[The new US 395 Cabrillo Parkway in 1948.] San Diego's first freeway wasn't Interstate 5 or Interstate 8 or Interstate 15, and certainly not Interstate 805 or for that matter any other Interstate highway, U.S. Highway 101 or even U.S. Highway 80. It was U.S. Highway 395.

In the 1930s, California Division of Highways planners and the city of San Diego were presented with a two-fold problem: the two-lane US 395 was becoming increasingly congested and difficult to navigate, and its corollary, that San Diego had no viable high-speed central north-south route. Murphy Canyon was too narrow to expand with the earthmoving technologies available, and it was too far east for direct downtown access. (This is ironic in the present day since of course Interstate 15, US 395's modern successor, runs down Murphy Canyon today.)

Fortunately, there was a natural corridor running right from downtown that was unoccupied, and parallel to US 80/US 395 on Park Blvd: Cabrillo Canyon. Cabrillo Canyon was named for explorer Juan Rodriguez Cabrillo, who (as mentioned in Part 1) discovered what would become San Diego in 1542. At the time, Cabrillo Cyn was something to be crossed over and not driven through, exemplified by the beautiful 1915 El Prado bridge carrying Laurel Street high and dry above the undeveloped canyon floor (which even had water in it, as the man-made Laguna del Puente). However, its unique topography was very promising to the highway engineers searching for an alternative route, who exclaimed in California Highways and Public Works that its numerous outshooting arroyos "branching out at right angles to the mesas between ... is peculiarly adapted to the economical construction of a freeway. The arroyos, combined with short structures for cross traffic, form a natural distribution system to all parts of the city."

Despite the enthusiastic reception of the new route, the long range plan for what would be called the Cabrillo Parkway took some time to come to fruition. An embryonic plan was submitted as early as 1932 by engineer Rowland Reed and promoted by local community boosters led by father and son George and Arthur Marston, but full right-of-way was not granted by the city of San Diego until 1941 and the only existing structure that could be used for the new highway was the 1915 bridge; fifteen others had to be constructed from scratch, the first one being the Washington St/6th St bridge built in 1940. Actual groundbreaking on the alignment itself was considerably delayed and did not occur until February 1946. Nevertheless, engineers made the most of the long gestation and planned it as a true parkway in the mold of the earlier and very successful Arroyo Seco Parkway (today's CA 110), even including paths for equestrian and hiker traffic, but also made sure attention was paid to design speed such that there were no at-grade crossings all the way from Ash St to Kearny Mesa. As part of the last portions of the project, 10th and 11th Streets in downtown San Diego were converted to southbound and northbound one-way streets, respectively, and a complex interchange was built with Mission Valley Rd, the future site of the US 80 freeway and modern Interstate 8, in the heart of Mission Valley.

[Overview of San Diego from Balboa Park to Linda Vista N, 1947, 126K.] The new $3.5 million, 7.1 mile Cabrillo Parkway was an immediate success. Opened on 28 February 1948 and signed as U.S. Highway 395 (cosigned with US 80 through Balboa Park, decommissioning the old Park Blvd alignment), it received a massive ribboncutting ceremony with the younger Marston, Reed, local dignitaries and military brass culminating in a mile-long auto parade from Balboa Park to Linda Vista. The scenic and picturesque landscaping and views of the new Park arterial are best appreciated on the 1947 aerial shot at right (click for a 126K large view in a new window); notice the lack of the Interstate highways and the relatively underdeveloped northern portion of the city towards the city limits. Heavily utilized as the central arterial the city and state had envisioned, the Cabrillo Pkwy became the plumbline of San Diego's new northern expansion and an important facilitator of the city's modern history. A typical view of the highway can be seen at the upper left of this page.

[Four-level interchange of US 395/I-5, 1964.] In just eight years, however, the formerly generous speed limit of 55mph on most sections was seen as a liability and the highway desperately needed an expansion to three lanes per direction. Unlike the Arroyo Seco, unfortunately, there was no breakdown lane to shoehorn into the tight design which had looked so spacious little more than a decade earlier, while its rechristening as the Cabrillo Freeway was nevertheless done without a trace of irony. The new US 80 freeway required considerable reconfiguration of the Mission Valley interchange in 1960, and with the construction of the Interstate 5 San Diego Freeway through downtown bringing even more traffic into the Cabrillo Fwy's southern end, a new four-level-style interchange (shades of the Arroyo Seco again) was built as part of the I-5 project in 1964 depicted at left during its early days. However, further expansion of the Cabrillo Fwy was not to be, because the huge sums brought in by the extension of Interstate 15 to San Diego in 1968 allowed a more favourable routing to be adopted. The expansion of the Cabrillo Fwy never happened, and after its designation as CA 163 in 1969 and the US 395 signs started to disappear, particular attention was paid to turning it back into the parkway it was originally designed as and recognizing its unique position in the history of San Diego. We'll see portions of this "retro-retrofitting" as we drive the modern highway completely from END sign to END sign. As befits its historic status, the Cabrillo Parkway became part of the National Register of Historic Places in 1996.

As a technical note, please excuse some of the strange angles used in this section -- the CA 163 Cabrillo Fwy is very difficult to photograph safely from the road, and creative measures and vantage points were needed to get a good shot and not impede traffic.

In this Part we will also start on the beginning of Pomerado Road, the old alignment of US 395 through Poway bypassed by the later US 395 freeway, which is now also part of Interstate 15. This very old routing has a number of fabulous roadgeeky wonderful things, more of which we will see in the next Part.


US 395 via the Cabrillo Freeway (1948-1969)

The Cabrillo Freeway and modern CA 163 start here today, just south of Interstate 5 and north of 11th Avenue and A Street. US 80 and US 395 of course proceeded south to US 101, and so did CA 163 until 1984; we talked about this in Part 1. I love old button copy signs, so I'm still using my old grotty 2005 picture despite these signs being replaced with new retroflective crap since.

Entering the "four level" with I-5 depicted in the background. One of my big pet peeves is this sign, at the very beginning of the Cabrillo Fwy (Pkwy), designating CA 163 as a "Historic Route: Historic Cabrillo Parkway." The bottom sign is fine. The top sign shows the wrong shield, because it should be US 395 in the Historic Route position, not the Johnny-come-lately CA 163, and the shield should be green: CA 163 never used white shields, because it was signed here well after Caltrans started using the current green shields in 1964.

The lame justification I hear for this error's continued existence is that signing it as US 395 would be confusing. However, a simple BEGIN CA 163 affixed to this sign would cure all its ills, and there's plenty of space. For that matter, this was also US 80 until the Alvarado Freeway was built.

If we abruptly turned left, hopped the median and committed several brazen traffic misdemeanours to head back south, we would see the southern END of CA 163 as it turns into 10th Avenue. US 395 headed south of here to Market and thence to US 101.

[Prado construction 2005, 89K.] NB CA 163 at the $225,000 (1915) Cabrillo Bridge, also known as the El Prado Bridge. This historic bridge was built in 1915 for the Panama-California Exposition to connect Laurel Street to El Prado, as depicted in this beautiful 1916 picture on Wikipedia which also shows the man-made Laguna del Puente at its base (the Laguna is where the freeway runs now; the old Camino Cabrillo next to it has since been overrun). Franklin Delano Roosevelt, the future President, was the first to drive across and open it. Unusual for the time, the bridge was built 110' high due to the steep depth and walls of the canyon, and is 916' in length with a main 450' span consisting of seven arches of 56' each plus supports. Originally partially wooden due to the redwood timbers used to structure the concrete forms, it was not retrofitted despite a minor fire in 1951 and finally a major fire occurred in 2004 within the columns where the wood still resided. Firefighters had to smash holes in the bridge sidewalks to extinguish the burning beams. A 2005 restoration, depicted at right (click for an 89K enlargement), cost $3.5 million and removed the wood, replaced the steel and repaired the broken concrete.

Also note the wooden railings at left, added as part of the "retro-retrofitting" project to approximate the former appearance.

[Pascoe St bridge and Washington St exit, 1948, 77K.] Washington St and the sharp turn down into Mission Valley. This was where US 80 diverged off to join El Cajon Boulevard and head east until the Alvarado Freeway was built along Camino del Rio; after that, this was Business Route 80 and later Business Route 8 (which ostensibly it still is; see Part 1).

This interchange was complex to construct for its time and involved several approach crossings, as shown in the 1948 picture at right (click for a 77K enlargement). Look for the little US 395 shield at lower left. US 395 is crossing Pascoe St in the foreground with the 6th Avenue exit branching off to the right and the Washington St exit in the background; this view is southbound on the reverse angle ascending the lip from Mission Valley into Cabrillo Canyon. Note that Pascoe St no longer extends across the freeway today.

[Construction of the Washington St overpass, 1947.] The wooden railings on the overpass are part of the original construction, as shown in the south-facing 1947 construction image at right (notice the enlargement of the wooden railing, almost exactly the same as the picture today).

[Mission Valley interchanges with US 395, 127K.] Approaching the junction with Interstate 8. When the Cabrillo Pkwy first opened in 1948, this was a somewhat intriguing ellipsoid interchange with Mission Valley Rd (the top image of two on the right; click for a 127K enlargement). This was before US 80 and modern I-8 occupied Mission Valley, and was originally constructed as a county road.

After the city and county of San Diego expanded Mission Valley Rd into the Camino del Rio/Alvarado Expressway routing with FAS funding, later designating it as US 80 officially, the old interchange became increasingly congested and was replaced with the 1960 expanded one (the bottom image at right).

The modern CA 163/I-8 interchange was finally rebuilt again in 1991, which remains the current one in use and the one depicted in my photograph.

[Friars Rd overpass, 1947.] Friars Rd exit after passing through Interstate 8, the last of the original overcrossings, although it has obviously been rebuilt. The original Friars Road bridge (then signed "Friar's Road") is in the 1947 picture at right, facing southbound.

CA 163 has a strange split alignment north of I-8 for the complex movements to and from the Interstate; the original lanes appear to be the centremost ones.

Entire original image (103.2KB)

The original Cabrillo Freeway ended just after Friars Rd and continued on as expressway and regular two-lane highway which was subsequently widened in 1950. In 1956, the grade-separated freeway portion was extended north with new interchanges at Genesee Avenue and Aero Drive, the former interchange reconstructed in 1970 and the latter interchange now destroyed by the construction of the Interstate 805 Jacob Dekema Freeway/Inland Freeway in 1972. This interchange here at Mesa College Drive was added in 1972 as part of the I-805 project to mitigate the loss of the Aero Drive exit.

Parallel to CA 163 from approximately this point north is Kearny Villa Rd. Until 1964, when the southernmost phase of the north US 395 freeway was initially completed, a partial expressway alignment continued north; most of this is under CA 163 asphalt and subsequent reconfiguration, but what of it does survive is subsumed under Kearny Villa Rd itself.

North of the southernmost Kearny Villa Rd exit, Kearny Villa was pulled to the east to Ruffin Rd and swing around CA 52; we will ignore this diversion and continue on 'straight' as if this picture and the next were directly connected since the closest thing to the original alignment is actually modern CA 163 itself.

The first of our military turnoffs is old Camp Elliott. Camp Elliott was a Marine barracks, originally named Camp Holcomb, formally designated on 14 June 1940 after Marine Corps Commandant Maj. Gen. George F. Elliott (10th, serving 1903-1910) and charged with west coast defence through the 2nd Marine Division and the Fleet Marine Force Training Center West Coast. It remained in service through the Korean War, and was finally relinquished to the city of San Diego in 1961. Here is a brief history of Camp Elliott. There is a Caltrans depot here now. Portions of Camp Elliott were placed on what used to be Camp Kearny, to be explained a little bit when we get to Miramar.

Coming back up to CA 163 and the second and final junction with Kearny Villa Rd from the freeway. CA 163 east of the junction is not part of old US 395; it was constructed as part of an Interstate 15 bypass project around what was then NAS Miramar (more presently) in 1982.

The US 395 freeway continues north of the CA 163 intersection, today as a "city street." This was US 395 until 1969, built in initial form in 1965 and subsequently upgraded between 1968 and 1970, and after US 395 was decommissioned became I-15 itself. (We can prove this because there are at least two surviving postmiles as of this writing. For the significance of what a postmile is, see the Floodgap glossary.) However, it passes completely through NAS Miramar, which is now NCAS Miramar, and could not be further widened as Caltrans lacked the right-of-way. The problem was literally circumvented by building a completely new alignment for Interstate 15 curving around the old highway, opened 1982, and relinquishing the entire old freeway with ramps intact to the city of San Diego. This is the first exit, at Harris Plant Road. Ironically, the modern I-15 alignment is still completely hemmed in by the base, but at least it's on a much wider easement.

The MCAS Miramar (old Miramar NAS) exit for Miramar Way, one of the few new signs placed. Miramar Naval Air Station started in 1917 with the formation of Camp Kearny, named for the famous General Stephen Kearney who had captured California during the Mexican-American War with his legendary Army of the West. (And now you know where all those Kearnys on those street names came from -- see Part 1. General Kearney had another US 395 connection; see the main exhibit, Part 2.) Camp Kearny was, militarily speaking, a bust; despite its $4.5 million price tag, it was barely used for three years during World War I and decommissioned in 1920. (This suited a young Charles Lindbergh just fine, who used the abandoned field to test-fly his new Spirit of Saint Louis before heading east. In fact, the Spirit of St. Louis was also locally built, by then-Ryan Airlines Corporation. Lindbergh's legacy on San Diego aerospace continues, as his name graces the airfield -- Lindbergh Field -- at the San Diego International Airport.) Briefly used for dirigible testing during the 1930s, Camp Elliott was built nearby in World War II and the camp rapidly expanded to accomodate the 1st Marine Air Wing. Formally dedicated as Naval Auxiliary Air Station Camp Kearny in 1943, with a parallel Marine detachment as Marine Corps Air Depot Camp Kearny, renamed Miramar, the two combined as Marine Corps Air Station Miramar in 1945. When the Marines moved to El Toro in Orange County in 1947, the base was redesignated as NAAS Miramar, but again fell into disuse (the city of San Diego was even offered the land for a single dollar, but refused).

Although some training facilities persisted into the 1950s, it was not until the Vietnam War that Miramar adopted its most famous role as a training ground for the Navy's air dogfighting elite. In 1969, the TOPGUN school was established and welcomed the first of its famous F-14 Tomcat fighters in 1972. The base maintained its reputation as the "best of the best" in Naval air squadron training well into the 1980s when the movie of the same name "Top Gun" came out with that no-talent clown Tom Cruise in 1985 (I have not forgiven him for besmirching Mission: Impossible). However, after years of prominence, base closure recommendations in 1993 shut down the El Toro Marine base to the north and relocated the Navy's fighter squadrons and Top Gun school to NAS Fallon in Nevada (since 1996), moving the Marines back home to Miramar. After nearly half a century, the Marines are back where they started and Miramar again the home of their West Coast air power. The annual Miramar Air Show was always one of Dad's favourites.

The closest continuation is little Kearny Mesa Rd, rather than continuing up Kearny Villa to Miramar Rd. There is a small impassible stub at the western jog that is close to the old connector to Pomerado Rd and later the freeway, but it is probably not original surface and is gated private property anyway.

Passing by the Navy Operational Support Center and Marine Corps Reserve Center, attached to MCAS Miramar which this routing skirts the eastern edge of.

Along this portion of old US 395/Pomerado Rd is the community of Scripps Ranch, part of the city of San Diego. Scripps Ranch is named for Edward Willis Scripps, a newspaper publisher and founder of the E. W. Scripps Company media conglomerate and the former United Press Associations news service (the latter as a direct competitive move against the Associated Press, and is today part of United Press International). Scripps' media moguling started with his founding of the Penny Press, now the Cleveland Press, after working for his older half-brother James on his paper, the Detroit News. From the Penny Press, Scripps founded or acquired over twenty-five additional publications to form his young empire, making sure to groom local talent and maintain local editors for veracity and community support. His methods were extremely successful but his riches were not enough to overcome his chronic health problems, so he bought 400 acres in San Diego in 1890 and finally moved into a house on his new ranch around 1900. Most of the territory actually went to his beloved half-sister Ellen Browning Scripps; E. W. took only 30 acres for himself. Delighted with the weather, he stayed there and conducted most of his business directly from the ranch until his death in 1926. Among Scripps' other local connections is the Scripps Institute of Oceanography on the University of California San Diego campus, opened with donations by E. W. and Ellen in 1903.

Portions of Scripps' former holdings are also part of MCAS Miramar, and Scripps was in fact responsible for the name Miramar (roughly "sea view"), which Scripps named the local mesa after the Archduke Maximilian's castle in Trieste, Italy.

Entire original image (123.5KB)

Alliant was formed in 2001 out of the merger of the California School of Professional Psychology and United States International University (which is the name I remember). USIU started as California Western University, founded in 1952 on 90 acres in Point Loma (now Point Loma Nazarene University, where I used to work and this server used to be housed [see the CA 209 exhibit]) out of the old Balboa Law College, later Balboa University, which was the first law school in San Diego when it was founded in 1924. In 1967, Cal Western University changed names to USIU and moved here to Scripps Ranch in 1968, leaving the California Western School of Law behind which separately moved to downtown San Diego in 1973 and severed its affiliation in 1975. USIU maintained multiple campuses throughout the USA and the world, consistent with its name. CSPP, for its part, was founded in 1969 with its first campuses in San Francisco and Los Angeles and expanded to San Diego in 1972 and Fresno in 1973. Today the unified university has approximately 3,600 students. This sign also depicts the affiliated Thurgood Marshall Middle School, named for the late U.S. Supreme Court justice and the first African-American to serve on it. (For the UCSD graduates in the audience, though, it will still always be Third College to me.)
