Routing Routing

Rte 94 Seg 1From Route 5 near San Diego to Route 8 west of Jacumba via Campo.

Post 1964 Signage History Post 1964 Signage History

The definition of this route is unchanged from 1963.

According to Andy Field, the western end of this route was originally to connect to Route 163. It is unclear if this would have been an all Route 94 loop in downtown San Diego, or part Route 163 and part Route 94.

Pre 1964 Signage History Pre 1964 Signage History

In 1934, Route 94 was signed along the route from San Diego to Jct. US 80 (I-8) at White Star, via Jamul and Campo. This originally ran along Campo Road, Federal Blvd, and Market Street (although it may have also run along Broadway) to Pacific Highway. It was LRN 200, defined in 1933.

Route 5 in San Diego to Route 125 near Spring Valley

Route 94 HOV / Express Lanes (~ SD 1.501 to SD 4.03)

[Map]In September 2007, the CTC approved a resolution to revise the project scope and update the schedule and funding plan for TCRP Project #77 – Route 94; complete environmental studies and construct HOV lanes from downtown San Diego (Route 5) to Route 805 in San Diego County (~ SD 1.501 to SD 4.03). In 2002, San Diego Association of Governments (SANDAG) developed an additional tax ordinance for transportation in the region, TransNet II. At the same time, SANDAG took the opportunity to study in detail both HOV lane needs and the development of Bus Rapid Transit (BRT) routes throughout the region. As the studies impacted the Route 94 alternative study, the decision was made to postpone further work on this project until final decisions were made by SANDAG. In November 2005, San Diego voters passed TransNet II. With the TransNet II funds now available, SANDAG, in conjunction with the Department, resumed the alternative study identifying several projects along the Route 94 corridor. As part of recent Regional Transportation Plan (RTP) updates, SANDAG has completed its HOV and BRT studies. These studies show a high priority need for critical HOV and BRT efforts on Route 94 between Route 5 and Route 805, while the Route 94 segment between Route 805 and Route 125 (the portion of original TCRP #77 limits) was shown as a lower priority need for HOV and BRT. To address the high priority need, Caltrans requested to reduce the limits of the project to the area between Route 5 and Route 805 only. The scope of the work would expand to include construction of HOV lanes and the implementation of BRT service from Route 15 to Route 805. It is anticipated that funding for the construction of the HOV lanes will come from a combination of local, State and federal sources. The schedule and funding for the segment between Route 805 and Route 125 will be addressed in the future under a completely separate project. It is anticipated that construction will be complete in FY2015/2016.

94 ExpansionIn 2015, it was reported that Caltrans has been studying the environmental impacts of adding Express Lanes along Route 94 between I-805 and Downtown San Diego. The addition of these Express Lanes would support the planned South Bay Rapid service, as well as carpools and vanpools along the route. Local and state representatives, as well as community stakeholders, along the project alignment have requested that Caltrans and SANDAG consider incorporating community-based alternatives into the SR 94 Express Lanes Draft Environmental Impact Report (EIR). Specifically, there was a request to study buses on shoulders options, general purpose lane conversions and access to transit from local communities along Route 94. The proposed Bus on Shoulder Project addresses the community’s request to study buses on shoulders in the Route 94/I-805 corridor on an interim basis. Caltrans will also be analyzing a general lane conversion alternative and providing direct access to existing and future Rapid services from the communities along Route 94, which requires evaluation of the I-15/Route 94 HOV direct connector. But by July 2015, community sentiment had turned. This resulted in a recent flood of letters from elected officials asking the San Diego Association of Governments (SANDAG) and Caltrans to not only explore putting a bus stop in the neighborhood, but to potentially scale back the freeway expansion. As it currently stands, the project would add an elevated ramp for buses and carpooling between I-805 and Route 94, which could stretch all the way to 30th Street, connecting to two new express lanes going into and out of Downtown. The two miles of new “managed lanes” would service carpooling and buses, linking up to “bus rapid transit” networks along I-15 to the north and a similar project planned along I-805 to the south.

In December 2009, the CTC relinquished right of way in the city of La Mesa along Routes 94 and 125 between Grove Street and Spring Street (~ SD 9.26 to SD R10.404R), consisting of relocated and reconstructed county roads and frontage roads. The County of San Diego, by freeway agreement dated September 30, 1968, agreed to accept title upon relinquishment by the State to roads which on that date were within an unincorporated area of the county and have since been annexed by the City.

Route 94 / Route 125 Interchange (~ SD R9.651R to SD T11.5)

IntersectionIn September 2000, the California Transportation Commission considered a $1.7 million phase 1 proposal (TCRP Project #87) for two new freeway connector ramps at the Route 94/Route 125 interchange. Total estimated cost is $90 million. This funding was extended in September 2005 as the project is ready to proceed. In April 2007, the CTC amended project 87.2 to orogram an additional $3,610,000 in TCRP funds for Project Approval & Environmental Document (PA&ED). This project will construct the ultimate two-lane freeway-to-freeway connectors from westbound Route 94 to northbound Route 125 and from southbound Route 125 to eastbound Route 94. The project will also widen Route 125 providing additional lanes from Spring Street to Lemon Avenue, and provide auxiliary lanes from the connectors to the next interchange at Lemon Avenue. The additional $3,610,000 for PA&ED was needed to study impacts to the large number of residential, commercial, and resource rich areas that will be impacted by this project. It is estimated that four years will be required to complete the needed environmental studies, complete the draft environmental document, circulate it for public comment, and gain final approval. The project is now scheduled for construction between FY 2012 and FY 2017.

TCRP Project #77 regarded an environmental study to add capacity to the Route 94 corridor between downtown San Diego to the Route 125 junction in Spring Valley. Currently, only the Alternative Analysis has been approved. The Alternative Analysis is to provide a thorough study of several alternative approaches to providing capacity enhancements. Study alternatives include, but are not limited to, reversible lanes, additional travel lanes (HOV and mixed flow), auxiliary lanes, and access improvement modifications. The environmental report/study will further evaluate the design alternatives from the Alternative Analysis. In 2002, San Diego Association of Governments (SANDAG) began development of an additional tax ordinance for transportation in the region, Transnet II. At the same time, SANDAG took the opportunity to study in greater detail both HOV lane needs and the development of Bus Rapid Transit routes throughout the region. As SANDAG’s studies impacted the Route 94 alternative study, the decision was made to postpone further work on the Alternative Analysis until final decisions were made by SANDAG. In November 2005, the San Diego voters passed Transnet II. With the Transnet II funds now available, interest in the Alternative Analysis has resumed in 2006 with SANDAG identifying several projects along the Route 94 corridor. The Department, working in conjunction with SANDAG, is now able to resume the Alternative Analysis study with greater knowledge of future improvements needed in the region and can proceed towards starting the environmental process.

In August 2016, the CTC approved for future consideration of funding a project on Route 94 (11-SD-94, PM R10.5/T11.5) and Route 125 (11-SD-125, PM 13.6/14.6) in San Diego County that will construct a freeway-to-freeway connection from southbound Route 125 to eastbound Route 94 in the city of La Mesa. The project is not fully funded. The project is programmed in the Traffic Congestion Relief Program. The total estimated cost is $188,496,000 for capital and support. Depending on the availability of funding, construction is estimated to begin in Fiscal Year 2018-19. The Department has identified the need for a scope change to reduce the number of connectors from two to one. An amendment will be placed on the October 2016 California Transportation Commission meeting agenda to reflect the scope change.

In January 2017, it was reported that construction had not yet commenced on this project, although some homes in the area had been sold by Caltrans. A fact sheet from January 2016 noted that the project encompasses two miles, with the freeway-to-freeway connector passing under the existing Route 125 and joining eastbound Route 94 between Bancroft and Kenwood drives, according to the fact sheet. Construction of two auxiliary lanes is planned: one lane along southbound Route 125 from Lemon Avenue to the connector and the other lane from the connector to Kenwood Drive. Other proposed improvements include replacing the Mariposa Street overcrossing, widening the Route 94 bridges over Bancroft Drive, constructing “bridge structures” on Panorama Drive and Echo Drive over the connector, and constructing noise barriers along Route 94 and Route 125. The estimated project cost totaled $71.33 million, with $5 million coming from the State Transportation Congestion Relief Program and $1.7 million in TransNet funds from the San Diego Association of Governments (SANDAG) for environmental studies. (“TransNet,” says SANDAG’s website, “is the half-cent sales tax for local transportation projects that was first approved by voters in 1988, and extended in 2004 for another 40 years.”) However, “construction of these improvements will be scheduled as funding becomes available.” In December 2016, Caltrans project manager Lou Melendez responded, when asked about the status of the project. “We stopped the project when we ran out of money.” He said Caltrans funds ran out in 2015, and the project was “put on a shelf.” Melendez said there was no funding because the SANDAG-sponsored Measure A failed in November. In the year “2021, things might improve”. The City of La Mesa is aware of the project status, and that it is awaiting funding, said Greg Humora, the La Mesa public works director/city engineer whose promotion to assistant city manager was announced at the December 13, 2016 city-council meeting. On December 15, Humora said the Route 125/Route 94 is the “number one interchange project in the county” and identified by “TransNet as a high-priority project.”

In June 2017, the CTC authorized the following TCRP allocation: Allocation Amendment - TCRP Project. Request the reallocation of $536,000 for Environmental on TCRP Project 87.2 – Build two new freeway connector ramp projects in San Diego County. (PPNO 0356) [Approved.]: This is a financial re-allocation of $536,000 for TCRP Project 87.2 – Route 94/Route 125; build two new freeway connector ramps project (PPNO 0356) in San Diego County. Re-allocate $536,000 in previously allocated funds for PA&ED.

The 2018 STIP, approved at the CTC March 2018 meeting, appears to allocate Advance Project Development Element (APDE) funding of $7.948M in FY18-19 for PS&E on PPNO 0356 Route 94/Route 125 Connectors.

The 2020 STIP, approved at the CTC March 2020 meeting, continued the programmed funding for PPNO 0356 "Rt 94/125 Connectors (APDE)".

In December 2016, the CTC authorized relinquishment of right of way in the city of La Mesa along Route 125 on Bowling Green Drive and Echo Drive (11-SD-125-PM 13.5/14.0) and along Route 94 on Panorama Drive (11-SD-94-PM 10.5/10.8), consisting of collateral facilities. The City, by letter dated August 1, 2016, agreed to waive the 90-day notice requirement and accept title upon relinquishment by the State.

Route 125 near Spring Valley to Route 188 near Tecate

In March 2012, the CTC authorized SHOPP funding on Route 94, in San Diego County, 11-SD-94 13.8/14.4 Near Lemon Grove, from Via Mercado Road to 0.1 mile east of Jamacha Boulevard. $1,600,000 to construct median barrier to improve safety by reducing cross centerline collisions.

In March 2013, the CTC authorized $13,008,000 to rehabilitate 30 lane miles of pavement to extend service life and improve ride quality for the segment near Jamul, from Route 54 to 0.2 miles east of Marron Valley Road (~ SD 14.927 to SD 30.069).

In December 2014, the CTC authorized relinquishment of right of way in the county of San Diego on superseded Route 94 (Old Campo Road) between Miller Ranch Road and Fair Oaks Drive near Jamacha (~ SD 15.515, SD R16.963), consisting of superseded highway right of way. The County, by letter dated October 9, 2014, agreed to waive the 90-day notice requirement and accept title upon relinquishent by the State.

In October 2012, the CTC authorized relinquishment of right of way in the county of San Diego along Route 94 at Steele Canyon Road (near Jamacha) (~ SD 17.351), consisting of collateral facilities.

In August 2017, it was reported that the Jamul Indian Village has given $1.1 million to the county to go toward traffic improvements along Route 94 (~ SD 20.652 to SD 22.711). The money is part of $3.4 million the tribe has pledged toward safety measures along the dark, winding highway in rural East County. The Jamul group and the county last April signed a contract that guaranteed that the tribe would commit $23 million to Caltrans to improve conditions issues along Route 94. The tribe also agreed to an additional $3.7 million in funding to the county for improvements. The tribe has promised more than $120 million altogether for public safety, law enforcement, transportation and firefighting for te residents and roads around its Hollywood Casino Jamul-San Diego. A news release sent Thursday from the Jamul tribe notes that it was recently informed that Caltrans “is unable to take the lead role on these highway improvements.” The tribe says it will now coordinate directly with the county for roadway improvements. Cathryne Bruce-Johnson, spokeswoman for Caltrans, said that the state agency “is not party to the Intergovernmental Agreement between the county of San Diego and the Jamul Indian Village for off-reservation roadway improvements.”

Roadway Realignment near Dulzura (SD 20.7/SD 38.9)

[Improvements]In November 2007, the CTC received notice of preparation of an EIR regarding construction of roadway improvements including adding passing lanes and upgrading existing lanes and shoulders to current standards on Route 94 near Dulzura in San Diego County between PM SD 20.7 and PM SD 38.9. The project is fully funded in the 2006 State Transportation Improvement Program, Congestion Mitigation Air Quality Program and San Diego’s Association of Governments Transnet Program. The total estimated project cost is $56 million. Construction is estimated to begin in Fiscal Year (FY) 2010-11.

In October 2016, the CTC amended the SHOPP as follows: 11-SD-94 29.6/29.8 | Route 94 Near Dulzura, from north of Marron Valley Road to south of Dutchman Canyon Road. Roadway realignment, curve improvement, and shoulder widening. During preliminary design, the excavation boundary increased. This will result in additonal easement and acquisition areas. Furthermore, to allow for future maintenance for proposed drainage outlets, additional utility relocations and access easements are required. These changes add $154,000 to the cost of the project.

In August 2018, the CTC authorized $4,711,000 in SHOPP funding for San Diego 11-SD-94 29.4/29.7: Route 94 Near Dulzura, from 0.3 mile east of Grande Creek Bridge to 0.1 mile west of Marron Valley Road. Outcome/Output: Roadway realignment, curve improvement, and shoulder widening. This project will increase safety and reduce the number and severity of collisions.

In May 2015, the CTC authorized relinquishment of right of way in the county of San Diego along Route 94 at Community Building Road (near Engineering Springs, S of Dulzura) (~ SD 30.608), consisting of a reconstructed county road. It also authorized vacation of right of way in the county of San Diego along Route 94 at Community Building Road, consisting of highway right of way no longer needed for State highway purposes.

Route 188 near Tecate to I-8 near In-Co-Pah Park via Campo and Jacumba Hot Springs

In August 2016, the CTC approved $3,450,000 for Route 94 near Campo, at Campo Creek Bridge No. 57-0120. Following a recent bridge inspection, it was concluded this bridge needs replacement due to extensive deterioration of the existing deck and timber stringers and the potential high scour threat to the bridge foundations. Temporary shoring has been installed; however, shoring could fail as a result of monsoonal rainstorms and flash floods, thus placing the bridge at risk of collapse. This project will demolish the existing bridge and construct new to current standards. (The new bridge appears to be 57-1259, constructed in 2016, at SD 050.64; the other two Campo Creek bridges date to 1947 and 1964)

The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, provided an expenditure for High Priority Project #1639: Resurface and construct truck lane at Route 94 and I-8 interchange. $2,400,000 . (SD 065.37)

Naming Naming

Martin Luther King Jr. FreewayThe portion of this route between Route 5 and Route 125 (~ SD 1.554 and SD R9.614) is named the "Martin Luther King Jr. Freeway". It was named by Senate Concurrent Resolution 67, Chapter 129, in 1989. Martin Luther King, Jr., (January 15,1929-April 4, 1968) was a seminal figure in the battle for civil rights in the United States. Martin Luther attended segregated public schools in Georgia, graduating from high school at the age of fifteen; he received the B. A. degree in 1948 from Morehouse College, a distinguished Negro institution of Atlanta from which both his father and grandfather had been graduated. After three years of theological study at Crozer Theological Seminary in Pennsylvania where he was elected president of a predominantly white senior class, he was awarded the B.D. in 1951. With a fellowship won at Crozer, he enrolled in graduate studies at Boston University, completing his residence for the doctorate in 1953 and receiving the degree in 1955. In 1954, Martin Luther King accepted the pastorale of the Dexter Avenue Baptist Church in Montgomery, Alabama. In December, 1955, he led the first great Negro nonviolent demonstration of contemporary times in the United States, the bus boycott in Atlanta. In 1957 he was elected president of the Southern Christian Leadership Conference. In the eleven-year period between 1957 and 1968, King traveled over six million miles and spoke over twenty-five hundred times, appearing wherever there was injustice, protest, and action; and meanwhile he wrote five books as well as numerous articles. He was named Man of the Year by Time magazine in 1963; and became not only the symbolic leader of American blacks but also a world figure. At the age of thirty-five, Martin Luther King, Jr., became the youngest man to have received the Nobel Peace Prize. When notified of his selection, he announced that he would turn over the prize money of $54,123 to the furtherance of the civil rights movement. On the evening of April 4, 1968, while standing on the balcony of his motel room in Memphis, Tennessee, where he was to lead a protest march in sympathy with striking garbage workers of that city, he was assassinated.

Until 1989, it was named the "Helix Freeway". This is named after nearby Mt. Helix, which itself was named after the local Helix species of snail. This probably has something to do with its spiraling base. The mountain's peak is 1,370'. Mt. Helix appears on the La Mesa city seal, and the name is applied to various landmarks and roads

The portion of this route E of Rout 125 (~ SD R9.614 to SD R13.529) is informally named the "Campo Freeway".

James Craig SchmidtThe portion of this route between Bancroft Drive and Avocado Boulevard in the County of San Diego (~ SD R11.09 to SD R13.367) is offically named the "James Craig Schmidt Memorial Highway." It was named in memory of James Craig Schmidt, who was born in 1927, in Peoria, Illinois. After graduating from high school, Schmidt enlisted in the United States Navy, and later attended Illinois Wesleyan University, the University of Illinois, and De Paul University Law School, becoming a member of the Illinois State Bar and later the California State Bar. In 1958, Mr. Schmidt moved to San Diego, married, and began his career in the savings and loan industry, becoming legal counsel and senior vice president with Home Federal Savings and Loan before later joining San Diego Federal Savings and Loan as executive vice president-managing officer. In 1967, Mr. Schmidt was appointed as Assistant Secretary for Business and Transportation under Governor Reagan, and was later appointed to the California Toll Bridge Authority and the State Transportation Board. Mr. Schmidt was involved in local transportation issues for many years in the County of San Diego, was instrumental in the removal of tolls from the San Diego-Coronado Bridge, and was a long-time board member of the San Diego Highway Development Association and the first recipient of its lifetime achievement award in 2011. Mr. Schmidt had a distinguished record of community service, as a member of many organizations and the recipient of numerous awards, including the designation by the City of San Diego of a James C. Schmidt Day in 2000 for his service and dedication to the city. As an avid sports fan, Mr. Schmidt attended every game of the San Diego Chargers from the date of their first game in San Diego in 1961, and helped launch the first Holiday Bowl in San Diego in 1978 and served as President of the 1986 Holiday Bowl and Chairman of the 1987 Holiday Bowl. Further, as a guest commentator for the Daily Transcript, Mr. Schmidt wrote regular articles on a wide variety of topics, including sports, transportation, housing, real estate, desalinization, and grand jury reports, helping to educate readers and document local history. James Craig Schmidt died of cancer in January 2013. Named on 9/27/13 by ACR 57, Res. Chapter 136, Statutes of 2013.

Border Patrol Agent Jarod Charles Dittman Memorial HighwayThe portion of Route 94 from post mile SD 24.50 to SD 29.50 in the County of San Diego is named the "Border Patrol Agent Jarod Charles Dittman Memorial Highway". It was named in memory of Jarod Charles Dittman, who was born in September 1979, in the City of Fargo, North Dakota and graduated from Philipsburg-Osceola High School in 1998. He later went on to graduate from Pennsylvania State University and became a member of a Civil War reenactment group, the 148th Pennsylvania Volunteer Infantry, Company C. Jarod served in the Pennsylvania Army National Guard and was later deployed to Kosovo, where he observed that the children there were in need of winter clothing. He orchestrated a drive to collect coats and boots in the United States and had them distributed throughout the countryside around Kosovo. Jarod continued in his service to his country and began his career as a Border Patrol Agent for the United States Department of Homeland Security on March 5, 2007, as a member of the 660th Session of the Border Patrol Academy. He was assigned to the Brown Field Station immediately after graduation from the academy and loved his career and his fellow agents. On March 30, 2008, while Border Patrol Agent Dittman was working the midnight shift, he was involved in a single vehicle rollover accident at approximately 1:00 a.m. in the morning when he was en route to his assigned work area from the Brown Field Station. Agent Dittman was found by another border patrol agent after he had been ejected from his service vehicle. Border Patrol Agent Jarod Charles Dittman was 28 years of age at the time of his death and is survived by his wife and his daughter. Named by Assembly Concurrent Resolution (ACR) 154, 8/17/2018.

Historical Route Historical Route

Route 94 from the junction of Jamacha Road in Rancho San Diego to the eastern terminus at the junction with Historic Highway Route 80 in Boulevard (~ SD 14.83 to SD R64.125) has been designated as “Historic Highway Route 94” This naming recognizes the history of Route 94. Route 94 was previously known as Campo Road or Old Route 200, which began as foot trails, and with great labor was improved to accommodate wagons and stagecoaches and, until 1918, was the main artery road from San Diego, California to Yuma, Arizona. In 1829, the trails provided access to the Jamul Rancho owned by Governor Don Pio Pico. In the 1880s, Campo Road provided necessary and difficult access for the backcountry pioneers to San Diego to sell their products and secure needed supplies. The first telegraph line from San Diego to Arizona followed the general route of Campo Road in 1874. The first horseless carriage trip on Campo Road from San Diego to Campo and back was made in 1904 by John Gay of Lakeside The early Campo Road was used by the United States Military during the Mexican Revolution in 1911, during World War I, and extensively during World War II for support of Camp Lockett located in Campo. Camp Lockett was the last home of the famous Buffalo Soldiers of the 10th Cavalry of the United States Army. On August 21, 1933, the title to Old Route 200 was transferred to the State of California and renamed Route 94. The beginning of Highway Route 94 at the time of transfer was in Lemon Grove at North Avenue and Imperial Avenue (now Lemon Grove Avenue), continuing through Spring Valley, Jamul, Dulzura, Cottonwood Grade, Potrero Grade, to Campo, then easterly along CampCreek and terminating at the junction of Route 12 at White Star, a total distance of about 66 miles. The San Diego and Arizona Railway, the last transcontinental rail link built in the United States, which was completed in 1919, crosses Route 94 in five locations, two at grade and three by bridge, and generally follows Route 94 all the way to Yuma. Named by Assembly Concurrant Resolution (ACR) 131, 6/2/2010, Resolution Chapter 33.

US Highway Shield ACR 123 (Resolution Chapter 104, 8/16/2006) designated segments of former U.S. Highway Route 80 in San Diego and Imperial Counties as Historic U.S. Highway Route 80, and requested the Department of Transportation to design and facilitate the posting of appropriate signs and take related actions in that regard. The resolution noted that US 80, largely parallel to current I-8, was a 180-mile highway spanning San Diego and Imperial Counties from San Diego Bay to the Colorado River, and played a major role in the development of this state during much of the 20th century. In 1909, California voters approved a statewide bond measure for road improvement purposes in the amount of $18 million, providing, among other things, funds to construct a road between San Diego and Imperial Counties, and their county seats of San Diego and El Centro. In 1915, a unique wood plank road was built over the Imperial Valley sand hills, resulting in a shorter route. In 1925, the federal government became involved in standardized highway route designations across the nation and even numbers were assigned to major highways running east and west, and odd numbers for highway running north and south. The numbering of highways proceeded in numerical order beginning in the north and east and continuing south and west, respectively, and, as a result, the routing along California's southern border was formally designated as US 80. This road, from San Diego to Tybee Island, Georgia, was adopted as US 80 on November 11, 1926. US 80 was the first ocean-to-ocean transcontinental highway to be completed, and portions of the route were known as the Bankhead, Broadway of America, Dixie, Lee, Old Spanish Trail, and Southern Transcontinental Highway.

In 1933, the route from "[LRN 38] near Camp Richardson to S end Fallen Leaf Lake" was defined to be a state highway. In 1935, that route was codified as LRN 94, and retained that definition until 1963. It ran from Route 89 near Camp Richardson to the south end of Fallen Leaf Lake, and was signed as Route 188 between 1964 and 1965. This was defined in 1933.

In a discussion on AARoads in June 2017, Sparker noted: Sometimes the reason for maintaining one of the old and otherwise useless LRN's was less than either noble or commercially viable; an example of this was old LRN 94, which ran from Route 89 near Richardson Bay near the south side of Emerald Bay up the hill to Fallen Leaf (about 4 miles), which was a small area comprised of a series of lodges; while the ownership of these was private, the lodges were often used for off-the-books conferences and/or political meetings by state officials (including legislators) and lobbyists or other entities desiring face-to-face meetings with those officials away from public scrutiny. The LRN was kept maintained and plowed during winter to expedite these "conferences" -- which according to "underground" Division of Highways lore, often morphed into multi-day poker games and/or drinking fests! By the early '60's, the usage of the facilities had declined to the point that state maintenance was no longer a "perk", so the 1965 deletion of numerous marginal routes (after '64 LRN 94 became the original Route 188) was applied to this one as well, with the Route 188 number re-used in San Diego County as the Tecate border access route some years later.
