From Route 126 near Saticoy to Route 210 near San Fernando.
Note: There is a discontinuity in the postmiles for Route 118 along "New" Los Angeles Avenue -- i.e., the segment of Los Angeles Avenue between the Route 118 / Route 23 freeway junction and where Route 23 continues N along Spring Rd. This is because the postmiles in the segment technically belong to Route 23.
This segment remains as defined in 1963.
In 1954, route studies were conducted for the Simi Valley Freeway (Route 118) from Desoto Avenue to the proposed Foothill Freeway (public hearing held January 9, 1964); and from the Route 126 Freeway near Saticoy to First Street near Moorpark.
In 1964, a 19.3-mile freeway routing for Route 118 was adopted between six-tenths mile west of La Vista Avenue near Saticoy and three-tenths mile east of First Street near Simi. A routing was also adopted in 1964 between 0.3 mi W of DeSoto to the future I-210 routing.
The first segment to be constructed was between Kuehner Drive in Simi Valley and Santa Susanna Avenue (likely current Topanga Canyon). In July 1964, the CHC adopted a freeway routing for the western portion of Route 118. The routing ran E-ly to beyond Winnetka Ave, then NE-ly to where it is north-of and adjacent to the DWP power transmission lines S of Rinaldi St. It continues E along this right of way, bending SE-ly E of Balboa Blvd to E of Woodley Ave, then E-ly across I-405 and I-5. It then swings NE-ly beyond Laurel Canyon Blvd, and continues N of and parallel to Paxton St. to join to I-210 just E of Foothill. This routing affected 174 fewer families while costing $2.9 milllion less than the next most favored routing. Later in 1964, a 19.3-mile freeway routing for Route 118 was adopted between six-tenths mile west of La Vista Avenue near Saticoy and three-tenths mile east of First Street near Simi.
Construction of the Simi Freeway required excavation of 8.5 million cubic yards of earth for roadway, and over 34,000 cubic yards for structure excavation. Fills ranged up to 220' in depth, requiring special drainage structures. In some areas the unique rock strata required a 3-to-1 cut, and the right of way at its widest point is 1,100' from top of cut to top of cut. The summit between Ventura County and Los Angeles county is at 1,568', with the grade being 3.6% on the Ventura side, and 5% on the Los Angeles side
The following freeway-to-freeway connections were never constructed:
In 1987, it was reported that Caltrans was closer to connecting Route 23
(the Thousand Oaks-Moorpark Freeway) and Route 118 (the Simi Valley
Freeway) in Moorpark, with state and federal approval expected in Spring
1989. Once that happens, Caltrans can proceed with engineering plans and
purchase additional right of way. The state agency already owns 70% of the
needed land. Construction is to begin in 1990 and end in 1993, and the
freeway will run along Los Angeles Avenue about 200 feet from the nearest
homes. The 2.2 mile, $40 million freeway connector is one of the biggest
public works projects under way in Ventura County. The proposed route
would extend Route 23 north [Actually, it was Route 118 that was extended]
from the intersection of New Los Angeles Avenue, through about six acres
of wetlands and up to Los Angeles Avenue just east of Princeton Avenue in
the College Park area. The freeway would then swing east along Los Angeles
Avenue and hook up with the existing Route 118 just east of College View
Avenue. In a letter signed by 1,100 local residents, a homeowners group
asked Caltrans to consider an alternative route that would cut south into
ecologically sensitive wetlands and the Simi Arroyo instead of traveling
along Los Angeles Avenue. But Caltrans declined, noting that the southern
route would cost $10 million more, eat up four more acres of wetlands and
make future freeway expansion more difficult because of its remote
location. Caltrans officials also say that studying a southerly
alternative would push the entire project back two years and might
jeopardize state and federal funding. The freeway connector is on a list
of state projects to be built in the next five years and most elected
officials support the proposed route. Both Route 23 and Route 118 received
the green light from the California Highway Commission in 1964. About
seven miles of Route 23 had been completed by 1971; the Route 118 link to
Simi Valley was completed in 1975. But plans to finish and connect the
freeways stopped that year when Caltrans ran out of money. It was not
until 1988 that the connector for the two highways was again included in
the State Transportation Improvement Program and elected officials as well
as civic leaders today say they want to make sure the freeway is built.
Caltrans plans call for a four-lane highway with an exchange at New Los
Angeles Avenue and Collins Drive, an undercrossing at Los Angeles Avenue,
two two-lane bridges over the Arroyo Simi and the Southern Pacific
Railroad, and an interchange at either Princeton Avenue or Condor Drive.
The price also includes seven-foot sound walls for residential areas (at
$1 million per mile), right-of-way land, room for an additional two
freeway lanes as needed, engineering and environmental reports and
mitigation measures that the agency is required by law to take. Caltrans
must create six acres of new wetlands to replace the federally protected
wetland that will be paved over for the freeway, and plant 300 oak trees
to replace 150 that lie in the construction path. Moorpark College manages
and maintains the site which is used as a nature center by the
environmental science program. The project involves moving about 1.8
million cubic yards of dirt and the use of 60,000 cubic yards of concrete,
and includes seven bridges, rising to a maximum height of almost 100 feet.
They will carry traffic across the Southern Pacific railroad tracks, the
Arroyo Simi and Moorpark’s surface streets. The project, initially
budgeted at $33 million, was slated for completion in April 1993, but bad
winter weather and the need to clean up a large waste dump along the route
delayed the work and pushed the cost up to about $39 million, and pushed
completion to October 1993.

When the freeway to freeway connection was made between Route 118 and Route 23 in 1993, there were some interesting road name changes. Previously, the freeway portion of Route 118 ended at College View. The surface routing ran out of Simi Valley along Easy Street and Los Angeles to Collins, and then continues along Los Angeles curving S and then W to Spring Road (where Los Angeles became High Street). Route 118 then ran S along Spring to Los Angeles Avenue, continuing W along Los Angeles to Ventura. At the intersection of Los Angeles and Spring, Los Angeles Ave was extended E to Route 23 as "New Los Angeles Avenue". When the freeway-to-freeway connection was completed and opened, it was constructed on top of the old portion of Los Angeles Avenue between Collins and Princeton Ave. The "surface" route then was changed to run up Collins to Campus Park Dr and over to Princeton. Princeton was upgraded between Campus Park Dr and where it met Los Angeles, and Los Angeles Avenue was renamed Princeton Ave, until, as before it turned into High Street at Spring. This allowed "New" Los Angeles Avenue to drop the "New", and the interchange at the Route 118/Route 23 join became simply "Los Angeles Avenue".
Note that the original plan was for Route 23 to be freeway all the way to Santa Paula. As part of that plan, there would have been a full connection between Route 23 and Route 118, with Route 118 continuing E/W Northerly of Los Angeles Avenue on a new alignment to meet the Route 232 freeway between Santa Clara and Vineyard Avenue, remining on new alignment Westerly of Los Angeles to Route 126. This is shown in a 1983 Thomas Guide in my possession.
This segment is one of the original signed routes dating back to 1934. Before the freeway, it ran along Telephone Avenue in Ventura (while Route 126 was on Telegraph), Los Angeles Avenue, Santa Susanna Pass Road, and Devonshire Blvd. It then ran N along Sepulveda to Brand, N on Brand into the city of San Fernando. It jogged N on San Fernando Rd a bit to Maclay, and then N on Maclay to Foothill Blvd. The portion between Route 126 and I-5 was defined in 1933; the remainder was defined in 1909. A small portion in Ventura was LRN 154 until 1957.
This segment was LRN 9 and was signed as Route 118 when state routes were first signed in 1934 (Jct. US 101 near El Rio to Jct. US 66 at Pasadena, via San Fernando). LRN 9 was originally defined in 1909 running from San Bernardino westward to LRN 4 (what became US 99) in San Fernando. LRN 9 was extended westward to LRN 2 (US 101) near Montalvo (modern day Ventura) in 1933. LRN 9 encompassed portions of the original routing of US 66 (San Bernardino to Pasadena) and Route 118 (Pasadena to Ventura).
Devonshire Street was named for the Devonshire area of Britain, after beginning life in 1917 as Santa Susana Pass Road. Brand was named after Leslie Brand, a street car magnate and developer who lived in the Glendale area and subdivided Mission Hills. Maclay was named after Charles Maclay, town builder and former state Senator, who was the founder of San Fernando
Before 1964, Route 118 continued down Foothill Blvd. Around the Devils Gate Reservoir, there was a small freeway segment [since bypassed], connecting it to Montana. It then ran along Montana to Lincoln Ave, then to Colorado St. in Pasadena, where it ended at US 66. Portions of Foothill Blvd have been known as Horsethief Trail, Michigan Avenue, Tujunga Valley Avenue and Mulholland Street. Before that freeway segment was built, it appars to have run (this is in the reverse direction): N up Lincoln Avenue to Montana, turned W to Arroyo Blvd, N to La Canada Verdugo Road, W over the dam, continued NW past Oak Grove Park on the R, skirted Flintridge Country Club on the E, joined Michigan Ave (now Foothill Blvd), continued W. The entire portion from the intersection of Cañada Ave and Montana to Foothill Blvd is now under I-210; the former Country Club is now the site of two high schools. As of the late 1950s, Route 11 (now Route 110) turned NW from Lincoln on Cañada Ave to Montana, then followed (according to the map) Montana two blocks to Arroyo. The present Cañada Ave. still joins Montana at approximately the same place, but I-210 is built over the continuation W to La Cañada Verdugo Road, now under the overpass at Arroyo Blvd.
Note: the use of this route as "Temporary" I-210 is discussed with Route 210.
A portion of this (from Foothill Blvd. near Gould Ave. east to near the intersection of Montana Ave. and Cañada Ave.) was constructed to freeway standards in 1957, but was bypassed and decommissioned as "freeway" in 1974, when I-210 was constructed over the Arroyo Seco.
By 1935, the surface alignment of Route 118 absorbed what was then US 99
on LRN 9 between San Fernando and Pasadena, with US 99 being rerouted
along LRN 4. This move occurred because the State Legislature removed
restrictions that prevented State Funds from being used to maintain urban
roadways. This change by the Legislature led to the addition of numerous
urban highways being adopted including the extension of LRN 9 to Ventura.
Originally US 99 had bypassed downtown Los Angeles in favor of using LRN 9
from San Fernando via the following route:

According to Gribblenation, 1935 maps show all the roadways described
above between Pasadena and Los Angeles signed as Foothill Boulevard. The
alignment of Route 118 appears to take a simplified route from US 66/LRN 9
on Colorado Street up Fair Oaks Boulevard and Lincoln Avenue to Foothill
Boulevard on a bypass of Altendena.

A 12.5-mile portion of the route between Los Angeles Avenue at Madera Road in Ventura County and De Soto Avenue in the City of Los Angeles was adopted by the California Highway Commission in 1962. The remaining portions to the west and to the east of this adopted segment are currently under planning study with a target date for adoption late in 1963. First construction was planned for the five-mile unit of the adopted route between the easternmost end of Simi Valley and De Soto Avenue in the West San Fernando Valley. An estimated $12,000,000 was believed necessary to finance that construction.
Planned as freeway from Route 126 to Route 23 but never upgraded. Freeway from Route 23 to Route 210.
In February 2009, the CTC received notice of preparation of an EIR for reconstruction of the Route 118/Route 34 interchange in Somis. The proposed project would construct roadway improvements that include relocating and realigning Route 118 at Donlan Road, and adding a westbound left-turn lane in the westbound direction of Route 118, an eastbound auxillary lane, and interchange ramp improvements along portions of Route 118 and Route 34 intersection in the community of Somis in Ventura County. The project is included in the State Highway Operation and Protection Program Long Lead Project List. Future funding for project design, right of way, and construction will be programmed later pending completion of the environmental clearance. The alternatives being considered are:
Moorpark officials reviewed the draft EIR, and believe that it fails to take into account a plan by Ventura County to realign Donlon Road so that it joins to make a four-way intersection where the two state highways meet. They also believe that it does not provide mitigation of an expected increase in truck traffic and related air quality, noise and safety impacts on Route 118 as a result of projects planned by Caltrans.
In October 2012, it was reported that Caltrans has dropped plans to revamp the Somis interchange. Caltrans will include its decision in the project's environmental impact report that will be issued by the end of November 2012. The county now wants to realign Donlon to make a four-way intersection at Route 118 and Somis Road. According to the county, Caltrans can make "easy, quick and cheap fixes" in conjunction with the county project, such as lengthening a left-turn lane from westbound Route 118 to Somis Road.
In March 2015, it was reported that the intersection of Route 118 and Somis Road will start construction in May to improve the traffic flow and create a fourway stop. In February, 2015 the county paid $88,000 for a one-third-acre lot next to the intersection. The right of way will allow road crews to reroute Donlon Road in order to create the four-way stop. The Ventura County Public Works Agency has already removed 25 eucalyptus trees on the newly purchased land. Project engineer Chris Hooke said it was critical to cut the trees down before nesting season starts in March. Some of the birds that nest in the trees include the endangered American peregrine falcon and the golden eagle. Hooke said the birds’ nests would have halted the project until the summer. Donlon Road currently connects 200 feet east of the intersection; the side road makes it difficult for drivers making left-hand turns. Additionally, the length of the left-turn lane on Route 118 will be nearly tripled, from 120 to 350 feet. Construction at the intersection is expected to take eight months, at a cost of about $2.5 million.
In April 2016, it was reported that the Donlon Road
realignment project in Somis had been completed. The job involved moving
Donlon Road 200 feet to the west to align with the existing traffic signal
on Route 118 at Somis Road/ Route 34.

In April 2021, it was reported that 5 drainage culverts (Fox
Barranca/North St. (~ 07-VEN-118-10.089), La Cumbre Creek Culvert
(07-VEN-118-11.1), the Long Canyon Creek underpass (07-VEN-118-012.98),
Wailing Siren Culvert (07-VEN-118-13.76), and Meijo Creek
(07-VEN-118-014.53)) had been retrofitted into wildlife crossings. The
retrofitting made them accessible for wildlife and added fencing to funnel
animals to them. Overall, the effort has involved an initial year-long
study of wildlife movement, mortality, and crossing use, then the
acquisition of funds for the retrofits followed by the construction work
of modifying the culverts and adding fencing, and finally
post-construction wildlife monitoring. Some culverts that had almost
no use prior to the retrofitting of ramps are now seeing wildlife use
almost daily. At the Long Canyon underpass, an almost 10-foot-tall cement
wall on its north end proved to be a hindrance for wildlife attempting to
cross beneath the highway. The mitigation here consisted of building a
long concrete ramp allowing animals to walk down into the culvert. Fencing
was also installed on the north side of the road to funnel animals onto
the ramp, while the south side is a natural funnel, so no fencing was
used. At another culvert, dubbed Fox Barranca, there was previously a
6-foot drop with a pool of water at the bottom. Caltrans workers installed
“riprap,” which filled in the drop with boulders of varying
sizes. This created a natural-looking ramp into the culvert, especially
after soil fills in the spaces around the rocks and plants begin to grow.
Animals have started to regularly use this natural ramp as well. Caltrans
maintenance crews are reporting picking up less roadkill along the stretch
that includes the five crossings. One of those crossings was a black
bear in a box culvert known as LaCumbre, where a steel ramp was installed.
The retrofits are mostly complete and are now being monitored by wildlife
biologists using remote cameras to assess how well their efforts have
succeeded. As many as 10,000 images are being captured each month by

In November 2019, it was reported that the city of Moorpark is exploring
options to increase the safety of Route 118 in Moorpark (VEN 15.571 / VEN
R17.894). Since the city incorporated in 1983, Moorpark has dedicated more
than $16 million to improvements on Los Angeles Avenue. The
roadway’s funding, though, was mostly supported through
Moorpark’s residential and commercial developments that are required
to make contributions to both the city’s traffic mitigation efforts
and the Route 118 improvements. The money has helped the city make
enhancements to the area by widening parts of the roadway, adding traffic
signals and planting new landscape. But, according to Moorpark, the
thoroughfare still has a long way to go until it meets the city’s
expectations. High on the city’s priorities list is eliminating
unsafe driving and truck traffic along the highway; widening the road
between Spring Road and Moorpark Avenue; and adding a raised median on
parts of the avenue, among other improvements. Moorpark officials are also
working with the Ventura County Transportation Commission and the
California Department of Transportation (Caltrans) to expand the
frequently-used roadway and make it safer. Since 2016, the agencies have
worked together to re-pave Route 118 and to re-program traffic signals to
increase speeds and reduce wait times. Caltrans also approved a city
project to install a raised concrete median between the Route 23 Freeway
and Spring Road (technically, part of Route 23). The city is also working
to complete a right-of-way designation along the roadway to widen L.A.
Avenue to three lanes in each direction between Spring Road and Moorpark
Avenue. The city hopes it can finish designs for those plans by the end of
2020. In the future, Caltrans plans to devote $17 million to resurface
Route 118 between Spring Road and Montair Drive. The city is also pushing
for Caltrans to install a traffic signal at Millard Street. Looking to the
future, Caltrans plans to devote more than $20 million to replace the two
truck scale facilities west of the city. The project, though, is still in
the planning stages.

Route 118 Arroyo Simi Overhead Suicide Prevention (07-Ven-118 T18.4/T18)
In June 2018, more than a dozen suicide-prevention signs line the overpass that connects the
Simi Valley portion of Route 118 with the N/S portion that connects with
Route 23 at Los Angeles Avenue. The signs were installed in the hope of
saving lives along the 2.2-mile stretch of road that crosses above Los
Angeles and Princeton avenues. Since the overpass was built in 1993 and
the installation of the signs in 2018, 11 people have jumped off the two
100-foot-tall bridges, according to the Moorpark Police Department. In
2014, after a 57-year-old Simi Valley man jumped from the overpass, the
Moorpark City Council sent a letter to Caltrans asking them to safeguard
the bridge with a fence. However, a fence is not feasible because these
are curving bridges and a fence would block the driver’s line of
sight. Three years later, in December 2017, Caltrans held an environmental
hearing on the future widening of Route 118 between Los Angeles Avenue and
Madera Road. During the meeting, Sean Corrigan, the city’s public
works director, said Moorpark would like to address the safety of the
overpass as part of the freewaywidening project. In the months that
followed, Caltrans decided to create signs for the bridges with help from
Didi Hirsch Mental Health Services, a nonprofit agency that provides mental health, substance abuse and
suicide prevention services to Southern California communities. Together,
the agencies developed freeway-appropriate signs in English and Spanish
with information about mental health resources and the National Suicide
Prevention Lifeline number. A total of 16 signs were installed between
July 5 and 12, 2018 with help from the California Highway Patrol.

Route 118 Widening in Simi Valley
In late March 2007, ground was broken on a $46M project
to add a lane to the freeway in Simi Valley. The work, expected to take
more than two years, includes not only widening the roadway from Tapo
Canyon Road (~VEN R27.317 to VEN R32.577) as it heads east into the San
Fernando Valley, but also the construction of sound walls along the
highway and fiber optics to better regulate the flow of traffic onto
freeway onramps. The second phase of the work is to begin in mid-2008 and
includes widening the westbound portion.
(Source: Ventura County Star, 3/30/2007)
In June 2007, Ventura County officials applied for an
additional $32.7 million to complete the improvements to WB Route 118. The
California Transportation Commission initially allocated $50 million for
the project but higher construction costs left only enough to add an
eastbound lane from Tapo Canyon Road in Simi Valley to the Los Angeles
County line. When the county officials originally asked for the additional
funds, the state Transportation Commission staff erroneously classified it
as a new project rather than a cost increase and recommended that the
request be rejected. If funding is turned down for the second phase, the
widening project will probably be delayed several years and the cost will
significantly increase. Local planners hope state commissioners will agree
to use a portion of funds from Proposition 1B — a $19.9-billion
statewide bond measure approved by voters last November — to finish
the widening project. Traffic on the stretch of the 118 Freeway increased
from 110,000 vehicles daily in 1998 to 117,000 today. With no improvement,
traffic planners estimate two-hour delays during morning and evening peak
periods each weekday will double by 2025. Ventura County is at a
disadvantage because it is the largest in the state without a local sales
tax earmarked for transportation projects.
(Source: Los Angeles Times, 6/6/2007)
In November 2007 and December 2007, the CTC considered a proposal to reprogram $1,206,000 for Environmental (PA&ED) for the Route 118 Widening project (New Los Angeles Avenue to Tapo Canyon Road, PPNO 3002) in Ventura County to the new Route 118 Widening Phase 2 project (Tapo Canyon Road to the Los Angeles County Line, PPNO 4006). The Route 118 Widening project between New Los Angeles Avenue and Tapo Canyon Road (PPNO 3002) was programmed in the State Transportation Improvement Program (STIP) for $4,660,000 for PA&ED with an unfunded need of over $110 million to complete the project through construction, but significant construction cost increases to higher priority projects in the region have resulted in the Caltrans and the VCTC deciding to delete the project from the STIP. The new Route 118 Widening Phase 2 project (PPNO 4006) is a much higher priority but requires funding for Design (PS&E) and Right of Way (R/W) Support. The adopting resolution of the 2006 STIP Augmentation, dated June 2007, included recognition of the high priority given by the VCTC to early programming of this project if capacity is available.
In May 2009, the Ventura County Transportation
Commission approved the allocation of $6.5 million to the ongoing widening
of eastbound Route118 through Simi Valley. It indicated that construction
will start in 2010 on phase 2: widening westbound Route 118 from three to
four lanes between Tapo Canyon and Kuehner Drive. It was funded earlier in
2009 as part of $1 billion in transportation spending approved in
Sacramento, which will also go to other transportation projects in the
county. An engineer’s estimate for the westbound Route 118 project
was $21.7 million dollars, and the Ventura County Transportation
Commission allocated the funds. However, when the California Department of
Transportation opened construction bids for the project on 11/5/2009, the
lowest qualifying bid was only $13.8 million by Sun-Valley based Security
Paving Co. The first phase of the widening project cost $46.5 million with
State Transportation Improvement Program funds, and included the addition
of sound walls, the widening of four bridges, and the addition of
communication and fiber-optic cables.
(Source: Ventura County Star, 11/19/2009)
In November 2009, the Ventura County Star reported the completion of the first widening phase of the project (from Tapo Canyon to the Los Angeles County line).
In February 2010, the CTC approved an adjustment to the allocation amount for the Route 118 Widening, Tapo Canyon to the Los Angeles County Line (Phase 2) project (PPNO 4006) in Ventura County, from $18,493,000 to $8,961,000, in accordance with Assembly Bill 608. Specifically, on May 14, 2009, the Commission approved Resolution STIP1B-A-0809-019 allocating $18,493,000 for the Route 118 Widening, Tapo Canyon to the Los Angeles County Line (Phase 2) project programmed in the State Transportation Improvement Program (STIP) with Regional Improvement Program (RIP) shares. The project was awarded on November 24, 2009, for $15,468,000 ($8,961,000 RIP and $6,507,000 Regional American Recovery and Reinvestment Act of 2009 [Recovery Act]), including supplemental work, state furnished materials, and contingencies. Section 188.8 of the Streets and Highways Code allows the Commission to adjust an allocation amount for a capital outlay project in the STIP if the construction contract award amount for the project is less than 80% of the engineer’s final estimate. As a result, Caltrans and Ventura County Transportation Commission requests a downward adjustment of the allocation from $18,493,000 to $8,961,000, with $9,532,000 to return to Ventura County’s regional share balance.
In March 2011, it was reported that the Route 118 Widening project was complete and open for traffic. Construction of phase one of the project, widening the eastbound highway from three to four lanes over a five-mile stretch from Tapo Canyon Road to the Los Angeles County line, began in 2008. Construction of phase two didn't begin until early 2010 because of funding issues. It added a new westbound lane along the same stretch, and completed the widening of the final two sections of the new eastbound lane. The second phase cost $19.1 million and was funded by Proposition 1B funds, state gasoline sales tax revenue and federal stimulus money. Phase one was completed strictly with state funds. A third phase of the project, which would widen the highway to Moorpark, is not even on the drawing board because of a lack of funds.
In February 2022, it was announced that as part of
Gavin Newsom’s $1.1 billion Clean California initiative, Caltrans is
awarding funding for beautification projects along the state highway
system. One project is the State Route 118 Simi Valley Beautification.
The project will enhance six interchanges in Simi Valley by replacing
dying ground cover with aesthetically pleasing rock cobble. Native,
drought tolerant plants to control erosion and provide pollinator habitat
will be planted in selected areas at local streets to enhance the visual
experience for the local community. As the community requested, each
interchange will receive a different plant palette and hardscape or
aesthetic motif to provide a unique place-making aesthetic to each
location. Estimated cost: $3.924 million. Estimated completion
date is June 16, 2023.

The Ventura County Star, in December 2009, had a nice article on "smiley face hill" (~ VEN R30.401). This is/was a 120-foot creation on the side of a hill in eastern Simi Valley created
originally by Sonny Klamerus, 58, of Northridge. By creating the giant
smile, it was his intention to invoke the same in drivers who passed by
the area near Yosemite Avenue and Kuehner Drive. The hill, which sits on a
10-acre site, was purchased by Palmdale 47th LLC in September 2009 from
the bank. The previous owner, Larwin Co., filed for bankruptcy protection
after putting a housing development project on hold in 2007. The face was
originally established in 1998 without the permission of its then-owner,
Mount Sinai Memorial Park (they later gave permission, as did Larwin).
Palmdate 47th finally granted permission in early 2010. The property has
changed hands several times and the area next to the hill is now marked to
be developed with 66 town houses according to the city of Simi Valley. The
new units will not obscure the grinning symbol. In 2014, Steve Apostolof,
who operates a pizza restaurant in Chatsworth, went out and bought $100
worth of solar lights, recruited some friends and illuminated Happy Face
Hill. The hillside grin has also gotten its own Facebook page, which has been "liked" nearly 7,000 times, according to page creator Brian Dennert, a world history teacher at Simi
Valley's Royal High School.

There are currently plans to add new on and off ramps at Rocky Peak Road (~ VEN R32.414): an EB off-ramp and a WB on-ramp. This western half of the interchange was graded and gated at the time of initial construction in 1968. This is a $9.1 million project. In August 2008, Caltrans released a bid to construct the EB off-ramp and the WB on-ramp at Rocky Peak Road. Prior to this construction, there were just dirt ramps. This construction was completed in 2009.
The SAFETEA-LU act, enacted in August 2005 as the reauthorization of TEA-21, authorized $2,320,000 for High Priority Project #124: Landscaping Enhancements along the Ronald Reagan Freeway, Route 118, for aesthetic purposes.
In August 2016, the CTC approved $31,477,000 for Los Angeles 07-LA-118 R0.0/R14.4 Route 118 in the city and county of Los Angeles, from Ventura County line to Route 210; also on Route 27 (Topanga Canyon Boulevard) from Devonshire Street to Route 118. Outcome/Output: Rehabilitate 65.0 lane miles of roadway to extend pavement surface life and improve ride quality. Replace approach slabs and upgrade curb ramps to meet current ADA standards.
In October 2003, the Simi Freeway served as a major firebreak for a fire that started up near Route 126 in Piru, and burned as far south as Browns Canyon and Chatsworth, as far East as Moorpark, and as far West as Stevenson Ranch. The fire burned a number of signs on the freeway, including the sign shown to the right (~ LA R0.5).
In March 2016, SHOPP funding was approved in Los Angeles County for westbound Route 118 at Tampa Avenue Off-ramp (~ LA R4.728). Outcome/Output: Widen Off-ramp to improve intersection operations.
Reseda Offramp Sinkhole (07-LA-118 R5.8)
The first report on the sinkhole was in March 2019 with a tweet from District 7:
"#PorterRanch: The westbound SR-118 Reseda Blvd Off-ramp is closed due to
a developing sinkhole. Caltrans geologist and maintenance are on site. The
ramp will be closed until further notice."

In October 2020, the CTC received notice of the
following supplemental emergency G-11 allocation: $2,350,000. 07-LA-118
R5.8. PPNO 07-5608; ProjID 0720000158; EA 1XP90. Route 118 In the city of
Los Angeles, near the community of Porter Ranch, at Reseda
Boulevard. On May 7, 2020, maintenance crews discovered a localized
pavement depression and a failed culvert underneath. This project
will replace the damaged culvert, reconstruct impacted embankments, and
reconstruct the damaged roadway. Allocation: CON ENG $700,000; CONST
$2,000,000. (Additional $100,000 was allocated for right of way purposes.)
Initial G-11 Allocation 07/27/2020.

While engineering was in process, the depressed portion
of the roadway was blocked off. In April 2022, the growth of the sinkhole
had increased to the point where the offramp had to be closed.

In September 2022, additional information on the
closure of the Reseda Blvd off-ramp was provided by Caltrans. The source
of the closure was the collapse of lanes two and three of the off ramp,
which was caused by a broken connection at the storm drain manhole on
Rinaldi. The broken connection was 25' underground. The drainpipe that is
underneath the off ramp had also collapsed. This resulted in pavement
separation and cracking, as well as pavement dips. The plan was to remove
and replace 260' of the damaged 78" diameter metal culvert pipe with a 78"
diameter reinforced concrete pipe. The broken connection to the storm
drain manhole on Rinaldi Street would also be repaired. The embankments
and landscaped areas would be reconstructed, and the irrigation system
would be replaced. The delay in the start of the project from the original
allocation in July 2020 was due to: (a) the required permit from the City
of Los Angeles to perform repair work on Rinaldi Street; and (b) the fact
that the procurement of the reinforced concrete pipe required the approval
from Caltrans and City. There were also delays in the fabrication of the
concrete pipe; it was due to be delivered in mid-October. Assuming the
permits are issued by the city in September 2022, the timeline for repair
was to start construction in early October 2022, with completion by the
end of 2022. The contractor would be working longer shifts 7 days a week.

$2,350,000 (CON ENG $850,000; CONST $1,500,000) on 12/6/2022 was necessary
because the cost and complexity of removing the existing 78 inch culvert
resulted in higher costs due to a wider excavation and longer permit
approval times, as well as a greater need for traffic control work and
reconstruction of more irrigation systems. Total: $5,050,000.

In February 2023, it was reported that the ramp, closed
for motorist safety in April 2022 due to a sinkhole. was originally
scheduled to reopen by the end of 2022, but work was delayed by winter
2022's above-average rainfall, which over-saturated the soil within the
project boundaries. The reopening has been rescheduled to mid-April 2023.
The remaining lanes on the ramp are anticipated to reopen by this summer

Commuter lanes exist on Route 118 between the Ventura County line and Route 5. These lanes were opened in March 1997, require two or more occupants, and are in operation 24 hours a day.
Officially, the portion of this route constructed to freeway standards (~ VEN T18.238 to LA R13.933) is named the "Ronald
Reagan Freeway" (as of 1994). The original proposal for this name
was introduced by Willie Brown on August 30, 1994 and amended August 31,
1994, as Assembly Concurrent Resolution 156. However, this version of the
bill died on the desk in November 1994. The name was reintroduced by
Senators Lockyer, Maddy, and Wright as Senate Resolution 7, amended and
enrolled December 5, 1994. Since it was neither a concurrent resolution
nor a joint resolution, it was not filed with the Secretary of State.
Ronald Reagan, for those who don't know, was the 40th President of the
United States. He was Governor of the State of California between 1967 and
1975. The rationale for choosing Route 118 is that the western end of the
Route 118 Freeway, at the time the bill was passed, is very close to the
Ronald Reagan Presidential Library.

Until 1994, the official name for the portion in Ventura County (~ VEN T18.238 to VEN R32.577) was the "San Fernando Valley-Simi Valley Freeway", and the portion in Los Angeles County (~ LA 0.000 to LA R13.933) was the "Simi Valley-San Fernando Valley Freeway". This portion was named by Assembly Concurrent Resolution 145, Chapter 185, in 1970. The first segment opened in 1968. Simi is probably from a Chumash Indian designation for "place" or "village"; it was recorded with the present spelling as early as 1795. San Fernando refers to both the community and the mission. The mission was established in 1797 to honor Saint Ferdinand, King of Castile and Leon in the 13th century. The city was named in 1874.
The First Street Overcrossing of Route 118 in the City of
Simi Valley (~ VEN R23.823) is named the "Simi Valley Police Officer
Michael Clark Memorial Overcrossing". It was named in memory of
Michael Clark, who was born in Massachusetts in August 1966. His family
later moved to Ventura County, and he was raised in Thousand Oaks, where
he graduated from Westlake High School in 1984. Michael Clark served in
the United States Marine Corps from December 1984 to August 1988 as a Navy
diver, assigned to “A” Company 3rd Reconnaissance Battalion
and stationed in Kaneohe Bay, Hawaii. Michael Clark achieved a life long
goal of becoming a police officer when he joined the Los Angeles Police
Department in May 1989. He was assigned to the Devonshire Division, where
he served as a patrol officer. Officer Clark later joined the Simi Valley
Police Department in March 1995, where he also served as a patrol officer.
On August 4, 1995, Officer Clark was killed in the line of duty while
handling a “check the welfare” call at the request of the
Ventura County Mental Health Department at a residence in Simi Valley,
where he was shot with a semi-automatic handgun by the person he was
attempting to assist. Officer Clark was the first Simi Valley police
officer to die in the line of duty. It was named by Assembly Concurrent
Resolution (ACR) 134, Res. Chapter 120, Statutes of 2016, on August 16,

The overcrossing on Route 118 at Balboa Boulevard (~ LA R7.813) in the County
of Los Angeles is named the “Los Angeles County Sheriff’s
Deputy Joseph Solano Memorial Overcrossing”. It was named in
memory of Deputy Joseph Gilbert Solano of the Los Angeles County
Sheriff’s Department, who was tragically shot on June 10, 2019, in
the City of Alhambra and ultimately succumbed to his injuries on June 12,
2019. Deputy Solano faithfully served the residents of the County of Los
Angeles as a deputy sheriff. Deputy Solano stated that the reason he
became a law enforcement officer was to be a role model and to make a
positive difference in other people’s lives, and as a deputy
sheriff, he was praised by his peers, supervisors, and members of the
community for his tireless efforts to protect people, prevent incidents,
and serve as a leader. Named by Senate Resolution SCR 24, Resolution Chapter 85, 07/16/21.

The interchange of Route 118 and
I-5 in the City of Los Angeles (~ LA R11.33R) is named the "David M.
Gonzales Medal of Honor World War II Memorial Interchange". It is
named in memory of David M. Gonzales, Private First Class (PFC), United
States Army. Gonzales was born in 1923 in East Los Angeles and raised in
Pacoima, California. David M. Gonzales joined the Army during World War II
on March 31, 1944, at Fort MacArthur, and was deployed to the Philippines
as an infantry replacement in December 1944. PFC Gonzales’ heroic
service on the Villa Verde Trail in Luzon, Philippines, on April 25, 1945,
earned him, posthumously, the Congressional Medal of Honor. On April 25,
1945, PFC Gonzales and his unit, Company A, 127th Infantry, 32nd Division,
were pinned down by enemy fire when a 500-pound bomb exploded in the
company’s perimeter, burying five men of Company A. Without
hesitation, PFC Gonzales seized an entrenching tool, and, under a hail of
fire, crawled 15 yards to his entombed comrades, while his commanding
officer, who also rushed forward to help, was struck and instantly killed
by machine gun fire. Undismayed, PFC Gonzales set to work swiftly with the
entrenching tool, and continued to dig out the five trapped men, while
enemy sniper fire and machine gun bullets struck him. After PFC Gonzales
had successfully freed one of the men, he stood up to be able to dig
faster, despite the fact that such a position exposed him to greater
danger, and while he successfully freed another man, PFC Gonzales was
mortally wounded by enemy fire as he finished liberating the third trapped
man. In the words of President Harry Truman, “Private
Gonzales’ valiant and intrepid conduct exemplified the highest
tradition of the military service”. The other two buried soldiers
were later saved when the intense enemy fire subsided. PFC Gonzales was
killed on April 25, 1945, while serving our country and saving the lives
of his comrades on the field of battle during World War II. PFC Gonzales
was survived by his then 25-year-old widow, his one-year-old son, and his
mother. Named by Senate Concurrent Resolution No. 72, Resolution Chapter
148, September 05, 2014.

[SHC 263.6] From Route 23 to DeSoto Avenue near Browns Canyon.
From Route 210 near Sunland to Route 249 north of La Cañada.
This segment remains as defined in 1963. Planned as freeway in 1965, but never constructed. Technically, this is signed along Route 210 from Paxton Street to Sunland. The traversable local routing was along Big Tujunga Canyon between Foothill and LA County Sign Route N3 (which appears to what would have become Route 249). There are no plans for improvement. See Route 249 for some further detailed discussion.
According to the 2013 Traversable Highways report, the closest roads are Big Tujunga Canyon Road with no plans for improvement.
With respect to Big Tujunga Canyon, Scott Parker on AARoads noted (in
response to a question about whether there were plans to expand Big
Tujunga Canyon): The original canyon road emptied out onto Mt. Gleason
Ave., a 2-lane local street; its connector down into the canyon was
characterized by horseshoe curves and switchbacks -- slow going. An
extension was built in the late '70's, about the time I-210 was being
constructed to the area. The idea was to skirt the floodplain below
the canyon on its south side and intersect Foothill Blvd. at the Wentworth
Ave. intersection (I-210 crossed Wentworth about a quarter-mile west of
Foothill). A number of new housing tracts were planned along the new
Tujunga Canyon extension -- but that area was considered environmentally
sensitive, and those never materialized due to permit denials. The
extension was built to Oro Vista Avenue, which paralleled Mt.Gleason to
the west; canyon traffic now is diverted to that street. It never
reached Foothill; a golf course was constructed directly in its path south
of the Tujunga Creek channel.

This routing was LRN 266 (defined in 1959) in 1963. It was not signed as Route 118.
The following segments are designated as Classified Landscaped Freeway:
|County||Route||Starting PM||Ending PM|
[SHC 253.1] Entire route. Added to the Freeway and Expressway system in 1959.
Overall statistics for Route 118. This information reflects Route 118 before the Route 118/Route 23 flyover connector was constructed; hence, there might be a mile or two difference in the traversable miles:
In 1933, Chapter 767 defined the route from "[LRN 2] near Salinas to Coast Road near Castroville" as part of the highway system. In 1935, it was codified as LRN 118 with the definition:
This definition remained unchanged until 1963. It ran from US 101 near Salinas to Route 1 near Castroville, and is present-day Route 183.
