From Route 1 in Santa Monica to Route 5 near Seventh Street in Los
Angeles.
|
 In 1963, this segement was defined as "Route 1 in Santa
Monica to Route 105 near Soto Street."
In 1968, Chapter 385 changed the definitions of Route 105 ("from Route 5
to the junction of Route 110 (now part of Route 10) and US-101") and Route 110
("from Route 105 to the junction of Routes 5 and 10") from their former stub
routes in downtown, creating the present day I-105 routing. At this point, the
definition of Route 10 was changed to "Route 1 in Santa Monica to Route 5 near
Seventh Street in Los Angeles", and US 101 was changed to start at "Route 5
near Seventh Street in Los Angeles".

  The segment was LRN 173, and was defined as part of the state
highway system since 1933. Before this was reserved for the freeway, this was
Route 26 and ran along Olympic Blvd. The McClure Tunnel was originally part of
Olympic Blvd, although as part of US 101A.
![[Reece at 405-10]](images/reece.jpg) The I-405/I-10 interchange was designed by
Marilyn Jorgenson Reece, who was the first woman in California to be registered
as a civil engineer. She died in May 2004. A South Dakota native who earned a
bachelor's degree in civil engineering from the University of Minnesota in
1948, Reece moved to Los Angeles with her parents shortly after graduation. The
same year, she went to work for the State Division of Highways, which later
became Caltrans, as a junior civil engineer in Los Angeles. In 1954, after six
years of required experience to sit for the Professional Engineer's Exam, Reece
became the state's first fully licensed female civil engineer. In 1962, she
received the Governor's Design Excellence Award from Gov. Pat Brown for the San
Diego-Santa Monica freeway interchange. Shortly after, Reece became the
Division of Highway's first woman resident engineer for construction projects.
The three-level San Diego-Santa Monica freeway interchange, which opened in
1964, was the first interchange designed in California by a woman engineer.
Reece told The Los Angeles Times in 1995 that she put her "heart and soul into
it" and that she designed the interchange with aesthetics in mind. "It is very
airy. It isn't a cluttered, loopy thing," she said, adding that specifications
to keep traffic moving at high speeds necessitated the long, sweeping curves.
The image to the right, excerpted from One Hundred Years of Progress,
shows Reece and Thomas McKinley. However, the book referred to Reece as an
Associate Engineer, with McKinley as a Resident Engineer, but did indicate that
Reece supervised the I-405/I-10 interchange project. The view in the photo is
looking N from what is roughly the National offramp on the I-405; you can see a
sign for the Route 26 Olympic Blvd NB offramp that was removed as part of the
project (likewise, the SB National offramp was removed)

This portion is named the "Santa Monica Freeway"; the first
segment opened in 1961 and the freeway was completed in 1966. It was named by
the State Highway Commission on April 25, 1957. The name derives from the
western terminus of the segment in the City of Santa Monica. The name Santa
Monica may have been applied by the second Portolá expedition on May
4, 1770, the day of holy Monica, mother of Saint Augustine. It appears in 1839
in the land grant San Vicente y Santa Monica, on which the modern city was
founded in the early 1870s. Sierra de Santa Monica was recorded in 1822.
The portion of I-10 within the city limits of Santa Monica is named the
"Ricardo A. Crocker Memorial Highway". This segment was named in memory
of Santa Monica Police Officer Ricardo A. Crocker, a Major in the United States
Marine Corps, who was killed by a rocket propelled grenade explosion on May 26,
2005 while conducting combat operations against enemy forces in Iraq. Ricardo
A. Crocker was assigned to Detachment D, Third Civil Affairs Group, attached to
the Fifth Provisional Civil Affairs Group II MEF and had previously served in
Operation Iraqi Freedom II with the Third Civil Affairs Group from February
through September 2004, and was redeployed to Iraq with the Fifth Provisional
Civil Affairs Group in February 2005. At the time of his death, Ricardo A.
Crocker, known as "Rick," was 39 years of age and a 10-year veteran of the
Santa Monica Police Department. Ricardo A. Crocker held the rank of Captain in
the United States Marine Corps when he was hired by the Santa Monica Police
Department on July 21, 1995, subsequently being promoted to the rank of Major
in the Marine Corps. As an Officer for the Santa Monica Police Department,
Ricardo A. Crocker served in uniform patrol and was a member of the Crime
Impact Team and Special Entry Team, serving as the primary emergency medical
technician for the Special Entry Team, and was a rifle team member and rifle
instructor. While in his final assignment to the Police Activities League,
Officer Crocker made an indelible impression on the youth of Santa Monica by
teaching preparatory courses for the Scholastic Aptitude Test, leading the book
club, and implementing hiking and camping programs that exposed these youth to
his two passions: education and nature. Ricardo A. Crocker was an excellent
officer and ambassador for the Santa Monica Police Department as well as an
excellent protector of the community; was a consummate caring professional who
represented the highest standards and traditions of law enforcement and the
Santa Monica Police Department. Named by Senate Concurrent Resolution (SCR) 20,
Resolution Chapter 94, on 7/12/2007.
The segment between I-405 and Route 110 is named the "Rosa Parks
Freeway". Rosa Parks (born February 4, 1913, in Tuskegee, Alabama) is
considered the "Mother of the Modern Day Civil Rights Movement". This fame
started when she was arrested on December 1, 1955, in Montgomery, Alabama, for
refusing to give up her seat on a bus to a white man. Her arrest was the
impetus for a boycott of Montgomery buses, led by Dr. Martin Luther King, Jr.,
and joined by approximately 42,000 African Americans for 381 days. On November
13, 1956, the United States Supreme Court ruled that Montgomery's segregation
law was unconstitutional, and on December 20, 1956, Montgomery officials were
ordered to desegregate buses. Rosa Parks refusal to surrender her seat in
compliance with Montgomery's segregation law inspired the civil rights
movement, which has resulted in the breakdown of numerous legal barriers and
the lessening of profound discrimination against African Americans in this
country. Her courage and conviction laid the foundation for equal rights for
all Americans and for the Civil Rights Act of 1964. Rosa Parks was the first
woman to join the Montgomery chapter of the NAACP, and was an active volunteer
for the Montgomery Voters League. She cofounded the Rosa and Raymond Parks
Institute for Self Development in 1987 with Elaine Easton Steele to motivate
and direct youth to achieve their highest potential through the "Pathways to
Freedom" program. She is the recipient of many awards including the
Presidential Medal of Freedom, the nation's highest civilian honor, the
Congressional Gold Medal of Honor, the highest honor Congress can bestow upon a
civilian, and the first International Freedom Conductor Award from the National
Underground Railroad Freedom Center. The naming was on the occation of Rosa
Park's 89th birthday. Named by Assembly Concurrent Resolution 134, Chapter 2,
28 January 2002.
In additional to the other designations noted, Route 10 (in its
entirety) has been officially designated the "Christopher Columbus
Transcontinental Highway", although on the east coast, the corresponding
sign is not on I-10 (it is on I-40). It acquired this name in Assembly
Concurrent Resolution No. 106, Chapter 71, in 1976. According to reports in
2003, the sign on I-10 has disappeared. The Continental Drifters appear to have
released a song about this route; the lyrics are
here and
here.

The I-405/I-10 Interchange is named the "Marilyn Jorgenson Reece
Memorial Interchange". It was named in honor of Marilyn Jorgenson Reece,
who was born and raised in North Dakota and earned a bachelor's degree in civil
engineering from the University of Minnesota in 1948. Ms. Reece moved to Los
Angeles with her parents shortly after graduation in 1948, and went to work for
the State Division of Highways, which later became the Department of
Transportation, as a junior civil engineer in Los Angeles. After six years of
experience required to sit for the Professional Engineers Exam, Marilyn
Jorgenson Reece became the state's first fully licensed female civil engineer
in 1954. In 1962, Marilyn Jorgenson Reece received the Governor's Design
Excellence Award from Governor Pat Brown for designing the I-10/I-405
interchange. Ms. Reece became the Division of Highway's first woman resident
engineer for construction projects shortly after receiving that award. The
three-level I-10/I-405 interchange designed by Marilyn Jorgenson Reece opened
in 1964 and was the first interchange designed in California by a woman
engineer. Urban critic Reyner Banham, author of <I>Los Angeles: The
Architecture of Four Ecologies</I>, admired the wide-swinging curved
ramps connecting the two freeways, and wrote that the I-10/I-405 interchange
"is a work of art, both as a pattern on the map, as a monument against the sky,
and as a kinetic experience as one sweeps through it". During her 35-year
career, Marilyn Jorgenson Reece's projects included serving as senior engineer
for the completion of Route 210 through Sunland in 1975—at the time, the
largest construction project the Department of Transportation had ever
awarded—at $40 million. After retiring in 1983, Marilyn Jorgenson Reece
taught engineering classes at Cal State Long Beach; and during Women's History
Month in 1983, the Los Angeles City Council honored Marilyn Jorgenson Reece for
making significant contributions to the city. In 1991, Marilyn Jorgenson Reece
received life membership in the American Society of Civil Engineers. Named by
Senate Concurrent Resolution (SCR) 72, Resolution Chapter 96, on 8/15/2006.
The Western Avenue overcrossing at I-10, in the City of Los Angeles, is
officially named the Reverend Cecil "Chip" Murray Overcrossing. It was
named in honor of the Reverend Cecil "Chip" Murray, who has generously and
successfully served the community and congregation of the First African
Methodist Episcopal Church in Los Angeles since 1977, when the congregation
counted 300 active members and those members received his vision to ignite a
fire in their hearts to be a church that extends beyond its walls. As of 2004,
the congregation numbered over 17,300 members, and works through more than 40
task forces, including task forces related to health, substance abuse,
homelessness, emergency food and clothing, general and specialized housing,
tutoring, entrepreneurial training, and employment services. These task forces
and programs provide notable assistance and services that include assistance
and services for the physically handicapped, dwelling assistance for low-income
individuals and those with HIV/AIDS, transportation for the elderly and
handicapped, education, health care and AIDS/tobacco ministries, tutoring,
legal aid, computer training, job training and placement, economic development
and loan programs, a business incubator for multimedia production, a prison
ministry, environmental programs, food programs, youth programs, choir and
music programs, and other activities. Reverend Murray served 10 years on active
duty in the United States Air Force as a jet radar intercept officer in the Air
Defense Command and as a navigator in the Air Transport Command, was decorated
in 1958 with the Soldier's Medal of Valor following an explosion in his
two-seated fighter, and retired as a reserve major in the United States Air
Force. He is a native of Florida and has received an undergraduate degree from
Florida A&M University, has received a doctorate in religion from the
School of Theology at Claremont, and has lectured and been an adjunct professor
at Iliff University, Seattle University, the School of Theology at Claremont,
Fuller Seminary, and Northwest Theological Seminary. Reverend Murray retired as
Senior Pastor of the First African Methodist Episcopal Church on September 25,
2004. Named by Assembly Concurrent Resolution 152, chaptered September 1, 2004.
Resolution Chapter 175.
The I-10/I-110 interchange is officially named the "Dosan Ahn Chang
Ho Memorial Interchange". Dosan Ahn Chang Ho was born in a small village in
Korea in 1878. He arrived in America in 1902 with his newlywed wife, Lee Hae
Ryon (Helen Ahn). As the steamship approached Hawaii, Ahn Chang Ho resolved to
stand tall above the sea of turmoil existing at that time in Korea, and
resolved to call himself "Dosan," which means Island Mountain. While living in
San Francisco, Dosan organized the San Francisco Social Meeting on September
23, 1903, and initiated a social reform movement that was in desperate need in
the Korean American society. As an accomplished orator and leader at the age of
24, Dosan guided his countrymen to form a respectable community for Koreans in
the United States. He and his family settled in Riverside, California, in March
1904 and worked tirelessly to unite Korean Americans and to revive the
patriotic spirit of the Korean people. He moved to Los Angeles in 1913, where
the Dorothy Chandler Pavilion now stands, and played a significant role in the
growth of the Korean American community in the City of Los Angeles. Together
with his friends, he formed the Gonglip-Hyuphoe, or Cooperative Association,
which would become the basis for the Korean National Association, which Dosan
later led as president. This association maintained structure within the Korean
American community, both to build character of individuals and to enhance the
image of Koreans within the mainstream community. Dosan also established one of
the first English schools for Koreans so that his fellow Korean Americans could
learn English and the Bible. He helped to relieve blighted living conditions
for his fellow Korean Americans in the Greater Los Angeles area, and became the
spiritual leader of the Korean Independence Movement. Following Japan's
annexation of Korea in 1910, Dosan formulated the basis for the Provisional
Government of Korea, and conceived Hung Sa Dahn (Young Korean Academy), an
organization to develop leaders for the independence movement, in 1913. In
1915, Dosan promoted the development of the Korean language program for second
generation Korean Americans as an opportunity to pass on Korean traditions,
values, and identity to younger generations. Through his work, Dosan Ahn Chang
Ho had an enormously beneficial impact and significance on the history of
modern Korea and Korean Americans. Dosan's philosophy and teachings serve as a
model for Korean American youths. The interchange was named in honor of the
100th Year Centennial Immigration for Korean Americans to the United States.
Named by Senate Concurrent Resolution 104, Chapter 160, September 11, 2002.

Approved as chargeable Interstate on 9/15/1955. At one time, Caltrans
proposed this as I-12, with I-10 being assigned to what is currently I-8.
|
-
From Route 101 near Mission Road in Los Angeles to the Arizona state
line at the Colorado River via the vicinity of Monterey Park, Pomona, Colton,
Indio, and Chiriaco Summit, and via Blythe.
|
In 1963, this routing was defined as "Route 110 in Los
Angeles to the Arizona state line at the Colorado River via the vicinity of
Monterey Park, Pomona, Colton, Indio, and Shaver's Summit, and via Blythe, and
includes that portion of the Colorado River highway bridge (near Ehrenburg,
Arizona) which is within the State of California. The department may contract
with the State of Arizona, for and on behalf of the State of California, for
the maintenance of such bridge." Route 110 referred to a stub route downtown
(in particular, the portion between the two segments of Route 10).
In 1968, the stub Route 105 and Route 110 were elimated, and the portion
from Route 101 to Route 5 was transferred from former Route 110. This changed
the routing to "(b) Route 101 near Mission Road in Los Angeles to Route 5. (c)
Route 5 in Los Angeles to the Arizona state line at the Colorado River...",
reflecting the slight discontinuity at Route 5.
In 1984, the two segments were comined, and the text about Arizona was
removed, giving the definition of "(b) Route 101 near Mission Road in Los
Angeles to the Arizona state line at the Colorado River via the vicinity of
Monterey Park, Pomona, Colton, Indio, and Chiriaco Summit and via Blythe."
Near the intersection of I-10 and former Route 31, Ontario had a
racetrack. Between 1971 and 1980, this track hosted Indycar/CART, NHRA, and
NASCAR events; this racetrack was designed in a similar shape to the more
famous Indianapolis Motor Speedway and was intended to bring a second venue of
major auto racing into the Los Angeles area (the first was the now-defunct
Riverside International Raceway, which is located at the I-215/Route 60
junction). This track also hosted the "Questor Grand Prix", an allstar event
attempting to prove whether American formula racers were superior to those from
Europe. After Ontario Motor Speedway went bankrupt in 1980, the track was
demolished and the land is now owned by ChevronTexaco. It was near where
Ontario Mills now stands, and might explain the car-named streets between Haven
Avenue and old Route 31: Dusenberg Drive, Ferrari, Mercedes Lane, Porsche Way,
and Concours, and the car named streets west of Haven Avenue: Triumph Lane,
Shelby Street, Shelby Lane, Lotus Avenue, Jaguar Way.

This segment was made up of four distinct parts:
-
Between Route 5 and San Bernardino, this was LRN 26. The initial
portion of the route, from Colton to Route 86 near Indio, was added in the
Second Bond Act of 1916. The route was extended between Monterey Park and
Colton in 1931. It was extended further into Los Angeles to meet US 101 in
1933. This portion was signed as US 70/US 99. This segment starts at the San
Bernardino Split, which was the end of US 60 and US 70, and junction with US 99
and US 101. The grade separated interchange was originally completed in 1943;
it was later modified by the addition of the flyover in 1954. In 1996, the
flyover was removed due to earthquake safety.
-
Between San Bernardino and Indio, this was also part of LRN 26.
This portion of LRN 26 was defined in 1916, and was signed as US 60/US 70/US
99.
-
Between Indio and Shavers Summit, this was part of LRN 64. This
segment of LRN 64 was defined in 1931. This portion was signed as US 60/US 70.
-
Between Shavers Summit and the Arizona state line, this was LRN 64.
The portion between Shavers Summit and Blythe was defined in 1919, and the
extension to the Arizona State Line in 1931. It was also signed as US 60/US 70.
In Blythe, this was Hobsonway, and used a different bridge to cross the
Colorado. The current bridge was built in 1960, with improvements in 1974. No
remnants of the original bridge remain.
On July 15, 1952, the California Highway Commission adopted I-10 as a
freeway. I-10 became part of the Freeway & Expressway System in 1959 and is
also part of the Interstate Highway System. I-10 is included in the State
Interregional Road Systems and is further classified as a “High
Emphasis” and “Gateway” route. The entire length of I-10 is
included in the National Highway System, the Department of Defense Priority
Network, and the Strategic Highway Corridor Network. The 1990 Federal Surface
Transportation Assistance Act (STAA) identifies I-10 as a “National
Network” route for STAA trucks. The Federal Functional Classifications for
I-10 are Rural Principal Arterial and extension of a Rural Principal Arterial
into an urban area.

According to an article in the San Gabriel Tribune, the I-10/I-605
interchange was designed in 1964 and was supposed to accommodate traffic until
1984. No major changes have been undertaken there since it was built. An
average of 438,000 cars use the interchange each day, making the intersection
the 19th busiest in the state. According to a 1999 study by the South Coast Air
Quality Management District, the area directly around the interchange has one
of the highest air-pollution- related cancer risk factors in the San Gabriel
Valley. One of the main problems with the intersection is what engineers call
"the weave,", where vehicles transferring from the I-10 west to the I-605 south
have to weave across cars getting on the I-605 south from the I-10 east. Cars
from both directions have only about 150 feet to change places with each other.
Additionally, drivers who want to transfer from the southbound I-605 to the
eastbound I-10 east have to take a left turn when leaving the I-605. According
to Caltrans, the prospects for improvements are bleak. Caltrans is considering
building a flyover from the I-605 south to the I-10 east, which would eliminate
the weaving-in section. The current budget crisis rules out state funding for
the immediate future, and it was not appoved for funding in the 2007 CMIA
allocations.
 A project has been approved for future
consideration of funding to construct the Live Oak Canyon Interchange in the
City of Yucaipa (TCRP #59). [April 2002 Agenda Item 2.2c.(3)]. The overall
project is to reconstruct the Live Oak Canyon Road Interchange on Route 10 and
construct the 14th Street Bridge over Wilson Creek. Construction of the 14th
Street Bridge was completed in December 2003. In 2007, the CTC considered a
request for modification of funding on this project, which would place the
completion date in FY 2008/09
In 2007, the CTC recommended using the Corridor Mobility Improvement
Account (CMIA) to fund widening of the ramps and addition of aux. lanes at
Cherry, Citrus & Cedar ($30,325K requested, $19,233 recommended) and a WB
mixed flow lane from Live Oak Cyn to Ford St ($38,186K requested; $26,500K
recommended).
There are plans to widen this route from Route 210 to Ford Street in
Redlands (TCRP #58) [September 2002 Agenda Item 2.1c.(2)]. The overall project
will add one mixed flow lane in the median in each direction on I-10 from
Orange Street to Ford Street in the City of Redlands. The proposed widening
will upgrade I-10 within the limits of the project from three lanes to four
lanes in each direction. This is now scheduled for completion in August
2007.
TCRP Project #61 will reconstruct the Apache Trail Interchange E of
Banning in Riverside County. As of September 2005, this project is
inactive.
![[Bob Hope Interchange]](maps/010-bobhope.jpg) In
November 2006, the CTC considered a route adoption to construct a roadway
extension and a new eight lane overcrossing over I-10, near Bob Hope Drive. In
the vicinity of the proposed Bob Hope Drive interchange, I-10 is an eight-lane
divided freeway. The existing Ramon Road interchange was constructed in 1961.
The proposed project will construct a new spread diamond interchange with Bob
Hope Drive. The interchange will be located approximately 0.4 miles west of the
existing Ramon Road interchange and will be a new six-lane overhead structure
over the Union Pacific Railroad and an eight-lane overcrossing structure over
I-10. The existing Ramon Road eastbound on-ramp will remain operational while
the other four ramps at Ramon Road will be removed. Keeping the eastbound
on-ramp at Ramon Road will improve the operating conditions at the local street
intersections. The proposed improvements will increase the capacity of the
existing interchange and improve interchange operations. This project is fully
funded in the 2006 State Transportation Improvement Program. The total
estimated project cost is $53,700,000. This project requires full oversight by
the Federal Highway Administration (FHWA) since it is a federally-funded
project on the interstate system that involves the reconstruction of an
interchange and is greater than $1.0 million. A FHWA field operations engineer
reviewed the project on April 12, 2006. A Modified Access Report was approved
by FHWA on February 15, 2002. This project is consistent with the Regional
Transportation Plan and the Riverside County General Western Coachella
Circulation Plan. As a “Gateway Interchange” to Rancho Mirage, all
improvements, including aesthetic treatment, landscaping, and restoration of
natural areas will be based on the conceptual plans provided by the Agua
Caliente Band of Cahuilla Indians. A public information meeting was held in
November 2001 to solicit public input. It is estimated to begin construction in
Fiscal Year 2007-2008.
2007 CMIA. A number of projects on I-10 in Los Angeles County
were submitted to the Corridor Mobility Improvement Account for funding. These
projects included HOV lanes, Puente Ave. to Citrus St. ($173 million); HOV
lanes, Citrus St. to Rote 57 ($191.5 million); and the I-10/I-605 transition
connector ($70.5 million). In San Bernadino County, a request for bridge
widenings in preparation for HOV lanes ($107,931K) was also non-recommended.
None were recommended for funding. This has been a point of contention
in the inland empire as there is significant congestion on the I-10.
The SAFETEA-LU act, enacted in August 2005 as the reauthorization of
TEA-21, provided the following expenditures on or near this route:
-
High Priority Project #391: Interchange improvements at the
I-10 and Indian Ave Interchange in Palm Springs. This was noted in the
Desert
Sun. $2,200,000.
-

-
High Priority Project #1387: Reconstruct interchange at I-10
and Riverside Avenue to improve traffic in Rialto. $1,600,000.
-
High Priority Project #1680: Implement Grove Avenue
Corridor/I-10 interchange improvements in Ontario. $2,400,000.
-
High Priority Project #2051: Improve interstates and roads

- Montclair and Ontario: Holt Blvd (former business route)
- E of I-15 along Valley Blvd through Colton (marked at least once).
- Indio: Indio Blvd. This doesn't dump you easily back onto I-10 on
the E side; you end up on Route 111 and then take the Route 86S expressway.
This routing is old US 99.
- Blythe: Hobsonway. This ends on the AZ side with an odd loop under
I-10 at the AZ border for E bound traffic.

The portion of I-10 located in California is designated the "Pearl
Harbor Memorial Highway". This segment was named in remembrance of
approximately 2000 brave and patriotic survivors of the attack on Pearl Harbor.
On December 7, 1941, just before 8 a.m. on a Sunday morning, the first wave of
bombers began the attack on Pearl Harbor that led the United States into World
War II. It was an unforgettable day for those who lived through it and one that
called America forth to defend itself. In so doing, it inspired a generation of
Americans to rise and lead the defense of freedom around the world. Overall, on
December 7th, 1941, 2,335 people were killed in action and 1,178 were wounded;
the majority of the Pacific Fleet that was damaged and sunk in the attack was
at one time home ported in California. Named by Senate Concurrent Resolution
(SCR) 8, Resolution Chapter 72, on 7/12/2005.
The portion of this freeway from US 101 to Route 215 is named the
"San Bernardino Freeway"; the first segment opened in 1943 and the last
segment in 1957. It was named by the State Highway Commission, based on its
primary destination of San Bernardino. San Bernardino was first recorded as a
place name in 1810, and derives from the name of the Italian saint of the 15th
century. In 1842 it was applied to a land grant, on a part of which Mormons in
1851 started a settlement, the nucleus for the present city. The mountains are
mentioned before 1850, the county was named in 1853, and the national forest in
1893.
The portion of this freeway between the intersection with Route 19 in
the City of Rosemead and the intersection with I-605 in the City of Baldwin
Park is officially named the "El Monte Police Officer Donald Ralph Johnston
Memorial Highway". It was named in honor of El Monte Police Officer Donald
Ralph Johnston. Officer Donald Ralph Johnston was born in Wichita, Kansas, on
November 11, 1954. When he was four, his parents moved the family to La Puente,
California where his father Corky joined ranks of the El Monte Police
Department. Officer Johnston graduated from La Puente High School in 1972, and
became the proud father of a son Eric who later continued the Johnston legacy
with the El Monte Police Department (3rd generation). In 1985, Officer Johnston
became a reserve officer for the City of El Monte until he became a full-time
officer in 1988. Officer Johnston volunteered in the Adopt-a-Cop program at
Wilkerson School. On January 9, 1990, Officer Johnston responded to a call of a
person trying to pass a bad check at a bank, and was shot and paralyzed by the
suspect after selflessly pushing a bystander out of harm's way. He was awarded
the City of El Monte Medals of Valor, Distinguished Service, and Purple Heart,
received commendations and awards from the United States Congress, Governor
Deukmejian, Governor Wilson, the California State Legislature, the Office of
Attorney General, the County of Los Angeles, the American Police Hall of Fame,
and numerous other local and national organizations. On January 29, 1991,
Officer Johnston returned to work at the El Monte Police Department in a
wheelchair, and was assigned to the Community Relations Unit as a detective
handling missing persons investigations, all the while continuing his community
involvement by mentoring disabled students. In 1993, Officer Johnston secured a
position as the first regular police helicopter observer, and was able to
experience the excitement of street patrol once again. Officer Johnston's work
was so exceptional that he received many accolades for his service; and in
1997, Officer Johnston developed the S.T.R.I.V.E (Success Through Recognizing
Individual Volition and Excellence) program, and visited schools to tell his
story and inspire students to overcome their own obstacles. After retiring from
active duty on September 1, 2001, Officer Johnston refused to quit, and with
his letter of retirement, submitted a request to stay with the El Monte Police
Department as a reserve officer, despite his declining health and chronic pain.
Officer Johnston passed away on November 22, 2002. Named by Assembly Concurrent
Resolution 71, Resolution Chapter 115, 8/25/2003.
Originally, the segment that opened in 1943 (from US 101 to Route 215)
was named the "Ramona Expressway". Ramona was the central character in
the Helen Hunt
Jackson novel
Ramona,
which was a seminal novel in the early 20th century in creating the romance of
California.
The portion of I-10 between Vincent Avenue and Grand Avenue in the City
of West Covina is officially named the "West Covina Police Officer Kenneth
Wrede Memorial Highway". It was named in memory of Officer Kenneth Wrede of
the City of West Covina Police Department, who was killed in the line of duty
on August 31, 1983, in the City of West Covina while responding to a call
regarding a suspicious person. Officer Wrede was a longtime resident of

The portion of I-10 in the City of Ontario between the 6th
Street overcrossing and the intersection of Euclid Avenue as the "Officer
Richard Hyche Memorial Freeway". It was named in honor of Officer Richard
Hyche, a four-year veteran of the Ontario Police Department. Officer Hyche was
fatally wounded on October 15, 1975, and at the time was the first Ontario
police officer killed in the line of duty since 1957. Officer Hyche was born on
April 27, 1944, in Long Beach; served in the United States Marine Corps;
attended the San Bernardino County Sheriff's Academy; worked at the Glenn Helen
Maximum and Minimum County Jail Facility for two years; and was hired as a
police officer by the Ontario Police Department on July 23, 1971. Officer Hyche
was killed by a single gunshot by a suspect being sought in connection with a
murder that had occurred the previous day at the Pepper Tree Motel. The suspect
was later convicted and sentenced to life in state prison, and subsequently
escaped from prison, fled to Montana, and was eventually killed after a deadly
crime spree. Officer Hyche is still remembered today by former supervisors and
colleagues as an excellent officer who was always outgoing and friendly, who
enjoyed his work as a police officer, and who had a strong commitment to his
fellow officers. Named by Senate Concurrent Resolution (SCR) 95, Resolution
Chapter 93, on 8/11/2006.
The portion of this freeway from the Beaumont Avenue/Avenue/Route 79
exit to the Sunset Avenue Exit, in the County of Riverside is named the "CDF
Firefighter Chris Kanton Memorial Highway". This segment was named in
memory of California Department of Forestry and Fire Protection (CDF)
Firefighter Chris Kanton, at 23 years of age, who died in the line of duty on
Saturday, August 6, 2005, in the County of Riverside. While responding to
storm-related accidents, CDF Firefighter Chris Kanton was traveling in a CDF
fire engine on I-10 east of Route 60 when the engine left the highway and
traveled down a steep embankment, struck several trees, and came to rest on the
roadway below. CDF Firefighter Chris Kanton, graduated from high school in 2000
in Paso Robles, California; attended and graduated from the Allan Hancock Fire
Academy in Santa Maria, California; and subsequently completed HAZMAT training

The portion of this freeway in San Bernardino and Riverside counties is
named the "Redlands Freeway". This is because the route traverses the
City of Redlands.
The portion of I-10 in San Bernardino County between mile markers 25.26
and 29.82 is named the "Officer James M. Goodman Memorial Highway". This
segment was named in memory of CHP Officer James M. Goodman, who was killed in
the line of duty on June 3, 2004. He was traveling west on his department
motorcycle in the City of Redlands, attempting to overtake a vehicle he
believed to be involved in a hit and run accident, when a van, traveling north
on Nevada Street, entered the intersection from the south directly in the path
of Officer Goodman. Officer Goodman was unable to avoid a collision and
broadsided the van, and thereafter succumbed to the injuries he received from
the traffic collision. He was born on September 11, 1955, in Martinez,
California, was raised in the Bay Area, and graduated in 1973 from Pinole High
School. He honorably served in the United States Army for nearly eight years
and dedicated four years to reserve duty, ultimately achieving the rank of
sergeant. Officer Goodman joined the California Highway Patrol on January 9,
1984. After successfully completing his training at the California Highway
Patrol Academy, he reported to the Redwood City area on May 24, 1984. On August
20, 1985, Officer Goodman was awarded a California Commission on Peace Officer
Standards and Training Basic Certificate; and on April 1, 1987, Officer Goodman
transferred to the San Jose area. On May 2, 1989, he was assigned to the

numerous certificates of achievement in the field of law enforcement. While
stationed in the Oakland area, Officer Goodman was the first officer to arrive
on scene after the Loma Prieta Earthquake occurred on October 17, 1989; and on
the day of the earthquake, Officer Goodman helped to release a driver trapped
under a collapsed portion of I-880 by crawling through a small space only
accessible by removing several pieces of his safety equipment. For three hours,
while the highway continued to settle from aftershocks, he and his colleagues
worked to free the driver. In honor of this heroic act, he and two other
officers were awarded the Medal of Valor by Former Governor Pete Wilson.
Additionally, on November 25, 1989, Officer Goodman received a Meritorious
Award from the office of the Mayor of the City of Oakland for his valor,
gallantry, and courage during the 1989 earthquake. Officer Goodman made
significant contributions to traffic safety and to the motoring public while
serving at each assigned area and served for 20 years as a sworn peace officer
for the California Highway Patrol. He was known by his fellow officers for his
outstanding dedication to the department and to the protection of the citizens
of our state. Named by Assembly Concurrent Resolution (ACR) 41, Resolution
Chapter 72, on 7/3/2007.
The portion of this freeway from a point just west of the Route 111
cutoff in the Palm Springs area to a point at the bottom of the grade east of
the City of Coachella is named the "Sonny Bono Memorial Freeway". As if
you didn't know the story, Sonny Bono left his boyhood home in Detroit,
Michigan for Hollywood, California at a young age to become a star in show
business. His quest led him to a laborer's job as a meat truck driver and
deliveryman and then in promotions for a record company. Sonny Bono parlayed
those jobs into an opportunity to showcase his ability as a showman and
entertainer. Those talents eventually led to a career of fame as a recording
and television star as part of the duo Sonny and Cher. Later, Sonny Bono
pursued another dream as a restaurant owner in Palm Springs. His concern on
behalf of his community as a businessman led him to public service eventually
leading to his election as Mayor of Palm Springs in 1988. Sonny Bono's public
service career eventually led him to the halls of the Congress of the United
States in 1994 as the Representative from the Coachella Valley and Western
Riverside County areas of southern California. Sonny Bono's achievements as a
Congressman brought needed national attention to the environmental needs of the
Salton Sea; he also worked on behalf of bringing the needed federal funding for
transportation and infrastructure projects for the Coachella Valley, leading to
funding for significant highway improvements throughout the Coachella Valley
and Riverside County. Named by Assembly Concurrent Resolution 25, Resolution
Chapter 58, June 4, 2001.
The portion of this freeway near Indio in Riverside County between the
Jefferson Street and Indio Boulevard interchange and the junction with Route 86
is officially named the "Doctor June McCarroll Memorial Freeway." Doctor
June McCarroll arrived in California in 1904, when she moved to Indio in order
to place her ailing husband in a health camp for persons infected with
tuberculosis. In Indio, she traveled, at first by horse and buggy and later by
horseback, to practice medicine on five Indian reservations. She later became
the doctor retained by the Southern Pacific Railroad to treat its employees in
the Coachella Valley. In later life, she expressed regrets that younger doctors
were seemingly unable to function without modern hospitals and other
conveniences when she had sometimes operated on kitchen tables, explaining "I
would clear off the table, tie the patient down, and administer the
anesthetic". She is also credited with starting the first library in the
Coachella Valley. She is also known for her role in initiating the painting of
centerlines upon streets and highways. The Riverside County physician, who was
known as Dr. June, was driving home one day in 1917 when a truck forced her car
off the road. Convinced that lines would help drivers stay safely on the
correct sides of the road, McCarroll took her idea to Riverside County's Board
of Supervisors and Chamber of Commerce. When they didn't do anything, she set
an example by painting a mile-long, 4-inch-wide white stripe down the center of
Indio Boulevard, near her home. In 1924, after she and the Indio Women's Club
and the California Federation of Women's Clubs proposed it, the idea of
painting a centerline on state highways was adopted by the California Highway
Commission. The credit for painting white traffic arrows on pavement,
incidentally, apparently belongs to George S. Hinckley, a traffic engineer who
first used them in the plaza in front of Redlands City Hall in 1910. Named by
Senate Concurrent Resolution 58, Chapter 105, August 17, 2000.
The portion of this freeway extending five miles to the east and five
miles to the west of mile marker number 84 in Riverside County, located east of
the Chiriaco Summit, is officially designated the "Veterans' Memorial
Freeway". This is in honor of the veterans that have served the United
States from the state of California. Named by Assembly Concurrent Resolution
No. 137, Chapter 104, in 1994.
This portion of this freeway from Route 86 near Indio to I-5 in Los
Angeles is designated as part of "Historic US Highway 99" by Assembly
Concurrent Resolution 19, Chapter 73, in 1993.
In additional to the other designations noted, Route 10 (in its
entirety) has been officially designated the "Christopher Columbus
Transcontinental Highway", although on the east coast, the corresponding
sign is not on I-10 (it is on I-40). It acquired this name in Assembly
Concurrent Resolution No. 106, Chapter 71, in 1976. According to reports in
2003, the sign on I-10 has disappeared. The Continental Drifters appear to have
released a song about this route; the lyrics are
here and
here.

HOV lanes have been constructed from Hebert Street in downtown Los
Angeles to I-710 in El Monte. This is called the "El Monte Busway". It
opened in January 1973, requires three or more occupants, and is in operation
24 hours a day.
HOV lanes also exist from the San Bernardino County line to I-15. They
require two or more people, and operate 24 hours a day.
HOV lanes are planned as follows:
- from I-405 to I-110
- from Baldwin to I-605
- from I-605 to Puente Avenue
- from Puente Avenue to Citrus Avenue
- from Citrus Avenue to Route 57
- from Route 57 to the San Bernardino County line.
![[TCRP Project 40]](maps/010-tcrp-40.jpg) Segments (3), (4),
and (5) are the subject of District 7 TCRP Project #40, which plans to add HOV
lanes to this segment, for a total cost of $210 million. The estimated
completion date is 1Q2008 for the segment from I-605 to Puente Ave, 1Q2010 for
the segment from Puente to Citrus, and 1Q2012 for the segment from Citrus to
Route 57. A negative EIR (a good thing) came back in February 2004. However,
due to funding, the schedule has been pushed back. In April 2006, the CTC
considered requests approval of a TCRP project application amendment for
$56,900,000 in new TCRP funding that would program $56,900,000 in TCRP funds to
Construction; redistribute $4,194,000 from Plans, Specifications, and Estimates
(PS&E) to Construction; redistribute $757,000 from Right of Way to
Construction; and update the project funding plan. The project will provide for
approximately 11.2 miles of HOV lanes that will effectively double the people
carrying capacity of a mixed flow lane thus alleviating some of the congestion
by encouraging and supporting the use of shared ride modes. The project will be
delivered in three segments, with Segment 1 (Route 605 to Puente Avenue) fully
funded with TCRP, STIP-RIP, and Proposition C funds. The current schedule is:
Phase 1: FY 2002/2003; Phase 2: FY 2010/2011; Phase 3: FY 2010/2011; Phase 4:
FY 2013/2014. Some of these were submitted for funding from the 2007 CMIA
allocations, but none were recommended for approval.
In his
2006
Strategic Growth Plan, Governor Schwartzenegger proposed constructing HOV
lanes from Puente to Route 57 in LA County.
As of late 2007, there were some proposals to convert some future lanes
E of I-605 into High-Occupancy Toll (HOT) lanes.
There are also some HOV lanes in the segment from I-15 to Route 57, but
these do not extend for the entire portion.
