The first leg of our US 395 tour starts at its old terminus in San Diego, which was first signed in the middle 1930s. Its history within San Diego county is rather complicated and has multiple realignments and shifts which we will point out as we go along.
San Diego, California is the USA's eighth largest city with a population of 1,223,400  (estimated 1,256,951 ), and California's second largest. Inhabited in antiquity by the Kumeyaay Indians (Diegueño), whose name graces Interstate 8 as the Kumeyaay Highway and who continue to live in the region and on nearby reservations, the region was originally dubbed San Miguel (Saint Michael) by Spanish explorer Juan Rodriguez Cabrillo who first explored the region for Spain in 1542. (Cabrillo gives his name to the modern Cabrillo National Monument in Point Loma, and part of old US 395 [now CA 163] is the Cabrillo Freeway.) The roots of what would become the modern city, however, are generally acknowledged as starting with the foundation of the famous Mission San Diego de Alcala in 1769 (first as the Presidio de San Diego by Gaspar de Portola; it was consecrated to the Catholic church by Fr. Junipero Serra and later moved inland), making San Diego California's oldest city and as such the seat one of California's original counties in 1850 with a population  today of 3,051,280. The Franciscan mission building, once the largest in California, is a tourist attraction today and we will pass by and look at it in Part 2.
The name of the mission comes from San Diego Bay, christened in 1602 by Spanish explorer and surveyor Sebastián Vizcaíno after the Franciscan saint Didacus of Alcalá (rendered in Spanish as «San Diego de Alcalá de Henares») whose name graced Vizcaino's flagship. San Diego became the capital of Alta California y Baja California after Mexico's independence in 1821, but faded into a small village by the 1830s and lost its township in obscurity. Not until the California gold rush of 1848 would the small village revive itself, swelling by thousands and becoming large enough to merit a terminus on the transcontinental railroad in 1885. The modern city was reincorporated in 1886.
As someone who grew up in San Diego since age six, I think it fully deserves its reputation as "America's Finest City" thanks to its wonderful climate, its big city services with a small city feel, and its gentle terrain and beaches. There is also a significant Naval presence in the Bay; San Diego is home to the largest naval fleet on the planet as of this writing, including the supercarriers USS Nimitz and USS Ronald Reagan, and multiple submarines and medium-class vessels. The Navy has been a constant presence in San Diego since 1907 when the Naval Coaling Station was first established in the harbour.
The major remnants of US 395 in San Diego county today -- note that this is not an exhaustive list -- include what is now CA 163 (the old US 395 freeway); Market Street, El Cajon Blvd and Fairmount Avenue; portions of Murphy Canyon Rd, Kearny Villa Rd and Pomerado Rd; modern county highways S14, S13 and parts of CA 76; and parts of I-15, Centre City Pkwy and Old Highway 395. Most of US 395's final routing still persists and remains an important local artery, even after being cut down in favour of I-15 in 1969. Interestingly, US 395 was one of the few US highways to survive the bloodletting of the California Great Renumbering in 1964 -- I-15 was only intended to go to San Bernardino, which will be apparent on the supplemental maps when we reach that point. Even after US 395's legislative evisceration, the highway remained signed in San Diego county well into the 1970s.
US 395 had two major phases in its lifetime, which for simplicity we will refer to as pre-1950 and post-1950, although the actual dates during which alignments became truly part of the routing may vary a couple years in either direction. Because of these large shifts in routing, we will (where possible) attempt to traverse them simultaneously. Most of the pre-1950 alignment is still very easy to find with a little detective work. All of old US 395 from Temecula to San Diego is part of old Legislative Route Number 77, defined in 1931 (California's former method of road alignment tracking). Since US 395's history is tied to the LRNs, we will mention them as we come to them despite their being defunct since the Renumbering.
Each of the alignments we will travel are accompanied by map-backed
evidence. Click the thumbnail at right to open a new window with a
map showing San Diego in 1934, 1935, 1937, 1942, 1947, 1957, 1965, 1974,
1984 and 1999.
CA 71: Linda Vista Rd
Before there was US 395, there was CA 71, which today has been cut down also by Interstate 15 encroaching on its turf and remains only a shadow of its former self between Corona and Pomona. At its greatest extent, however, CA 71 ran from San Diego at US 101 (in those days along Morena Blvd while the "new" Pacific Hwy alignment was being constructed), also along what was then LRN 77. The change in signage seems to have occurred in 1934, because on the Gousha comparisons to the right CA 71 is still shown in 1934 and in 1935 US 395 is on Linda Vista Road instead. Note that state highway still extends down from there, but this appears to be the old routing of US 101 (now bypassed by Pacific Highway and today Interstate 5), not any old routing of US 395. We start here on old US 101 on Morena Blvd, as we cross a reference landmark we will come back to, the San Diego River.
We will see more of former CA 71 starting when we get to Riverside county in

Our starting point is northbound from the Interstate 8 Morena Boulevard exit.
I took this picture looking back at the interchange
that has nothing to do with US 395 just to mess with the
minds of the various dopes in the roadgeek community who think Caltrans
couldn't make a decent sign because of their (undeniably stupid) 1970s
practise of gluing reflective buttons onto their perfectly good earlier enamel
signs, which then turned grimy and left a lot of ugly and dirty signs out there
today. This is one of the old enamel signs that was not so defaced, and as you
can see has weathered perfectly well and better than the retroflective crap
that Caltrans and every other state DOT is using in their present
installations. So there.

The San Diego River is the channel responsible for many of the lakes in
Diego county, which were formed by damming either the river itself or one of
its many tributaries and watersheds (such as El Capitan Reservoir and
Lake Murray). In its far western section here, it is an estuary, considerably
widened by later dredging in Mission Bay; it is approximately 52 miles long
from its headwaters near Santa Ysabel to the coast. It also runs through
Trails Regional Park, the sixth-largest municipal park in the United
States (and the largest in California) at 5,800 acres, where it is dammed by
the centuries-old Old Mission Dam built to provide irrigation for the Mission
San Diego de Alcala.

The letters do not have the plastic reflectors actually incorporated into

in the wild.

Vista over USD from Linda Vista Rd. The University of San Diego is a private
Roman Catholic university established in 1949 as the San Diego College for
Women, followed by the San Diego College for Men and the School of Law in
1954; the modern university was formed by merger of the schools in 1972 and
has a student body today of 4,962. There is also a personal link, as the
Dean of Admissions while I was in high school was the father of a friend of
mine (despite the amusing fact she and he were Lutheran). The university is
also affiliated with the University of San Diego High School, which I remember
playing in academic bowl competitions. Although it is nominally Catholic, the
university is no longer administered by the Diocese of San Diego, although the
Bishop of San Diego retains a permanent seat on the administrative board.
The eye-catching blue domes in the background are part of Immaculata Parish Church, which is on the Alcalá Park grounds but not part of the University.

his particular brand of 'progressive' educational methods; that school, also
named Francis Parker School, was the model for this one. Despite its close
proximity to USD, it bears no religious affiliation.

responsible for many of the freeways built in San Diego, including US 395,
as well as the one named after him.

Linda Vista Rd no longer directly connects to old US 395 anymore (or, for that
matter, CA 71) due to the reconfigurations introduced with I-805's
construction. The rest of it is under later asphalt, so we will consider us
to have "merged" with old US 395 at this point. We'll be coming back here

US 395 in Downtown San Diego (1935-1969)
In 1934, the Division of Highways changed the routing of LRN 77 to start in downtown San Diego with US 80 (which is now superseded, for those unfamiliar with California road history, by Interstate 8). Initially both highways started here at what is now the corner of Park Boulevard and Market Street, but was signed then as 12th St and Market. In those days US 101 (now modern Interstate 5 south of Los Angeles) came east on Market and went south (straight ahead on this view) along 12th, so US 80 and US 395 started here and from our perspective go north behind us.
Note that the 1934 date is at odds with the 1934-5 map comparison we showed under CA 71 above. This is best explained by keeping in mind that the ACSC was doing signage in those days, not the Division of Highways, and the Inland Route along old CA 71 was well-established. Therefore, as a transitional measure, it would make sense that US 395 would have been signed there at least briefly despite not being the state-recognized routing.
Entire original image (115.1KB)
By 1943 US 101 was pulled west to the Pacific Highway routing and US 80 and
US 395 went with it, to the corner of Market St and Pacific Highway as
illustrated in the 1957 map inset to the right (click for a 63K enlargement).
This intersection was later reconfigured and then overrun
by subsequent construction such that the intersection is
now represented today more or less at the corner of modern Harbor Drive and
Pacific Hwy. Modern Market St starts at the traffic light in the background.
US 395 would maintain its terminus here for the remainder of its lifetime in
We proceed east, ignoring the turn for 'historical authenticity'.
As a parenthetical note, until the early 1940s westbound US 80 actually continued north along US 101 to Barnett Avenue, diverging there to Rosecrans St and south to Point Loma where it terminated at the Cabrillo lighthouse. The majority of this ancient alignment is part of CA 209, which is now also decommissioned, but may not have ever been actually signed as US 80 at any point.

Fourth and Market, and the Gaslamp Quarter.
The Gaslamp section of San Diego in the late 1980s and 1990s
a significant redevelopment project, transforming it within a few years into
a popular social section. Starting with daring commercial ventures such as
Horton Plaza and the famous downtown line of the San Diego Trolley, a
large number of shops, bars and restaurants
(even an enormous Pacific Theatres cinema) have now come to roost and
compete for night life bucks.

two-way, we would have turned left and gone north towards Balboa Park, but

Thus, we head northbound on Eleventh Avenue to continue the routing.
Between 1942 and 1948, CA 94 (San Diego's major southern east-west artery), which originally ran on Broadway, moved south to Market St and was then cosigned with both US 80 and US 395. As the CA 94 freeway was constructed in stages during the late 1950s and early 1960s, it was connected to F and G Streets as it does today, and then came down on 10th/11th to Market as shown in the 1969 map inset at right, shortly before US 395 was decommissioned in San Diego. My 1972 map shows this stretch signed as CA 163, but CA 94 was also signed, and I personally remember old-style white CA 94 shields persisting well into the 1980s.
The 1969 inset shows another interesting irregularity; CA 94 and I-5 were
apparently cosigned through the downtown S-curve. This can't have persisted
for very long and may have been a map error.

I do remember that
CA 163 markers did exist on this stretch after US 395 was decommissioned here,

Entering Balboa Park along old US 80 and US 395. Balboa Park is
the city's primary park space at 1200+ acres, which
houses many attractions in San Diego including the fascinating
Reuben H. Fleet Space Theater and Science Centre and, of course, the
world-renowned San Diego Zoo. First established
in 1868, Balboa Park is another San Diego landmark
named for an explorer; in this case, it is Vasco Nuñez de Balboa, who
was the first European to see the Pacific Ocean crossing Panama in 1511. The
name was applied in 1910 to what was originally called simply City Park.
Park Blvd runs along the lip of Powderhouse Canyon, pejoratively named in 1885 after the ammunition and gunpowder depots maintained by the residents of what was originally Slaughterhouse Canyon (and named for the same), and today one of the park's three major transit conduits. The boulevard shares Powder House Canyon with Florida Drive, which sits nearly at the bottom. Balboa Park's other major transit viaducts, natural canyons all, include Switzer Canyon, inhabited by modern Pershing Drive and the site of the aborted Switzer Canyon Freeway [CA 171]; and Cabrillo Canyon, which we'll see in Part 3.

And speaking of which, here's the

One of the world's largest and most highly lauded
zoos with over 4,000 animals representing some 800 species, it covers 100
acres within Balboa Park and is operated by the non-profit Zoological Society
of San Diego (although its assets and the ownership of the animals rest with
the City of San Diego). Its membership numbers over a quarter-million. The
Zoological Society also operates the 1800-acre Wild Animal Park near Escondido
and the Conservation and Research for Endangered Species, founded in 1975 and
dedicated to endangered and rare species preservation. Notable for its
progressive use of open
air enclosures and cageless exhibits, it also has the largest population of
Giant Pandas outside of the People's Republic of China.

More modern retro-signage as we cross the new CA 15 freeway, which one day
will be signed as an extension of Interstate 15 to the north. Until 1969
this was all CA 103, which ran along 40th Street instead from its terminus
at US 395 to the north; after Interstate
15's extension along US 395, the eastern routing down Murphy Canyon that
CA 103 took over from old US 395 (we'll
look at this in Part 2) was chosen for the
new Interstate because the
Cabrillo Freeway was not Interstate-grade and not upgradeable (thus
orphaning it as state highway, becoming CA 163).
South of El Cajon Blvd, CA 103 continued along 40th Street and Wabash Boulevard to CA 94 and ultimately US 101/I-5; this was, of course, not part of US 395. The CA 15 freeway was opened in stages; Wabash Boulevard was already more or less freeway at the time of CA 103's demise, but the remainder of the freeway was not constructed until the late 1990s and opened in 2000. Despite the community opposition originally, I think the upgrades have greatly improved the neighbourhood. The portions of 40th Street that were not obliterated still survive in discontinuous sections, but were never part of US 395 either.
