# Interstate 5 in California

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 the Mexican border at the San Ysidro Port of Entry in the San Ysidro neighborhood of San Diego to the Oregon state line south of the Medford-Ashland metropolitan area. It is the longest interstate in California at 796.77 miles (1,282.28 km), and accounts for more than half of I-5's total length of 1,381.29 miles (2,222.97 km). It is also the second longest stretch of Interstate Highway (and 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 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: the John J. Montgomery Freeway, San Diego Freeway, Santa Ana Freeway, Golden State Freeway, and West Side Freeway.

## Route description

The entirety of Interstate 5 in California is defined in the California Streets and Highways Code as Route 5, which is defined as such in section 305:
   Route 5 is from the international boundary near Tijuana to the Oregon state line via National City, San Diego, Los Angeles, 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 the Volcanic Legacy Scenic Byway, an All-American Road. I-5 is also eligible to be included in the State Scenic Highway System; however, it is a scenic highway as designated by the California Department of Transportation (Caltrans) only from SR 152 to I-580.

### San Diego County

I-5 begins at the San Ysidro Port of Entry from Mexico in the San Ysidro neighborhood of San Diego. Immediately after 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 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 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 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 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 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.

### Orange County

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 the SR 73 toll road heading northwest. I-5 continues to the El Toro Y interchange with I-405 in southeastern Irvine, splitting into lanes for regular traffic as well as for truck traffic (though autos can use these lanes as well). From that point, I-405 takes over the San Diego Freeway designation, while I-5 becomes the Santa Ana Freeway as it runs southeast to northwest.
After the El Toro Y junction, I-5 intersects SR 133, a toll road that eventually connects to SR 241. Just before the Tustin city limits, I-5 passes over SR 261, the final toll road of the Eastern Transportation Corridor, but traffic must use Jamboree Road to access 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.

### Los Angeles County

After crossing the county line, I-5 goes through several cities southeast of Los Angeles, including La Mirada, Santa Fe Springs, and Norwalk. In Downey, I-5 intersects I-605, which serves as a north–south connector route between the cities east of Los Angeles, including those in the San Gabriel Valley. I-5 then enters Commerce, passing the Citadel Outlets shopping center, and intersects I-710 before entering 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 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 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 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 is planned). This allows a continuous HOV lane to run from Palmdale to North Hollywood via SR 14 to I-5 to SR 170.
I-5 continues along the western city limits of Santa Clarita and passes Six Flags Magic Mountain, intersecting SR 126 just north of there.

### Tejon Pass and Grapevine

The Golden State Freeway then rises sharply, passing by Lake Castaic and undergoing a unique crossover resulting in a left-driving configuration for about 5 mi (8.0 km) before the highway crosses back into its standard alignment. This section is known as the Five Mile Grade. After cresting the Five Mile Grade, the freeway enters the Angeles National Forest. It passes Pyramid Lake and intersects SR 138 before crossing the Tejon Pass through the Tehachapi Mountains near the Los Angeles–Kern county line, with Path 26 power lines generally paralleling 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 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 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.

### Central Valley

From SR 99 at Wheeler Ridge to Woodland, I-5 is known as the West Side Freeway. I-5 parallels SR 33, skirting along 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 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 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. In Fresno County, I-5 intersects SR 198 and SR 145 before running concurrently with SR 33 for several miles. I-5 then crosses into Merced County, intersecting SR 165, SR 152 and SR 33 near the San Luis Reservoir (where SR 152 provides a major connection to the Monterey Peninsula and the Silicon Valley), and SR 140 at the Stanislaus county line. I-5 crosses the California Aqueduct for the third time between SR 152 and SR 33 and again near Crows Landing.
In San Joaquin County, I-580 splits off from I-5 south of Tracy, providing a spur-route connection to 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 the SR 4 freeway that provides access to downtown Stockton. I-5 passes through the western portion of the Lodi city limits before intersecting SR 12 and entering Sacramento County.
I-5 enters the city of Elk Grove while passing along the eastern edge of the Stone Lakes National Wildlife Refuge. It then crosses into the Sacramento city limits, soon paralleling the Sacramento River before intersecting the Capital City Freeway, which carries US 50 and I-80 Business (I-80 Bus.). SR 99 merges with I-5 at this point, and the two routes pass through the western half of downtown Sacramento. Following the bridge over the American River, I-5 and SR 99 intersect the major transcontinental route of I-80. Just as I-5 leaves Sacramento, SR 99 splits off and continues north while I-5 turns due west past Sacramento International Airport and crosses 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 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.

### Cascade Region

I-5 then enters the Shasta Cascade region, intersecting SR 273 in Anderson before passing through Redding and intersecting SR 44 and SR 299. The freeway then continues through the city of Shasta Lake, intersecting SR 151, before crossing over Shasta Lake on the Pit River Bridge and climbing up to near the foot of Mount Shasta. Just north of the bridge over Shasta Lake, I-5 also boasts 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 the Klamath River and reaching the Oregon border and the Siskiyou Summit. From Red Bluff to the Oregon state line, I-5 is known as the "Cascade Wonderland Highway".
North of Redding, I-5 regularly gets snow at higher elevations from fall to spring. Caltrans sometimes requires vehicles to use snow tires, snow chains, or other traction devices in the mountains during and after snowstorms. Checkpoints are often set up to enforce chain restrictions on vehicles bound for icy or snowy areas. When chain restrictions are in effect, vehicles must have chains on 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.

## History
### Historical naming

The portion of this highway from Los Angeles to San Diego was also co-signed as US 101 until 1964–1968. The portion of this highway from Woodland to Red Bluff roughly follows old US 99W.
In California, the former western branch of Interstate 5 (the northern end of 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; 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.

### Los Angeles area

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 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, 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 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.

### Newhall Pass

The original route went through 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 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 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 is closed (via SR 58 and SR 14).
The interchange has partially collapsed twice due to earthquakes: the 1971 Sylmar earthquake and the 1994 Northridge earthquake. As a result of the 1994 collapse, this interchange was renamed the "Clarence Wayne Dean Memorial Interchange", honoring a Los Angeles Police Department motorcycle officer killed when he was unable to stop in time and drove off 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.

### Ridge Route

The Ridge Route refers to 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 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 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 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, 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 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.

### San Joaquin Valley

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 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 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 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 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-5W and the San Francisco Bay Area

I-5's more direct Los Angeles-to-Sacramento route bypasses San Francisco, San Jose, Oakland, and 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 is still listed as a control city on northbound I-5 between SR 99 and I-580.

### Sacramento area

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 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 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.

### Redding to Oregon

In 1992, Caltrans finished upgrading the final 13 mile segment north of Lakehead.

### HOV lane expansion in Southern California

I-5 through north San Diego County is currently undergoing expansion as part of the North Coast Corridor project. The carpool lane expansion from Lomas Santa Fe Drive to SR 78 fully opened by late 2023. As part of this expansion, the bridge carrying I-5 over San Elijo Lagoon was replaced with a much wider bridge. Previously in 2007, a carpool lane opened between Lomas Santa Fe Drive and I-805, with a continuation of the lanes on I-805 to Governor Drive opening in 2016. There are plans to construct 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 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 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 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 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 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 the Burbank Boulevard bridge replacement was completed in 2021. The fourth and final phase is in the Santa Clarita Valley, where Caltrans is undergoing construction to extend the carpool lane from the Newhall Pass interchange to Parker Road in Castaic. These lanes are scheduled to open to traffic in 2026. A fifth phase to build a flyover which will connect I-405's carpool lanes with I-5's is in 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.

## Unsigned State Route 5S

There are two non-contiguous, unsigned special routes of I-5 in Los Angeles County that both carry the hidden state designation of Route 5S (for "supplemental").

### Colorado Street Freeway Extension (exit 142)

The Colorado Street Freeway Extension is a short freeway spur that originally carried State Route 134 until it was moved north onto the Ventura Freeway. Since then, it has been signed as extended off- and on-ramps of I-5 exit 142/Colorado Street, with additional interchanges with Colorado Boulevard, Edenhurst Avenue, and San Fernando Road.
The entire route is in Los Angeles County. All exits are unnumbered.
