Routing Routing

  1. Rte 78 Seg 1From Route 5 near Oceanside to Route 15 near Escondido.

    Post 1964 Signage History Post 1964 Signage History

    In 1963, this segment was defined as the route from “Route 5 near Oceanside to Route 395 near Escondido.”

    In 1969, Chapter 294 changed “Route 395” to “Route 15”.

    Pre 1964 Signage History Pre 1964 Signage History

    In 1934, Route 78 was signed along the route from Jct. US 101 near Oceanside to Jct. US 99 near Kane Springs, via Ramona. This was once routed along Vista Way, Santa Fe, and Mission Road to Escondido. It was LRN 196, which was originally defined to run from LRN 2 (US 101) to LRN 77 in Vista. LRN 197 was defined to run from LRN 77 in Escondido, so it appears as if the portion between Vista and Escondido was part of the LRN 77 routing. However, in 1947 the definition of LRN 196 was changed to terminate simply at Vista, and in 1951 it was changed to terminate at LRN 77 near Escondido (US 395), making it likely that in 1951, the route between Vista and Escondido was transferred (with no change to LRN 77) from LRN 77 to LRN 196.

    By 1935, Division of Highways County Maps showed Route 78 following LRN 196 on Vista Way between US 101/LRN 2 Oceanside east to US 395/LRN 77 in Vista.  Route 78 multiplexed US 395/LRN 77 east from Vista to Escondido via Santa Fe Avenue, Mission Road and what is now Mission Avenue.  Within Escondido, Route 78 and US 395 multiplexed via Broadway where Route 78 split east onto LRN 197 via Grand Avenue.

    In the late 1940s, US 395/LRN 77 was modernized between San Diego and Riverside. The new alignment of US 395/LRN 77 provided a direct north/south routing between San Diego and Riverside by way of Escondido.  The new alignment of US 395/LRN 77 removed the multiplex of Route 78 between Vista and Escondido.  As a result, in 1947 the legislature altered the definition of LRN 196 as terminating at Vista instead of LRN 77. In 1950, the new 18.3-mile alignment of US 395/LRN 77 opened, routed directly north from Miramar towards Temecula via Escondido.  The new alignment of US 395 left Route 78 alone aligned over what had been LRN 77 between Vista-Escondido.  For a brief period, the former LRN 77 was not in the state highway system. In 1951, the legislature extended LRN 196 from Vista to LRN 77 in Escondido.  This measure brought Route 78 between Vista-Escondido back under state maintenance as part of LRN 196.

    Rte 78 Oceanside to Vista 1951In 1951, a proposed route was floated for Route 78 between Oceanside and Vista. The initial project would be a four-lane divided expressway. A separated intersection would be provided with US 101 (eventual I-5) in Oceanside. The route would be improved so that traffic could go faster than 25 mph, and it would be raised to prevent flooding. The section of highway between Vista and Escondido that was part of the state highway system prior to the relocation of US 395 in 1948 has been restored to state highway status and will be an easterly extension of Route 78.

    During 1959, the entire planned corridor of the Route 78/LRN 196 freeway between Oceanside and Escondido was added to the Freeways and Expressway System. Construction funding was made available during 1960. Construction continued through the 1960s. Ultimately Route 78 west of Vista to I-5 in Oceanside was constructed to freeway standards from 1967 through 1973. During 1968, much of what had been Route 78 on Mission Road and Santa Fe Avenue in the Escondido-Vista corridor was designated as San Diego County Sign Route S14

    I-5/Route 78 Interchange (11-SD-078 0.0)

    Rte 5 / Rte 78 InterchangeThe SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, provided the following expenditures on or near this route: High Priority Project #3206: I-5 and Route 78 Interchange Improvements. $4,000,000.

    In June 2015, it was reported that Caltrans is in the process of rebuilding the I-5/Route 78 interchange (11-SD-078 0.0) that spills traffic into a residential neighborhood. Caltrans first shared information on proposed interchange improvements in January 2015, and followed up with additional community briefings since then. This was reolated to a number of planned I-5 corridor improvements, and the necessity to upgrade both ends of Route 78 before future work on I-5 begins. The roadway improvements would be designed to ease expected traffic flow for 30 years out. There was a specific community concern about flyovers; the community wanted flyovers to be eliminated as an idea. Caltrans indicated that a flyover would be studied for traffic, cost and impact on neighborhoods, along with other alternatives. However, they appreciated community feedback, and it provided Caltrans great ideas, including consideration of a roundabout and bike lane. In addition to objections to noise and pollution, residents expressed concern over the lack of progress in Buena Vista Lagoon restoration, which the interchange will cross. Another big concern of residents and city council members was the speed of traffic that exits the interchange and barrels through a South Oceanside neighborhood.

    In January 2022, it was reported that the congested interchange between state Route 78 and I-5 in North County could be upgraded with federal infrastructure money. The junction connects two heavily traveled freeways, but instead of an uninterrupted transition, vehicles in the westbound lanes of state Route 78 must wait at a stoplight to turn south to get onto I-5. This leads to back-ups in the westbound lanes causing delays as long as 15 minutes during rush hour and increasing the risk of accidents. To modernize the interchange, officials plan to build a flyover overpass that would route cars over existing lanes, according to the San Diego Association of Governments. It would replace the traffic light and allow vehicles on Route 78 to merge seamlessly onto I-5 without slowing or stopping. The $1.2 trillion federal Infrastructure Investment and Jobs Act, passed in November 2021, authorizes funding to modernize roads, bridges, rail, ports, water systems and broadband lines. California’s share includes $29.5 billion for roads and bridges, which officials hope to tap for the interchange. The federal Department of Transportation will provide $4.8 billion to California immediately and CalTrans will administer the money within the state. The North County interchange project requires two or more years for environmental review and engineering plans. After that construction of the new interchange could be completed within about 18 months.

    There are plans to construct an eastbound auxiliary lane in Oceanside from the El Camino Real Overcross (~ SD 1.483) to east of El Camino Real Overcross. July 2005 CTC Agenda.

    In May 2012, the Oceanside Planning Commission approved plans to construct an interchange between Route 78 and Rancho Del Oro Drive (~ SD 2.367). The interchange would be for westbound traffic only. Dropped from the plan was a proposal to connect segments of Melrose Drive south of Route 76 to create a link to the highway.

    In January 2007, the CTC considered relinquishment of right of way in the City of Vista, at Melrose Drive, consisting of reconstructed and relocated city streets. The City, by freeway agreement dated February 13, 1996, agreed to accept title upon relinquishment by the State. (~ SD 6.01)

    Rte 78/Int 15 Managed Lanes ConnectorThere are early plans to expand this route in Escondido (~ SD R16.337). The plans could result in either two car-pool lanes or two toll lanes from Oceanside to Escondido by 2020. If car-pool lanes are picked, they would provide designated space for buses, car pools, van pools and solo drivers willing to pay a fee. Toll lanes would be open to everyone…. for a fee.The study should be completed in Spring 2012. In 2009, Route 78 handled an average of between 120,000 and 160,000 weekday vehicle trips, according to the California Department of Transportation. Route 78 was built in the 1970s and widened from four lanes to six in 1993.

    In October 2020, it was reported that SANDAG was holding a virtual meeting to get public input on improvements to the I-15 and state Route 78 interchange. These are still five years away and will depend on funding. A study to evaluate plans to improve Route 78 was completed in 2012 and some construction improvements just west of the I-15/SR 78 interchange were implemented. SANDAG and Caltrans have proposed additional improvements to this corridor, including the I-15/Route 78 Managed Lanes Direct Connectors Project, the I-5/Route 78 Interchange Project, the Route 78 Managed Lanes Project, and operational improvements along Route 78. Other long-term projects include future double tracking and express services for the SPRINTER and the construction of additional segments of the Inland Rail Trail Bike Path. First up is the I-15/Route 78 Managed Lanes Direct Connectors Project, for which environmental studies are starting. Specifically, the project will improve connectivity by:

    The history of this segment dates back to the Banner Toll Road, which was constructed around 1870 between the towns of Julian and Banner.  By 1874 the Banner Toll Road was purchased by San Diego County and made accessible to the public.  During the early 1920s the existing Julian Road and Santa Ysabel Grade were reconstructed by San Diego County from Ramona east to Julian. By 1925 San Diego County had constructed a new road from Banner east to LRN 26 (US 99, now Route 86) near Kane Springs.

    In 1934, Route 78 was signed along the route from Jct. US 101 near Oceanside to Jct. US 99 near Kane Springs, via Ramona. It was LRN 197 between Escondido and Ramona (junction Route 67). It was LRN 198 between Ramona and near Kane Springs and the junction with US 99 (LRN 26; now Route 86). Both LRN 197 and LRN 198 were defined in 1933.

    By 1935, Route 78 and US 395 multiplexed within Escondido via Broadway where Route 78 split east onto LRN 197 via Grand Avenue.  From Escondido Route 78 followed LRN 197 east via San Pasqual Valley Road and Pine Street to LRN 198 in Ramona.  Route 78/LRN 198 from Ramona followed Julian Road east to Santa Ysabel where it picked up a multiplex of Route 79 southbound.  Route 78/Route 79 followed Julian Road east from Santa Ysabel to Main Street in the community of Julian.  From Julian Route 78/LRN 198 followed Banner Grade east to the Imperial County Line.  Within Imperial County, Route 78 followed LRN 198 to a terminus at US 99/LRN 26 near Kane Springs.

    The portion of the Rout between former Route 79 and Route 86 was part of the planned Imperial Highway. The name "Imperial" refers to the Imperial Valley, which took its name from the Imperial Land Co., a subsidiary of the California Development Company charged with reclaiming the water-starved but arable land east of San Diego for agricultural purposes in the early 1900s. The company began building canals in 1900, diverting water from the Colorado River for irrigation, and forming the Salton Sea in the process. The Los Angeles area wanted to patch together a superhighway that would stretch from the Pacific all the way to Brawley in the Imperial Valley, a distance of 215 miles; the route was later extended a few miles farther south to El Centro. The most route roughly followed the old Butterfield Stage overland route, established in 1858: across the desert (Route 78) and along today’s Route 79 to Temecula, where it headed on to Corona via Lake Elsinore and Temescal Canyon (Route 71, later I-15). There the road turned left down the Santa Ana Canyon on its way to Yorba Linda (present-day Route 91) and La Habra (present-day Route 90), then across Los Angeles County to meet the sea at El Segundo (as Imperial Highway, although it is paralleled by I-105). The extension to Brawley was along Route 86 The early Imperial Highway plans involved connecting a patchwork assortment of roads of varying length and quality.  In 1912, a group of Los Angeles boosters informally known as the Committee of One Hundred, working with Los Angeles, San Bernardino, Orange, Riverside and Imperial counties, settled on a route along the edge of the inland Salton Sea that completely bypassed San Diego County, from which Imperial County had been split off in 1907. The Los Angeles section of road would be mostly a straight shot from LAX to Anaheim, where the proposed road would dip south diagonally before eventually reaching the Imperial Valley. By the 1920s, the efficacy of the Imperial Highway concept had become apparent, and a new and more forceful private group, the Imperial Highway Association, was formed in 1929 to encourage the regions involved to mount a fully cooperative effort, including working closely with San Diego County, to get the job done. The association adopted an official route for a more streamlined, uniform highway in 1931 that ran slightly west of the earlier Salton Sea route. The improved roadway, now referred to informally as “the Cannon Ball Road,” would eliminate tight right angle turns that slowed trucks, smooth and widen the various roadways involved, and have new bridges where necessary. A major section in Yorba Linda was completed in 1937. Two-lane portions of the highway through Inglewood had to be expanded to four. A  bridge over the Los Angeles River, completed in 1951, eliminated a crucial bottleneck; it replaced an old one that collapsed in 1948. The final section of the Imperial Highway as envisioned by the association was completed, and it was dedicated a scenic highway in a ceremony on the Imperial-San Diego county border in December 1961. Of its 220 total miles, 77 were county roads, with the rest being state highways. The cost to complete the project was estimated at $16 million (about $138 million in 2020 dollars). In 1965, Caltrans planned a new freeway along the path of Imperial Highway, from LAX to Norwalk. It opened in 1993 as I-105, though Imperial Highway itself remained in place, if somewhat less crucial than it once was. Through Orange County, Imperial Highway was Route 90. Major chunks of the roadway through Riverside and San Diego counties were subsumed by newer freeways and highways over the years. The 41-mile Los Angeles stretch, which passes through El Segundo, Hawthorne, Inglewood, South Los Angeles, Lynwood, South Gate, Downey, Norwalk, Santa Fe Springs and La Mirada, retains the original Imperial Highway name, as does a section of Route 86 in El Centro (also known as Imperial Avenue).

    Escondido Reconstruction (North Broadway (SD N17.705) and Flora Vista Street (SD R21.298))

    Rte 78 Escondido ImpovementsIn January 2021, it was reported that Cal Trans was starting construction on a $19 million multimodal project to upgrade about five miles of Route 78 between North Broadway (SD N17.705) and Flora Vista Street (SD R21.298) in Escondido. Initial work will improve curb ramps for pedestrian access in accordance with the Americans with Disabilities Act. Other work will include vehicle to infrastructure (V2I) traffic signal upgrades, ITS upgrades and a Class III bike route. Subsequent construction will include removal and replacement of the pavement, high visibility striping, utility upgrades, and a shared bike lane. This project is expected to be completed in Fall 2021. The $19 million project is funded through the State Highway Operation and Protection Program (SHOPP).
    (Source: Escondido Times Advocate, 1/28/2021)

    In February 2021, more details were provided on this project. The project begins at Route 78 & Broadway, follows Broadway, down Washington, hangs a right on Ash Street and becomes San Pasqual Valley when it gets into the County, ending at Flora Vista, just after Summit Drive. Work will include repaving Route 78, reconstructing curb ramps for the Americans With Disabilities Act (ADA) compliance, vehicle to infrastructure (V2I) traffic signal upgrades, ITS (Intelligent Transportation System) upgrades and a Class III bike route. This is the first rebuild of the route in 15 years. For this project, all of the asphalt will be removed and replaced with a large stone matrix, similar to what is used on airports, in order to get more longevity in the pavement. Specifically, Caltrans will remove 6/10th of the asphalt, about 8 inches or so. The new asphalt will be of “airport quality”—this means a road of large stone matrix that is typically usually used for heavier vehicles such as an airplane. The project will be reconstructing eighty-three curb ramps to make them ADA compliant, and doing signal improvements at twelve intersections along the route. Safety improvements include upgrading guardrails and updating the traffic striping, including the addition of ‘sharrows’. Tech updates and improvements include installation of fiber optic cables and implementing some V2I (Vehicle-to-Infrastructure) modules that talk to smart vehicles, V2I sensors are used in intelligent transportation systems (ITS) to capture data and issue drivers with real-time advisories about such things as traffic congestions, construction sites, road conditions, and parking zones. As an example, Teslas have an app that can be used that will tell the driver what speed to drive at if they want to catch all the greens along the route. Plans are to complete the project by November 2021.

It was named in memory of Firefighter Steven Rucker of Novato, California. In late October 2003, Southern California experienced several devastating wildfires that exceeded the devastation of any fires in the past century. In San Diego County alone 400,000 acres burned, 2,600 homes where destroyed, and 17 lives were lost. Dedicated firefighters from across California and nationwide responded to the urgent call for assistance and put their lives and personal safety at risk to save the lives and property of the residents of San Diego County. Additionally, members of the Armed Forces courageously met their country's call to duty, providing valuable firefighting assets and assistance to California's emergency response efforts in keeping with the finest traditions of United States military service. Firefighters displayed courage and uncommon bravery in working the fire lines for long hours and with little rest, often while their own homes and families were in jeopardy elsewhere, and many of these firefighters lost their own homes to the fires while defending the lives and property of others. Through the tireless and heroic efforts of California's firefighters, volunteers, and members of the community, the historic town of Julian was ultimately saved from destruction by the wildfires. One of these firefighters, Steven Rucker of Novato, California gave the ultimate sacrifice and lost his life in San Diego County on October 29th, 2003 fighting the advancing fire line as it threatened the town of Julian and neighboring mountain communities.

The remainder was a proposed county route between Brawley and Palo Verde. It was constructed only between Palo Verde and Blythe. With the advent of the 1934 signage, the segment from Palo Verde to the Calfornia/Nevada border was signed as Route 195 (which continued to the California/Nevada border along LRN 146). After US 95 was signed in 1940, the portion N of Blythe to the Calfornia/Nevada border was signed as US 95, and the portion S of Blythe to Palo Verde, although part of LRN 146, was apparently unsigned. The portion between Brawley and Palo Verde was added to LRN 146 in 1959, although as it was constructed, it was signed as a county route. A 1967 map shows the routing between Midway Well and Route 115 as County Sign Route S78, with Route 78 signed with Route 115 between the Brawley area and US 80.

    In 1939, the American Association of State Highway Officials Executive Secretary proposed an alignment of US 95 south to Blythe. Subsequently, US 95 replaced Route 195 on LRN 146 from Blythe to the Nevada State Line.  The designation of Route 195 on LRN 146 south of Blythe to Palo Verde was deleted, leaving it without a Sign State Route. Signage for Route 195 was resassigned to what had been US 60/US 70 on LRN 64 in Box Canyon east of Mecca.  In 1959, the origin of LRN 146 was changed from Palo Verde near the Imperial County Line to LRN 187 (Route 115) east of Brawley.  The newly extended segment of LRN 146 contained a planned routing over the Algodones Dunes by way of Glamis and appears on the 1960 Division of Highways Map.  In late 1961, LRN 146 had a formal route adoption from Glamis to towards Palo Verde by the California Highway Commission.  Much of LRN 146 in the Glamis-Palo Verde corridor was adopted as expressway standard.

    By 1967, a county route -- Ben Hulse Highway -- had been completed between Route 115 and Palo Verde; it was shown as "planned" Route 78, but signed as County Sign Route S78. Only Route 78 from Glamis to Palo Verde had a determined State Highway routing.  The construction of a road to Glamis was difficult to due to the presence of the Alogodones Dunes.  The most practical route from Brawley to Blythe was initially via Niland-Brawley Road through the Chocolate Mountains. Within Riverside County Niland-Brawley Road emerged onto the Bradshaw Trail that ended at LRN 146 several miles north or Palo Verde. Existing Niland-Brawley Road in the Chocolate Mountains was sold to the Navy during February 1957 to fund construction the Glamis Road.  California State Senator Ben Hulse is quoted in a Los Angeles Times article from the era predicting the Glamis Road would become a State Highway.  The road connecting Brawley to Glamis opened on August 13, 1958.  The opening of the new road to Glamis saw it incorporated into the planned extension of LRN 146.  The completion of Ben Hulse Highway from Route 115 to existing Route 78 near Palo Verde occurred in 1964

    Status Status

    Brawley Bypass

    It appears there are plans to convert at least part of this to freeway. The April 2003 CTC had on its agenda the route adoption of a Freeway location for Route 78, northwest of the City of Brawley, to Route 111, southwest of the City of Brawley, in Imperial County. [11-Imp-78 KP R14.6/R24.8 (PM R09.1/R15.4) and 11-Imp-111 KP R33.0/R39.7 (PM R20.5/R24.7)]. There was also an item related to a negative environment impact for the project.

    The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, provided the following expenditures on or near this route:

    • High Priority Project #926: Construct highway connecting Route 78/Route 86 and Route 111, Brawley. This is likely the route being explored by the CTC back in April 2003. $7,600,000.

    In his 2006 Strategic Growth Plan, Governor Schwartzenegger proposed completing stages 2 and 3 of the Brawley Bypass. In November 2007, bids went out for construction of a 4-lane divided expressway and interchange on Route 78 near Brawley from 0.6 Km East of Hovley Road to 0.4 Km North of the Route 78/Route 111 Junction

    2007 CMIA. The Brawley Bypass on Route 78 was submitted to the Corridor Mobility Improvement Account for funding ($46.1 million). It was not recommended for funding.

    In February 2009, the CTC was noticed that Caltrans and the Imperial Valley Association of Governments (IVAG) recommended that Brawley Bypass projects programmed in the 2008 State Transportation Improvement Program (STIP) be reprogrammed as a corridor, with funding levels to be based on the state funds previously allocated by the California Transportation Commission (Commission) and available local and federal funds: (a) Route 78 Brawley Bypass — Stage 2 project (PPNO 0021F) (b) Route 78 Brawley Bypass — Route 86 to Route 111 project (PPNO 0021).

    In February 2010, the CTC approved some funding changes regarding the Brawley Bypass. Specifically, they amended the project agreement to reprogram $1,909,000 of Federal Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) Border Infrastructure Program (BIP) funds to the right of way phase on the Brawley Bypass (Stage 3) project (PPNO 0021G) in Imperial County. The purpose was to fund right of way activities related to additional impacts to agricultural land within the project vicinity. It should be noted this is a long project; the schedule shows environmental started in March 1993, and project closeout is expected to finish in January 2013 (construction should finish in February 2012). 

    In May 2012, the CTC amended the the Trade Corridor Improvement Fund (TCIF) baseline agreement for Project No. 77 – Brawley Bypass (Route 78/Route 111 Expressway) – Stage 3 Project (PPNO 0021G) in Imperial County. The amendment revised the project schedule and split off a follow-up landscape mitigation project (PPNO 0021Y). The approved baseline schedule was been revised to update the end of construction and closeout phases. The original construction schedule was developed assuming minimal structural construction on the project. However, during the design phase, a bridge was added to allow for canal maintenance, triggering an extended construction period.

    In December 2014, the CTC authorized relinquishment of right of way in the county of Imperial along realigned Route 78 between existing Route 86 (IMP R9.324) and New River (~ IMP R12.564) and along Route 86 between Fredericks Road and Gardner Road, consisting of a collateral facilities. The County, by controlled access highway agreements dated December 17, 1991 and May 6, 2003, agreed to accept title upon relinquishment by the State. The 90-day notice period expires December 1, 2014.

    In October 2012, the CTC authorized relinquishment of right of way in the city of Brawley on Route 78 (Main Street) between existing Route 86 and realigned Route 111, consisting of superseded highway right of way (~ 11-Imp-78-PM 13.2/15.5).

    In January 2012, the CTC authorized relinquishment of right of way in the city of Brawley along realigned Route 78 from Best Road (~ IMP R13.92) to Route 111 (~ IMP R15.464), consisting of collateral facilities.

    In December 2011, the CTC authorized relinquishment of right of way in the county of Imperial along Route78 between Route 111 and the realigned 111, and along Route 111 between Mead Road and Route 78, consisting of superseded highway right of way and collateral facilities. (11-Imp-78-PM 15.0/15.7, 11-Imp-111-PM 20.5/22.2)

    In May 2018, the CTC authorized relinquishment of right of way in the city of Brawley (City) along Route 78, 0.1 mile west of its intersection with Route 111, consisting of collateral facilities (11-Imp-78-PM 15.4/15.5). The City, by letter dated February 8, 2018 confirmed that the City Council, at their November 21, 2017 meeting, agreed to waive the 90-day notice requirement and accept title upon relinquishment by the State.

Statistics Statistics

Overall statistics for Route 78:

Pre-1964 Legislative Route Pre-1964 Legislative Route

The route that was to become LRN 78 was first defined in 1931 by Chapter 82 as part of “(l) Riverside to San Diego (Inland Route)”. The Inland route from Riverside to San Diego was an old established county routing that passed through many settlements and towns in plains and in narrow valleys lying in a semimountainous district between Riverside and San Diego. Riverside and San Diego counties had paved this route in the past, making a serviceable road for light traffic. The state still needed to improved the alignment, and the length of the ultimate State routing would be 20 miles shorter than the existing highway. It was added to the state highway system based on the volume of intercounty and intrastate traffic it carried, and by reason of relief it will afford to existing heavily traveled State roads and as an advantageous component of a comprehensive State system.

In 1933, it was extended with a segment from [LRN 12] near Descanso to [LRN 77] near Temecula. In 1935, it was codified into the highway code as:

  1. Riverside to [LRN 77] near Temecula
  2. [LRN 12] near Descanso to [LRN 77] near Temecula

This definition remained until the 1963 renumbering. It was signed as follows:

  1. From Riverside to LRN 77 near Temecula.

    This was originally signed as US 395, and is present-day I-215 (for a short while, this was I-15E). Prior to 1950, this also included the segment of Route 74 between Perris and Elsinore, and the segment of Route 71/US 395 between Elsinore and Temecula.

  2. From LRN 12 (US 80; present-day I-8) near Descanso to LRN 77 (US 395; present-day I-215 and I-15) near Temecula.

    This was/is signed as Route 79 between Descanso (US 80; present-day I-8) and Aguanga (present-day Route 79/Route 371 junction). Between Aguanga and Temecula, it was originally signed as Route 79, then resigned as Route 71 until 1974; it is present-day Route 79.
