The Mass Grave is my grab bag of interesting incomplete surveys of routes long gone that don't merit separate entries of their own, particularly left-over signage or evidence of old signage that remains, or sometimes things that are just plain weird or bizarre related to a state highway's history whether vintage signs or not. Some of these mini-entries may graduate to full entries in the future, but for now, please enjoy them in miniature and keep your voices down in respect for others visiting the cemetery.

CA 7 photographed February 2005
CA 7 is the original signage for the Long Beach Fwy in Los Angeles, or what is now called I-710. This renumbering occurred in 1984, so it's not too surprising that a few remnants survive, although they pop up in a few unusual areas.
The thumbnail at right opens a new window with a scrolling Flash map of Los Angeles freeways (Flash 6.0 is required). Note how the Long Beach Freeway is signed CA 7 in 1984 (before the renumbering) and earlier, and only appears as I-710 in the final map section. (Prior to being CA 7 it was CA 15, but that introduced an obvious duplicate with Interstate 15. None of the old CA 15 signage is left.)
The most obvious evidence of CA 7 is on the bridge signs; this is only one
of many (I also saw them posted on NB I-710 @ Willow St and Florence Ave,
and I imagine there are others), chosen because it
demonstrates clearly its presence on modern-day I-710. This picture was taken
at great personal risk and the annoyance of other drivers on SB I-710 at
Pacific Coast Highway in the collector lane. To save your eyes and
my bandwidth, here is an enlargement
of the bridge sign at lower right, clearly showing both I-710 (on the
rear sign) and old CA 7.

This is an old-style postmile sign and old-style bridge marker, both still
present. NB I-710 at I-405 interchange, in the collector lane, mercifully
with no one behind allowing me some time for a clear shot.

One of the most baffling gaffes is this overhead sign at Floral Drive
and N. Ford Blvd. Despite obvious recent upgrades (based on
the new-style I-710 sign), the overhead street sign still says CA 7.
Incredibly, this was still up as of summer 2012.

CA 7's original routing went all the way to what is now I-210, and
Caltrans means to finish
the job. Look on the maps above for a wee little stub of CA 7 (and
just south of the present-day I-210/CA 134 interchange. This stub rams into
California Blvd going south, and comes off Pasadena Ave going north, signed
as access to I-210 and CA 134. However, immediately after getting on from
Pasadena Avenue, we see this bridge sign identifying the route as CA 7.

CA 14U "Unrelinquished" photographed May 2005
No matter which side you stand on regarding Governator Schwarzenegger's vigourous attempts to cut the budget, one thing is certain: the State of California wastes a freaking lot of money. Want proof? Here it is in a roadgeek friendly form: Route 14 Unrelinquished.
In basic terms, when an alignment is abandoned in California (normally after a routing has been moved or deleted), it doesn't just go away; Caltrans has to go through a legislative process called relinquishment where maintenance of the road is offered back to the city or county through which it runs, and the city/county then votes to accept it. Until then, even though the alignment is abandoned, it still carries a route number even though it's not a state highway anymore. To denote this state of bureaucratic limbo, a "U" for "Unrelinquished" is added to the route number; one example of this is CA 103 north of CA 1, which is not part of the legislative routing anymore, and thus is technically CA 103U because the state hasn't yet given (in this case) the city of Long Beach back the actual land the road is on even though the legislative definition of CA 103 no longer goes past that point.
Because the U basically marks the route for eventual legislative destruction, it would seem very silly to sign a route with Unrelinquished markers because why would you waste the money on manufacturing and putting up shields -- let alone custom-made shields with the "U" designation -- on a route you intend to dismantle anyway? Regardless, that's exactly what Caltrans did with CA 14U, an unrelinquished portion of the route's old Sierra Hwy alignment (Sierra Hwy being former US 6) running parallel to the modern CA 14 Antelope Valley Fwy in northern Los Angeles county. For those unfamiliar with it, CA 14 serves Lancaster, Palmdale and Mojave, all the way up to its termination at modern US 395; the freeway was built in segments between 1963 and 1975. However, obviously not all parts of the alignment were apparently relinquished, and that leaves us with a bizarre stretch of signs that to my knowledge have no similar peer anywhere else in the state. While I don't know when they were placed, they are obviously of recent vintage.
According to Google Maps, these signs all exist within Santa Clarita city limits, although portions of the alignment have already been relinquished (south of PM T26.8 at San Fernando Rd, old CA 126, is no longer 14U as of 9/02). There are no signs north of the intersection depicted (Friendly Valley Pkwy), so I assume it was relinquished past here as well. This makes it a logical starting point for us, and we'll U-turn at the light to go south.

there are no postmiles of any sort along the stretch I've photographed.

CA 31 and TEMP I-15 photographed March 2005
It can be argued that CA 31 was never really a route in its own right, merely a legislative stub until I-15 was built (in this case, between Corona and Rancho Cucamonga/Ontario, although at least one of my maps from 1974 seems to indicate that the stub at Devore that would eventually be signed I-15 was also at some point signed CA 31). It was not created as a route until 1964 when I-15 was already well on the books, and CA 31 would be deleted in favour of the Interstate a mere ten years later in 1974 (although signs remained up for a time until the Interstate was completed, thereby making them pointless).
The thumbnail to the right opens up a new window with a 64K slice of a 1976
map showing CA 31's alignment along Hamner and Milliken Avenues, co-signed
as I-15. (The Devore stub is at the top right.)
At the present-day CA 60/I-15 interchange in Mira Loma, we have several
interesting remnants of CA 31 and even TEMP I-15 which literally float right
in front of our face.
Entire original image (95.5KB)
As shown on the CA 126 sign above, Caltrans likes to recycle their signs
and prefers to alter them rather than make new ones if possible. Thus, when
that segment of CA 126 was decommissioned, Caltrans simply stripped the
button copy of the shield off, leaving tell-tale glue damage behind.
So is it also with this advance signage indicating the I-15 interchange, and
under optimum light can even be seen with the naked eye (around 8 or 9am was
when these photos were taken). Click the thumbnail at right for an 11K
enhanced high-contrast and threshold-gated image showing the old exit
right under the "new" button copy -- Hamner and Milliken, and a 31 shield.

As we approach the Mira Loma interchange, built in 1986, we find several more
interesting pieces of evidence. Keep the overhead signs in this particular
shot in mind, as we will be looking at them segment by segment.

The most high-yield part of the interchange signage is the centre plate,
where the morning
sun striking it shows a designator (probably TEMP), an Interstate shield,
and Norco, Corona, NEXT RIGHT. Click the thumbnail at right for a 32K

A Route 31 shield appears on the left part of the overhead sign also, although
its damage pattern is a bit more worn. Next to the Hamner Ave/Milliken
Ave text is a faint area of glue damage showing a miner's spade and the
digits 31. Unlike the other enhancements, however, this one required a lot
of contrast boost to bring out (click the thumbnail at right for the
high-contrast/threshold-gated image). The miner's spade, indicated by the
long green arrow, was easy to illustrate, but the digits are a lot fainter
(indicated by the two short arrows). Crossing your eyes or stepping back
from the monitor helps a little.

is indicating the exit for Hamner Ave and Milliken Ave, just past the I-15

This is, of course, because something used to be there. The most obvious
to the naked eye is another Interstate shield and (presumed) TEMP
marker, but on the high-contrast view, a miner's spade appears. I ran the
image through the threshold-gating filter in Photoshop and was able to
isolate the "3" in Route 31 from it, but even obscenely high amounts of
threshold boost could not generate enough contrast to pop out the "1".

appears in relationship to the other components. Click the thumbnail for

US 60 photographed May 2005
Modern-day CA 60 (compare with CA 91, also on this page), which runs between the East Los Angeles Interchange and Beaumont, is the remnant of US 60 in California. Unlike some US routes that were chopped down with the rise of the Interstate system (US 91, for example), US 60 survives nearly intact outside of California, running from Quartzsite, AZ to Newport News, VA and retaining its preeminence as a (now almost) transcontinental route. Its destruction in California was probably because of the multiple multiplexes (say that five times fast) of US 60 and I-10 (old US 70, parts old US 99) along their respective courses; rather than preserve the potentially confusing multiplex signage, it was simply chopped off at the ankles, as it were.
Nevertheless, at the Beaumont interchange, the US 60 shield is still up, ill-covered by a CA 60 greenout plate (enlargement at right). Note how the original US 60 shield does not have button copy. Much of the US 60 expressway between Beaumont and Moreno Valley is still more or less in its original form, making it a fascinating trip back through time. Drive carefully, however, as the Badlands route is very substandard with respect to curves, grades and shoulder space.
Continue on to the US 91 entry for some maps showing the Riverside freeway
sign changes through time.

CA 65 photographed October 2005
CA 65 is a major state arterial in central and northern California, split into a southern half between Bakersfield and Exeter, and then from Roseville (outside Sacramento) to Marysville. The modern CA 65 in Roseville is constructed on a freeway alignment between Interstate 80 and Lincoln, but the old CA 65 was routed on Riverside Avenue down the main city centre. A postmile still survives a mile or two north of I-80, on the southbound side.
Dan Faigin mentions that
CA 65 was routed on US 99E, but it also seems that it was routed on US 40 as
there are Historic US 40 signs all over Riverside Avenue.

US 91 photographed April 2005
Like CA 60, CA 91 is the ghost of a mightier highway long since decomissioned in this state. Modern-day CA 91, which runs between Riverside and Gardena, is the remnant of old US 91 in California. US 91 today runs between Brigham City, UT and Idaho Falls, ID, a faint shadow of its former self as US 91 ran originally from Long Beach, CA all the way to Sweetgrass, MT and the Canadian border. Modern I-15 today carries much of the rest of the routing.
The thumbnail at right opens a new window with a scrolling Flash map of Inland Empire freeways (Flash 6.0 is required), as referenced in the US 60 entry above. Notice the US 60 and US 91 freeways in the San Bernardino/Riverside area from 1947 to 1963, and their subsequent resignage as CA 60 and CA 91 (ATGR), respectively, in 1965.
Again, this mini-exhibit depends on the fact Caltrans reuses a lot of their
signage; this likely suspect seems to date from the original US 91 freeway,
built 1957 to 1961, and stands at the modern Tyler Street/CA 91 interchange
south of the freeway in western Riverside.
Entire original image (126.9KB)
When we get up close to the sign and the light hits it,
again we see the ghosts of glue damage, but the clue that this is probably
from the US 91 days is right in front of us: the control city is still
listed as Long Beach, which was true before the Great Renumbering, but wrong
now. On the 72K high-contrast view (click the thumbnail to the right),
we also see the ghosts of two control cities above it, San Bernardino
and then Riverside, as well as a "Freeway" legend behind the current CA 91
shield, which was typical signage for some of the older freeways in this
area (old US 395 -- now I-215
-- has a sign like this
near the Columbia Avenue interchange in northern Riverside).
None of this is as incontrovertible as, say, a big fat US shield pattern,
but it still makes for interesting conjecture.

US 99 photographed October 2005
Who doesn't know US 99? This is one of the big ones, the highway everyone's trying to travel when they're not frolicking on US 66. If you've been hiding in a hole for the last half-century, US 99 ran from the Mexican border south of El Centro, CA, through San Bernardino and Los Angeles, then through Bakersfield and Fresno, and into Oregon and Washington states pretty much along the course of Interstate 5 to Portland and Seattle into Canada. Its receiving highway in British Columbia is still BC 99, and most of the leftover alignments in all three states are still signed as OR 99 or WA 99, or in this case, CA 99. CA 99 still serves Fresno along what is the largest of the old 99 alignments, leaving Fresno the largest city in the United States not served by an Interstate as of this writing (I-5 runs on a bypass alignment considerably further west).
All that to say that when you find a US 99 shield in the wild, it's a big thing; here's two (and another two on the northbound side), at Atwater, improperly covered with state shields a la US 60 above.

CA 118 photographed February 2007
CA 118 today is a major freeway between eastern Ventura county and Sylmar (at Interstate 210), plus a local arterial for points west to its terminus at CA 126 in Saticoy. An unconstructed portion was supposed to head east of Sylmar partially down I-210 and then west at Sunland Blvd towards unconstructed CA 249 (approximately where LACo N3/Angeles Forest Hwy runs now), probably along Big Tujunga Cyn Rd. This is unlikely to ever get built, by the way.
Before all that, however, CA 118 actually went far south of Sunland
along Foothill Boulevard (parallel to I-210) to terminate at US 66 in
Pasadena; I-210 technically replaced CA 118 with the 1964 redesignation,
although much of the
old highway persisted well into the 1970s. This former routing can be seen
in the 1957 map at left, including the old Foothill Freeway (which still
survives, not to be confused with I-210 itself, which is the new
Foothill Freeway -- see Old Highway 30).
For this reason, it should not
be surprising that this sign showing the old routing on Foothill still stands
in Sunland Park, just east of the Interstate.
[Or rather, it used to - as of 4/2010, this sign is gone. I will keep
the photographs up here as a memorial, since I rather liked it.]
Entire original image (131.5KB)
Notice, however, that it is 1) not button copy -- instead using the old
plastic reflectors -- and 2) using the older black-on-white shield style
that has not been in service since the 1964 renumbering.
Entire original image (80.1KB)
There is no date code on the back, just the panels holding the reflectors
in. It is the only piece of signage for old CA 118 that I have found in this
area, but I imagine it was left alone
since the real CA 118 is only a few miles north.

CA 163 (Old) photographed November 2005
No, not that CA 163 -- the first one. As defined in 1964, old CA 163 ran from Lacy Street and Avenue 26 along Ave 26 to Interstate 5 in Los Angeles (an old stub, apparently, of US 99). This lasted for only a year and I have never found it on any maps, although Dan Faigin has the legislative history.
So, credit where credit is due to the sharp-eyed Stan Konar, who wrote in one fine November day to tell me that old CA 163 lives, and live it does -- here's a bridge sign on SB Ave 26 showing it (sadly defaced), along with an(other) anachronistic reference to CA 11, or modern CA 110, which it crosses.

San Diego. That remains CA 163's present designation to this day.

CA 164 "CA 19" photographed February 2007
CA 164 today is a little known (and almost completely unsigned) route between Pico Rivera and Sierra Madre along most of Rosemead Boulevard. "But, wait!" I hear you cry. "This is Route 19!" Well, actually, no, it's not. In fact, this is one of those rare circumstances apart from multiplexes where the legislative route number no longer matches the signed highway, and was actually introduced with the 1964 renumbering that was supposed to eliminate such inconsistencies!
The reason why CA 19 remains over the entire route is because it in fact did possess the whole route between Long Beach to US 66/Foothill Blvd in Sierra Madre before the 1964 renumbering (although apparently over San Gabriel Blvd just a couple blocks west). Unlike many deleted or altered route numbers where the signage eventually caught up with the route number on the books, this never happened for CA 19. Today, CA 19 ends internally at the otherwise nondescript Gallatin Rd in Pico Rivera, and CA 164 continues north from there on Rosemead Blvd, but not on the signage where the signed end of CA 19 was and remains here, now at I-210.

CA 195 photographed July 2005 and July 2008
This exhibit has been greatly expanded in the Old CA 195 section. These older images remain here for posterity.
Old CA 195 is one of those ignominous routes to die a painful death twice,
first at the hands of US 95,
and then at the hands of the CA 86 expressway
(current CA "86S" Expwy). CA 195 was first signed in 1934, replaced by US 95
in 1940, and then reincarnated by 1963 between CA 86 in
Oasis and US 60/US 70 (soon to be I-10), as shown in the 1967 inset
map on the right. The "Mecca/Twentynine Palms" exit on present-day
I-10 is the former northern terminus. What most people don't know is that
this was actually a major routing during the very early days of the state
highway system, for it was the original routing of US 60 through southeastern
Riverside county to Chiraco Summit prior to the construction of the later
and current route ca. 1937.
