State Division of Highways

8100-603: Was under construction from 1860 to 1874. The capitol and grounds are a California Historical Landmark , a National Historic Landmark District, and on the National Register of Historic Places in Sacramento County, California . Sacramento Regional Transit District —RT serves public transport to/from and along the Capitol Mall. RT serves the city of Sacramento, and much of the northern portion of Sacramento County . RT has two light rail stops located on
