State Route Numbering

[Jason Burke]

Hey there! I have an interesting trivia question for anyone out there:
I am under the impression that many of the numbers used on state highways
(that would be the little green signs, people) had their beginnings on old
mail route maps. I wonder then if it is a coincidence that Hwy 49 just
happens to run through the gold country... Or am I talking out of my ass
here... Is that where those numbers came from (at least the older ones)?

[Daniel P. Faigin]

There is actually no rhyme or reason to state highway numbers; I've been
studying them for a few year. Some are derived from old US highways. I guess
it is time to repost the folllowing:

California State Highway Routes

Last Modified 12/5/94

INTRODUCTION

The following is a listing of California State Highway Legislative Routes.
Note that the descriptions are condensed from their legal definitions; some
of these routes are unsigned or unconstructed (i.e., they exist only on
paper). Where possible, I've provided some historical information.

----------------------------------------
Subject: SOURCES

This information is derived from CalTrans maps, a history CalTrans wrote on
the Interstate system, the book LA Freeway (published by University of
California press), a 1958 Rand McNalley map of California, information gleaned
from my research and from the Urban Archives at Cal State Northridge (formerly
Valley State), the California State Highway Code, and contributions and
corrections from various net folk, including Gary Araki, Eric Ching, Duncan
Shaw, David Whiteman and others whom I cannot remember.

----------------------------------------
Subject: BACKGROUND AND EXPLANATIONS

As defined in the state highway code, there is no distinction between
"Interstates", "US Highways", and state highways -- they are all state
highways. Secondly, not all interstates are created equal. Some interstates
are what are called "chargeable", others are "non-chargeable". Let me explain
the difference.

The Interstate System was created by the 1944 Federal-Aid Highway act, which
authorized 40,000 miles nationally. California was initially allocated 1,938
miles. Later allocations in 1955 brought the total milage to 2,135 miles.
The 1956 Federal-Aid Highway act authorized an additional 1,000 miles
nationally; California received none of this. The 1968 Highway Act added
another 1,500 miles. Through later reallocations, remeasurements, and
various transfers (Howard-Cramer Amendment), the net total milage of the
42,500 national miles of interstate allocated to California is 2,311 miles.
This milage is called "chargeable Interstate". All of this milage is/was
eligible for construction with regular Interstate funds.

Section 139, Title 23 of the US Code allows for the designation of certain
highways as Interstate routes in addition to that which is "chargeable".
These highways are not eligible for regular Interstate Completion funds and
are called "Non-chargeable Interstates". They are all Federal-aid Primary
highways that meet the criteria for Interstate routes. They are signed as
interstates to provide continuity and connectivity for motorists and
truckers. There are two types:

139(a) milage are routes that already meet Interstate standards and can
be immediately signed as interstates once the proposed number is approved.

139(b) milage is designated as a future part of the system once Interstate
construction standards are met. It cannot be signed as interstate until
then.

----------------------------------------
Subject: HIGHWAY NUMBERING

In terms of interstates, there is a recommended convention for highway
numbering. When a state highway department wants to assign a number to an
interstate highway, they must get that number approved by AASHTO (American
Association of State Highway Transportion Offices), which usually enforces the
convention. This convention is:

One and two digit route numbers:

Odd North/South, lowest numbers in the West.
Even East/West, lowest numbers in the South.

Multiples of 5 are "MAJOR" interstates that typically go cross
country.

Three digit route numbers:

First digit odd Spur into metropolitan area (at time of route
adoption).
First digit even Spur around metropolitan area (at time of
route adoption).

Number mod 100 Route spurred off of.

For the older, Federal highway system (US-xxx), the convention is less clear.
It appears to be similar to the interstate convention, except that:

Odd lowest numbers in the East
Even lowest numbers in the North

There appears to be no rhyme or reason to the numbering of state highways.

----------------------------------------
Subject: STATE HIGHWAY LEGISLATIVE ROUTES, ANNOTATED

The following conventions are used in the annotations:
[Note:] General Note
[SHC xxx.x Freeway: route]
Portion designed by the state as part of the
California Freeway and Expressway System per
SHC Section 253. Note that this does not mean
the route is constructed to freeway standards;
rather, it was planned to be a freeway.
[SHC xxx.x Scenic: route]
Portion designed by the state as a scenic
route per SCH Section 263
[SHC xxx.x Histor: route]
Portion designed by the state as part of the
California Historic Parkway system, per SCH
Section 280.
[SHC xxx.x IRR: route]
Portion designed by the state as part of the
Interregional Road System Plan per SCH Section
164.3.

Now, the definitions of the various types of highways are as follows:

"Freeway"
A highway in respect to which the owners of abutting lands have no
right or easement of access to or from their abutting lands or in
respect to which such owners have only limited or restricted right or
easement of access. If, in the judgment of the commission or the
director, the public interest would be advanced thereby, a freeway, as
defined herein, may be denominated a "controlled access highway". In
all other respects, the "controlled access highway" shall be subject
to all provisions of this code pertaining to freeways. [SHC
Sect. 23.5]

"State highway"
Any highway which is acquired, laid out, constructed, improved or
maintained as a State highway pursuant to constitutional or
legislative authorization. [SHC Sect 24]

California Freeway and Expressway System
A statewide system of freeways and expressways and connections
thereto, creating a comprehensive system of access-controlled freeways
and expressways throughout the State. Within this system a "freeway"
is defined as a divided arterial highway for through traffic with full
control of access and with grade separations at intersections, while
the "expressway" is defined as an arterial highway for through traffic
which may have partial control of access, but which may or may not be
divided or have grade separations at intersections.[SHC Sect 250-252,
257]

California Scenic Highway System
Those portions of the state highway system which, together with the
adjacent scenic corridors, require special scenic conservation
treatment. [SHC Section 260]

California Historic Parkway System
Those portions of the state highway system that (1) were constructed
prior to 1945; (2) have been recognized by CalTrans or the Office of
Historic Preservation in the Department of Parks and Recreation as
having historical significance, including notable landmarks,
historical sites, or natural or human achievements that exist or that
occurred during the original construction of the parkway or in the
immediately adjacent land area through which the parkway currently
passes; (3) are bounded on one or both sides by federal, state, or
local parkland, Native American lands or monuments, or other open
space, greenbelt areas, natural habitat or wildlife preserves, or
similar acreage used for or dedicated to historical or recreational
uses; and (4) are traversed, at the time of designation and by the
department's best count or estimate using existing information, by not
less than 40,000 vehicles per day on an annual daily average basis.
[SHC Section 280]

Interregional Road System Plan
A system of roads or projects on which construction can be started not
later than June 30, 2000, that will provide the most adequate
interregional road system to all economic centers in the state. The
projects shall be on eligible routes identified and be located outside
the boundaries of urbanized areas of over 50,000 population as
designated by the most recent census of the Bureau of the Census,
except as necessary to provide connections for continuation of the
routes within those urban areas. [SHC Section 164.3]

SPECIAL NAMES

State highway routes embracing portions of Routes 280, 82, 101, 5, and 72, and
connecting city streets and county roads thereto, and extending in a
continuous route from San Francisco southerly to the international border and
near the route historically known as El Camino Real are known and designated
as "El Camino Real."

Ventura to the Torrance/Manhatten Beach area; continued as freeway
from the terminus of Rte 107 (Hawthorne Blvd) to Rte 5. I recall
seeing proposals for this showing pylons in the
ocean. Construction of this as freeway was killed around the same
time as the Whitnall Fwy, Rte 64. This remained designated as Alt
US101 (or US101A) until 1964.]
[Note: Officially named "Pacific Coast Highway" SHC 635]
[SHC 253.2 Freeway: from the Los Angeles-Ventura county line to Route

2 (a) from Rte 1 near Santa Monica to Rte 101
[Note: Planned in 1965 to be freeway from Rte 405 to Rte 101; right
now, there's only a stub as freeway that starts just before Rte
101. They could never get permission to build through Beverly
Hills (for the longest time, there were discussions about having
the freeway go underground through Beverly Hills). Of all the
freeways in the Southern California area that were never built,
the Beverly Hills Freeway (Rte 2) probably would have had the
greatest impact on both traffic volume and the surrounding
neighborhoods (not all of it for the better)]
[SHC 253.2 Freeway: from Glendale Boulevard to Rte 101]
(b) from Rte 101 to Rte 210 via Glendale and Wrightwood

near Mt. Shasta to Route 97 near Weed; and from Route 3 near Yreka
to the Oregon state line near Hilts.]
[Note: Approved as chargeable Interstate on 7/7/1947; the original
routing was along Rte 99, this was later changed to the current
Westerly routing]
[Historical Note: According to a book on the history of Buena Park,
there was a debate regarding the routing of Rte 5 through Buena
Park. Apparently there were three proposed routes each of which
were established as temporary highways while the freeway was being
planned, and there was even a AAA map published that showed all
three routes. Apparently one route was the site of the original El
Camino Real Highway, which thru Orange County went up roughly what
is now SR 57, and then went west on La Habra Blvd. Knotts Berry
Farm, which was then the Amusement Park as this was pre
Disneyland, wanted the route that went up Beach Blvd, SR 39.
Buena Park, itself, did not want to be divided by a freeway and
was opting for the Manchester route which is the current route.

[Note: This portion approved as chargeable Interstate on 7/7/1947; the
portion from Rte 101 to Rte 5 was originally to have been
designated as I-110, with I-10 sharing a route with Rte 5 between
the San Bernadino and Santa Monica portions of Rte 10. The I-110
designation was deleted as chargeable interstate in August 1965
and a designation of I-10 was used to the Rte 101 interchange.]

[Note: A 1965 planning map show this as freeway that, once it hits the
San Fernando Valley, continues along Balboa and Reseda, then

now the intersection of Mission Blvd and Rte 880, through Warm
Springs, up over Mission Grade, and then followed the existing
alignment of Rte 680. There are sections of Rte 680 that veer from

Before the completion of the Benecia-Martinez Bridge, the Hwy 21
alignment used Pacheco Blvd to get into Martinez, and then a Ferry to
Benicia. Rte 21 ended at the intersection of the old Mission Grade
Road and Mission Blvd. In the mid 70's after the completion of the
Rte 680 corridor, Rte 21 existed between a point at the north end of
the Benica Bridge, to the junction of Rte 80, which is now currently
Rte 680. The original signage of Rte 680 proceeeded using the current

Subject: NOTES ON PRE-1959 NUMBERING

It seems that in the 1959 or early 1960's timeframe, a massive renumbering of
state highways was done. Here are some notes on what it looked like pre-1959:

Los Angeles
US6 ran concurrent with US99 along San Fernando Road, and then turned
along the Harbor/Pasadena freeways down to San Pedro, and then
ran along PCH concurrent with US91 until the traffic circle in
Long Beach [David Whiteman notes that there is a book about
the history of the LA Freeway system that includes a picture
of the Harbor/Pasadena/Hollywood/Santa Ana freeway stack, with
the Harbor Fwy having the US6 designation, and the Pasadena
Freeway having the US66 designation (I would presume that the
Hollywood and Santa Ana Fwys were both US101).]
Sepulveda Blvd used to be designated as Rte 7.
Rte 11 (now Rte 110) followed its current route as 110 into Pasadena
concurrent with US6 and US66. It also appears to have been
Linda Vista Ave between Rte 134 and Rte 118 (Foothill Blvd)
Artesia Blvd used to be signed as Rte 14 (a number now used for the
Antelope Valley Fwy); Artesia is now Rte 91.
The Long Beach Fwy (now Rte 710) used to be signed as Rte 15. Between
signing as Rte 15 and Rte 710, it was Rte 7.
Rte 18 (see US91)
Olympic Blvd used to be signed as Rte 26.
Rte 35 ran from US60/70/80 (now I-10) along Puente Ave, Workman Mill
Blvd, and Norwalk Blvd.
US60 ran long what is now I-10 until Rte 71, and then picked up
Ontario Blvd. Take Business Rte 60 if you want to see old
US60.
US66 ran along Foothill Blvd and Huntington Ave and Colorado Blvd,
thence along Fair Oaks. Once the Pasadena Fwy was built, US66
was the Pasadena Fwy (Figueroa was US66A). It then
followed US101 to Santa Monica Blvd, following Santa
Monica to end at Ocean Avenue. There is a plaque at the point
where Santa Monica Blvd meets Ocean commemorationg the end of
Rte 66, the "Will Rogers Highway", "Main Street of the USA".
You can still drive much of 66 in CA today; parts are CA66,
CA30, the "National Trails Highway" between San Bernadino and
Barstow, the Business 15 and 40 through Barstow, and the
National Trails Hwy through Perth and Amboy, S of I-40.
US70 ran along the San Bernadino Fwy. Much of this was Valley Blvd.
Again, take the Business Rte 10 if you want to see old US70.
US91 ran along what is now I-15 from Las Vegas to San Bernadino and
on into Riverside, it then continued along what is now Rte
91 into Santa Ana, being co-signed as Rte 18. It then
continued along Lincoln Ave to Lakewood Blvd, Lakewood to
the traffic circle in Long Beach, and then along PCH to Rte
15.
US99 ran along San Fernando Road to the San Bernadino Fwy, along the
San Bernadino (concurrent with US60 and US70) to Indio,
following what is now Rte 86 to the border.
Pacific Coast Highway, currently Rte 1, used to be signed as US101A.
US101 was Ventura Blvd, the Hollywood and Santa Ana fwys
La Tijera Blvd to La Brea used to be signed as Rte 107, continuing as
Rte 107 as La Brea turned into Hawthorne and down Hawthorne.
Now, only Hawthorne is Rte 107.

Rte number basically unaffected by the renumbering were Rtes 134,
107, 118, 22, 39, 55, 71, 30, 39.

San Diego
Into downtown San Diego, US 395 ran along what is now I-15. In
downtown San Diego, it ran along the Embarcadero Fwy, now Rte
163. North of where 163 and 15 intersect there are a series of
parallel streets to 15 that were once US395, as well as a
portion of the 395 freeway that has since been converted to a
bicycle route (almost always desserted). This was the site of
the famous Cara Knott murder, an 18 year SDSU coed who was
murdered by CHP officer Craig Peyer.
US 101 ran along a route that is roughly what is now I-5. Portions of
the old 101 highway in San Diego that runs parallel to I-5
still have the US 101 signs up, and have the street names "Old
101 highway."
US 80 ran along what is now I-8

Rtes 75 and 94 appear to be unchanged.

San Francisco Bay Area
The Bayshore Freeway was Bypass US-101; on some of the signs, you can
still see some "green-out". The last of those signs are in the
Sunnyvale Area and near San Mateo.
US101 was El Camino Real and Monterey Road in San Jose.
Rte 5 ran along Skyline Blvd between Rte 1 and Rte 17. This is
currently approximately Rte 35, although parts of the original
Rte 5 alignment follow the current allignment of Rte 280.
Before 280 was constructed, Rte 5 began at the intersection of
Rte 9 and Skyline, proceeded up to the junction of Rte 92, and
then went over Crystal Springs Reservoir, and then turned
north following the existing portion of Rte 280 from the
92/280 interchange north to until where Skyline Blvd exits to
the left.
Rte 9 ran into Hayward from San Jose [The current signing of this
route is as follows: (a) From San Jose, Rte 237 (don't know
how far south down on 237, though), (b) East to Rte 880, (c)
North to Rte 262 (Mission Blvd), (d) North along Rte 680 (Rte
21 back then), (e) branched off at Mission Blvd, going north
(Rte 238), ending at Rte 92. For more information, see the
entries for Rtes 9 and 21.]
US 40 followed the Eastshore Fwy S (the Business Rte was San Pablo)
to the Bay Bridge
US 50 ran into Oakland, followed Foothill and McArthur Blvd to Bay
Bridge.
The San Francisco/Oakland Bay Bridge was US40/US50

Rtes basically unchanged include Rte 1, Rte 101 (Rte 101 was in the
area, but the original routing was that of the current Rte
82), Rte 24

Statewide
Rte 33 between Ventura and Taft was US399. US399 also ran between
Bakersfield and Taft. US399 came from Ventura and then made a
turn in Maricopa using the current Rte 166 routing.
US466 corresponded to Rte 46 from Paso Robles to US99, then along Rte
58 from Barstow to Bakersfield, and then concurrent with US91
beyond Baker
There was both a US99W and a US99E out of Sacramento. The routing of
US99W was from Sacramento to Davis (via existing 80), thence to
Woodland (via current Rte 113), thence following approx. I-5's
route to Red Bluff, where it joined US99E. US99E ran from
Sacramento, via approx. the routing of current I-80 to
Roseville, thence to Marysville via existing SR65, thence to
Yuba City, thence to Chico and Red Bluff via the current SR99.
Rte 299 used to be US299.
What is now Rte 14 was US6
US40, after Sacramento, went through Cisco and Trukee on its way to
Reno. Alternate US40 used to run from Dixon via Woodland, to
Yuba City to Marysville, and then through the Feather River
Canyon to US 395. Currently it is SR 70.
Rte 8 ran between Stockton and Mokelumne Hill. It is currently signed
as Rte 26.
If you take the old Business Rte 99, you're on old US99.

It is no coincidence that SR 49 runs through the Gold Country.
It is also no coincidence that a state highway sign on a post
(not on a big overhead sign) looks somewhat like a miner's spade.

This brings up a subject I'm still trying to track down. Rte 1 from
I-280 to Doyle Drive seems to also be called the Shore Line Highway.
There is such a CalTrans sign just north where it leaves I-280 as
Juniper Serra, just before the Brotherhood Way interchange. And I have
seen a similar sign in Marin near Mill Valley where Rte 1 leaves from
US-101. Does anyone know whre this designation coes from? Or, for that
matter, other such designations as Redwood Highway for US-101 north of
the GGB.

Cabrillo Highway, Pacific Coast Highway, and El Camino Real are
legislatively defined, and can be found in the Streets and Highway
Code, but I am unable to find any authority for the naming of any other
such highways.

Another one I've always been puzzled about is the Blue Star Memorial Highway.
As far as I can tell, this Highway is the onramp onto 280 south from El Monte
Road (or is it Magdalena? Been a while...). That's one short highway, but it
does have a classy sign.
