Finally we come to the continuation (and in this Part, the end) of the 1959 US 91/US 395/CA 18 Riverside Freeway, which we left in Part 14, which north of the Riverside Interchange is solely traversed today by Interstate 215. (For the numbering history of Interstate 215, rewind back to the beginning in Part 12.)
As originally designated, the Riverside Freeway ended at the former junction
with CA 30, which in those days was at
Highland Avenue, and we'll look at that exit which still exists. North of
that point, US 91/US 395 then and I-215 now continued/continues as the Barstow
Freeway, which "co-names" with the Mojave Freeway after rejoining with
Interstate 15 in Devore. More about that in Part 18.
Click the thumbnail at right to open a new window with a scrolling map showing Riverside and San Bernardino in 1947, 1957, 1963, 1969, 1974, 1977, 1984 and 1999. Flash 6.0 or higher is required.
As with the Riverside Interchange to the south (Part 14), the Riverside Freeway has its own large interchange in San Bernardino, although the San Bernardino Interchange was actually built first in 1958-9. At that time Interstate 15 started in San Bernardino, not in San Diego (Part 12), and US 91, US 395 and briefly CA 18 continued south from there as shown in the 1960 overhead sign above (click for a 45K enlargement); I-15 started at Interstate 10/US 70/US 99 (on the San Bernardino Fwy alignment west to Los Angeles) carrying US 91, US 395 and CA 18 with it. (This confusing mass of co-signage was undoubtedly one of the contributors to the legislation behind the Great Renumbering!) The first San Bernardino Interchange was a simple two-level interchange and had left exits, which we'll look at in this section; the present four-level stack interchange was built in 1972, still as part of I-15 and still using US 395 shields for continuity despite its 1969 truncation, later changed over to Interstate 15E and then I-215. Some of the damage to signs done as part of the changeover is still visible.
At the US 66/Fifth Street exit, the freeway added US 66 and US 66, US 91 and US 395 continued co-routed up to US 395's deviation in Hesperia. After the 1964 Great Renumbering, US 91 was struck from signage and US 395 remained officially alone with I-15 although for some reason US 66 persisted on signage despite not legislatively existing either. We'll discuss what happened to CA 18 in a moment. There is an anomaly in some documents that seems to indicate that the San Bernardino Freeway designation continued up to the Barstow Fwy name change along with the Riverside Fwy designation, but virtually no one refers to that portion of I-215 by that name nor in my humble opinion does it particularly make sense to do so, so I will not use that convention here. Upon reaching Devore, original I-15 continued with US 395 (and US 66, US 91) into the Cajon Pass until 1969, intersecting with old route CA 31 coming north on the so-called Devore Cut-Off alignment. In 1969, I-15 was swung onto the west bypass alignment, obliterating CA 31, and decommissioning US 395 in favour of I-15E, the ancestor of I-215. Remember, however, that I-15E was internally Route 194 on the Caltrans books (Part 12) and at least one example of this secret internal numbering still survives in the field.
Modern I-215 through San Bernardino is a frankly substandard freeway with southbound left exits, badly maintained asphalt and poor carrying capacity with infrequent shoulders, basically the original US 91/US 395 freeway with only token upgrades. We'll see that in spades in this section. Part of the reason for this strange design was, as we alluded to in Part 15, the railroad: the cost of building all the freeway interchanges to completely clear the railroad tracks parallel to the freeway was just too high at that time, so all movements simply shunted traffic east instead and avoided the railroad completely, using a smaller number of separate bridges that did cross the tracks to access the west side.
This had a significant negative impact on businesses and properties on the
west side of the freeway that suffered from the considerably reduced access
the obviously compromised design offered, and for decades the west side
of San Bernardino
complained publicly about the economic effects of being effectively cut off
from the highway. Only recently did funding and design approval come through
to improve this situation, and SANBAG (the
San Bernardino Associated
Governments) in association with Caltrans District 8, the Federal
Highway Administration and the City of San Bernardino now
have several plans on the books for much-overdue improvements
to this vital transportation corridor. Starting in Colton-Grand Terrace, the Mt
Vernon/Washington and Barton Rd interchanges will be preliminarily
reconstructed pending widening from the Riverside Interchange to the Orange
Show Road exit, just north of the San Bernardino I-10 interchange, at a cost
of approximately $1.4 million with work to start in approximately 2016 in
cooperation with the County of Riverside, the Riverside County Transportation
Commission, and the Cities of Riverside, Grand Terrace, Colton and
To the north, through San Bernardino proper, SANBAG is already at work on
adding a mixed-flow lane and carpool lane to both NB and SB carriageways
between I-10 and
Interstate CA 210, along with completing the
I-215/I-210 interchange with proper flyovers for all movements (this was an
aggravating deficiency with the current design; I'll discuss that when we
get to CA 30 and CA 210). The first phase (2007-9) will reconstruct the
5th Street/CA 66 (old US 66) bridge, widening it for the extra I-215 lanes
and replacing the left movements with a standard interchange for the first
time, with a price tag of approximately $25 million; the second phase
(2008-10) will widen the freeway from Orange Show Rd to near Rialto Avenue
to five lanes per direction, including a new Mill Street intersection, a new
Inland Center Drive bridge (already in progress), and widened Warm Creek and
Lytle Creek bridges; the third phase (2009-13) will continue the widening
up to the CA 259 "CA 30" interchange
with new bridges at 2nd, 3rd, 9th and Base Line Sts, a new CA 259 interchange
and sound wall/street improvements; and the fourth and final phase
(2009-13) will finish the widening through future I-210 and finally complete
the I-210 interchange. It's a lot of work, but this freeway needs it.
Finally, I-15's junction with I-215 in Devore is also slated for future
improvements through this very high traffic junction (over 160,000 vehicles
daily travel north on I-15 past the split, but 140,000 of those are on
I-15 south of it). This plan aims to make I-15 the primary lanes for the
merge instead of I-215 (a holdover from the US 91/US 395 days) to eliminate
weaving and lane shifting, and would ensure a full four lanes per direction
all the way from CA 60 to the southern end of modern US 395 in Hesperia,
with a possible truck bypass lane to cut down on truck lane shifting through
the new interchange. The project is still being designed and considered with
an estimated price tag of $200 million. If approved, construction would likely
occur around 2013.

Approaching the interchange, this time from WB I-10. Notice the twin movements
for I-215 coming off as a single ramp to separate into flyovers for the main
interchange stack. That was not the configuration of the original 1959
interchange, which I found pictures of in a very strange place:
Mission: Impossible television
series, specifically the 1968 second season episode
"The Town," where two clandestine assassins travel
from their disguised small-town base into Los Angeles to try to kill a
defector (more about that in the US 395
In Popular Culture section).
On their trek into Los Angeles the assassins travel along a road that can only be US 66 based on its control cities, through the Cajon Pass (a shot of this is in Part 18), down to Victorville and into San Bernardino along US 395, and exiting on I-10 towards Los Angeles. That exit is shown in the episode, with a screen grab at right (click the thumbnail for a 54K enlargment, along with a view of the present-day interchange from the same perspective). Notice how I-10 east to Redlands exits on a left exit, with US 395 continuing straight on and I-10 west on a standard ramp with distinctively large letters for the control city on the overhead sign.
One other thing to notice is the odd spacing of the shields. The I-10 East
Redlands overhead clearly has gaps where the US 70 and US 99 shields used
to go, and the off-center SOUTH above the US 395 shield probably indicates
the spacing was different before when it had a US 91.

Proceeding along the ramp (this picture was actually taken from the onramp
from Waterman Avenue that joins it), we can see visible marks on the last
set of signs and on this one. Besides the painfully obvious greenout covering
over a lane arrow, there are other subtle findings on these signs that I
have run through contrast enhancement/threshold gating to bring out (click the
thumbnail at right for a 49K enlargement). At the far left is a gap with three
rivet holes, which the threshold inset shows to have a rounded edge; this was
obviously a 2-digit Interstate shield and could only have been I-15. This is
particularly easy to see without enhancement on the next overhead in sequence.
Beside it is an I-215 shield, but under that is the edge of a 3-digit US
highway shield and even the right "horn" is barely visible, sticking out from
the right just under the red INTERSTATE. This could only have been US 395.
Entire original image (120KB)
We get our lane back here. The I-15 shield gap is really obvious on this one
even without tweaking the image. You can also see suspicious damage patterns
on the southbound signs where their US 395 shields were, and the other
giveaway is the "switching" word order -- it's I-215 SOUTH but NORTH I-215,
but back then it was US 395 SOUTH and I-15 NORTH US 395, keeping the
direction after the primary route on each exit movement.

down the southbound side in 1968, also shown in "The Town," we would see
this exit for Orange Show Rd and pullthru signage for EAST I-10 to Redlands
and SOUTH US 395 to Riverside. The large control city font for Los Angeles
appears again here on the advance overhead for west I-10. The present-day
exit is shown in the inset. Notice that by this time neither CA 18 nor US 91
were signed anymore.

Let's flip around and rewind on the southbound side to look at the left
exits. First is Base Line St.
Entire original image (112.3KB)
Left separation to Base Line. Compare this with the late 1960s postcard at
right from the northbound side (click for a 83K enlargement); notice the large
ramp crossing the northbound lanes, which is traffic coming back as
a left merge from H Street/Orange St, and Base Line St itself is the
larger bridge behind that, with the Base Line offramp further back still
and just barely visible. You can also see an Interstate
shield with two US shields under it; this was probably US 66 and US 395 by
that date, and there is also some distant signage in the background we will
talk about momentarily, so you may wish to keep that window open for a moment.
Entire original image (105.9KB)
The next major left from I-215 is 5th St. On this advance overhead sign, a
CA 66 shield on top of greenout covers up an old US 66 shield. Notice another
left exit to Base Line, this time from traffic coming in from CA 259, which is
also joining via a left merge.
Entire original image (117.4KB)
Finally, the left exit to CA 66, but this isn't 5th St; 5th is the bridge in
the background. Instead, this exit dumps onto 6th St, and to get to
5th even traffic bound for CA 66 needs to exit and make two right turns to
cross the freeway. No wonder the west side was angry.

Back on northbound I-215 approaching the old CA 30 junction. These newer
signs replaced the older set and IMHO were considerably poorly designed.
Entire original image (125.9KB)
Let's look again at the postcard above (reopen the window if you don't have
it open already). Compare this signage with the enlargement of the signage
in the postcard background: we can't see the shields, exactly, but we know what
they probably are. This was originally the CA 18 exit as shown on the 1969
map inset before the CA 30 freeway was constructed, and after CA 30 was built
it became CA 259 (but only recently was this signed), existing only to give
CA 18 traffic a freeway connection to Waterman Avenue and the continuation
north. See the CA 30 exhibit for more
We also know that US 91 was no longer signed by 1969, but US 66 anomalously
still was. Armed with this information, we can now make some fairly good
guesses about those signs in the distance. There are a pair of shields
on the left side, one with a faint blue hue and the other somewhat wider and
apparently all white, with a single direction over the two of them. Next to
that is a single shield with a single direction over that, and then some
indistinct words and another shield with a single direction over that, and
the rightmost two(?) overheads appear to be simply named exits (possibly
Base Line). Given what we know about how the route was signed, and comparing
it with the overheads in the introductory blurb, the signage most
likely goes I-15/US 395 NORTH, EAST US 66, and the exit to EAST CA 18.

Notice that CA 259 only handles eastbound traffic. Westbound traffic has to use
Highland Avenue (well, actually, there is a better route that probably neither
Caltrans nor the City of San Bernardino want you using: go up to University
Parkway, loop around, and catch WB CA 210 going south on I-215). I-215 swerves
west here as the SB CA 259 to SB I-215 connector snakes overhead.

Exit to old CA 30 west. Notice the somewhat more angular state route shield,
which is typical of older signage. A 210 shield has been greened out over the
30, but I don't care to reshoot this one either. I like old route 30. The
reason Highland Avenue is worse than University Pkwy in my opinion is all the
traffic lights and the nearby CHP station.
At this point, the Riverside Freeway now becomes the Barstow Freeway.

At Highland Avenue, there used to be this sign with a suspicious white NORTH marker, like the ones Caltrans uses for US routes. Hmm. Just thinking here. This sign came down with the rest of the CA 30 signage after TEMPORARY CA 30 was decommissioned.

End I-215 as "TO I-15 NORTH." Notice that it is I-15, on the overpass, that
crosses I-215 to become the right lanes of the highway; I-215 is in fact
the through route in this configuration and becomes the left lanes despite
bearing much less traffic. That's because I-15 was routed over
which was the minor route, and I-215 carried the three major routes of
US 66, US 91 and US 395. The route of the old CA 31 cutoff is shown in the
inset map at right (click for a 31K enlargment), showing the course of the
future Interstate 15 just before the designations were switched.
As we mentioned in the blurb, this interchange will be
significantly reconfigured in the future to make I-15 the primary and through
alignment (drat, since I usually approach this interchange on I-215).

Another demonstration of how I-15 is the "secondary" route is on I-15's
approach. Instead of merging smoothly into I-215, I-15 simply splits off
into ramps, another holdover of the old CA
31 cut-off configuration. The sign at right used to have a I-15 shield
under it but that was replaced by the current sucky retroflective version.

However, the original left overhead is still up, complete with a weathered
I-15 shield and a very obvious looking space and shield outline next to it,

with me and I'll refer you to an ophthalmologist immediately.
